This document first summarizes the greenhouse gas (GHG) emissions and related data; and secondly, provides the details of the proposed “climate action plan” required to meet the ACUPCC and University Challenge goals. The ACUPCC1 and PlaNYC Mayoral University Challenge2 require GHG inventory reporting of various metrics across several years, using multiple reporting and analysis tools. NYU-Poly signed on to the ACUPCC program, which aims to address global climate challenges, and which consists of a network of higher education institutions that have committed to eliminating net greenhouse gas emission from campus operations. ACUPCC strives to promote research and educational efforts with regard to climate change. This program provides a framework that colleges and universities may use to develop comprehensive plans in pursuit of climate neutrality. NYU-Poly has used the 2008–2009 fiscal year baseline to report its GHG emissions using the Clean Air-Cool Planet Campus Carbon Calculator (V6.4). This has been posted to the ACUPCC online reporting system. The 2006–2007 fiscal year GHG inventory was prepared for the PlaNYC University Challenge. The GHG emissions reported here are based on the PlaNYC Greenhouse Gas Emissions calculator, and only report GHG emissions from building energy use and operations. The University Challenge launched in 2007 and aims to reduce GHG emissions by 30% in a 10-year timeline. This Climate Action Plan bases its emission reduction measures off of the 2008-2009 inventory to be consistent with the ACUPCC and includes a more comprehensive reporting of scope 1, 2 and 3 emissions totaling 14,169 CO2e. NYU-Poly faces some unique challenges and opportunities with regard to climate change and achieving climate neutrality. The student enrollment is expected to increase, and Poly is actively recruiting new faculty. The quality and vintage of the buildings on campus drives the implementation of much needed capital improvement projects. Some of these renovations have made it necessary to temporarily lease space in order to continue normal operations. As a leading science and technology institution, Poly has plans to expand and upgrade its laboratories, which has the potential to increase energy consumption. While these factors amount collectively to a potential obstacle to achieving climate neutrality, they also present a valuable opportunity to make design decisions that will optimize Poly’s energy performance. In an effort to better understand the institution’s sources of GHG emissions, Poly is committed to implementing strategic measures that will not only eliminate emissions, but also model best practices that will benefit the community at large. 1 http://www.presidentsclimatecommitment.org/ 2 http://www.nyc.gov/html/gbee/html/home/home.shtml CTG Energetics, Inc. 2 NYU-Poly Sustainability & Climate Action Plan 1. INTRODUCTION Background on NYU-Poly NYU-Poly is ranked fourth in the nation among engineering colleges. At present, NYU-Poly’s undergraduate enrollment is 1,768, representing 26 states plus the District of Columbia and 34 countries. In the spring of 2009, iNYU‐Poly embarked upon its i2e Campus Transformation, facilitated by a $50 million loan from New York University. Approximately $12 million has been earmarked for new faculty hires; the remainder was allocated to faculty labs; infrastructure upgrades, including information technology, classrooms, and asset improvements. This campus transformation demonstrates the administration’s belief that physical facilities play a critical role in helping NYU‐Poly reach its academic objectives by attracting top‐level faculty, high‐ achieving students and ultimately establishing the institution as a world‐class center of applied science, technology and engineering. The campus facilities transformation, initiated in May 2009, developed a Capital Improvement Plan for the campus and involved community collaboration through several town hall meetings. Six driving principles guided the establishment of a successful Capital Improvement Plan: i2e, Green, Engagement Process, Transparent Process, Strategic Planning, and Exemplary Design. A strong governance system established early in the process welcomed input from the entire NYU‐Poly community and promoted transparency and collaboration. Several committees composed of faculty, students, and administration were engaged in the process and included: Steering, Space Planning, Special Projects, Laboratory, and Academic Spaces. A multi‐disciplinary team of expert engineering and architecture firms conducted a comprehensive assessment of the NYU‐Poly facilities. Concluded in June 2010, the assessment highlighted several challenges and opportunities, and revealed that existing campus facilities will require a significant investment—more than $250 million—to make the needed capital improvements to bring buildings in compliance with current building standards. The Capital Improvement Plan was charged with addressing these needs over a 10-year period. Importance of Understanding Climate Change Climate change is a significant and lasting alteration in the statistical distribution of weather patterns over periods ranging from decades to millions of years. Climate change can be thought of as a change in average weather conditions or the distribution of events around that average (e.g., more or fewer extreme weather events). Effects may be limited to a specific region or occur across the entire planet. According to the Pew Center on Global Climate Change, “This warming, along with the associated changes in precipitation, drought, heat waves, and sea-level rise, will cause severe damage to society and ecosystems.”3 Global warming is the observed increase in average temperature of the Earth’s surface and atmosphere. One identified cause of global warming is an increase of greenhouse gases (GHGs) in the atmosphere. GHGs are those compounds in the Earth’s atmosphere that play a critical role in determining its surface temperature. Specifically, GHGs allow high-frequency solar radiation to enter the Earth’s atmosphere, but trap the lowfrequency, long-wave energy which is radiated back from the Earth to space, resulting in a warming of the atmosphere. The earthward movement of this long-wave radiation is known as the “greenhouse effect.” Studies indicate that the effects of global climate change include rising surface temperatures, loss of snow pack, sea level rise, more extreme heat days per year, and more drought years. Understanding of the fundamental processes responsible for global climate change has improved over the past decade, and 3 http://www.pewclimate.org/science-impacts/about CTG Energetics, Inc. 3 NYU-Poly Sustainability & Climate Action Plan predictive capabilities are advancing. However, scientific uncertainties remain surrounding the response of the Earth’s climate system to combinations of changes, particularly at regional and local scales. Consequently, the scientific community has developed scenarios reflecting current understanding about the plausible range of variation in social and economic responses and considered them with multiple independent computer simulation models. The result is a range of potential future conditions, given differences in social and economic conditions, and the response of the Earth’s climate system to anthropogenic perturbations, such as continued emissions of heat-trapping greenhouse gases. The six most globally important GHGs are carbon dioxide (CO 2), methane (CH4), nitrous oxide (N2O), sulfur hexafluoride (SF6), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs). Carbon dioxide is the most abundant GHG, and it is conventionally used as a benchmark of the relative heat trapping potential of atmospheric pollutants. These gases have different potentials for trapping heat in the atmosphere; each gas has its own global warming potential (GWP). For example, one pound of methane has 21 times more heat capturing potential than one pound of carbon dioxide, nitrous oxide has 310 times more heat capturing potential than one pound of carbon dioxide, and sulfur hexafluoride has 3,200 times more heat capturing potential than one pound of carbon dioxide. When dealing with an array of emissions, the gases are converted to their carbon dioxide equivalents for comparison purposes and expressed in units of metric tons of carbon dioxide equivalent (CO2e) units, or MtCO2e. A metric ton is approximately 2,205 lbs. When it comes to climate change, environmental justice presents a fundamental moral and political challenge that adversely impacts every corner of the globe. For example, in New York City, temperatures are projected to increase by up to 8⁰F in winter and 7⁰F in summer. This radical alteration will damage local agricultural and economies, leading to increased concentrations of ozone pollution at ground-level; harmful health conditions such as respiratory illness; and sea-level rise, which may lead to flooding. Some scientists warn that parts of Manhattan and surrounding boroughs may be under water by the end of the century.4 Energy use in buildings accounts for 75% of New York City’s greenhouse gas emissions, and it is anticipated that 80% of these buildings will still exist 40 years from today. At NYU-Poly, taking responsibility for one’s greenhouse gas emissions footprint is a priority. While the campus as a whole is faced with unique building performance challenges, NYU-Poly is committed to enhancing the overall building performance in an environmentally sustainable way. The institution is making strategic decisions to mindfully renovate, improve and build campus facilities. The cornerstone of the institution’s climate action plan is its recognition that energy efficiency improvement is a critical path toward building improvements and meeting Poly’s climate commitments is. Beyond the physical structures, NYUPoly is an institution for students looking to advance in science and technology. The curriculum caters to students interested in sustainability and is developed out of intense research efforts. NYU-Poly has historically hosted community events aimed at elevating awareness and prominence of environmental stewardship, and will continue building community support to further its goal of climate neutrality. As an institution built on leadership, Poly strives to model best practices that will benefit the community at large. Sustainability at NYU-Poly Located in the heart of Brooklyn, NYU-Poly is strategically positioned to embrace a host of opportunities and challenges when it comes to long-term campus sustainability. The dense campus community has the advantage of being easily accessible by a host of public transportation options, thereby reducing the need to rely on personal vehicles. The campus is undergoing a robust facility transformation, described above and known as i2e, is clearly communicated on the University’s website: http://www.poly.edu/campustransformation. This campus transformation demonstrates the administration’s belief that physical facilities play a critical role in helping NYU‐Poly reach its academic objectives by attracting top‐level faculty, high‐ 4 http://www.climatechoices.org/assets/documents/climatechoices/confronting-climate-change-in-the-u-s-northeast.pdf CTG Energetics, Inc. 4 NYU-Poly Sustainability & Climate Action Plan achieving students and ultimately establishing the institution as a world‐class center of applied science, technology and engineering. NYU-Poly’s campus is undergoing significant changes, including minor renovations, more major redevelopment of the administration building and other buildings, and the campus expansion in a neighboring high-rise building. These changes are being implemented with sustainability design and construction practices in mind, thereby enabling NYU-Poly physical buildings to also serve as a learning resource for students. In 2004, NYU-Poly established the Brooklyn Enterprise on Science and Technology (BEST), its first business incubator aimed at providing resources to start-up and spin-off companies, at its downtown Brooklyn campus.5 In 2009, NYU-Poly established a second incubator, Varick Street, in Manhattan as part of Mayor Bloomberg’s Five Borough Economic Opportunity Plan. These incubators are an integral component of NYUPoly’s i2e philosophy (invention, innovation, and