Introduction Baldwin-Wallace College has taken great strides in the area of sustainability: it has both a sustainability major and minor—the first college to do so in Ohio, it has three buildings dedicated to sustainability (Ernsthausen, the Science Center and CIG) and it is committed to installing many new sustainability technologies such as wind and solar. The fall semester 2010 Green Business course has now completed a preliminary Carbon Footprint Analysis of the college. A carbon footprint is a measure of the impact of our activities on the environment, and in particular its ramification for climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation etc. Establishing a baseline for our current use of resources and carbon output will help the college to take tangible action steps to reduce our carbon emissions. Not only will this aid Baldwin-Wallace in being more sustainable, it will also provide the school with recommendations that can save thousands of dollars every year. An additional plus would be the college’s recognition among the many institutions that have used this or other carbon-footprint metrics in their efforts to reduce their environmental footprint. The Clean Air – Cool Planet Carbon Calculator We used the Clean Air – Cool Planet carbon calculator, one of many that are available, for the following reasons: It is free and it has been recommended by AASHE (Association for the Advancement of Sustainability in Higher Education; B-W recently became a member) and by the ACUPCC (American College & University Presidents Climate Commitment). 4 In our data collection, we used the equity-share approach, i.e., we only measured the emission of sources and facilities that B-W owns. That includes for example all buildings on the main campus (lecture halls and labs, administrative and utility buildings dorms, etc.) but not the facilities at B-W East since they are leased. (The alternative would be the more comprehensive control approach, which would include everything that B-W is using, but B-W does not really manage those buildings.). We collected data for the three fiscal years of 2007, 2008, and 2009 in order to establish a baseline that represents the average energy usage of the college. There are some limitations to our data: o Some data were just not available, such individual electricity consumption for individual building because we do not yet have metering devices installed in all of them. o For some categories it was unpractical to retrieve data (gas & diesel for Buildings & Grounds). In that case we only collected data from the most recent academic year (2009) and assumed that the previous years’ consumption was identical. o We also conducted a survey (commuter) during the spring of 2010, i.e., outside our selected time range for the baseline. Again, we extrapolated the data and expanded them for the previous three academic years, assuming similar commuting behavior for all four academic years. o Some data are not included because their addition or omission would not make a big difference (yet; as is the case for biodiesel), or they were difficult to come by. 5 o We have all been doing this for the first time and some data collection could have been done more efficiently or better streamlined. In spite of these shortcomings we now have a good baseline from which we can gauge and determine changes for the future. For further information on the Carbon Calculator, Clean Air – Cool Planet, please consult the Calculator User Guide that accompanies the Campus Carbon Calculator. It can be found at http://www.cleanaircoolplanet.org/toolkit/inv-calculator.php A Carbon Footprint Analysis consists of analyzing data from all areas of the college to see how much carbon dioxide (CO2) (and its equivalents) we produce. These carbon-emitting areas have been separated into three scopes, according to three levels of responsibility for emissions that an institution has, directly or indirectly, control over. 1. Scope One consists of sources of carbon emissions directly owned or controlled by the college, such as our vehicle fleet. Four groups in the class focused on this vast area: the Natural Gas, Vehicle Pool, Gas and Diesel, and the Refrigerant groups. Reducing emissions will be easiest in these areas because B-W has direct control over these emissions. 2. Scope Two is an area with less control than Scope One, -- indirect emissions. These emissions are from sources that are neither owned nor operated by B-W but are directly linked to energy consumption on-campus. The largest focus for this Scope is electricity, since we do not own our own generator, but rather purchase our electricity. We offer several suggestions for reducing our emissions in this area. 3. Scope Three is dedicated to “optional” emissions made by the school; ones that are neither owned nor operated by B-W but are attributed to the school, through activities 6 associated with our campus. This includes commuting, faculty travel, and study abroad. Other Scope-3 targets that could be considered for carbon-footprint measurements in the future are the effects of solid waste management, and emissions associated with paper production, food production etc. Having calculated our carbon footprint is not useful unless we also understand why it is important. Establishing where we produce the most carbon will help determine areas that we can most efficiently and effectively reduce those emissions for the benefit of the planet, but also reduce financial costs substantially for the college over the short and longterm. In addition, B-W can create a greater sense of community by uniting students, faculty, and staff around campus-wide goals. So that the college can become a more responsible citizen of the world, as it invokes its own students to become, we advocate that the college boldly exercise its leadership within the region’s academic and corporate communities through the immediate creation and careful monitoring of carbon-reduction goals. As leading sustainable corporations have already begun this institutional journey, so should Baldwin-Wallace College. Consistent with larger global carbon reduction initiatives, we recommend that the college adopt the goal of “20+ by 2020”. As an institution, our campus leadership, including president, Board of Trustees, and senior management, ought to rise to the challenge of reducing our carbon emissions by at least 20% by the year 2020. At the very least, this allows the college to begin the process of shrinking its own carbon footprint at a pace that will be necessary to stave off the worst possible climate change scenarios projected for the second half of our century, when the next generations of students, faculty, and administrators will reside in our places at this college47. Our college, and all comparable 7 institutions today, has the ingenuity, creativity, managerial expertise, and technology, necessary for this task. It is only a matter of will and institutional priority. There is no other undertaking more vital to the future that can wait for another day. 8 III. Natural Gas Our world is in a fragile state and it is important that each individual and institution know their harmful impact on the Earth’s delicate balance. Although difficult, we have tackled emissions of natural gas produced by Baldwin-Wallace College and have developed a greater understanding for the needs of the campus related to this resource and sustainability. We offer recommendations regarding heating, ventilation and air conditioning (HVAC) systems, insulation, windows, roofing, paints and glosses to help reduce carbon emissions by 20% by 2020. Our 2007 data shows that all buildings produced 784,704 CCF (or hundred cubic feet). Emissions produced in 2008 increased to 1,018,226 CCF. However, in 2009 they decreased to 877,528 CCF. The increase in CCF in 2008 is curious due to the fact that average low temperatures for all three years are within .9 degrees Fahrenheit of each other (42.7, 41.8, 42.3). Although in 2008, Cleveland had the snowiest March on record, the lowest temperature of the year was 1 degree Fahrenheit, which is relatively warm considering in 2009 the lowest temperature was -13 degrees Fahrenheit. More research must be done to try to identify the cause for the significant increase in natural gas consumption. However, this information provided us with an average and baseline for our work. It also offers B-W significant room for improvement. Heating, Ventilation and Air Conditioning Systems, although difficult to change immediately, provide long lasting changes toward a positive environmental transformation. Costly and cumbersome, these systems may not be low-cost for our goal of reducing B-W’s carbon emissions by 20% by 2020, but the impact of these systems must be 9 addressed as it is an extremely important factor for the overall carbon footprint of the college. B-W is taking significant strides to become more sustainable by adopting geothermal heating and cooling systems with large construction renovations. With every addition or renovation of a large building on campus, a new geothermal system replaces the old, outdated, standard natural gas system. The college has added a geothermal system to Ernsthausen Residence Hall, The Center of Innovation and Growth, The Life and Earth Sciences Building, and plans for sections of Merner-Pfeiffer Hall to use geothermal. Geothermal eliminates the need for natural gas, excluding some superficial usages, such as the fireplace in Ernsthausen Hall, but ultimately produces no emissions. Research shows that geothermal is one of the most efficient ways to heat and cool buildings without producing carbon emissions31. Geothermal is effective because a large pumping system is placed underground tapping into the Earth’s constant temperature of 50 degrees Fahrenheit. In the winter the air is pre-warmed and then pumped inside the building. During summer months however, warm air inside a building is pumped out and into the ground. Although more expensive initially, we found through a personal interview that the payback period for a geothermal system is between six to ten years and B-W has seen a 40%-60% energy savings on the buildings that have already adopted this new system. This process ensures a sustainable, reliable and comfortable future for heating and cooling. CHP, or combined heating and power, is another innovative way to heat and cool buildings with the added element of power. While producing electricity, the system collects heat that is created in that process and transfers it to the space heating system, which is also connected to the gas line in case the heat needs to be supplemented. In 10 addition to providing warmth, the system also produces electricity. More research would need to be conducted to see if the relationship between the carbon emissions produced and electrical output would be more beneficial than harmful but nonetheless a CHP system would be more beneficial than a standard natural gas system. Information on the cost of a CHP system is all relative to the building however a system could payback as soon as five years after the project. For a better estimation consult, http://www.ornl.gov/cgi-bin/cgiwrap?user=chpcalc&script=CHP_payback.cgi. Williams College in Massachusetts converted to a CHP system in 2004. Their system initially cost $2.7 million, however they think that the payback will be realized sometime in 2009. For more information on their experience with CHP see, http://www.chpcentermw.org/rac_profiles/Northeast/WilliamsCollege%2520profile.pdf Although difficult to install immediately, insulation is a huge aspect of heating and cooling that B-W has been unable to realize in their quest to become more sustainable and energy efficient. After consulting with Buildings and Grounds Manager, Bill Kerbusch, it became apparent that insulation was not a high priority on campus. Providing better, sustainable insulation needs to become a priority in the construction and renovation of new and existing buildings. Cellulose insulation is a relatively inexpensive yet sustainable option for insulation. It is installed by spraying in insulation which is composed of 75-85% recycled paper fiber, which is mostly post-consumer use newsprint, and 15% boric acid, which acts as a fire retardant. Cellulose insulation has an R-value (measure of materials resistance to heat flow) of 3.6 to 4.036. 11 Recycled cotton insulation is beneficial to the quality of air, boasting no harmful chemicals, and also to the environment, helping cotton by reused as another material. Recycled cotton R-values range from 3.7 to 30 and provides no harm when installing. Greenbuildingsupply.com offers options on UltraTouch insulation varying from R-13 insulation that includes 10 batts for $93.67 per .88 square foot to R-30 including 5 batts for $100.76 for1.86 square foot. This option could improve the quality of air in buildings and also serve as an environmentally friendly selection. Vegetable oil based insulation is a spray-in type insulation that possesses qualities that provide reductions in airborne allergens, better air quality, insulate as well as give an air barrier, and is earth-friendly because it is derived from a renewable resource. The price of this product ranges from $1.45 to $1.65 per square foot and could increase energy efficiency up to 50%. This product could help B-W become more sustainable and healthier18. As B-W renovates and builds, new windows are continuously changed. However, it is important to consider sustainable factors while making purchasing choices for new windows. Characteristics that set energy efficient windows apart from standard windows are double panes, low-emittance coating and low-conductance spacers. All of these aspects provide benefits for heating and cooling a home. Double or triple pane windows provide more resistance to heat escaping in addition, low-emittance coatings help suppress heat flow, creating a more energy efficient and sustainable building. The payback period for this type of window ranges from 2 to 10 years. Double pane windows are located in Heritage Residence Hall, Ernsthausen Residence Hall, Constitution Residence Hall and seven other buildings on campus. Low-conductance spacers are materials that are used to provide 12 extra coverage between the window and insulation helping keep heat from traveling beyond the glass. Windows are an important part of creating an energy efficient, sustainable building and by selecting products that provide eco-friendly features BaldwinWallace will be positively influencing the environment and the bank account. After speaking with Bill Kerbusch, it is apparent that roofing is another aspect of sustainable design that B-W is unable to give high priority, surely due to financial cost. Although some changes have been made to increase the R-value and ultimately the energy efficiency of roofing systems, other options, standard and unique, can be employed to help reduce energy loss through heating and cooling. Reflective roofing helps lower energy consumption by up to 40%. In addition, it increases the efficiency of insulation and HVAC systems, and also takes stress off of each. Furthermore this system also reduces the Urban Heat Island Effect and urban air pollution which is an added bonus to combat harmful effects individuals have on the planet30. Milk jugs to tires to carpet and aluminum; there are many materials that are being recycled into sustainable roofs. Most roofing systems that boast this feature contain 60100% recycled material in their product, can withstand 100 mile per hour winds and have warranties that last fifty to sixty years and do not need any maintenance. Ecostar.com has other useful information that can provide more insight on this technology. Recycled Roofing will help keep junk out of the landfill and on your roof however will not contribute a great deal to the energy efficiency of the building23. The addition of green roofs on campus would help promote conversation of the college’s intent to decrease carbon emissions by 20% for the year 2020. A green roofing system requires a stable infrastructure and offers many positive benefits. It can reduce 13 energy costs by providing sound insulation and roofing benefits in addition to reducing the Heat Island Effect. Also, it can aid with storm water management and does not need to be replaced frequently. Furthermore, vegetation in addition to grass could be added and perhaps used as produce for any of the dining halls. The cost for an extensive roof, which is simple and less intrusive, varies from $9 a square foot to $25 a square foot and weighs only 10 to 50 pounds. Another option is an intensive roof which costs between $25 and $40 a square foot and can weigh anywhere from 80 to 120 pounds. A green roof would not only be unique and aesthetically pleasing it would provide great energy efficiency and be a sustainable step in the right direction37. The most cost efficient and least labor intensive option to help aid in the heating and cooling process of our campus could be the use of paints and glosses. By coating buildings with these special products, a reduction in energy usage will quickly follow. Light Reflecting paints and glosses will help reflect light off the building therefore reducing the amount of energy needed to heat and cool the building. Exterior surfaces can be changed by 50 degrees Fahrenheit by certain types of paint while interior surfaces can be altered by 15 degrees, drastically reducing the need for air conditioning in the summer and heating in the winter49. Heating and cooling can be a huge factor in energy savings and carbon reductions on our campus. Simple changes and more extensive projects over time will help B-W reduce our carbon emissions by 20% by the year 2020. Our recommendations should be thoroughly considered and implemented in the years to come in order to make any significant improvement. 14 IV. Vehicle Pool We offer various recommendations to reduce B-W’s carbon footprint through its use of campus vehicles. The first being for each vehicle, create a data log of gallons purchased, total mileage, date of purchase, total cost of fuel purchased and locations traveled. This system could possibly help B-W better identify inefficient vehicle use and propose more sustainable strategies for transportation on campus. Buildings and Grounds operates the majority of campus vehicles, most of which are older large vehicles with low gas mileage. We think B&G has much potential, over time, to lower our school’s carbon footprint. For example, during the winter, larger model trucks plow snow. However during the summer, B&G uses the same larger model trucks to do landscaping throughout the campus. In these cases snow isn’t an issue, and neither is time in order to get job done. In summer months, we suggest using smaller model vehicles to transport needed materials as well as keeping supplies in areas they plan to work in as to decrease the amount of trips taken. Regarding larger vehicles we recommend eventual purchase of vehicles with higher fuel efficiency and that are sized for specific tasks. For instance, the 2011 Ford Super Duty with a 6.7-liter power stroke V8 has 29.2 MPG. Ford offers “Flex Fuel” for all such vehicles. The Flex Fuel allows engines to run cleaner with higher fuel efficiency than standard models. Another possibility is the GMC Sierra 1500 hybrid. The hybrid model has all the 4x4 capabilities and all the power from the 6.0 liter V8. The hybrid engine is the first two mode hybrid propulsion system in a full size vehicle. The first mode is used at low speeds and light loads; in this mode the engine can choose from three ways to power it. The first is 15 electric power only, the second is engine power only and the third is a combination of the two. The second mode is primarily used at high speeds, the only time the V8 engine is using its full power is when certain conditions demand it such as towing, passing on the highway, and climbing steep grades. The hybrid engine will allow the truck to run on all electric power up to 30-miles per hour. We offer these models because of their more fuelefficient specifications and their capacity to fulfill important functions required at B-W27. Although the complete revamping of the vehicle fleet would be quite expensive, the savings in total gas consumption and reduction in carbon emissions would be immediate. By meeting with the Buildings and Grounds we could possibly allocate a sufficient amount of vehicles and with the remainders, they could be sold to put money towards the purchase of the new vehicles. The second department that provides significant opportunities for carbon reductions is Safety and Security. Although this department currently only has two vehicles, 2007 Chevy Trailblazers, use of these vehicles can probably incur higher fuel costs and carbon emissions. To combat this, we recommend that the college institute no idling policy, particularly since weather conditions do not always require heating or cooling in the vehicle. For warmer weather, a possible alternative to the Trailblazers could be an electric golf cart—they seat up to four and can travel up to 25 miles per hour, which is suitable for our small campus. The battery lasts up to 50 miles, and the motor only runs if 16 the accelerator is pushed. To our current knowledge, Case Western Reserve has similar vehicles currently implemented around their campus. Another alternative is the T3 series, which has zero gas emissions, and operates for less than 10 cents a day. All that has to be done to this vehicle is let it charge for 3 to 4 hours and it travels at speeds from 0 to 14mph. The next proposal is a Segway, which some departments could use to get around campus, such as Safety and Security and our parking services54. It travels up to 12mph and can last up to 12 miles if ran continuously. Another problem we see would be the tours held on campus for prospective students. Normally students commence the tours by walking, however many times they’re carted around in B-W vans instead, regardless of the weather. We believe the emissions that the vans produced are highly unnecessary; given the brief amount of time the people spend in the vehicle for each stop for the tours. Instead, we recommend a vehicle such as the GEM e6 model that runs on an all electric 7.0 horsepower engine, can carry up to 6 people and can travel 30 miles on one charge. It can also reach up to speeds of 25miles per hour. The cost is $12,995.0057. In sum, the college has tremendous opportunities to reduce its carbon footprint, not only through immediate changes in vehicle use with a no idling policy, and elimination of unnecessary transportation, amongst other things, but also by its phase-in of higher efficiency, lower carbon emitting vehicles. 17 V. Buildings and Grounds This section of the report focuses on the Buildings and Grounds Department’s use of gasoline and diesel and their contributions to the B-W carbon footprint. On average, per budgetary year, the Building and Grounds Department uses 16,024 gallons of gasoline costing $45,809 at $2.85 per gallon. Diesel fuel adds another 3300 gallons costing $9,537 at $2.89 per gallon. We offer recommendations to help reduce the use of these carbon producing fuels that cost thousands of dollars per year and contribute to greenhouse gas emissions. Engines that power buildings and grounds vehicles are major contributors to greenhouse gas emissions. As vehicles are replaced, we recommend that they be replaced with electric vehicles when possible, and diesel powered vehicles when electric is not possible. Buildings and Grounds currently has 13 Ford E-150 vans and 5 E-250 vans that serve as primary vehicles for staff to carry their equipment and supplies to the jobsite. Using electric vehicles, such as Miles Electric Vehicles that have been purchased by Case Western Reserve University, could be an excellent way to cut emissions of campus vehicles2. Not only do they pollute less than a vehicle powered by an internal combustion engine, but they are also cheaper, costing approximately $18,000 versus $27,000 for a new E-150 van. While not all vans could be replaced with electric vehicles, as an electric vehicle cannot carry as much as a van and their top speed is only 25mph, limiting their ability to leave campus, replacing half the fleet of vans would save thousands of gallons of fuel per year, reducing the fleet’s carbon emissions according to an interview with Eugene Matthews of Case Western University. 18 Unfortunately, pickup trucks and Kubota RTV’s used around campus cannot be downsized as they are needed for snow removal. These are all larger F-350 pickup trucks, which are diesel powered, as well as the diesel engines that are in the Kubota RTV’s. We recommend that the vehicles are powered on biodiesel. The campus has a readymade source from the fryers in the cafeteria, as well as the numerous restaurants within five minutes of campus. The fuel could be processed in the chemistry lab with the equipment that has already been purchased, and then used in vehicles powered by the diesel engines. This would not only recycle a product that the college would have to pay to dispose of, but it would reduce the amount of diesel fuel purchased by buildings and grounds. While not as clean as electric, B100 biodiesel offers emissions reductions of all major tailpipe gases by 75%13. The next suggestion for Buildings and Grounds is to convert more college lawn space into low maintenance garden space. Converting this space into flowerbeds, populated with native species, and low maintenance plants such as Bethlehem Sage, will reduce the amount of lawn that has to be mowed, and reduce emissions from gas powered lawnmowers. Also, allowing the grass to grow taller could reduce the number of times it has to be mowed. Currently, the lawn is mowed on an as needed basis to a height of three inches. Mowing shorter, to approximately two inches, and allowing it to grow longer, perhaps to four inches, could reduce the number of times it has to be mowed, and thereby reducing emissions produced by gas powered lawnmowers. We also recommend improving the record keeping system for Buildings and Grounds gasoline and diesel consumption. The Vehicle Emission Pool team proposed a gas records system to accurately monitor the ongoing fuel efficiency of vehicles by individually 19 recording the gallons purchased, total mileage, amount paid, and date of the fill-up. While this record keeping system monitors fuel efficiency, it can also be used to record the Buildings and Grounds gasoline and diesel consumption at their gasoline and diesel tank containers. The amount of gas or diesel received can be gauged in the tanks, along with the current odometer reading of the vehicle. This way, Buildings and Grounds would be able to efficiently monitor their use of gas and diesel, which provides more room for improvement by seeing which medium uses the most fuel and where fuel can be more proficiently used. In sum, implementing these recommendations can significantly lower its contribution our carbon footprint. 