entrepreneurship). NYU-Poly is proud to be involved with the New York City Accelerator for a Clean and Renewable Economy (NYC ACRE), an incubator focused on supporting clean technology oriented companies to model environmental sustainability and smart growth. Poly is the recipient of a four-year grant offered by the New York State Energy and Research Development Authority (NYSERDA) and aimed at fostering an ecosystem of entrepreneurs, international companies, and innovative local businesses that are providing solutions to climate and energy issues while supporting the clean tech/renewable energy sector and creating jobs in New York City. NYC ACRE provides resources for companies who need strategic guidance and business assistance with a focus on alternative energy and clean technology, or a product or service offering that has a clear linkage to a more sustainable urban environment. The goal of each of Poly’s incubators is to provide the guidance, expertise, and resources that organizations need to grow into successful ventures that bring economic growth to New York City. NYU-Poly has an active Office of Residence Life, which began an initiative with the Facilities Department to pilot R.E.D.O. (Reduction, Education, Do Research and Outreach). Daniel Aniello, Director of Residence Life and member of Poly’s Sustainable Practices Committee, created R.E.D.O. as a way “to develop Residence Life into a green community and to use its success as an example of sustainability for the rest of the campus.” The efforts of R.E.D.O. have created programming to motivate and educate students about the benefits of being more environmentally conscious. For example, R.E.D.O. replaced hallway flyers with small dry-erase boards and also combined recycled materials and large dry-erase boards to create a centralized, paperless bulletin board to promote events and share environmental Facts of the Day. Paper consumption by administrators has also been reduced significantly. By moving forms online, paper waste generated by weekly maintenance requests has been reduced by 80%; waste generated by health and safety forms has dropped 88%; and waste associated with rounds reports has been 100% eliminated. New policies in the Office of Residence Life require staff to turn the lights off when they leave the office, shutdown or hibernate computers when the office is closed, use natural light whenever possible to illuminate the office, and unplug electronic devices when they’re not in use. NYU-Poly also offers a host of courses and degrees in the field of environmental sustainability such as: Clean Energy Leadership, Urban Systems Engineering & Management, Psychology of Sustainability, Sustainable Cities, and Sustainable Urban Environments. The Sustainability Task Force established by NYU-Poly includes the Vice President of Finance & Business Affairs, other administrators, committed professors, and students. Several committees composed of faculty, staff members, students, and administration have been engaged in the process and included: Steering, Space Planning, Special Projects, Laboratory, and Academic Spaces. 5 http://www.poly.edu/business/incubators CTG Energetics, Inc. 5 NYU-Poly Sustainability & Climate Action Plan 2. NYU-POLY’S COMMITMENT TO CLIMATE CHANGE MITIGATION In 2009, NYU-Poly engaged in a formal process to better understand the physical performance of the campus buildings and the GHG footprint of campus-wide operations. Committees contributing to this effort were comprised of faculty, staff, students, and administration. A multi‐disciplinary team of expert engineering and architecture firms conducted a comprehensive assessment of the NYU‐Poly facilities, which was concluded in June 2010. The assessment highlighted several of challenges and opportunities. Extensive improvements to certain campus buildings were identified as necessary—including wholesale mechanical system replacements, critical electrical improvements, window replacements, fire safety system upgrades, roof replacement, and more—in order to meet minimum building standards. NYU-Poly wanted to undergo the campus transformation in a sustainable manner, consistent with green building principles that would reap long-term benefits. The University made two commitments in order to formally set sustainability as a goal. These commitments are outlined below: American College & University Presidents’ Climate Commitment (ACUPCC) NYU-Poly has engaged in the American Colleges & University’s President’s Climate Commitment (ACUPCC), which involves making an institutional commitment to eliminate net greenhouse gas emissions by the year 2030. The program encourages signatories to go beyond the strategic measures of physical improvements and offsets by incorporating sustainability in the classroom and broader community. NYU-Poly has embraced this commitment primarily through the sustainable i2e campus transformation, coupled with incorporating sustainability into the academic curriculum that will instill best practices in its students, yielding benefits that will be realized for years to come. The ACUPCC commitment entails the following actions: 1. Initiate the development of a comprehensive plan to achieve climate neutrality as soon as possible. a. Within two months of signing this document, create institutional structures to guide the development and implementation of the plan. b. Within one year of signing this document, complete a comprehensive inventory of all greenhouse gas emissions (including emissions from electricity, heating, commuting, and air travel) and update the inventory every other year thereafter. c. Within two years of signing this document, develop an institutional action plan for becoming climate neutral. 2. Initiate two or more interim actions to reduce greenhouse gases while the more comprehensive plan is being developed. NYU-Poly has already initiated the following three interim actions: a. Establish a policy that all new campus construction, where feasible, will be built to at least the U.S. Green Building Council's LEED Silver standard or equivalent. The new construction of the Science & Engineering Building will be built to at least LEED Silver standards. b. Adopt an energy-efficient appliance purchasing policy requiring purchase of ENERGY STAR certified products in all areas for which such ratings exist. All emissions reduction measures in this Climate Action Plan include the purchasing of ENERGY STAR qualified equipment where applicable. c. Encourage the use of and provide access to public transportation for all faculty, staff, students, and visitors at NYU-Poly. The vast majority of faculty and staff currently commute to campus via public transportation. CTG Energetics, Inc. 6 NYU-Poly Sustainability & Climate Action Plan In addition, NYU-Poly has completed extensive ASHRAE Level II Energy Audits for all campus buildings.6 These energy audits were able to identify and quantify specific energy improvements in each of the campus buildings, which, when implemented, will result in significant energy and savings and GHG reductions. 3. Make the action plan, inventory, and periodic progress reports publicly available. In an effort to best understand the campus-wide emissions sources, NYU-Poly conducted a comprehensive greenhouse gas emissions inventory for all operations. This inventory lays the foundation for the Climate Action Plan in order to benchmark future progress in emissions reduction. The inventory reveals the largest sources of emissions, which is useful for focusing mitigation efforts. For example, the majority of Scope 1 and 2 emissions are directly attributed to the operation of campus buildings, while findings reflected Scope 3 emissions are dominated by Student Air Travel Home at the end of each semester. This inventory used in conjunction with detailed analytics has created a roadmap to plan for future mitigation of emissions. NYU-Poly has developed three realistic scenarios in working toward climate neutrality. 2030 is the established target date to achieve the ambitious goal when the University will produce net-zero emissions, meaning that NYU-Poly will operate without emitting greenhouse gases through a variety of well-planned mitigation measures. NYU-Poly is determined to achieve optimal greenhouse gas emissions reductions in a way that is technically and fiscally feasible, while staying true to its academic vision. In addition to limiting operational environmental impact, the ACUPCC also commits NYU-Poly to incorporating climate neutrality and sustainability into its overall educational experience, research agenda, and community outreach efforts. 2.1.1. NYU-Poly’s plans to make sustainability a part of the curriculum NYU-Poly is an institution for students looking to advance in science and technology. Academic offerings at Poly that address climate change include, but are not limited to, the following courses. Course CE3223: Environmental Engineering I. Each semester, students in this course learn how a wide range of activities—including the burning of fossil fuels, changes in land use, and cement production— contribute to carbon emissions. Students assess waste source reduction, recycling, the use of renewable energies, and other environmental conservation measures with significant potential to reduce carbon emissions. Future emission scenarios are also discussed in terms of environmental protection and economic development. Course CE7753: Urban Environmental Systems Management. Students receive an introduction to General Circulation Models (GCMs) to make an assessment of future emissions/climate change scenarios. Environmental sustainability, as it is relates to carbon emissions, are discussed in terms of growth in population, affluence, GDP, and energy consumption. NYU-Poly is part of New York's Accelerator for a Clean and Renewable Economy (ACRE), a “clean-tech” incubator with a New York State Energy Research and Development Authority (NYSERDA) grant to seed fund qualifying startup companies. NYU-Poly is offering a Cleantech Execs program that offers 10 intensive, daylong work sessions and seminars featuring clean-tech industry practices, operational lessons, site visits, and participation in real-world projects. Senior faculty members from NYU-Poly and New York University will be joined by lecturers from industry and finance experts. The curriculum was developed out of an intensive research and original curriculum effort. 6 ASHRAE Level II audits were completed by Steve Winters & Associates in September 2010 CTG Energetics, Inc. 7 NYU-Poly Sustainability & Climate Action Plan 2.1.2. NYU-Poly’s plans to expand research efforts toward the achievement of climate neutrality The basic, applied, and translational research carried out by NYU-Poly’s faculty has several focus areas that directly contribute to progress towards carbon neutrality, green chemistry, and the generation of green and renewable energy sources, all of which are key components for achieving the goal of climate neutrality. These efforts include those of individual researchers, institutional research initiatives involving multi-disciplinary groups of faculty, as well as targeted technology transfer and commercialization routes of faculty-generated intellectual property in areas that support climate neutrality. For instance, Professor Richard Gross, a chemistry professor and winner of the 2003 Presidential Green Chemistry Award, conducts research into using biocatalyst and bioprocessing of macromolecules to produce commodity chemicals from non-petroleum-based feedstock. Professor Ted Rappaport (in the Electrical Engineering Dept.) is developing wireless technologies with applications for smart grids, Microgrids, and real-time building performance monitoring. Professor Francisco De Leon, also a faculty member in Electrical Engineering, is developing a new distribution toroidal transformer that is smaller, lighter, more efficient, and free of chemicals for cooling, and has reduced noise and RF emissions. These areas of focus will be strengthened further with the launch of NYU’s Center for Urban Science & Progress (CUSP), the University’s flagship applied science institute that will address global urban challenges, including climate challenges, with cutting-edge, data-driven technologies designed to leverage cities’ density, scale, and dynamism. NYU-Poly is already a leader in supporting the development of cleantech applications. Most of the tenant companies at NYU-Poly’s cleantech incubator, The NYC Accelerator for a Clean and Renewable Economy (NYC ACRE), are playing a key role in this market growth. For example, Energex Technologies, an environmental monitoring and management company, is working on a first-of-its-kind environmental sensor technology that will allow organizations to assess and monitor critical environmental variables (including temperature, humidity, pressure, air flow, gaps, vibrations, smoke, and pollutants) without the need for multiple sensors, and with estimated maintenance cost savings of up to 60%. Energex is in the vanguard of companies that bridge the gap between traditional, infrastructure-based cleantech companies and IT-driven “cleanweb” companies that develop Web- or IT-based solutions to optimize resource use and accelerate the clean economy. NYU-Poly has also initiated research to support Building Information Models (BIM) to reduce energy use, waste, water, and GHG emissions while improving indoor air quality. It is a priority to incorporate sustainability into the design of campus buildings that are technically satisfactory, economically feasible, and environmentally responsible. Specifically issues of importance include schedules of building components to determine percentages of reuse, recycling, and salvage; better design optimization with parametric programming, and making information required for sustainable design, analysis, and certification routinely available simply as a byproduct of the standard design process. NYU-Poly intends to introduce these topics in courses that are offered. Student research has also encompassed climate change activity. In the last two years, at least six graduate-level research projects in the School of Environmental Engineering & Sciences have investigated the impact of climate change under different emission scenarios on sea level rise, rainfall, temperature, floods/storm surges, water demand for domestic and agricultural uses, and bioclimatic stress/strain on the human body in New York city and state. Through international collaboration with the United Nations Development Programme (UNEDP), the United Nations Educational, Scientific, and Cultural Organization (UNESCO), and other agencies, emission scenarios in other places around the globe including the Middle East have been subject to study and research. A significant number of textbooks and papers have been published by faculty and graduate students addressing the impacts of climate change. CTG Energetics, Inc. 8 NYU-Poly Sustainability & Climate Action Plan 2.1.3. NYU-Poly’s plans to expand community outreach efforts toward achievement of climate neutrality In May 2009, NYU-Poly began a transformation process centered on six driving principles for establishing a successful Capital Improvement Plan: i2e, Green, Engagement Process, Transparent Process, Strategic Planning, and Exemplary Design. A strong governance system established early in the process welcomed input from the entire NYU-Poly community and promoted transparency and collaboration. Several committees composed of faculty, staff members, students, and administration were engaged in the process and included: Steering, Space Planning, Special Projects, Laboratory, and Academic Spaces. Poly has historically hosted community outreach activities, such as the Green Expo, which brings together New York City middle and high school students, NYU-Poly students, and “green” professionals to celebrate Earth Day and learn about sustainability, with the ultimate goal of inspiring the students to pursue science, technology, engineering, and math (STEM) educational and career paths towards becoming the next generation of Green Leaders. Poly will continue to build community support to further its goal of climate neutrality. As an institution built on leadership, Poly strives to model best practices that will benefit the community as a whole. The New York City Mayoral University Challenge - Commitment to 30% Emissions Reduction by 2018 NYU-Poly is participating in the PlaNYC Mayoral University Challenge and has a goal of reducing greenhouse gas emissions from buildings and operations by 30% over the next ten years—or “30 in 10.” University Partners of the Mayoral Challenge are expected to complete two primary deliverables by the end of the first year: (1) complete a campus-wide greenhouse gas inventory; and (2) undertake an action planning process that includes identifying energy conservation and greenhouse gas reduction measures, resulting in a final action plan that includes estimated payback periods and calculations of projected greenhouse gas reduction impact. The mayoral challenge baseline is the 2006–2007 fiscal year, which means that the 30% emissions reduction target date is 2018. Contextual Data – Endowment Size and Operating Budget NYU-Poly’s FY 2008–2009 endowment was approximately $88,000,000, and the FY 2008–2009 operating budget was approximately $103,000,000.7 The amount of money spent on electricity and natural gas for the fiscal year totaled $3,123,700. NYU-Poly’s Climate Action Plan includes a number of measures that require capital and operational funding. A comprehensive analysis was conducted to identify which mix of improvement measures best fits the needs of the campus while staying within defined budgets and the timeline for achieving Poly’s emissions reduction goals. This assessment helped to identify which improvement measures will result in an immediate return on investment; which will require substantial time and capital outlays prior to achieving cost savings; and which are less likely to elicit direct financial returns, but will generate valuable short- and long-term social and environmental benefits. Three potential scenarios were developed and shared with the Capital Improvement Plan stakeholders, as well as with Poly’s Sustainability Task Force. Ultimately, the parties arrived at a plan capable of striking a balance between the immediate functional needs of the campus facilities and the longerterm emissions reduction targets set forth in both program commitments. 7 Data provided by CTG Energetics, Inc. 9 NYU-Poly Sustainability & Climate Action Plan 3. NYU-POLY GREENHOUSE GAS EMISSIONS INVENTORY SUMMARY The ACUPCC and PlaNYC Mayoral University Challenge require GHG inventory reporting for different years (2008-2009 fiscal year for the ACUPCC and 2006-2007 fiscal year for the University Challenge), different data (ACUPCC is more comprehensive), and using different reporting/analysis tools. The GHG emissions inventory for the ACUPCC is based on the Clean Air-Cool Planet Campus Carbon Calculator (V6.4).8 This section follows the reporting needs outlined in the AASHE’s President’s Climate Commitment reporting instructions9. The GHG emissions inventory developed for PlaNYC Mayoral University Challenge is based on the PlaNYC Greenhouse Gas Emissions calculator, version 2010.1, developed by the NYC Mayor's Office of Long-Term Planning and Sustainability. GHG Emissions Inventory Results NYU-Poly’s greenhouse gas emissions are summarized below for the 2008-2009 fiscal year (the GHG inventory with the latest and most comprehensive data). Greenhouse gas accounting practices break emissions into three categories, or “scopes.” Scope 1 emissions are direct GHG emissions occurring from sources that are owned or controlled by the reporting institution. NYU-Poly’s total Scope 1 emissions for the 2008-2009 fiscal year are 3,312 metric tons of CO2 equivalents (MtCO2e). This includes on-site natural gas combustion (used for space heating and water heating), diesel used in the emergency generators, campus-owned vehicle gasoline use, and refrigerants. Onsite natural gas combustion was the primary contributor to Scope 1 emissions for NYU-Poly. Figure 1: Schematic diagram representing the concepts of Scope 1, 2 and 3 GHG emissions Scope 2 emissions include indirect emissions from electricity use. Scope 2 emissions are the result of an institution’s activities but the actual emissions occur at an offsite location under another legal entity’s control (e.g., a power plant). In addition to electricity, purchased steam, hot water or chilled water are typical Scope 2 8 http://www.cleanair-coolplanet.org/toolkit/inv-calculator.php 9 www.aashe.org/pcc/reports/instructions-ghg-report.php CTG Energetics, Inc. 10 NYU-Poly Sustainability & Climate Action Plan GHG emissions encountered on some other college campuses but not applicable at NYU-Poly. The campus’ total Scope 2 greenhouse gas emissions are 3,877 metric tons of carbon dioxide equivalents (MtCO2e). Scope 3 emissions are all indirect emissions not covered in Scopes 1 or 2. Scope 3 emissions are not directly “owned” by the college as a legal entity10, but are nonetheless related to campuses collective activities and accounting for them helps the campus understand its total greenhouse gas emissions from a holistic perspective. ACUPCC institutions agree to count and address Scope 3 emissions resulting from official business air travel and student, faculty, and staff commuting.11 The inventory also optionally included emissions associated with students’ travel from campus to home once per semester. It is not required that these emissions be addressed in the Climate Action Plan. Total Scope 3 emissions during the 2008-2009 fiscal year are 7,082 metric tons of carbon dioxide equivalent (MtCO2e). The Scope 3 emissions required to be addressed by this Climate Action Plan according to ACUPCC requirements are student and faculty commuting, as well as directly financed air travel, both of which total to 1,195 metric tons of carbon dioxide equivalent (MtCO2e). Table 1 summarizes NYU-Poly’s greenhouse gas emissions. 10 From a greenhouse gas accounting perspective, airplane GHG emissions accrue to the airlines, commuting GHG emissions accrue to the individual commuter, etc. 11 Simpson, Walter, Cool Campus!

Reporting Time Period The greenhouse gas inventory period corresponds to NYU-Poly’s Fiscal Year, spanning July through June. The base reporting year is the Fiscal Year of July 2008—June 2009 for the ACUPCC and the Fiscal Year of July 2006—June 2007 for PlaNYC Mayoral University Challenge. 3.1.2. Organizational Boundary The organizational boundary used for this GHG inventory includes the main NYU-Poly campus located in Brooklyn, New York, over which NYU-Poly has direct operational and financial control. NYU-Poly’s buildings located in the Long Island Graduate Center, Westchester Graduate Center, and Manhattan locations are not included in this inventory. The following buildings are included within the boundary: Rogers Hall Complex (comprised of Rogers Hall, Jacobs Academic Building, Jacobs Building and Civil Engineering), Othmer Residence Hall, Dibner Library/CATT Building, and Wunsch Building. NYU-Poly is an affiliate of New York University. This audit does not include any emissions from New York University-owned facilities or operations; New York University conducts an independent GHG inventory for the ACUPCC. 3.1.3. Inventory Process The NYU-Poly GHG inventory was a collaborative effort between NYU-Poly, Jonathan Rose Companies, and The Cadmus Group (formerly CTG Energetics). Cadmus helped guide NYU-Poly and Jonathan Rose in the data collection efforts. In addition, some of the data used in this inventory was derived from an Interim Draft Greenhouse Gas Emissions Inventory conducted by EcoTech International,14 energy audits conducted by Steven Winters Associates for the capital planning process, and related information provided by Jonathan Rose Company. Cadmus assembled the data, entered the data into the Clean Air-Cool Planet calculator, and prepared the greenhouse gas inventory report for the ACUPCC. Additionally, a GHG emissions report was prepared based on the PlaNYC Greenhouse Gas Emissions calculator, version 2010.1, developed by NYC Mayor's Office of Long-Term Planning and Sustainability. Emission factors and warming potentials are from the PlaNYC Greenhouse Gas Emissions calculator, version 2010.1, developed by NYC Mayor's Office of LongTerm Planning and Sustainability. The electricity emissions are based on New York City-specific emissions coefficients provided by the Inventory of New York City Greenhouse Gas Emissions.15 3.1.4.