20 VI. Refrigerants Introduction This section of the report concerns Scope One refrigerant emissions specifically refrigerant emissions from air conditioning (A/C) units on B-W’s campus. Refrigerant Data Collection Initially, the team was provided records from Building & Grounds (B&G) detailing A/C maintenance on B-W’s buildings. After reviewing the records, the team determined that the maintenance records did not provide adequate information for determining accurate refrigerant emissions for the entire campus. With assistance from Larry Seitz, HVAC technician for B-W, we determined the buildings on campus that had A/C units, those that used geothermal systems and those that were currently being renovated for geothermal systems in the future. Mr. Seitz explained that the main refrigerant used in the A/C units on campus is R-22 (HCFC-22) with R-410a refrigerant being used minimally in new or geothermal units. (See Appendix A for campus buildings with A/C, geothermal systems and the type of refrigerant used). A meeting between Dr. Sabina Thomas and Mr. Seitz determined that the college contracts and utilizes two A/C maintenances services: The Smith & Oby Service Company and the Price & James Heating & Refrigeration Company. Refrigerant Data Analysis After collecting the refrigerant data, we sought analysis assistance from R. Scott Thomas, Director of Environmental Affairs, and Barry Culp, Corporate Environmental Affairs Project Manager, of The Sherwin-Williams Company. Per their recommendations 21 and calculation examples, we determined an estimate of refrigerant emissions for the campus. This was calculated by using the following factors: conditioned square footage of a building (ft2), 1 ton coolant per 500ft2, refrigerant R-22 with a global warming potential (GWP) 1700, charge of coolant 1kg/ton and estimated loss of emissions at 10% per year. The total estimated refrigerant emission loss per year was determined to be 427 lbs. The CO2 equivalent for this loss is 330 tons a year. Per this project’s required research period, the estimated refrigerant emission loss over the course of three academic years (20062009) is 1282 lbs. and the CO2 equivalent emissions is 988 tons. (See Appendix B for Refrigerant Calculations). RECOMMENDATIONS Many recommendations in this report are two-fold: they would not only reduce the reliance on A/C systems but they would also reduce energy consumption and the carbon footprint for the college. The short-term recommendations discussed are the least costly for the college to implement. The longer-term recommendations are more costly for B-W to implement campus wide. SHORT-TERM RECOMMENDATIONS Refrigerant and A/C maintenance record keeping The first recommendation for the college is to have B&G maintain accurate A/C records on refrigerant use and A/C maintenance. Currently, records are only kept by the contracted service companies when maintenance is completed. These records are not complete and the therefore the data are incomplete. Using the service company’s maintenance sheets as an example, an electronic database or worksheet that inventories the following is ideal: 22 XII. All buildings (campus and residential) that have A/C units XIII. Square footage of the building (ft2) XIV. Size of the A/C unit (type or #) XV. Refrigerant type used (e.g. R-22, R-410a, R-134a) XVI. Replacement/Leakage XVII. Service company that completed maintenance (Oby, Price & James) XVIII. Dates of maintenance XIX. Propellant used/1,000 ft2 XX. Amount of propellant recovered (lbs.) Amount of propellant needed (lbs.) Example Electronic Database A/C Record Building Square A/C Refrigerant Type footage Unit used Replacement/Leakage details Date of Propellant/ Amount of Amount of service, 1,000 ft2 propellant propellant needed (lbs.) (type which recovered or #) company (lbs.) Accurate record keeping will provide B&G better data to determine leaks and to determine an accurate estimate of emission loss. It will also provide data to implement a regular maintenance schedule which in turn can provide preventive maintenance measures 23 to be implemented. This would reduce refrigerant emission loss. In addition, a well maintained system runs more efficiently which will reduce energy consumption as well. The cost of establishing and implementing an electronic system through Microsoft Access or Excel would be minimal. Cost would be training employees on how to input the data into the system. B-W has a full service Information Technology (IT) Department on campus for development of a database and training. Increasing thermostat control set points 1-2 degrees during warmer seasons Last academic year (2008-2009), the Bonds Administration Building and Marting Hall were part of a test to determine energy savings. The temperature controls were reprogrammed in these buildings by 1-2 degrees to determine energy savings. Per Bill Kerbusch, Director of B&G, the test cycle was a success. As a result, B-W’s administration agreed to set heating and cooling temperatures in all academic and administration buildings (residential halls are an exception). Through B&G’s temperature management control, the heating thermostat temperature is set at 68o and the cooling thermostat temperature is set at 76o for these buildings. The second short-term recommendation is increasing building temperature controls by another 1-2 degrees. For example, we could increase temperature set points in later spring, summer and early fall seasons to 78o instead of 76o. With the higher set point temperature, the A/C system will run less often, for shorter periods of time and only when buildings are warmer. This practice not only ensures less stress on an A/C system but also, less use of refrigerants from possible emissions loss for running shorter periods of time. It also reduces energy consumption. 24 The cost for resetting the temperature control is nothing. The energy savings for increasing the temperature for each degree above 72 degree is 1-3% per degree21. Other heat reducing recommendations Other heat reducing options to cool buildings that require no or minimal financial cost are to the college are: turning lights off, opening doors and windows in place of A/C usage and planting trees to shade buildings. Lights are a heat generating source. Turning lights off in classrooms, hallways and buildings in warmer seasons and when natural light is available would reduce the amount of heat generated in a room or building. Opening doors and windows on seasonal days in place of using an A/C unit is an option as well. This can create a cross breeze that cools the building and would eliminate the use of a fans too which consume energy. Planting trees to shade areas or sides of buildings that receive the most intense rays of sunlight would cool buildings also. Trees planted to shade homes and/or office buildings have been shown to reduce A/C needs by up to 30%11. Trees would even create a positive feedback loop with the trees sequestering CO2 and releasing O2 into the air. The cost of planting a tree would be the highest in comparison to shutting lights off or opening doors and windows. It would include cost of the tree and cost of digging or excavating a hole to plant it. The cost could still be minimal if the tree was donated. The downside tree planting would be the time period in which it would take for the tree to mature to provide shade. Also, there is the possibility that adult tree roots can enter a ground water system or under foundations and cement sidewalks, wreaking havoc. To combat this, the tree would have to be strategically placed to avoid these types of problems. 25 Overall, implementing these simple practices would demand less from an A/C system and reduce energy consumption for B-W. LONG-TERM RECOMMENDATIONS Use of Dunlap white rubber reflective roofing on all roofs; painting rooftops of buildings white or cool colors We have learned from Bill Kerbusch that the college has installed Dunlap Roofing on several campus buildings. This type of roof is comprised of white rubber and therefore, has a reflective surface. In addition, the seams of these rubber roofs are heat welded together to create a durable seal. This type of reflective roofing has reduced energy consumption for B-W. Currently this type of rooftop is installed at Kamm Hall, Bonds Administration Building, Lou Higgins Recreation Center and others. A recommendation could be to have as many campus roofs as possible be Dunlap white rubber roofs. In addition, a long-term recommendation we are suggesting is a simple concept: paint flat building rooftops white and sloped rooftops in cool colors. The white or cool colored rooftop reflects sun back into the atmosphere and therefore, the building absorbs less heat. (This is contrary to black or dark rooftops that absorb heat.) A light-colored rooftop reduces the heat in a building and keeps it significantly cooler. Studies have shown that white flattop roofs reduce electricity use for A/C by 15% (Stephen Chu, Secretary of Energy)45. Less energy consumption reduces CO2 emissions and B-W’s carbon footprint. Cool colored rooftops are mainly found in southern or western states, and have not necessarily caught on in the Midwest. This is due to the Midwest’s four seasoned climate. Cool colored rooftops may reduce energy and emissions during the summer months but they would be a deterrent during winter months. During winter months, a dark rooftop 26 that absorbs the sun rays is ideal to reduce heating energy consumption. The benefits of painting rooftops in either white or cool colors would have to be weighed against having dark rooftops that absorb heat in winter months for the Midwest seasonal climate. The cost of this recommendation would be the cost of paint and labor for the building rooftops. A compromise to test the savings for cool rooftops may be painting some campus rooftops white and leaving others dark. Conversion of R-22 (HCFC-22) and R-410a to R-134a (HFC-134a, H-134a) refrigerant As previously mentioned, in a meeting with Larry Seitz, HVAC technician for B-W, we learned that the college uses R-22 as the main refrigerant for A/C systems. R-22 is a halocarbon (HCFC). It has a GWP of 1700, its emissions are ozone depleting, it’s a greenhouse gas and the manufacturing of this refrigerant contributes to climate change34. The amended Montreal Protocol of 1992 determined a phase-out of R-22. In 2010, the refrigerant cannot be used in new equipment. By 2020, production of the refrigerant will cease. At that point, recycled or recovered R-22 can be used in existing A/C equipment after 2020. The goal is a complete phase-out of the refrigerant by 205034. The main replacement refrigerant is R- 410a. R-410a is a mixture of hydro fluorocarbons (HFC) with 50% R-32 and 50% R-125. This mixture does not contribute to ozone depletion but it does contribute to global warming and climate change32,35. It’s GWP factor higher than R-22 172532. Therefore, we recommend substituting refrigerants R-22 and R-410a with R-134a (HFC 134a, H-134a) refrigerant where possible. R-134a has a significantly lower GWP at 1300.4 Use of this substitute refrigerant would greatly reduce emissions that contribute to 27 climate change. In the case of utilizing R-134a in place of R-410a, the reduction in CO2 over the course of a three year academic period would be 250 kg (See Graph 1). It is understandable that the substitute would have to work with already existing HVAC equipment on campus. But according to the Environmental Protection Agency’s website on Ozone Layer Depletion Alternatives –HFC 134a (R-134a, H-134a) is an acceptable substitute for R-22 and R-410a refrigerant33. Use of R-134a refrigerant is currently more cost effective as well. The price of R-22 is going to continue to rise as the phase-out process continues. Current prices for these refrigerants based on The Refrigerant Store website are as follows (priced per unit): the price of 1-2 30 lb. cylinder of R-22 is $195.0050; 1-2 25 lb. cylinder of R-410a $213.0051; a 1-2 30 lb. cylinder of R-134a is the cheapest at $175.0052. There is also a reduction in price for multiple cylinders ordered. Therefore, with the estimated calculation lbs. of refrigerant loss annually by the college (427lbs) to replace just the amount loss, the college would need approximately 15 cylinders (30 lbs. each) of refrigerant. The cost of 15 cylinders of R22 = $2520.00, R-410a = $2475.00, R-134a = $2265.00. R-134a is the cheapest.