The Cadmus Group, Inc. 17 NYU-Poly Sustainability & Climate Action Plan 4. EMISSIONS REDUCTION PLAN NYU-Poly Campus Emissions Reduction Strategy The NYU-Poly Climate Action Plan was developed by analyzing a comprehensive set of NYU-Poly campusspecific reduction measures, and then identifying a smaller group of measures within these that most appropriately fit the goals and expectations of the NYU-Poly campus. The selected group of measures needed to stay within realistic budgets, while still meeting the ambitious emissions reduction targets and timelines of the ACUPCC and the PlaNYC Mayoral University Challenge. One of the challenges in developing a concrete set of measures was the rapidly evolving major Capital Improvement Plan for the campus, which will ultimately determine the ability to implement the identified measures within the climate action plan. Given this level of uncertainty, a strategic three-phase emissions reduction plan was developed to be flexible and open-minded. The categorization of measures within these phases included a consideration of the anticipated capital plan implementation timeline, upfront costs and payback, total emissions reduction potential, and overall compatibility with the capital improvement plan. Figure 4 illustrates the methodology behind this approach. Figure 4: NYU-Poly Strategic Emissions Reduction Plan The three phases of the emissions reduction plan will likely overlap with one another, but in general the framework is dictated by: (a) projected time of implementation; and (b) the likelihood that the measure will be implemented. Phase 1 (P1) measures are almost certain to occur or are already being implemented, and serve as a good starting point for campus emissions reductions. The overall reductions from these measures are minimal. Phase 2 (P2) measures have a higher capital cost, and the budget for these measures are not yet accounted for. However, almost all of these measures offer good payback, significantly reduce energy and emissions, The Cadmus Group, Inc. 18 NYU-Poly Sustainability & Climate Action Plan and in general help to improve building performance and occupant comfort. The completion of Phase 2 measures would also allow NYU-Poly to reach the PlaNYC Mayor Challenge by 2018. Phase 3 (P3) measures are the most aggressive measures, and generally have significant ($200,000 or greater) capital costs. The ROI on these measures is not as compelling as that of Phase 2 measures; however they provide the most feasible strategy for NYU-Poly to reach climate neutrality, per the ACUPCC goal. As the final step in reaching climate neutrality, carbon and renewable energy offsets are suggested as a means to net out the remaining GHG emissions. The specific measures of each phase of the plan are detailed in the following sections. NYU-Poly GHG Emissions Forecasting In order to evaluate the potential of the various proposed emission reduction measures, it is necessary to model the anticipated GHG emissions trajectory for the campus if no action is taken, in what is known as a business-as-usual (BAU) scenario. These projections take into predictive factors such as campus building growth and changing emissions factors over time. As a baseline scenario, a BAU GHG emission projection was modeled that represents the anticipated growth of GHG emissions over time if no action is taken to address GHG emissions or energy use. All emission reduction measures are then measured in comparison with this BAU condition. Figure below shows the anticipated BAU GHG emissions trajectory for the NYU-Poly Campus, starting in 2007 (the first GHG inventory year) and ending in 2030 (the target date to reach the ACUPCC climate neutrality goal). GHG emissions are broken apart by Scope as defined in the GHG Inventory (Section 1). The specific factors that influence the GHG emissions projections over time are: 1. Changes in total campus building square footage. Changes anticipated include the demolition of Jacobs Admin Building and Civil Engineering, the leasing of MetroTech Center space, and the planned construction of the Science & Engineering building. These capital changes are modeled to impact Scope 1 and 2 GHG emissions. 2. Student growth. The 10-year campus student growth plan anticipates a 63% growth in student population from 2009 to 2020. Student growth is modeled to impact Scope 3 emissions only. 3. NYC Electricity Emissions Factor. The NYC grid-average emissions factor has been steadily declining, and is expected to decrease by 10% from 2009 to 2020.

The dotted black line shows the PlaNYC GHG emissions intensity reduction target (CO 2e per SF) starting in the year 2018, the target deadline to achieve the 30% reduction. Significant events are shown throughout the timeline such as the GHG inventory baseline year, the leasing of new space, the demolition of vacant buildings, and the new construction of the Science & Engineering building. GHG emissions estimates are dependent on these capital improvements, as well as projected student growth, and a changing NYC electricity emissions factor over time (the NYC grid is expected to be made cleaner). 20 NYU-Poly Sustainability & Climate Action Plan Phase 1 Emission Reduction Measures Near-Term Emission Reduction Measures and the 5-Year Capital Improvement Plan Phase 1 emission reduction measures consist of measures that directly align with the current NYU-Poly 5-YR Capital Improvement Plan. The 5-YR Capital Improvement Plan began in 2009 and all the measures are expected to be complete by 2014. They include a variety of renovations, from structural improvement and fire and safety upgrades to new laboratory space and the tenant fit out of newly leased space in Metrotech Center. The measures suggest low-cost or no-cost energy efficiency best practices when completing specific renovations within the campus for Rogers Hall, Jacobs Academic Building, Dibner Library, Othmer Hall and new tenant fit outs for Metrotech Center. Some of these measures are already being implemented on campus and demonstrate NYU-Poly’s commitment. Total emissions reductions for this Phase are expected to be 482 mTCO2e. The Cadmus Group, Inc. 21 NYU-Poly Sustainability & Climate Action Plan Table 1 lists all the measures included within this phase. A detailed discussion of selected measures is included below by individual building. 4.1.1. Rogers Complex Phase 1 Measures The Rogers complex is the largest and most energy intensive set of buildings on campus. It consists of Rogers Hall, Jacobs Academic Building, Civil Engineering and Jacobs Administration Building. As part of the capital plan, the Civil Engineering and the Jacobs Administration Building will be demolished. Jacobs Academic, the newest building in the complex will receive some minor upgrades. Rogers Hall, the largest building in the complex and of the campus will undergo some major renovations. These planned renovations provide a significant opportunity to improve the energy performance of the building and thus reduce GHG emissions. P1.1 Integration of Lab21 best practices for New Laboratory Space: The repurposing and design of new laboratory space from existing classrooms and other spaces is identified below as a major opportunity. These measures directly coincide with the following Capital Plan: o o o Renovation of 5,800 sf of existing classrooms into equipment-based laboratories Renovation of 3,800 sf of existing classrooms into wet laboratories i2e equipment-based laboratory creation via consolidated space (1,000 sf) Figure 6: Example state-of-the-art chemistry lab renovation with filtered fume hoods and LED lighting During the renovation of these spaces there are a number of design best practices that should be considered, and incorporated as appropriate to the space (see Labs21 Best Practices below). The Cadmus Group, Inc. 22 NYU-Poly Sustainability & Climate Action Plan LABS21 B EST PRACTICES Laboratories typically consume large amounts of energy, often 3—4 times more than offices per square foot. Along with the typical lighting power and office-type equipment plug loads, a large amount of this energy consumption comes from stringent ventilation-related requirements, as well as large plug loads from specialized laboratory equipment. Heating and cooling is typically run 24 hours per day unlike the typical 8— 5 occupant schedule load-driven HVAC systems of an office building. NYU-Poly plans on building both Webbased and equipment-based laboratories. Web-based laboratory consumption will be dominated by fume hood use and large plug loads with internal heat gains from specialized equipment (e.g. refrigerators, ovens, centrifuges, pumps, water baths, spectrometers, etc.). Equipment-based laboratories will have significant computer equipment plug loads, and server rooms and network equipment that will require constant cooling. Appropriate design strategies for these unique spaces can greatly reduce energy consumption. Typical best practices for laboratory design and operations include: Zone segregation of energy-intensive process operations tasks to avoid unnecessarily ventilating and cooling non-critical zones Right sizing equipment and accounting for an appropriate diversity factor. Laboratory HVAC systems in particular tend to be oversized because equipment (e.g. fume hoods) is assumed to be running all the time while in reality this is often not the case. VAV Supply and fume hood exhaust systems and \ variable frequency drives on pumps and fans Specify premium high-efficiency equipment. Because of the high utilization of equipment and energyintensive nature of laboratories, the payback on these purchases will be shorter than in a typical building. Reduce Static Pressure Drop with best practices duct design and low face-velocity coils and filters. Energy recovery from exhaust air or process cooling water (e.g. enthalpy wheels) Incorporate energy monitoring and control systems with direct digital controls. Meter HVAC, lighting and plug loads separately, so that along with proper controls, staff training and maintenance, systems can operate efficiently and optimally. Lighting- Occupancy sensor controls and daylighting controls (where appropriate) Lighting - Energy efficient lamps and ballasts Daylighting to allow for daytime lighting load reduction and improved occupant experience Task Lighting with occupant controls For more information and tools on designing laboratory space efficiently and effectively, refer to the Labs21 program and tool kit (http://www.i2sl.org/resources/toolkit.html). P1.2 Rogers Café & Corridor - 3,000 sf renovation (completed) One of the early action items included in the NYU-Poly i2e transformation and campus Climate Action Plan included the renovation of the Rogers Hall Café and Corridor, a central artery and gathering space on campus. Energy and emissions savings related measures from this renovation included reduced lighting density and the additional use of daylighting. These measures both reduced energy use and improved indoor occupant satisfaction. Total savings here were estimated at 5,250 kWh (2 MtCO2e) annually. The Cadmus Group, Inc. 23 NYU-Poly Sustainability & Climate Action Plan Figure 7: The newly renovated Rogers Hall Cafe with lighting and daylight harvesting enhancements P1.3 Rogers Hall Restroom Infrastructure Improvements: 3 restrooms (completed) Another early action item at Rogers Hall was to reduce lighting density and remove core radiators in restrooms that were unnecessarily overheating the space. This will reduce energy use and improve occupant comfort. This measure was implemented in 2010 and estimated savings are 13,500 kWh (2 mTCO2e) annually. P1.4 Retro Commissioning of Rogers Hall Café and IT controls (completed) Improved controls means less energy used when it is not needed. This measure was implemented in 2010. Monitoring of operations and adjustments to controls should be performed as needed and on a continuous basis. 