Geothermal processes works by harnessing heat from underneath the Earth’s crust – the hot and molten rock layer called magma There are three designs for geothermal but all work mainly in the same way by extracting hot water and steam from the ground that has been warmed by the magma. The steam drives a turbine to generate power for the building. For ground-source heating and cooling geothermal pumps, the temperature of the ground is normally constant - around 50o degrees. Outside tubes and pipes run into the ground and from the ground into the building to ventilate the building. In the winter, the liquid moves heat into the building from the ground. In the summer, it moves heat out of the building to cool and runs it back down into the ground. These systems may have compressors and pumps to maximize heat transfer between the building and the ground source61. These ground-source heat pump geothermal systems have been shown to be very efficient in the summer. They are the most energy-efficient and environmentally friendly as well. They have been found to be more efficient than electric heating and cooling and can move as much as 3 to 5 times the energy they used to process power. In addition, the U.S. Department of Energy has determined that ground-source heat pumps for geothermal systems can save hundreds of dollars in energy costs each year61. Currently, B-W is using geothermal ground-source systems (also referred to as “vertical” geothermal systems) in a few buildings on campus. The first building to utilize a geothermal system was Ernsthausen Hall. The most recent building to use geothermal is 29 the Center for Innovation and Growth (CIG). The CIG does contain a compressor to assist in cooling in the summer months which does utilize a refrigerant – R- 410a. However, per Bill Kerbusch, the system only utilizes the refrigerant in the compressor area of the system and it does not circulating through the entire system like a conventional air conditioning system. Therefore, much less refrigerant is used in the system as opposed to a conventional central air conditioning unit that circulates refrigerant through the entire system. Furthermore, the compressor only initiates when the building temperature exceeds the temperature control set point thus, saving energy. Renovations on the Life & Science Building, Wilker Hall and McKelvey (with the possibility of the Conservatory) are all scheduled to include geothermal systems for heating and cooling of these buildings. With the success of the geothermal systems on campus, our long-term recommendation would be for all campus buildings to utilize this method of heating and cooling. Once again, as with the painting of rooftops, this recommendation is more costly (cost of excavating the dig, pipes, converting over equipment for ventilation purposes) and would have to be slowly implemented over time as opposed to other shortterm recommendations. From information that we received from Mr. Kerbusch, the cost and savings of a geothermal system versus a conventional A/C system is $500,000. LONGER-TERM RECOMMENDATION Rooftop gardens –“living rooftops”& vertical vegetative walls In William McDonough and Michael Braungart’s Cradle-to-Cradle they discuss the use of rooftop gardens on commercial buildings to heat and cool. A rooftop garden or “living rooftop” consists of: waterproofing membrane, insulation protection layer, drainage 30 layer, filter mat, soil layer and plant life44,56. The vegetation can be turf grass, shrubs or even trees.14 Roof-top gardens are a longer-term recommendation for B-W’s campus. Rooftop gardens are not only effective in insulating a building on cold days but also, they provide cooling in hot weather. It can protect the life of a roof by shielding it from the sun’s rays and provide storm water runoff protection44. In the summer, rooftop gardens can retain up to 70-100% of the precipitation that falls on them; in the winter they can retain about 40-50%. The reduction in the total annual runoff volume for both winter and summer is 50-60%25. Also, the plant life in the garden gives back to the environment by taking carbon dioxide in and giving off oxygen44. The strategy to implement rooftop gardens for B-W’s campus would be to determine if a building has the load-bearing capacity to support the weight of a garden. Both flat and sloped rooftops can be utilized for a rooftop garden. Turf grass rooftops weigh 5-30 lbs. per square foot and plant and vegetative gardens weigh 40-100lbs per square foot. B-W does have several older buildings and a structural engineer would need to be consulted with to determine if any buildings are structurally sound for the weight of a garden14. However, the investments in a garden rooftop can be cost-effective. The initial cost is estimated at 30% greater than a conventional roof. Cost projections can range from $33$55 a square foot for not only re-roofing but for installation of the garden. But garden maintenance in place of long term maintenance on a roof can prolong the roof up to 20 years while off-setting energy costs25. Plus, it removes refrigerants from the equation completely therefore, eliminating refrigerant cost, A/C maintenance, and roofing repair maintenance. Rooftop gardens also greatly reduce ozone depleting emissions and reduce to CO2 emissions that contribute to climate change. 31 Examples of Rooftop Gardens Kansas State University, Kansas41 Trent University, Canada20 Similar to the rooftop gardens, a new architectural structures consisting of vegetative walls (also called “vegetative fins”) are now being designed for use. Instead of 32 being built on top of a building, a vertical garden is grown on one side of a building. Fed by rainwater that is captured on the roof or “gray water” recycled from internal plumbing, this vertical garden changes with the seasons. The vegetation on the wall blooms in the warmer months creating shade to cool the building. In colder months, the vegetation dies off, allowing sunlight in to warm the building. The energy savings with a vertical garden are estimated between 60-65%67. Architectural designs have been drawn to implement a model like this on the renovation work for the Edith Green-Wendell Wyatt Federal Building which is a federal building in Portland, Oregon. The General Services Administration who is heading up the renovation work for this project states that the building could save as much as $280,000 in energy savings67. Example of Vertical Garden Architectural rendering – main Federal Building, Portland, Oregon67 33 VII. Electricity Introduction Team D focuses on purchased electricity, part of Scope Two institutional emissions, and offers a variety of recommendations how to reduce our carbon-based use of electrical energy. Electricity Data Electricity data presented is for all residence halls and apartments only. Complete data was not readily accessible for all academic and rental buildings. The total kWh for 2007 through 2009 was found by adding the kWh for each month for each year. The total kWh for 2007 was 5,106,315. Total cost was $408,505.20 based on the $0.08 per kWh cost in 2007. The total kWh for 2008 was estimated to be 5,137,735. Complete data were unavailable for the month of November; therefore, the total kWh was estimated based on previous data for that month. Total cost was $462,396.15 based on the $0.09 per kWh in 2008. The total kWh for 2009 was estimated to be 4,797,091. Complete data was unavailable for the months of July, August, and September; therefore, the total kWh was estimated based on previous data for those months(See Appendix E for total kWh by building and by month). Total cost was $575,650.92 based on the $0.12 per kWh in 2009. Recommendations Recommendations are prioritized as either short-term or long-term. Short-term recommendations are easiest and most cost-effective to achieve. Long-term recommendations are more difficult and/or costly to implement. Short-Term Recommendations 34 The college can immediately reduce electricity consumption by changing all incandescent light bulbs to compact fluorescent light bulbs (CFL). The elimination of all incandescent light bulbs should be the college’s first priority regarding electricity. An Energy Star qualified compact fluorescent light bulb uses 75% less energy and lasts about ten times longer than an incandescent light bulb43. The green business class counted 1,791 incandescent light bulbs on campus in March 2010. (See charts below for total light bulbs by building.) Of those light bulbs, 59 percent were college or faculty owned, while 41 percent were student owned. Most incandescent bulbs were found in personal lamps in students’ dorms and in faculty members’ offices. It would be cost effective to provide free compact fluorescent light bulbs to students and faculty for personal use. The payback period for two 32 watt CFLs is approximately 0.10 years. (Small Business Pollution Prevention Center)26. There are approximately 1,900 students living on campus and 167 full-time faculty members. We recommend that the school provide one compact fluorescent light bulb to each student living on campus and to every full-time faculty member for each school year. This totals approximately 2,100 bulbs, depending on the total of number of on-campus residents and faculty. As a direct result of this Carbon Footprint Project, Sam’s Club has agreed to donate 1,000 compact fluorescent light bulbs to Baldwin-Wallace for the 2010-2011 academic year. Because CFLs contain a small amount of mercury, the college should post information in all residence halls and academic buildings on how to properly clean-up broken bulbs and on how to dispose of CFLs. The posted information should include the following EPA recommendations: 1) If the bulb 35 breaks, open a window and leave the room for at least fifteen minutes to properly ventilate the area. 2) Carefully pick up glass fragments and place them in a sealed plastic bag before placing them in a trash container. 3) Wash your hands after disposing of the broken materials. Posting this information will ensure the safety of students and faculty when handling broken CFLs. We recommend that the college create a means for safe disposal of used CFL bulbs. Light Emitting Diode (or LED) lighting is another option the college should consider. Energy Star LED lighting uses at least 75% less energy and lasts about twenty-five times longer than incandescent lights43. LED lights are better at directing light in a single direction and are thus optimal for hallways and staircases. Inventory of Incandescent Light Bulbs Around Campus in March 2010 21 Beech Street 23 Alumni House 3 Bagley Hall 28 Bonds Hall 22 Carmel Hall 50 Conservatory 100 Constitution Hall 130 Dietsch Hall 40 Ernsthausen Hall 20 Findley Hall 351 Heritage Hall 192 Kamm Hall 7 36 Klein Hall 300 Kohler Hall 290 Lindsay-Crossman Chapel 50 Lou Higgins Center 27 Marting Hall 30 Math and Computer Science 14 Ritter Library 11 Strosacker College Union 103 TOTAL 1791 (NOTE: Residence hall numbers are based on a sample of the total rooms.) One large problem while assessing campus electrical usage was the absence of records. The school’s available records only go to 2007. This is in part due to the fact that Greg Paradis, B-W Custodial Supervisor, began keeping these records when he was hired. If the school were to keep better records they would be able to assess the change in a building’s kWh after innovations take place. We offer one possible example of a better record keeping system in Appendix D. The school should install more meters to have records of kWh usage for each building. Currently, total kWh usage per building is roughly estimated by dividing the total kWh based on the square footage of each building. This does not take into account variable lighting systems in each building. For example, better metering would allow the college to compare the energy savings of Ernsthausen Hall with other less energy efficient 37 buildings, especially other residence halls. Also, in original records it sometimes becomes difficult to differentiate between buildings in the absence of differentiated metering. We recommend the school begin programs like turning off most hallway lights during the day or even just keeping 1/3 on during the day where sufficient natural light is available. The school can also shut off lights for unused buildings during school scheduled breaks. Additionally, academic buildings do not need lights on during hours when the building is closed. It has been reported that lights are on in unused sections of buildings throughout entire breaks; this is a useless waste. Therefore, the college could install more motion sensors, especially in common areas. We recommend that the school shut down all campus computers at a certain time each night. This goal would be easily achieved with a programming script that BaldwinWallace IT could institute on computer lab computers. Computers in classrooms and computer-lab class rooms already have this option installed and will turn off after a period of inactivity. Adding this feature to the 24-hour labs would be an easy change that could help reduce electrical consumption. Long-Term Recommendations The school can also consider investing in solar panels for rooftops of some campus buildings. The school can buy these through wholesale manufacturers. Depending on the price per wattage a solar panel can range from $2.50 to $6.00 per watt. A single pallet of 20 solar panels can go for around $10,000. This would be a very large initial investment, but the money the school would save over the following years 38 could pay back this price over time9,66. The average solar panel system pays for itself within the first 10 years, depending upon system cost and utilities pricing. The college can look into making a single building solar powered to further explore this possibility. The Center for Innovation and Growth would be a good example. The CIG’s size, sunlight exposure, and flat roof make it an ideal subject for a solar panel test. The college is already moving forward with a Power Purchase Agreement for the CIG, wherein the college buys the energy from a third party investor and thus has no capital costs. An additional incentive that the government is offering is a 30% federal investment tax credit with a 5 year accelerated