4.1.2. Dibner Library and Othmer Hall Measures Capital Plan aligned Phase 1 reduction measures at Dibner Library and Othmer Hall include: P1.5 Dibner Library Roof Replacement A new “cool roof” for Dibner Library will reduce energy use for the building due to both improved insulation and a highly reflective surface that reduces heat gain. If implemented, this measure will result in an estimated 126,500 kWh reduction in facility energy use and a 27 mTCO2e emissions reduction by 2014. P1.6 Retro commissioning – Dibner mechanical systems and controls (partially completed) The Cadmus Group, Inc. 24 NYU-Poly Sustainability & Climate Action Plan The control system at Dibner has been both problematic and is fast approaching the end of its useful life. The system is primarily direct digital control (DDC), but some areas of the building still utilized pneumatic controls. In addition, the control logic algorithms appeared to have been overridden so that the building is operating at a very sub-optimal level, leading to continuous equipment operation, occupant discomfort, and wasted energy. Retro-commissioning the systems and controls can help return the building to original specifications. This effort has already begun, and digital controls have replaced the pneumatics. A full retro-commissioning of these new controls is projected to save 693,221 kWh annually and reduce annual emissions by 151 mTCO2e. P1.7 Othmer Hall Roof Replacement A new “cool roof” for Othmer Hall will reduce energy use by decreasing the cooling load in the summer months. If implemented, this measure will result in a 10,100 kWh reduction in facility energy use and a 3 mTCO2e emissions reduction by 2014. P1.8 Othmer Hall Retro-commissioning - cooling fan and pump controls (partially completed) Othmer is a building with average HVAC systems with below average performance. Analysis of the utility data shows a consistently high electric base load consumption that cannot be fully explained by higher-than-normal occupant related loads or even inefficient lighting. Typically, when no obvious reasons can be identified to account for higher than normal electricity consumption, the problem is related to the control and operation of the building systems and the building is a candidate for retro-commissioning (Retro-Cx). SWA analyzed outputs from the Honeywell Building Management System and observed conditions that suggested the variable speed controlled fans and pumps are not ramping down at times of low demand. Continuous operation at full power of the fans and pumps running could explain the consistently high electric consumption observed in the bills. Estimated savings potential for this measure is 153,092 kWh and 48 mTCO2e. 4.1.3. Metrotech Center Build-Out Measures P1.9 Plug Load and Lighting Best Practices in Metrotech Center NYU-Poly will also be leasing more space at the Metrotech Center. This new space will house faculty offices and research spaces for two (2) academic departments; specifically the Computer Science Engineering Department (CSE) and Electrical & Computer Engineering Department (ECE). It will also contain five (5) general classrooms (approximately 40 seats), and a computer server room that will house the servers for the University, CSE departments, and research functions. In addition, the leased areas will have conference rooms, lounge and pantry areas, and file storage space. The leased space will be occupied as-is wherever possible, but some alterations (such as new carpeting, painting and lighting retrofitting) will be required. NYUPoly will attempt to reduce plug loads and lighting power density where possible, as this can translate into significant savings. Typical best practices for reducing lighting and plug loads during design are shown below. The Cadmus Group, Inc. 25 NYU-Poly Sustainability & Climate Action Plan R EDUCING PLUG LOADS - BEST PRACTICES Plug loads both consume electrical energy and generate heat, which is then removed from the space by the air conditioning system. In many office buildings, the heat released by plug loads and lighting systems can require air conditioning year around. The following best practices should be followed wherever applicable to help reduce plug loads: Smart power strips with either scheduling capabilities or occupancy sensors should be used when possible. All computers should be set to hibernate after five minutes of inactivity. “Hibernation” sets the computer into a standby state, reducing energy use. Procedures for use of screen savers, games and general computer configuration should be established to ensure that hibernation mode is not affected. Portable plug-in watt meters should be provided for use by staff to check electrical consumption of miscellaneous electrical devices to enable them to measure and understand their individual consumption. The electrical system should be configured for floorby-floor plug load metering. Use of plug-in fans, heaters and refrigerators should be prohibited in work stations and offices. These seemingly small loads can actually be very significant, especially in the case of small plug-in space heaters. ENERGY STAR qualified equipment, where applicable, both in the office (such as copiers, scanners, and printers) and in the kitchen (microwaves, vending machines, refrigerators) when possible is recommended. The Cadmus Group, Inc. 26 NYU-Poly Sustainability & Climate Action Plan LIGHTING BEST PRACTICES In a typical office building, lighting can account for anywhere from 20% to upwards of 45% of total energy use. Often time’s significant energy savings can be realized with a minimal investment of capital and common sense. Installing and maintaining photo-controls, time clocks, and energy management systems can also achieve extraordinary savings. Some practices to keep in mind are: Utilize daylighting whenever possible. Using natural light to illuminate areas instead of electric lights is an easy way to achieve significant savings. In addition, improvements in sensors and photo-cell controls make it possible to automate much of this progress, so that the electric lights will automatically turn themselves on or off and/or dim as necessary. Automated shade controls can be implemented in daylight harvesting situations to provide shade during times of day where solar glare is an issue, and offering maximum daylight at other times. Without automated shade controls, often many daylight harvesting opportunities are missed because shades remain down throughout the day. Maintain proper light levels. Over-illuminating a space not only wastes energy, it can decrease occupant comfort. Use energy efficient bulbs and fixtures. Upgrading to high efficiency fixtures will allow you to maintain lighting levels while using less energy, as more efficient fixtures lose less energy as heat. Task lighting. Task Lighting provides good illumination only in the areas where the task is being performed, while the general lighting level is lower. If sensibly implemented, this can reduce the number of general lighting fixtures, reduce the wattage of lamps, save considerable energy and provide better illumination. Automated controls. Proper use of timers, light sensors, and occupancy sensors can result in significant energy savings by turning off lights when they are not needed. Proper maintenance. Maintenance is vital to lighting efficiency. Light levels decrease over time because of aging lamps and dirt on fixtures, lamps and room surfaces. Together, these factors can reduce total illumination by 50% or more, while lights continue drawing full power. Taken together and based on reasonable plug load reductions (0.5 W/SF reduction from typical) and lighting load reduction (0.5 W/SF from typical) estimates, these best practices can result in a projected 372,882 kWh reduction in Metrotech energy use and an 117 mTCO2e emissions reduction by 2014. 4.1.4. Combined Phase 1 Summary If all of the above measures are implemented, they will result in a total 1,972,873 kWh reduction in campus energy use, with MTCO2e emissions reduced by approximately 482 mTCO2e. This is equal to 6% of total campus building emissions (Scope 1 and 2) or 5% of total campus emissions (all Scopes). The full implementation of Phase 1 measures will be a strong first step and demonstrates NYU-Poly’s commitment to energy and GHG emissions reductions. However, in order to achieve the PlanNYC 30% reduction target, additional reductions are needed. Phase 2 (Section 0) measures outline a potential set of additional measures that will allow NYU-Poly to reach this target.

The dotted black trend line represents the necessary emissions level to achieve the PlaNYC 30% carbon emissions reduction target (based on emissions intensity per SF). The red line shows the projected emissions if all the proposed Phase 1 emission reduction measures are completed. The 5-yr capital plan is projected to be completed by 2014 and the Science & Engineering building is expected to be operating by 2022. Additionally, these projections account for the demolition of Civil Engineering building and Jacobs Administration building, and the lease out of approximately 81,000 SF of space in MetroTech Center. The Cadmus Group, Inc. 29 NYU-Poly Sustainability & Climate Action Plan Phase 2 Emission Reduction Measures Mid-Term Emission Reduction Measures to Reach the PlaNYC Reduction Target Phase 2 emissions reductions focus on cost-effective measures with good paybacks to fit a total budget that was approximately $1,500,000. NYU-Poly currently has $500K designated for broadly for sustainability improvements on the campus. The funding for many of these measures could be leveraged by these funds, with additional grant opportunities from NYSERDA that would be able to cover some of the remainder. Many of these measures were identified by the ASHRAE Level II energy audit conducted by Steven Winters & Associates (SWA). Steven Winters Associates completed a series of ASHRAE Level II building energy audits for all buildings on campus between December 2009 and March 2010. These audits were based primarily on visual observation of the buildings, system controls and analysis of energy billing data, as well some limited field testing of boiler combustion efficiency and lighting illuminance level testing. When combined, these measures will result in a 30% reduction in carbon intensity from the 2007 baseline (CO2e per sf of building space) by the year 2018, meeting the PlaNYC reduction target. 4.1.5. Rogers Complex Phase 2 Measures P2.1 Rogers Hall Core Overheating - Remove core radiators (in process) Perimeter radiators in corridor and restrooms of Rogers Hall are no longer needed due to the Jacobs Academic Building addition. Theses spaces are now effectively core spaces and are overheated. In fact there are three separate heating systems being used. The campus is currently in the process of picking a single system to continue using, while removing the other systems. It is estimated that the removal of 40 unneeded radiators would result in total savings of 164,120 kWh and will reduce emissions by approximately 30 mTCO2eonce implemented. The estimated cost of this is measure is $70,000 with a payback of 10 years. P2.2 Civil Engineering High Pressure Steam Boiler – Replacement (in process) Currently, the 80 psi High Pressure Steam boiler in the basement of the Civil Engineering building is used to heat domestic hot water through a heat exchanger, and is used to provide high pressure steam to a 4th floor lab in Rogers Hall. The lab only uses this steam for 12 weeks out of the year, but it is provided every day from 6am to 9pm. Improved scheduling of the boiler, combined with alternative ways to generate domestic hot water could result in significant energy savings. Projected energy savings are 131,882 kWh, with an associated emissions reduction of 24 mTCO2e. As of 2012, the scheduling and replacement of the existing steam boiler is in design. P2.3 Rogers Complex Insulate Condensate Return Valves Most, if not all, condensate return tanks, piping, and pumps are not insulated. Insulating these will reduce waste heat, thereby saving energy and increasing occupant comfort. Estimated savings potential for this measure is 146,536 kWh and 26 mTCO2e. The estimated cost of this is measure is $18,500 with a payback of 3 years. P2.4 Rogers Hall VAV Fume Hood Systems Variable air volume (VAV) fume hoods respond to variable sash openings to keep face velocities and fume capture constant, while reducing the total volume of conditioned makeup air to a minimum. The nominal baseline condition is currently 72,000 cfm of continuously conditioned outdoor air. Heating this volume of The Cadmus Group, Inc. 30 NYU-Poly Sustainability & Climate Action Plan outside air could represent about 50% of the heating load for the Rogers Complex. This measure could reduce annual energy use by 1,709,759 kWh with an associated emissions reduction of 361 mTCO2e. The estimated cost of this is measure is $450,000 however the payback is less than 4 years. This measure is one the most impactful steps that NYU-Poly can take reduce energy and energy costs over time. As newer ventilation code requirements for laboratories will need to be addressed, this measure could result in even greater savings on an annual basis than projected. P2.5 Jacobs Academic Building (JAB) Controls Retro-commissioning There are currently several issues with the controls for equipment in the JAB building, which is contributing to the following issues: AHUs not running (ACS C1), Secondary pump failures on multiple systems Excess outdoor air in economizer mode during winter VAV supply flows typically less than 50% of setpoint Low supply duct static pressure Return fans not running Exhaust fans not running Retro commissioning of the control system, and testing/balancing of the air handling and pumping systems, can result in significant savings. Projected energy savings from this measure are projected to be 353,071 kWh and 90 mTCO2e. The estimated cost of this is measure is $110,000 with a payback of less than 5 years. P2.6 Rogers Complex Daylight Harvesting and Controls The installation of on/off daylighting controls for glazed JAB corridors can help keep lighting at nominal levels with less electricity. Additionally Rogers Hall has a number of perimeter spaces, including classrooms and offices where daylight harvesting is feasible. Daylighting controls will turn off the electric lights when the amount of natural daylight entering the space is sufficient to maintain 40 foot-candles or more. For many areas, a simple photocell on/off control methodology is expected to be the most cost effective approach. In classrooms and other high occupancy areas, continuous dimming ballasts with closed loop photocell control could help to maintain target light levels. Estimated savings potential for this measure is 88,986 kWh and 28 mTCO2e. To reasonably estimate the cost of this is measure, the building’s daylighting potential needs to be evaluated on a space-by-space basis. P2.7 Rogers Hall LED exit signs All remaining incandescent exit signs should be replaced with LED exit signs with lighting power of 5 watts or less per face. This will result in anticipated savings of 30,000 kWh and 9 mTCO2e. The estimated cost of this is measure is $44,000 with a payback of 8 years. The Cadmus Group, Inc. 31 NYU-Poly Sustainability & Climate Action Plan 4.1.6. Dibner Library Measures P2.8 Dibner Library Daylight Controls Light levels in the ground floor corridor running from the main entrance past the auditorium and on the third and fourth floors of the library reading stacks 8 feet from the windows at the individual study areas were measured. In each instance, recorded light levels exceeded illumination levels recommended by the IESNA for corridors and library reading areas. Installing automatic controls in the identified spaces capable of turning off the electric lights when the amount of natural daylight entering the space is sufficient will result in projected energy savings of 30,900 kWh and will reduce emissions by 9 mTCO2e. The estimated cost of this is measure is $4,000 with a payback of less than 1 year. P2.9 Dibner Library Air Cooled Chiller Upgrade A glycol chiller loop provides cooling to various fan coil units and small packaged AC units serving core spaces that require cooling throughout the year. Replacing the existing chiller with a model capable of taking advantage of free cooling will allow the unit to exploit cold outside air temperatures to cool the chilled water instead of running a compressor. Free-cooling chillers employ a heat exchanger through which chilled water is diverted when favorable outside air conditions occur. Estimated savings potential for this measure is 89,572 kWh and 27 mTCO2e. The estimated cost of this is measure is $95,000 with a payback of less than 6 years. P2.10 Dibner Lighting Fixture Upgrade (T12 to HPT8) Currently, the majority of the lighting at Dibner is being provided by linear fluorescent troffer style T12 lighting fixtures with bulbs rated at either 40 or 34 Watts. Replacing these with high performance (HP) T8 fixtures could result in significant savings (Projected 218,372 annual kWh savings, with emissions reduced by 83 MTCO2e). High performance T8 systems are comprised of low-wattage lamps and high-efficiency ballasts and provide longer lamp lives and higher light output at lower wattage. Retrofit kits are suggested to convert the 3 bulb T12 fixtures to 2 bulb high performance T8s. This will reduce the overall installed wattage, while keeping light at acceptable levels. The estimated cost of this is measure is $196,000 with a payback of less than 5 years. 4.1.7. Othmer Hall Measures P2.11 Othmer Hall Condenser Pump Impeller Trimming The 30HP condenser water pumps at Othmer have been significantly throttled back indicating that the pumps are oversized and that the operating head and (or) flow rate are greater than the process requirements. For oversized and throttled pumps, trimming the impeller is a low cost method of tuning the pumps to operate at the point that corresponds to the pressure and flow characteristics of the systems they serve. Trimming the impeller reduces the speed at the impeller’s tip, which reduces the amount of energy imparted to the water being pumped. As a result, the pump’s pressure and flow rate decrease, throttling is no longer The Cadmus Group, Inc. 32 NYU-Poly Sustainability & Climate Action Plan necessary and the pumps can operate at their optimal efficiency. Estimated savings potential for this measure is 26,845 kWh and 8 mTCO2e. The estimated cost of this is measure is $10,000 with a payback of 2 years. P2.12 Othmer Hall Overheating Reduction Controls Recorded space temperatures in Othmer have been in excess of 80F during the heating season, and the heating systems were enabled. The sequence of operations for the absorption chillers/heaters specifies the supply temperature of the hot water in the heating loop be capable of being reset based on outside conditions, but does not specify the minimum temperature. Applying a hot water reset schedule customized for the building that accounts for the solar gains experienced by Othmer can help to reduce this overheating. Estimated savings potential for this measure is 549,010 kWh and 99 mTCO2e. The estimated cost of this is measure is $35,000 with a payback of less than 2 years. P2.13 Othmer Hall Common Areas Lighting Retrofit Othmer Hall could realize significant energy and emissions savings from a lighting retrofit. 80% of the building lighting load comes from common areas such as corridors, elevator banks, laundry rooms and lounges. Measures such as de-lamping areas with excess available lighting (i.e. Residential Corridor), replacing inefficient fixtures with high efficiency LEDs and utilizing daylighting where possible will result in significant savings. See the Lighting Best Practices section for more information. A comprehensive retrofit is projected to reduce energy consumption by 309,020 kWh, with an associated emissions reduction of 97 mTCO2e. The estimated cost of this is measure can vary significantly depending on the extent of the retrofit. 4.1.8. Wunsch Hall Measures P2.14 Replace Incandescent Lights Currently, Wunsch Hall has several recessed parabolic reflector incandescent flood lights installed. Replacing these with 23 Watt CFLs will result in energy savings, and has a very short payback period. Energy savings from this measure are projected at 683 kWh. The cost of this measure is nominal, with a payback of months. P2.15 LED Exit Signs All remaining incandescent exit signs should be replaced with LED exit signs with lighting power of 5 watts per face or less. This measure is projected to save 1,500 kWh. The estimated cost of this is measure is $2,200 with a payback of less than 8 years. 4.1.9. Campus-Wide Buildings - Emission Reduction Measures The following measures generally apply to all the buildings on campus, rather than any one particular building. P2.16 PC Power Management There are currently a large number of PCs that are fully on when this is not necessary, such as at night or during semester breaks. Using existing power saving settings (such as setting monitors to sleep and the PC to The Cadmus Group, Inc. 33 NYU-Poly Sustainability & Climate Action Plan hibernate after a certain period of no activity has passed) can result in savings. Implementing this measure in all applicable facilities will save a projected 94,800 kWh and will reduce emissions by 28 mTCO2e. There are no capital costs associated with this measure. P2.17 Vending Machine Power Savings Multiple leased vending machines are present on the NYU-Poly campus. Requesting ENERGY STAR™ label machines when the lease is up for renewal will result in savings. Also, the addition of power strips with scheduling controls and/or occupancy sensors will help trim energy use by powering down the machine during hours when the building will not be occupied. This measure will reduce energy use by 27,456 kWh and emissions by 9 mTCO2e once implemented. The estimated cost of this is measure is $6,600 with a payback of less than 2 years. P2.18 Bi-Level Lighting in Stairwells Currently the stairwell lights in many of the buildings on campus operate at full power 24 hours per day despite very low or intermittent use. Installing bi-level lighting fixtures in the stairwells capable of detecting the presence of occupants, by either Passive Infrared Sensors (PIR) or ultrasonic motion sensors, will reduce the power consumed by the fixture when the stairs are unoccupied. This measure is projected to save 20,160 kWh a year, and will reduce emissions by 7 mTCO2e annually. The estimated cost of this is measure is $72,000 with a payback of approximately 18 years. The Cadmus Group, Inc. 34 NYU-Poly Sustainability & Climate Action Plan 4.1.10. Combined Phase 2 Summary If all of the above measures are implemented, they will result in a total 4,021,979 kWh reduction in campus energy use, with MTCO2e emissions reduced by 911 mTCO2e. This is equal to 11% of total campus emissions (ACUPCC Scope). Combined with Phase 1 measures this would result in a 28% reduction in building carbon intensity (PlaNYC scope). The expected additional cost associated with Phase 2 measures is approximately $1,500,000. Complete implementation of these measures is projected to be completed by 2016. It is also projected that by 2022, the new Science & Engineering building will be completed. Under Phase 2 projections, it is estimated that the energy efficiency of the new building will be 10% greater than a typical building, a modest expectation that is on par with the kind of efficiencies that other Phase 2 measures propose. In Phase 3, more aggressive measures are suggested for the Science & Engineering building.