depreciation to help reduce the financial impact of installing solar power. These changes, while initially costly, will eventually pay for themselves and will then continue to help the college save money for years to come. If the school does not already have variable frequency drives (VFDs) installed on most appliances requiring motors, these items can help reduce energy consumption of these appliances. Variable frequency drives are additional parts to the motor that can control motor speed by controlling frequency of the electrical power supplied by the motor. VFDs initially apply a low frequency and voltage to the motor, avoiding the high current that usually occurs when motors are first turned on. An additional benefit is that the drives will increase the life of the motor as a result of the decreased stress upon it. These VFDs can be installed on motors ranging from fans, elevators, various pumps, and heating, ventilation, and air condition (HVAC) utilities. The average industrial VFD cost around $600-$1,500 and helps control electrical consumption by making the motor more efficient. One problem for VFDs is that the cable leading to the drive can become worn out from resending of electricity back up the cable; this eventually will wear out the insulation. To 39 combat this, the owner can replace the cable or even increase the size of the cable to offset the degradation of insulation. This problem aside, a variable frequency drive can reduce electrical consumption while increasing motor life63,64. Conclusion In order to achieve the goal of reducing the college’s carbon footprint by 20% by 2020, the college should begin implementing these changes. The college can immediately implement the short-term recommendations of eliminating all incandescent light bulbs and of keeping better electricity records. The other short-term recommendations are also easily attainable. The college should seriously consider the long-term recommendations presented in this report. Although they are initially more costly, installing solar panels and variable frequency drives will save the college money in the long run. The energy savings will not only reduce the college’s environmental impact but will also save the college money. 40 VIII. Commuters Commuter Group Recommendation Overview The commuter group focuses our recommendations on ways to reduce carbon emissions from travel associated with students, faculty and staff that travel to campus each day. We evaluate each recommendation with three factors. The first and most important factor is financial cost. The second is the efficiency for maximizing reductions in carbon emissions. The final factor is the ease or difficulty level of making the change, independent of financial costs. Our first recommendation is to discount carpool and high efficiency vehicle parking permits. Our second is to establish designated parking areas for students who either carpool or drive a high efficiency vehicle to college. The third recommendation is to develop and communicate information to students and other commuters on how to generate higher fuel efficiencies for vehicles and statistics relative to gas consumption. The fourth is to have a ride board for students who wish to either carpool or travel to out of town locations. The fifth proposes that the Union accept credit/debit cards. Sixth is that the college creates storage units for student bikes as an alternative to motorized vehicle transportation. Our seventh recommendation involves the college expanding the commuter lounge to provide appropriate space and technology for all commuters, which would thereby encourage commuters to remain on campus throughout the day. Carpool and High Efficiency Vehicle Parking Permit Discounts Although we don’t have evidence to support this claim, we believe that discounted student carpool and high efficiency vehicle permits might generate higher use of these 41 types of transportation. The annual cost of a parking pass at B-W is $120 for residents and $60 for commuter students16. The California Energy Commission’s Consumer Energy Center reports that the average fuel economy of U.S. passenger vehicles is 21 mpg and that of Accord, Civic, Escape and Prius hybrids is between 46 -55 mpg40. We recommend that students who either carpool or have a vehicle that exceeds a fuel efficiency standard of at least 40 MPG should receive a free parking permit. We recommend that the college include a survey with every parking permit application to determine the level of student interest in this proposal. As college students we are all aware of how expensive it is to attend college, particularly given that most students receive financial assistance. That being said, few students would pass up the opportunity to receive a free parking permit. However, this is the only cost for implementing this recommendation. Also, there will be an additional benefit in that as more students participate in carpool rides, fewer parking spots will be required for students and staff, which will then free up additional parking spaces for visitors and prospective admission applicants. The idea to include high efficiency vehicles may not generate much change in vehicle ownership since few people drive these vehicles due to higher purchase price or other vehicle preferences. But it would send a message to our students and to the larger public that B-W supports use of high efficiency vehicles. Free permits to those who carpool could result in a modest reduction in the number of vehicles on campus. The central part of the idea is that automobiles are one of the largest producers of carbon emissions and that by reducing the number of vehicles on the campus; we will therefore lower our carbon emissions. We could also differentiate the carpool / high efficiency vehicle discount permits from other parking permits by putting a green mark on the discount permits and parking spots. Currently, students must complete the 42 student parking application for every semester/ year and identify if they are a resident or commuter, their make/model of car and license number. We would suggest that the application be modified to include carpool and high efficiency vehicle permit designations. If the student applies for one of these designations, they would be required to identify the names of their passengers and who is the primary driver thereby eliminating the issuance of multiple passes. The college would police the carpooling situation in the same manner in which they police permits for handicap permits of student/faculty/staff. Designated Parking Areas Building upon that idea, we would ask the college to provide designated sections of the parking lots for carpool drivers and high efficiency vehicles. The only people allowed in these spots would be those individuals who have the free parking permits. It would not require the college to obtain any additional parking lots/spaces but rather redefine existing space which has become available as a result of students who are now carpooling. The financial cost to implement such an idea would be the cost to paint the designated spots. By designating specific spots for carpooling and high efficiency cars and other vehicles, the college would make the statement that they are committed to finding solutions to reducing our large institutional carbon footprint. If the college is concerned about spots being empty, we suggest that the spots be distributed throughout the campus. We could use the design of a handicapped parking spot as a launching pad for the design of the carpool/ high efficiency vehicle spots. For example, the college could outline the carpool permits in green and include an image of a plant in the center of the permit and paint parking places green: “Green on the Green.” Since we would use many available parking spots that many single drivers currently use on a daily basis, there may be fewer places for them to park. We view 43 this as a positive benefit, because it would encourage those drivers to carpool as a way to get more preferable parking spaces. The college could also encourage students to carpool/drive high efficiency vehicles by designating these spots at the nearest parking spaces to the buildings. This would give students an even greater incentive to carpool with fellow classmates and provoke community education. Student Information Campaign A fourth recommendation that would be low-cost, effective and easy would be to distribute information, ideally electronic and paperless, on how to generate higher fuel efficiencies for vehicles. The information could be passed out when students receive their parking pass and made available on-line. The document could include information about car idling, avoiding intra-campus driving, promoting bicycle use at school and carpooling. Miami University has also shown an interest in providing information to students on vehicle fuel efficiency. Student Ride Board A fifth recommendation is for student government to organize a “ride board” such as a paper ride board in the student union and/or an electronic ride board on the B-W intranet. Having a ride board will allow commuters to post when they are going somewhere and how many people they can take. Say a student, John, lives in Cincinnati and wants to go home for the weekend. Another student, Sue lives in Columbus and wants to go home the same weekend. Sue goes to the Union and sees the ride board sheet. She sees that John is going the same weekend. She signs her name and calls John to confirm a time and place. All Sue needs to do is pay John a small fee for him taking her home. Ohio 44 University5 uses a ride board as does Ohio State University4. They are successful and used by many students weekly. Student Payment Changes at the Union Another idea that could be inexpensive and effective would be to change payment systems on vending machines and, more importantly, the union to use credit or debit cards. Commuters do not always carry cash on their Jacket Express; most college students do not carry cash. Therefore, commuters tend to leave campus and go to someplace like Panera, Chipotle or another fast food restaurant for food and travel back to campus for class. That is wasteful and may be difficult to change. If the college allowed credit and debit cards to be used, it could reduce travel emissions. Students would not have to travel off campus for food and it would bring in more cash flow for Baldwin-Wallace. It’s not as easy for commuters to have money readily available on their Jacket Express as it is for residents because as local residents they are less likely to use a Jacket card. Putting money on Jacket Express requires cash, check or an alternative that parents do not favor, adding money to their payment for B-W. If commuters had enough money to add it to their Jacket Express, they would just use it at the vending machine or in the Union. Commuter Lounge The current commuter lounge does not have sufficient space to accommodate the number of commuters who are willing to use the facility. This reason causes some students to go elsewhere between classes because of overcrowding. The expansion of the commuter lounge would give students who have the highest carbon footprint an incentive to stay on campus between classes and other breaks throughout the day. More area is needed for commuters, they make up a substantial portion of the college population and they usually 45 live close to campus making it appealing to go home during the day. A large space somewhere on campus would cut back on the amount of trips to and from the college everyday for a number of students. Another thing that would be helpful in an updated commuter lounge would be more computers. Commuters can congregate in the Cyber-café but it only has 12 or so computers and no printer, which is a downside. Consequently, more computers would be another reason for commuters to stay on campus instead of going elsewhere. Campus Bike Barns We recommend that the college take actions to promote higher bike use on campus. This would include increased availability of bike racks. In addition, Bike Barns are fully covered and secure bike rack locations for not just commuter students but all students for that matter to place their bikes when they are not in use. Having perhaps three to four covered locations around campus would allow students to not worry about their bikes being stolen and would keep them out of the weather. Students can pick where they want to keep their bikes. The bike barns would not just be for commuters but also for residents which makes this a great project for the college to take up3. Conclusion As one can see, our group has come up with many possible recommendations for the college to reduce commuter and faculty vehicle emissions. Many are inexpensive and easy to achieve and can be implemented immediately. Some are more expensive and can be achieved in the future, but all could be great ideas for the college to implement. 