The Cadmus Group, Inc. 37 NYU-Poly Sustainability & Climate Action Plan Phase 3 Emission Reduction Measures Big and Bold Emission Reduction Strategies and Campus Sustainability Measures Phase 3 emissions reductions focused on what it would take to get truly deep reductions in GHG emissions and be able to achieve climate neutrality as defined by the ACUPCC. The following is a summary of Poly’s aspirations to achieving climate neutrality. There are no definite commitments to meet these measures at this time, but rather concepts which are being explored. The feasibility of incorporating these strategies is based on economics and imminent need. 4.1.11. Rogers Complex Measures Potential measures at the Rogers Complex could include the following measures. P3.1 Rogers Hall Labs – Exhaust Air Energy Recovery For additional savings in the new and renovated lab spaces in Rogers Hall, a sensible only heat exchanger is recommended. This would isolate the exhaust air stream from the makeup air stream which is desirable for contaminated exhaust. Heating and cooling energy savings from this measure will be slightly offset by the increase in fan power required to move air through the heat exchanger. Overall, this measure is projected to reduce energy use by 909,719 kWh, with an associated emission reduction of 154 mTCO2e. The estimated cost for this measure is $300,000 with a payback of approximately 10 years. Payback could be shorter for this measure if ventilation is increased due to code requirements. P3.2 Rogers Hall – Central HVAC System Upgrade NYU-Poly is considering the installation of a central HVAC system to replace the current mix of 188 window AC units, water cooled units, and city water cooled units that are mostly at the end of their useful lives. Replacement options include central electric chillers, modular electric chillers, expanded gas fired absorption chiller capacity, or self-contained AC units. A separate master plan study of the MEP systems has been recommended to evaluate the options. As a preliminary estimate, Steven Winter & Associates calculated the potential energy savings of installing self-contained AC units to be 265,000 kWh annually, with emissions reduced by 83 mTCO2e. Self-contained AC units are a good choice because they are modular and can be installed on an ongoing basis as the building is being renovated. P3.3 Rogers Complex - Upgrade Cooling Towers with VFDs The existing building has several small cooling towers with on/off controls for the constant speed fans. If the central HVAC system will be upgraded and a large central cooling tower installed, it would be advantageous to install variable frequency drives (VFDs) on the fans. This measure is projected to reduce cooling energy consumption by an additional 25,000 kWh and emissions by 8 mTCO2e. P3.4 Rogers Hall - Window Replacement Rogers Hall currently uses operable single pane windows in steel frames that are in poor condition. New windows should be installed that minimize water infiltration, improve building appearance, and improve occupant comfort. Approximately 700 4’x8’ windows are in need of replacement. The existing single pane windows have an overall heat transfer coefficient of approximately U = 1.0. Thermally broken double pane insulated units should have an overall heat transfer coefficient of approximately U = 0.5 or better. Energy The Cadmus Group, Inc. 38 NYU-Poly Sustainability & Climate Action Plan savings from new windows will primarily be in the winter season. If all windows were replaced, energy use could be reduced by as much as 380,992 kWh annually, with emissions dropping by 88 mTCO2e. P3.5 Rogers Hall - Whole Building Lighting Retrofit A building wide lighting retrofit of Rogers Hall could result in significant energy savings. SWA found that many of the space in Rogers Hall are over lit and lighting is misplaced and poorly utilized. Lowering the lighting power density from the current 1.6 W/sf to 1.2 W/sf (recommended under ASHRAE 90.1.2007) is easily achievable without affecting occupant comfort or having to rely on expensive lighting technologies. More aggressive measures such as installing LED technology, occupancy sensors and daylight sensors could further reduce lighting energy use. Refer to the Lighting Best Practices section for more information. Projected energy savings for this measure are 1,375,146 kWh, with emissions projected to fall by 432 mTCO2e as a result. P3.6 Rogers Hall - Replace Kitchen DHW Boilers with Solar DHW System Currently, domestic hot water for the Rogers Hall Kitchen is provided by an atmospheric boiler. These boilers tend to have low up-front costs, but also low efficiency. Replacing this boiler with a more efficient (one) will reduce energy costs. To aggressively reduce emissions to meet climate commitments it is recommended that NYU-Poly consider the feasibility of a Solar DWH system. Anticipated savings for this kind of replacement are expected to be 990,367 kWh annually, with emissions being reduced by 178 mTCO2e. Alternatively a less aggressive but less capital cost intensive strategy would be to purchase high efficiency condensing boilers. Also note potential synergies here with the Microgrid (measure P3.10), and the potential to use waste heat recovery to supply hot water. 4.1.12. P3.7 Othmer Hall Measures Othmer Hall - Active Occupant Energy Management Othmer Hall has the second-highest energy density of all the buildings on campus. Occupant behavior may play a large role in this. Currently, electricity in Othmer is master-metered: students are not directly billed for the amount of electricity they use in their rooms. In master metered situations, it is common for tenants to perceive their electricity as “free” or to not even be fully aware of their electricity use. That mentality combined with the extensive use of electronics such as laptops, iPads and smartphones can lead to significant energy costs. Several approaches to reducing occupant electric usage are described below and they should be considered as part of future campus upgrades. (a) Raising occupant awareness regarding their energy use. Signs in the common areas on each floor could be posted with tips for saving energy within their rooms. These signs would serve as constant subtle reminders to the students that they are using energy and that they probably could be using less. Incoming residents could be given an energy saving tips brochure in their orientation materials. Public display of real-time electric usage of the building from interval electric metering has also been shown to influence occupant energy use using energy dashboards in lobbies and common areas. (b) Provide “smart strip” power strips for dorm rooms. Plug loads such as printers, desk lamps, and computer monitors can be controlled by individual “smart strip” power strips that turn OFF noncritical loads to save energy. Smart strip control technologies include programmable timers, occupancy sensor-based systems, and a technology based on equipment signature and usage analysis. The Cadmus Group, Inc. 39 NYU-Poly Sustainability & Climate Action Plan (c) Active management of room loads by key cards. A state-of-the-art approach used by hotels is a key card energy management system. A stand-alone key card system requires an occupant to insert a key into a master switch to turn on the electricity in the room. The same key is usually used as the door key, so people have to take it with them when they leave, which then turns off the electricity in the room. Key card systems also have the capability to interface with fan coil thermostats to put the units into a setback mode when the keys are removed and occupants leave. Key card systems are considered emerging technologies by the American Council for an Energy Efficient Economy and may not be a cost effective retrofit. Implementation of Occupant Management Practices is projected to be able to save up to 165,331 kWh, with emissions reduced by 63 mTCO2e as a result. P3.8 Othmer Hall - Replace Atmospheric boiler with Solar DHW System To aggressively reduce emissions to meet climate commitments, it is recommended that NYU-Poly consider the feasibility of a Solar DWH system, similar to the one proposed for Rogers Hall to replace the six atmospheric boilers that currently operate. Projected energy savings for this measure is 708,224 kWh, with emissions being reduced by 127 mTCO2e. 4.1.13. P3.9 Science & Engineering Building - New Construction Science & Engineering Building– High Performance Design As part of the long-term vision of the Polytechnic Institute of NYU’s i2e Campus Transformation, the site currently occupied by the Jacobs Administration and Civil Engineering buildings will be demolished and redeveloped into the Science & Engineering building. The vision for this development is in two sections. The lower section will be designated for academics and research (laboratory spaces, classrooms, etc.), with a possible residential tower above that for student housing, and retail space on the ground floor. It will be a fully mixed use-building, prominently located on a high-volume corner of downtown Brooklyn with direct access to outside street and pedestrian traffic. It is intended to showcase the work of an elite engineering school and incorporate various, high-visibility envelope and building system technologies on its facade. This bold vision for the site is also a tremendous opportunity to reduce future energy usage and GHG emissions savings at a cost that would be much lower than having to renovate an existing building to achieve similar savings. The following descriptions include various high performance design features, concepts and technologies broken apart by building system. These examples and other like them should be considered and incorporated as early as possible in the design phase to ensure the most successful implementation of high performance design as possible. The ability for the building to adapt to changing programmatic needs over time has been early on identified as an important aspect to incorporate into its design. Many of the recommendations below were selected with this in mind. The Cadmus Group, Inc. 40 NYU-Poly Sustainability & Climate Action Plan Figure 12: A possible rendering of what the Science & Engineering building could look like, situated at the corner of the campus. The Cadmus Group, Inc. 41 NYU-Poly Sustainability & Climate Action Plan HIGH PERFORMANCE BUILDING ENVELOPE TECHNOLOGIES A high performance building envelope design offers opportunities to significantly reduce HVAC energy use, can improve indoor thermal comfort, increase daylighting, improve aesthetics, and enhance occupant experience. Some technologies to consider are: o Double Skin Façade – A double skin façade is a system consisting of two glass skins that forms an intermediate cavity between the building and the outside. During the heating season, the solar gain within the cavity can be circulated to the occupied space to offset heating requirements. During the cooling season, the double skin façade works as a screen for solar heat gain, and with a correct design, warm air inside the cavity can be ventilated out, carrying additional heat with it. The double skin façade also allows for an effective way to naturally ventilate the space, and for night time ventilation to pre-cool the building. A double skin façade system that is ideal for both heating and cooling conditions is possible but needs to be designed carefully to function as intended. o High Performance Glazing – This includes technologies such as: (1) high-R value windows (triple pane); (2) spectrally selective window films that reduce solar heat gain; (3) electrochromic glass, where electrical energy is used to transition between clear and darkened states. Darkened glass transmits less light and reduces heat gain when darkened, especially in dual-pane windows. o Phase-Change Materials Enhanced Building Envelope – Phase change materials can be installed behind walls, ceilings, around ducts, and integrated into the roofing of buildings. These biobased materials are designed to change phase at very precisely specified temperature ranges and serve as highly effective thermal energy storage. They absorb heat from internal gains during the day and releasing this heat during unoccupied hours, thus greatly reducing the load on HVAC the system and saving significant energy. o \ Cool Roof - The majority of solar heat gains come through a roof. Cool roofs are highly reflective roof that significantly reduce the amount of solar radiation absorbed and reduces airFigure 13: phase change material applied to drop-ceiling conditioning costs. They also have a high emissivity (greater than 80%) which readily reflects any absorbed heat back into the atmosphere. This is a low-cost energy efficiency feature that can be applied to roofs, as well as any rooftop ducting or rooftop cooling units. The Cadmus Group, Inc. 42 NYU-Poly Sustainability & Climate Action Plan HIGH PERFORMANCE HVAC SYSTEMS & TECHNOLOGIES There are a variety of different heating, cooling and ventilation systems that could be used to very effectively and efficiently condition the space within the building. Because the building will have a variety of different space uses (laboratory, office, classroom, dormitory), it should be expected that the loads from these zones will be significantly different. A system should be chosen that can accommodate all these types of zones. Some example technologies here include: o Chilled Beam Systems – In the system, chilled water is piped through fin tubes located on the ceiling which drives a convection cycle where warm air rise to ceiling, is cooled by the chilled beam and then falls back to the floor, saving fan energy by relying on natural convection cycles instead. These systems are gaining popularity in lab spaces, where it allows cooling loads and ventilation loads to be completely separated. o Dedicated Outdoor Air Systems (DOAS) – DOAS allow you to separate ventilation loads from cooling and heating loads and work well with other technologies such as chilled beams, heat energy recovery systems and IEQ-based ventilation systems. DOAS can be a particularly cost effective strategy for laboratory spaces that have heightened and specific ventilation