46 IX. Faculty Travel and Study Abroad Our group focuses on study abroad travel and school-funded faculty travel to calculate what effect these trips have on the college’s carbon footprint. Travel related to the Conservatory and the Division of Business Administration has the highest emissions, but the political science department has the highest emissions per capita faculty. In terms of study abroad data, we calculated that trips to India involved the largest carbon emissions. In light of these discoveries we offer several recommendations for improvements that Baldwin-Wallace could adopt to reduce its overall carbon footprint and help to reach the goal of at least a 20% carbon dioxide equivalent reduction by the year 2020. Assumptions Over the course our project we found that many departments do not keep good records, which required that we make some assumptions regarding our calculations. We assumed that each line listed on the excel document the Explorations Office gave us was a separate person. We also regarded each person as taking a separate flight and that the cheapest flight was used. If the location did not have its own airport, our group selected the closest airport to the location. The websites we used to find the cheapest flights was Tripadvisor.com and to calculate the miles between these airports we used distancecalculator.globefeed.com. Once we calculated miles, we converted miles to tons of carbon dioxide using the formula: CO2 emissions= 1 mile* 1 ton CO2/2062 miles/person = 0.000485 tons of CO2. We then multiplied this number by the number of faculty and students on each trip. For some destinations, the data were too vague to convert. For example, one professor flew to the Midwest; however we had no idea where in the Midwest 47 he flew, so we ignored that trip. We also ignored two study abroad trips to Muskingum China, because such a destination does not appear to exist. Other trips required assumptions. We assumed that a flight to New Mexico went to the largest airport and from there; travelers drove to the event they were attending. For the CEA trip we assumed travelers went to Paris, France since that was the most likely trip the school went on according to options for destinations and the years of each trip. When locations for multicountry trips were in doubt we used the latest itinerary for all trips. We assumed that all group trips were led by two faculty members, which we accounted for in the measuring the carbon emissions. For faculty travel we assumed the shortest driving route and that any trip that was farther than 300 miles was flown. If the state was not given, we picked the most common location for that trip. We did not include the Gund Reconciliation trip, because we had no data on what state that was in. We also believed that if two of the same destination were listed consecutively, that they were the same professor on consecutive trips. Current Effects: For the year 2006-2007, faculty travel equated to a total of 255975.3 miles; 3151.2 miles were driven and 252824.1 miles were flown. For the year 2007-2008 faculty travel was 282155.9 miles with 9456.4 miles driven and 272699.5 miles Driving Flying Total 2006/2007 3151.2 252824.1 255975.3 2007/2008 9456.4 272699.5 282155.9 2008/2009 7571.4 285052.5 292623.9 Total 20179 810576.1 830755.1 Tons CO2: 402.89 flown. In the year 2008-2009, the total mileage was 292623.9, having driven 7571.4 and having flown 285052.5 miles. This leads 48 to a total for all three years of 20179 miles driven and 810576.1 miles flown for a total of 810576.1 miles. When converted in carbon dioxide, this equals 402.89 tons of CO2. Of the various departments, the Division of Business Administration was the highest emitter with 58.3 tons of CO2 released and the conservatory emitted 51.27 tons of CO2, making it the second highest emitter. Emissions in the political science department were the highest per person with 5.87 tons of CO2 released per person. (See graph below) 49 In terms of study abroad data, we found that travel to India releases the largest amount of CO2 with 219.45 tons of CO2 emitted for a trip there and back, most likely due to the high number of students and faculty who went on the trip. The second highest was China, emitting 188.276 tons of CO2 per round trip. (See graph below) 50 In terms of miles per semester, the Fall/Spring semester of 2008-2009 has the most miles at 1165300.885 miles flown. The total miles flown from Spring of 2006 to Fall of 2009 was 2440230.945 miles. Recommendations: After reviewing this data our group offers several recommendations to move toward our goal of 20% reduction in carbon dioxide by the year 2020. Initially BaldwinWallace needs to gather accurate information to better understand what changes can best reduce our emissions. A method of ongoing record-keeping must be initiated to document the effects of changes implemented. If the Study Abroad office and Bonds kept a record of every student/faculty member’s name, where they went, when they traveled, with flights 51 and airlines, our carbon footprint would be considerably more accurate. More accurate data collection would help B-W to better identify any trends or patterns and better understand where the majority of emissions are being released. A possible solution to reducing carbon emissions is to substitute some faculty travel with video conferencing. The Boston Consulting Group and the Climate Group estimated that IT-optimized businesses in the U.S. (which includes "smart buildings," substituting virtual meetings for business travel, and allowing employees to work remotely) could get rid of almost 500 million metric tons of greenhouse gas emissions a year and save up to $170 billion42. By 2030 the World Wildlife Fund predicts that telecommuting and virtual meetings could decrease nearly 1 billion tons of emissions annually42. Three types of video conferencing may be feasible for the college. The first is Skype, which is free and available for Smartphones and videophones62. Unfortunately, small screen size and limited conferencing capacity—only four users can use it at one time—are among drawbacks. It has a subscription fee for international calls of $12.95 per month, but only if used to call landlines or cell phones62. Cisco Telepresence at Berkeley (“ABC’s of Videoconferencing”) 52 The next alternative is Cisco Telepresence which carries an expensive initial startup cost of $600 to $3000 for hardware based desktop system8. Small-group systems cost between $3,000 and $12,000 with an appliance of $6,000 to $14,000 for a PC-based system8. Large group or boardroom systems provide the highest quality video and come with a high start-up cost of $10,000 to $300,0008. These are ISDN or IP-based, do not have a subscription fee and can accommodate multiple users at one time. Images appear at life size and the system can be fitted to a desk or office. Generally, base Cisco Telepresence systems have a 65-inch plasma screen with an embedded camera24. The final video conferencing alternative is Nefsis, an IP-based system which costs $350 a month46. Another option is to participate in carbon offset programs to make up for carbon emissions from study abroad trips and for when teleconferencing is not feasible. We have identified types of carbon offsetting programs: airline carbon offsetting (included in the ticket purchase), students and faculty initiating their own carbon offsetting programs (Some common alternatives are planting trees or renewable energy projects), or other companies that provide offsetting programs for a charge. All of these alternatives would theoretically make up for the carbon emitted through travel. In the longer term, the school could require students/faculty to calculate their total emissions and then ensure that they counteract that the entire amount by participating in one of these three offsetting programs. Faculty could also take responsibility for educating students traveling abroad. Middlebury College claims success with their Green Passport Program, a low-maintenance social networking site designed to heighten students’ ecological conscience. Participating students agree to reduce their environmental impact, respect the culture they are visiting, 53 and give back to the community17. The site also partners with other colleges, Abroad View magazine, and sustainable travel agencies to offer sustainable study abroad programs. For instance, through the Living Routes-Green Passport partnership, students from several majors including teaching, English, French, communications, business, anthropology, sustainability, and the arts may live in ecovillages and learn about sustainable community development, agriculture, indigenous cultures, and more. Students participate in carbon offsetting programs through the village and develop skills that will help them reduce the college’s footprint in the future (Living Routes teaches every student to measure and reduce emissions resulting from office activities as well as travel, commuting, electricity and paper use). Green Passport currently sends students to locales near B-W study abroad programs, such as Findhorn, Scotland and Crystal Waters, Australia; other programs are based in Senegal, Brazil, India, Mexico, and the U.S.1. The Middlebury College Study Abroad office thinks that in providing students with a linked list of resources, they are helping them to be environmentally conscious and reduce their own individual footprints53. Middlebury College has reduced the collective carbon footprint of the college as well, including a 40% reduction of net emissions of carbon due to biomass last year and the goal of becoming a carbon neutral campus19. Tips on the listed sites include warnings against harming local wildlife or attempts to take natural resources home. A number of colleges seek to reduce their footprint by providing grants for pursuing sustainability related projects or research abroad for up to $500. If students were rewarded with grants for sustainable travel, more students would be environmentally conscious while abroad and do sustainable projects 54 and research in an effort to receive these grants. The website www.350.org is an international campaign that connects students and holds events worldwide such as candlelight vigils and marches59. The number 350 comes from the upper limit of carbon dioxide in the atmosphere in parts per million. 350. org promotes reducing the carbon dioxide levels back to these limits. Its focus is a clean energy economy and is attempting to get as many members to join as possible to act as a voice for reducing carbon emissions Baldwin-Wallace’s membership would help to support carbon reduction and show that the college cares about the environment. The organization makes suggestions about planting trees, protecting rainforest, reducing waste, and investing in alternative energy solutions all of which could be taken up by faculty and students either directly or by making a donation to help these areas60. The school could also place resources for sustainable travel on its study abroad page, such as the following additional links: http://www.sustainabletravelinternational.org/documents/gi_travelchecklist.html (which provides a sustainable checklist before embarking on a trip), http://www.footprintnetwork.org/index.php (where students/faculty can determine what their carbon footprint is before traveling to determine how much of an effect they are having on the environment) , and http://www.transitionsabroad.com/listings/travel/responsible/responsible_travel_handb ook.pdf (which is an entire handbook of helpful tips that will make travel more sustainable and reduce fewer emissions). Faculty and staff could also establish a better campus carpool system for out of state road trips, where employees could arrange to travel together. A form which faculty 55 planning an upcoming trip can complete, available for all faculty to access, could help to better coordinate carpools and ensure that carbon dioxide are reduced. Avoiding certain airlines that have higher carbon emissions would also help students and faculty meet their carbon reduction goals. On a scale from 0 to 100, with 100 being the best, Continental received a 37, Southwest Airlines and Delta/Northwest both got a 40, and United and US Airways both got a 43; American Airlines received a score of 4810. All of these airlines fly out of Cleveland. The airlines received their scores based on if they measured their carbon footprint, have made efforts to reduce their carbon footprint, supported improvements on climate legislation, and disclosed their carbon reduction information to the public10. Virgin America’s Airbus A320 fleet releases 25% less CO2 than competitors and is the only airline that reports its GHG emissions on the Climate Registry55. (Airlines Sector-Brand Scores) 56 Finally, B-W could require faculty and staff members to rent hybrid cars for their trips until they have the funds to replace their own vehicles with hybrids or electric cars. This way faculty would most likely improve their gas mileage and be taking smaller cars than the B-W vans, where appropriate.* Recommendations by Cost: Better Record Keeping: In terms of prioritizing our ideas by financial cost (from cheapest to most expensive) better records would be ranked number one. It merely costs the school time and energy to save itineraries and records. Although record keeping will not reduce carbon emissions by itself, B-W will not be able to determine how much CO2 reductions or how much we are saving or spending without proper documentation. Use of Sustainable Travel Guide: Next would be the Sustainable Travel Guide. Students, staff, and professors should read it online and then make choices for their travels. Airline Preference: Students, staff, and faculty should avoid airlines that are not good in terms of CO2 offsets. This may require a higher price for better airlines, but could be considered when not substantially more expensive. Carpooling: Carpools would be after that in terms of expense, since the school will still have to pay the price of gas and tolls. However, carpools should not be very expensive to coordinate. When abroad, Saab, Lotus bioethanol are cars available for rent in Europe63. Volvo and some others provide Flexi fuel which is ethanol and petrol63. In Stockholm, Sweden biofuel is readily available at over 85 pumps. This fuel is made of non-food feedstocks and algae and releases far less carbon emissions than standard fuels, requires less servicing since the car does not get clogged with waste particles, and is cheaper. Biofuel is used by buses in Stockholm and is available throughout the UK at all Morrison’s filling stations63. There are also numerous car sharing programs throughout France. The Lille Metropole, in Lille, France, has 120 clean cars in its fleet. There is also an environmentally-friendly taxi company in Europe called Grazer63. * 57 Carbon Offset Programs: Organizing student/staff/faculty carbon offsetting programs on campus might not be very expensive. Students could plant trees in the Metroparks or could compost. Earth Day Coalition runs a collaborative Naturehood program that aims to restore native landscapes to approximately 3,000 acres of vacant land in the Cleveland area28. Baldwin-Wallace could provide student volunteers to make seed balls and plant trees—a cost-effective way of carbon offsetting, as EDC already has the materials and the funding; they simply need labor. The college could set up a regular program where travelers could “pay back” their CO2 emissions through scheduled environmental projects. This is a new concept and could potentially be very labor intensive. However, several colleges have already proven that it is possible to implement. The University of Florida worked with the Florida Forestry Association and the Environmental Defense Fund to put aside 18 acres to plant pine trees, which it will continue to protect for 10 years to offset the carbon emissions of a single football game25. The carbon emissions released from the game include all of the fan’s and team’s travel, lodging, and those associated with stadium operation. It’s continuing its carbon neutral football games by giving energy saving light bulbs, low-flow showerheads, and other carbon reducing home improvements to low income families in the area25. Further, Middlebury College gives students the option of purchasing a $36 offset from Native Energy of Vermont—offsets come from either Native American owned wind power or family farm methane digesters projects that create electricity from cow manure. By purchasing renewable energy, students increase its production, reduce greenhouse gas emissions from fossil fuel burning, and, claims Middlebury, help the college meet its CO2 reduction goals. When students return, they receive a certificate and a coupon for a pint of Ben & Jerry’s ice 58 cream22. Ohio’s family farms and local markets (such as Fresh Fork Market or Green Corps Farm) could be supported if B-W implemented a similar program with methane digesters. The airline offsets would incur some expense since the school would pay a surcharge on tickets to offset carbon emissions. For example, American Airlines allows customers to calculate their carbon footprint due to their travels and then make a donation based on their footprint to one of four offset areas, such as wind energy, forest preservation, preventing forest burning, or preserving ecosystems14. The cost for American Airlines to offset a trip from Tampa Bay to Chicago has the minimum carbon offset donation at $2.0514. Delta offers passengers the choice with their ticket purchase to donate $5.50 for domestic roundtrips and $11 for roundtrip international flights, which is used to plant trees15. Virgin Blue lets customers decide if they want to add carbon offsetting onto their ticket for a little more than a dollar58. Other company offset programs would be more expensive since students/faculty would have to donate to an organization to offset carbon emissions for their trips. One such organization is Carbonfund.org. Its prices are $5.50/metric ton of carbon39. Another organization, TerraPass, prices are $10/metric ton of carbon39. Native Energy’s prices are $13/metric ton of carbon39. Overall, Ecobusinesslinks.com states that the average carbon offset company charges about $19.50 a year to remove 3.55 tons of CO2. This cost is equivalent to $1.63 a month to offset that amount. 59 Rent Hybrids or Electric Cars: The college could tell faculty that they would only be reimbursed for rental fees if the car was a hybrid or electric vehicle. It’s cheaper than buying but requires Baldwin-Wallace to pay for a vehicle for every trip. Price depends on make, model, and year, and electric cars generally take up to 6 to 7 hours to refuel. Enterprise Rent-A-Car even allows renters to make a carbon offset donation anywhere from $1.25 to $1 million and they will match your payment29. These carbon offset payments could add up if the entire B-W faculty purchased one with each rental and Enterprise matched their donations Baldwin-Wallace could play a significant role in reducing its carbon footprint. Videoconferences: The college would purchase additional materials to set up conferencing including web cams. However, this will lead to a breakeven point financially after the trip’s transportation, lodging, and food costs are eliminated. (“Nefsis”) 60 Buy Hybrids: Finally, the most expensive option would be to purchase hybrids cars, but could recover costs through lifetime operating expense reductions. The cost of a typical hybrid, such as the Toyota Prius or the Honda Civic hybrid, is anywhere from $22,000 to $30,00048,6. This would probably be around the same cost, if not cheaper, than what the college would pay for passenger vehicle replacements anyway. Prius 2010 Honda Civic Recommendations by Effectiveness: We also ranked choices by most effective in reducing carbon emissions to least effective. Our first answer again was to keep better records. This helps the college understand fully what the current carbon footprint is and which areas the college will need to focus on in the future that are the main carbon emitters. The next most effective would 61 be videoconferencing. It removes the transportation that causes the carbon emissions both to and from the destination. Although the manufacturing of the videoconferencing equipment and the electricity used during the videoconference will still release some carbon emissions, the reduction will be tremendous. Third would be to ensure that faculty and staff rent hybrids or other high fuel-efficient vehicles, which the school could use when needed. 2010 Hybrid car costs generally range from mid-thirties to high forties65. For example, the 2010 Toyota Prius ranges from $22,800-$28,070 and the Ford Fusion Hybrid ranges from $25,666-$27,950 depending on the dealership and the car features7. Van’s prices start as low as mid-twenties to mid-thirties, which includes Fords and Chevy and Toyota65. Airline carbon offsets would be the next most effective, where the airlines will work to offset the emissions caused by the trips. Companies carbon offsets would also be very effective, but by using these instead of the airlines carbon offsets the school cannot guarantee that full trips emission will be offset depending on the donation and how the company uses the money. Regardless, it will still reduce the amount of CO2. The next most effective would be our carbon offset efforts. A group or program that everyone has to take before or after their travels to learn about carbon emissions and work towards offsetting the emissions they caused, would increase awareness and decrease carbon. It takes time for the offset to occur, since we emit faster than the trees/energy projects will work to offset the carbon. The school will also need to take into account that different types of trees also absorb different amounts of CO2. For our local trees, a single mature tree absorbs 48 lbs of carbon dioxide per year12. One acre of tree coverage can compensate for driving a car between 7,200 and 8,700 miles12. A midsized 30 mpg car that 62 drives 12,000 per year will create about 3.55 tons of CO2 per year38. A potential problem for effectiveness depends on if the tree survives and grows to maturity61. Next would be airline preferences. It may not be “good”, but it is “less bad” than traveling on airplanes that are not fuel-efficient. Carpooling would be after that, since it still releases carbon emissions for the trip, but depending on how many people travel together, can have a substantial impact. If two people travel together total carbon emissions would be around half of what they would have been if each traveled separately. The least effective would be to have the students and faculty only use the Sustainable Travel Guide, because it’s up to the reader if they chose to enact the advice from the guide. Yet, it can be very effective if all of the recommendations are taken. Recommendations by Difficulty Disregarding financial cost, the recommendations ranked from easiest to hardest to achieve would still have the list start with record keeping. It would be helpful if B-W kept itineraries. If they wanted to be more accurate, they could fill out the spreadsheet that our group is making to help with the records for study abroad and faculty travel (See Attachment). The Sustainable Travel Guide would be relatively easy as well, since students and faculty just have to read the suggestions and make small changes in their lives. Airline preferences would be next. B-W travelers simply need to avoid companies that have planes that release a lot of carbon. Our carbon offsets should not be too difficult to implement, because the school would just have to add an additional program to B-W in which B-W students and faculty could plant trees, create a garden, or walk more instead of driving to counter their emissions. Airline carbon offsets would be slightly more difficult but still relatively easy, because students and faculty need to specify that they want carbon offsets 63 added onto their ticket and pay a slightly higher price. Other companies carbon offsetting would mean that students/faculty would have to contact an organization that would counteract their carbon emissions from their travels and write a check. Luckily, there are several organizations that students/faculty can use to offset emissions. Renting hybrids would be about as easy, but students/faculty would need to contact a car rental and specify that they need a hybrid and provide the dates of the trip. Carpooling would be more difficult because faculty would need to be in touch with other professors who are traveling around the same time to similar areas. Finding someone to travel with could be made easier by having an online calendar of all faculty trips so when a faculty member is planning a trip they could look to see if anyone else is going to the same place around the same time. B-W could also arrange a campus website to help coordinate these trips. Following this in terms of difficulty would be video conferencing. Organizing the meetings by video could be hard to arrange because it would be hard to coordinate people’s schedules and find a spot to hold the video conferencing from. It would require the people that the meeting is with to have videoconferencing abilities on their end also. It may be difficult to find an appropriate place for web cam meetings and set up the system at B-W. The most difficult solution for Baldwin-Wallace to implement is to purchase hybrids. It would take some time and effort for B-W to raise funds and shop around for the most fuel-efficient vehicles. Implementation Schedule Overall, several changes need to be made now to start working to reduce carbon emissions by 20% by 2020. This year the school could start keeping better records and saving itinerates. It could work on a carbon offset program to get started for fall semester 64 or use one of the other offset programs in the meantime until ours could is up and running. Until the school acquires the funds to purchase hybrid or other higher fuel-efficiency vehicles, faculty and members could be required to rent only hybrids or carpool if not already doing so for all of their travel nearby. For travel over 300 miles or for study abroad trips, only more sustainable airlines should have trips booked on them. Students and faculty who are traveling should have to read the sustainable travel tips off the websites before embarking on their trips. Finally, the school should start looking into web cam possibilities for the future. The current savings in the other areas will hopefully help to fund the web cam purchases. Baldwin-Wallace can definitely reach this reduction goal, but we will need to start acting now. 65 X. Conclusion With this carbon footprint analysis, Baldwin-Wallace College stands in the position to further its leadership in sustainability It now has the opportunity to make a firm institutional commitment to join the ranks of leading academic, corporate, municipal, and nonprofit institutions in our country and abroad to set and achieve carbon emission reduction goals that are essential for the future of humanity and the planet. In order to attain 20% carbon emission reductions by 2020, we must realize that, throughout this report, our groups reiterate the important need for comprehensive, on-going, thorough record keeping of all college activities that result in CO2 emissions. Secondly, we recommend that individuals be designated to continuously update this analysis on an annual basis and that this analysis become a public document available internally and externally. We highlight a variety of recommendations, all of which are easy and low to no cost. Among Scope One groups, the Vehicle Pool recommends a no idling policy; the Buildings & Grounds group recommends mowing grass to a lower height and allowing it to grow taller. Refrigerants recommends turning off lights, opening doors and windows, and increasing thermostat control set points 1-2 degrees during warmer seasons. Our Scope Two group, electricity, recommends shutting down computers after lower inactivity times and keeping fewer lights on. Within Scope Three, the Commuter group recommends a ride board, and Study Abroad and Faculty Travel group recommends the Sustainable Travel Guide, preferences in airlines, an online calendar of faculty trips, and setting up a Skype account for conferences. 66 Other recommendations can be separated into two categories: the Replacement category and the Forward Action category. Much of what was recommended were potential replacements to what currently exists. For instance, the current refrigerant being used will be phased out, so we recommend replacing it with the most sustainable (and cheapest) alternative. Eventually, B-W will have to replace what is currently being used and this report gives sustainable options—from cars to insulation to windows to paint to light bulbs. The second category is the Forward Action category, where B-W would take the initiative to install new technologies, such as green roofs or a combined heating and power system. The recommendations in these categories, understandably, can be implemented in steps: compact fluorescent and LED bulbs now, hybrids later. Eliminating 20% of our carbon emissions by 2020 is an easily achievable goal by the college. Shutting down computers or turning off lights quickly creates huge cost savings and emissions reductions. B-W has made good incremental, non-systemic improvements to be more sustainable. This Carbon Footprint Analysis is a tribute to our ongoing efforts, and the project shows that this institution cares about sustainability. Knowledge, as always, is power. Now B-W has the power to take our increment al efforts to a much higher and more effective level, benefitting the college, its students, faculty, staff, future generations of alumni, and not least, the future of humanity and our planet. 67 XI.

NH E-mail Dr. Thomas responded that the units may only be serviced every few months or so that Karen Hart in B&G may be able to assist us further. KR E-mail Dr. Thomas forwarded a response from R. Scott Thomas, (title), for Sherwin-Williams describing the process of adding R-22 to a cooling unit, the recovery process and determining escaped emissions. He noted that if we do not have good maintenance records - we need to estimate the amount of emissions loss by the square footage of the building. *Dr. Thomas to find out of B&G services all units. KR E-mail Nate contacted R.Scott Thomas, Director of Environmental Affairs for Sherwin-Williams to inquire about: how is refrigerant removed, how does the square footage of a building affect our calculations. NH E-mail R. Scott Thomas responded with information about determining emission factors if you have good maintenance records (add up amount of refrigerant use-recovery X emission factor - e.g. 10% loss a year). No good maintenance records (that is us) need to estimate the amount of refrigerant loss per square footage of building. He also attached to the e-mail EPA document "Direct HFC and PFC Emissions from Use of Refrigeration and Air Conditioning Equipment".

Was told by Karen Hart that she only keeps gasoline records. Informed that we should contact Larry Seitz lseitz@bw.edu - he is HVAC technician. She suggested e-mailing him because he is in and out alot. Nate Hauff nhauff@mail.bw.edu 740.277.9777 E-mail Received e-mail from Nate Hauff, Team C co-worker, that he was effectively dropping the course. KR E-mail Per Karen Hart's information, I e-mailed Larry Seitz to introduce myself and to ask where I can get a list of all the buildings on campus that have air conditioning units. KR Phone Left Larry a message following up on my e-mail that I sent to him 2/5/10 because to date, I haven't heard back yet. Told him that I will need to provide some information to Dr. Krueger and Dr. Thomas by next Tuesday. KR E-mail Left message for Karen Hart that I have not gotten a response from Larry Seitz and if there are any other points of contact that I could use to obtain information on the air conditioning units on campus, that would be helpful. Also informed her that I need to get something to Dr. Krueger and Dr. Thomas by Tuesday 2/16/10. KR Phone Spoke to Larry - he provided info as far as A/C units on campus, geothermal, information about Smith & Oby - only come out on breaks and when there are problems.

Also, some additional information about types of propellant and their GWP (global warming potentials). (See attached) KR Person In class, I discussed with Dr. Thomas the records that I was able to collect from Larry Seitz. She asked me to e-mail the spreadsheet information that I compiled regarding the A/C buildings on campus. She was meeting with Larry Seitz 2/17/10 @ 9:00 and she would ask him for additional information. KR E-mail E-mailed Sabina list of questions for Larry Seitz with A/C records. The questions include: which Beech Street address has A/C (there are two), I have maintenance records for Loomis & MCS, and Dietch but he didn't mention those units has having A/C, is R-22 used in all units, what are the charges of the units, and what is the lbs. of propellant being used? Also forwarded to her R Scott Thomas's e-mail received on 2/15/10 per her request. KR Person Per Sabina, she was unable to meet with Larry Seitz this morning. Meeting was cancelled - no new updates. KR E-mail Sent an e-mail to Region 5 (Cleveland) EPA to ask if there is a staff member that would be able to answer questions about R-22. KR E-mail Received e-mail correspondence back from EPA of contact name Paul Novak to direct question to about R-22. KR E-mail Sent correspondence to Paul to verify if R-22 in fact has not GWP and if it is being phased out in the future KR E-mail Sent reply thanking R Scott Thomas for example spreadsheet for refrigerant calculations and notified him of updates to this point.

Also, R22 is used in the majority of campus units but not all. 410 A is used in some units - mainly newer units. The units vary from 2.5-50 ton units that could use anywhere from 3 lbs-100 lbs of coolant. Overall, we still don't have specifics. KR E-mail Sent response to Dr. Thomas thanking her for information and provided her an update on the EPA's response about R-22. Need to research 410 A next. KR KR Sabina Thomas sfthomas@bw.edu 440.826.2267 E-mail Received e-mail from Dr. Thomas that R-22 is being phased out due to the ozone depleting capabilities. She also sent link that R Scott Thomas originally sent from the EPA regarding Refrigeration units. Paul Novak Novak.Paul@epamail.epa.gov 440.250.1714 E-mail Sent e-mail to Paul to ask about 410a KR E-mail Dr. Thomas met with R Scott Thomas from Sherwin Williams, Barry Cupp and Sarah Jones on Wednesay 2/24/10 and compiled a document of information that was attached to the e-mail. The document included a spreadsheet conversion example of approximate loss of propellant for when you don't have specific enough information. This spreadsheet is divided into: Refrigerant type, Building name, Square footage of 2 building, propellant/1,000 ft and the amount of propellant needed. Also, there are notes to assume the worst case scenario (round UP the amt. of propellant with higher GWP). The second spreadsheet was an example of recommendations to give B&G to collect information going forward and contained the following criteria: Building name, square footage, A/C Unit (type or #), Type of refrigerant used, replacement/leakage values, date of 2 service (and company name), propellant/1,000ft and amount of propellant needed. (See attached). (In addition to that, I think records should be kept of all refrigerator units - pop machines, refrigerators in admin. buildings, etc).

KR E-mail Sent e-mail to Dr. Thomas confirming that I received e-mail from her on 2/26 and that I would spend the following week (spring break) reviewing material that I had thus far. KR E-mail Received e-mail from Dr. Thomas to submit calculation results to her for carbon footprint project as soon as possible. Reminder that the class will be working on project again week of 3/22/10. KR E-mail Sent e-mail to Dr. Thomas stating that I reviewed all material and there are still gaps in data to calculate accurate emissions. I have square footage of buildings and a good list of buildings with A/C. I do not have: type of A/C unit in each building, amount of propellant used in those units or the type of propellant used R-22 or 410a. I asked her if I should use worst case scenario and use the largest possible A/C unit (70 tons) and largest amount of propellant (100 lbs.) and the largest GWP propellant 410a or make an attempt to go back to Larry Seitz to get more info.? KR E-mail Dr. Thomas' response said to go back to Larry Seitz to try to find out at least what percentage of buildings with A/C use R-22 vs. R-410a. Then, use lbs of propellant X square feet and assume 10% leakage. KR E-mail Sent e-mail to Dr. Thomas that I would attempt to contact Larry Seitz for more info on units and use of propellant R-410a and R-22 KR E-mail Sent Paul Novak an e-mail to find out if A/C propellant emissions are required to be reported to the EPA. If so, what industries, how often? KR Phone Left message with Bill Hawley to give to Larry Seitz to contact me about R-22 and R-410a. Larry was unavailable at the moment.

Per Paul, I should review the website www.epa.gov, and type in EPCRA for more information. KR Phone Per Larry Seitz, only a handful of new buildings will be 410a. Currently, only the CIG is using 410a and the rest of campus is R-22. But, in the future, McKelvey, Wilker, Life & Science will be using 410a when they are finished. Ernhausten is R-22 also.Also confirmed that 21 Beech or Zeve's Hall has A/C and that he is unsure of any residential housing that may have A/C unless they call him to inform him of a problem. KR E-mail Sent e-mail to R. Scott Thomas regarding final questions for estimate calculations. Asked him if I should assume worst case scenario for unit size and propellant used (70 ton unit with 100lb propellant). And asked him if R-22 is same as HCFC-22 on the the GWP website and how he got the GWP for 410a of 3800 - is it the same as H-134a? KR E-mail Barry Cupp, Corporate Environmental Affairs Project Manager, responded with correct data for 410a and R-22 GWP and suggested that we use the middle range if we don't know the unit size and propellant. Also suggested that we use 134a for the propellant because eventually, after R-22 is phased out, 134a will replace everything in 10 years. KR 3/23/10 2:20 PM Sabina Thomas sfthomas@bw.edu 440.826.2268 In person Resolved with Dr. Thomas which propellant to use per Sherwin Williams suggestion H134. Also, determined how to calculate lbs. of propellant used per spreadsheet. Square footage X propellant/ft2X10% loss for year. Cannot determine how to get CO2 equivalent. She will get back to me on that part. 3/24/10 3:13 PM Sabina Thomas sfthomas@bw.edu 440.826.2268 E-mail Dr. Thomas sent correspondence clarifying where emission factor is on climate calculator spreadsheet. 106 KR 3/26/10 3/26/10 3/26/10 3/26/10 3/31/10 4/5/10 4/5/10 4/6/10 3:00 AM Bill Kerbusch 3:26 PM Kristi Reklinski 4:13 PM Kristi Reklinski 8:03:00; 8:23 PM Sabina Thomas 4:19 PM Kristi Reklinski 4:59 PM Kristi Reklinski 10:45 PM Sabina Thomas 12:33 PM Kristi Reklinski bkerbusc@bw.edu kreklins@bw.edu kreklins@bw.edu sfthomas@bw.edu kreklins@bw.edu kreklins@bw.edu sfthomas@bw.edu kreklins@bw.edu 440.826.2233 440.826.2102 440.826.2102 440.826.2268 440.826.2102 440.826.2102 440.826.2102 440.826.2102 107 In person Asked Bill Kerbusch, Director of B&G, about geothermal and refrigerant use. Less refrigerant used on geothermal because it's only used in the compressor not whole system. Compressor kicks on to meet in the middle to reach thermostat temperature (difference between heat pump water and thermostat temperature) KR E-mail Sent Dr. Thomas information that I found that the conversion for tons of coolant per square footage is 1 ton per 600 square feet. KR E-mail Sent Dr. Thomas an example calculation for Bonds of amount of propellant use and percentage loss for her to review to make sure that I am on right track. KR E-mail Dr. Thomas responded to use 1 ton per 500 feet per Sherwin-Williams recommendations. Also sent website with information: http://www.inspectapedia.com/aircond/aircond03.htm. She also confirmed that the sample calculation looks accurate. KR E-mail Sent e-mail to Dr. Thomas that after further review the calculations do not look correct. Sherwin-Williams got 2,200 lbs loss with 500,000 square foot area and my example calculation had 20,000 lbs loss with 65,000 feet. Decided to utilize R Scott Thomas calculation with conversion factors and CO2 equivalent that will correctly calculation emissions. KR E-mail Sent to Dr. Thomas calcualtions for R-22, if supplemented with 410a, and H-134a for a year and three years worth. KR E-mail Email received from Dr. Thomas questioning my notes about calculating 2 years worth of emissions for Life & Science, Wilker and ?. KR E-mail Sent response to Dr. Thomas that I need to remove that note - keeping all three years worth of calcs in for those buildings to accommodate lack of calcs for CIG and Ernhausen that are geothermal and use less refrigerant. Can't calculate according to square footage because geothermal works differently. KR 4/16/10 10:15 PM Bill Kerbusch bkerbusc@bw.edu 440.826.2233 108 In person Met briefly with Bill Kerbusch, Director of Buildings & Grounds, to review some of my recommendations with him. College is already using durlamp roofing which is white on several buildings. Planting trees next to buildings to shade is a no go because of roots getting into water systems and cracking foundations and sidewalks. Geothermal cost and savings compared to A/C conventional units is $500,000. Test for thermostat controls was Bonds and Marting. President has signed off on this for all administrative and academic buildlings (68 in winter, 76 in summer). Residential halls cannot be included because children live there.