requirements. o IEQ-Based Ventilation and Lab Management – This technology involves reconsidering the appropriate levels of air changes per hour (ACH) in the \laboratory environment. In lieu of maintaining one recommended flow rate 24/7, new, sophisticated monitoring systems can operate laboratories under reduced ACH for more than 90% of the time, constantly monitoring the lab air, and, in case of detecting an IEQ incident; automatically increase the ACH to purge contaminated air. These systems can easily be applied to flexible areas in the laboratory where the need might vary from dry to wet environments o Desiccant Cooling Technologies – Desiccant cooling systems work well in hot humid climates where dehumidification of supply air is desirable. Desiccant systems work in conjunction with conventional air conditioning systems to dehumidify the air, improving indoor thermal comfort, and reducing cooling costs. o District Heating and Cooling - Assuming waste heat recovery will be available from the Microgrid project, cooling loads can be supplied by absorption chillers should be, and heating loads can be supplied by heating hot water, both using waste heat recovery from the onsite generation plant. o Solar Domestic Hot Water System – If waste heat recovery from the Microgrid is not sufficient to meet DHW needs, a rooftop Solar DWH system should be considered. For other laboratory specific HVAC design practices see measure P1.1 (Labs21 Best Practices). High Performance Lighting & Plug Load Management Plug loads” are all of the computers, printers, task lights, and other equipment plugged into the outlets. This is an “unregulated” load that building energy codes do not control, and which represent a growing portion of building energy use. Both high performance lighting design and plug loads management offers opportunities to greatly reduce energy use, particularly in buildings where HVAC loads are already being minimized. See measure P1.9 (Lighting Best Practices and Plug Loads Best Practices) for specific recommendations on reducing these loads. The Cadmus Group, Inc. 43 NYU-Poly Sustainability & Climate Action Plan BUILDING AUTOMATION SYSTEMS & ONGOING PERFORMANCE MONITORING New building automation systems provide a foundation for a number of synergistic energy efficiency opportunities, particularly for a high performance building with dynamic controls, multiple space uses, and multiple interacting systems. BAS allows for ongoing commissioning, sequence changes and system optimization throughout the operation of the building to ensure optimal performance. Complementing a modern BAS, the following technology applications would be highly opportunistic: o o o o Submetering – Submetering of heating, cooling, ventilation, lighting, plug loads, process loads is necessary to allow for accurate tracking of energy consumption, cost allocation of energy, and the prioritization of system improvements and controls optimization strategies. Fault Detection and Diagnostic Systems - Fault diagnostics is the next layer of control aimed at approaching net zero energy consumption for buildings. While the building automation system is capable of controlling equipment, data display, alarming and trending, it is not capable of detailed fault detection and troubleshooting. Fault detection and diagnostics software is capable of conducting custom detailed analysis on the data handled by the building automation system in order \ to detect opportunities for optimization and improvements Ongoing Commissioning - Ongoing commissioning of the building systems is the primary intent of the detection system. While commissioning and re-commissioning of systems is effective for instantaneous verification of correct system operation, fault detection systems continue to watch building systems long after start up and initial testing is complete. The combination of ongoing monitoring and custom analytics provides a platform for continued system optimization and a realtime view of the buildings energy consumption. Occupant Energy Dashboards - The energy dashboard gives the user and building occupants the opportunity to engage building systems and view in real time how conservation measures such as high efficiency lighting and HVAC systems save energy. These kinds of technologies begin to address the occupant behavioral side of energy management, and offers energy savings as well as educational opportunities for students and faculty. The Cadmus Group, Inc. 44 NYU-Poly Sustainability & Climate Action Plan Figure 14: SkySpark – a Web-based Fault Detection and Diagnostics Systems Software integrated with the Building Automation System It is estimated that a building thoughtfully designed to incorporate these kinds of high performance technologies and features will be able to achieve an overall energy use intensity of 26.6 kWh/sf. This represents a 40% reduction as compared to buildings with similar space types and square footage. The building assumptions for this estimate were: 160,000 gross SF, with 35% designated as laboratory space and 65% as classroom/office space. Savings from this kind of high performance design would be in the order of 5,300,000 kWh with an associated emissions reduction of approximately 1,200 mTCO2e. 4.1.14. Campus-Wide Phase 3 measures that are associated with the campus as a whole and not any one building include: P3.10 Campus On-Site Generation and Microgrid Management The NYU-Poly Microgrid Project proposes to utilize a highly efficient cogeneration system to produce electricity and thermal energy (hot water or steam, chilled water, and domestic hot water).23 This energy will replace electricity that would have come from the utility (Hess) and thermal energy produced using the University’s boilers. The net emissions produced by the Microgrid project are expected to be substantially below those associated with the current grid and existing thermal energy system configuration. The net emissions reduction is a result of two factors: 23 The gas turbine electric generation that is proposed for this project will potentially have a lower CO2- electricity emissions factor (i.e. cleaner electricity generation) than grid generation. In the case of NYU-Poly, which relies on the same grid mix of electricity as the rest of New York City, the city-wide grid emissions factor is very low because of a heavy reliance on hydroelectricity. The preliminary estimate on the potential capacity of the MicroGrid project, and the use of waste heat recovery was provided from Pareto Energy, Ltd. The subsequent calculation of net carbon emissions based on this estimate was performed by the Cadmus Group, Inc. The Cadmus Group, Inc. 45 NYU-Poly Sustainability & Climate Action Plan For this reason the preliminary estimate of net emissions from electricity generation only are higher for the Microgrid based generation. A more detailed study is necessary to evaluate exactly what electricity would be offset by the Microgrid. For example if the Microgrid were designed to offset peak-demand electricity while still relying on the grid for base loads, it is possible that there would be a net savings. The byproduct of natural gas combustion-driven electricity generation is a large amount of waste heat. The Microgrid project intends to capture and use this waste heat that would otherwise be unavailable from the grid. This waste heat will supply campus wide heating, cooling (absorption chillers require heat as part of its refrigeration cycle), domestic hot water heating, and heating for process loads such as steam generation for laboratories. It is this component of the Microgrid system that could potentially result in very large savings. The following table quantifies the various energy and heat generating services that the Microgrid will provide for the campus, and shows net emission reductions from the project. A negative number for net savings implies an increase in emissions.

Solar PV systems require a significant upfront investment, however the lifetime of solar panels is long and the ongoing maintenance is relatively minimal. Self-generation of electricity also protects the campus against escalating electricity prices from grid-purchased electricity in the future. Conservative estimates of available rooftop space show that there is sufficient space for up to 650 kW of solar capacity (after the construction of the Science & Engineering building). If installed, this would generate 805,219 kWh annually and result in an annual emissions reduction of 306 mTCO2e. 4.1.15. Combined Phase 3 summary The full implementation of all Phase 3 measures would result in a reduction of 19,095,000 kWh of energy on an annual basis and reduce emissions by 3,001 mTCO2e. This is equivalent to a 32% reduction of total projected campus emissions by the year 2030. Combined with Phase 1 and 2 measures, this would result in an overall reduction of 5,302 mTCO2e, equivalent to a 48% reduction from total projected 2030 emissions. The Cadmus Group, Inc. 46 NYU-Poly Sustainability & Climate Action Plan It is unrealistic to expect that NYU-Poly will be able to implement all of these very high capital measures. The purpose of the Phase 3 measures section is to present a list of possible measures which can be compared and evaluated against one another on the basis of their merits. A summary of the measures discussed in this section is shown in Table . The next step in this process is to identify the measures that have the greatest likelihood of being implemented and begin to explore opportunities for funding.

In the emissions projections shown in Figure 4,6 and 8, the annual emissions reductions shift slightly over time due to changes in emissions factors and campus growth.

Non-Building Scope 3 emissions are not required to be addressed by the PlaNYC Mayoral Challenge, and only a select portion of Scope 3 emissions are required to be addressed for the ACUPCC Climate Action Plan. These selected Scope 3 emissions (student and faculty commuting, directly financed air travel) represent only 14% of total emissions. It is for these reasons that the emission reduction measures primarily focused on building related measures. However looking at GHG emissions from a holistic perspective is good practice, and can lead to unexpected opportunities as well as greater student and faculty engagement. Select non-building related GHG emission reduction measures are discussed below. 4.1.16. Bicycle Network, Storage and Shower Facilities Total transportation emissions from NYU-Poly student, faculty and staff commuting were 883 MTCO2e in 2009, 11% of total campus emissions. This represents a percentage of emissions that is significantly lower than what is typical across US university campuses, and is primarily due to the location of NYU-Poly. In the heart of downtown Brooklyn, NYHU Poly is within walking distance of multiple subway lines, bus lines, and in proximity to the LIRR Atlantic terminal. The result of this is that approximately 90% of students, faculty and staff use public transit to commute to campus. Given this baseline, measures focused on increasing public transit ridership would result in minimal emissions reductions. Alternatively, it is proposed that NYU-Poly focus on increasing bicycle ridership and other forms of non-motorized transport. Bicycle ridership in NYC has grown substantially in the past five years, and is a very viable option in the highly dense urban The Cadmus Group, Inc. 48 NYU-Poly Sustainability & Climate Action Plan environment of downtown Brooklyn. In order to encourage this form of transportation, the following strategies are recommended: - Secure short term bicycle storage for visitors and occupants (e.g. exterior bicycle racks near entryways) - Secure long-term bicycle storage for students, faculty and staff (e.g. interior bicycle storage rooms with controlled access) - On-site showers with changing facilities accessible to students, faculty and staff Dedicated bicycle lanes that extend throughout the campus with no barriers (e.g., fences) , and that link up with a larger bicycle network in the neighborhood - Establish a bicycle maintenance program and/or route assistance program that can be managed by students and faculty. It should include services such as: coupons for yearly bicycle tune-ups; an onsite or nearby bicycle repair shop with repair training instruction; maps identifying bicycle routes to the project site, posted on the property in a location that is easily accessible to employees and customers. It is estimated that if bicycle ridership increased to 7% for the total campus population, 40 mTCO2e would be saved annually. This measure is built into the Phase 2 emissions projections in Figure 8. 4.1.17. Carbon Offsets Assuming the full implementation of all Phase 1, 2 &3 reduction measures, the anticipated campus-wide GHG emissions by 2029 would be 4,880 mTCO2e, a 48% reduction from the business-as-usual projections. While this represents a tremendous emissions savings, significantly more emissions would need to be reduced to reach climate neutrality, as per ACUPCC. If NYU-Poly does wish to pursue this goal, the most feasible way to reach climate neutrality after the implementation of all Phase 1, 2 and 3 measures would be through some type of carbon offset purchase. A carbon offset program could be established on campus that could accept open donations, and could be geared to offset particular types of campus carbon emissions (e.g. electricity, commuting, air travel), or fund particular GHG emission reduction projects (e.g. rainforest preservation). Some example carbon offset programs include: - Green Power (e.g. Renewable Energy Certificates, Utility Green Pricing Programs) - Energy Efficiency and Carbon Reduction Projects - Reforestation & Avoided Deforestation Projects A few widely recognized national and internationally recognized verification standards for these types of projects include: American Carbon Registry, Climate Action Reserve, Climate, Gold Standard, Social Carbon, Verified Carbon Standard. Any purchased carbon offsets should be verified by one of these standards. As an example, in order to net out the remaining 4,880 mTCO2e that would remain after full implementation of all campus reduction measures, the campus would have to purchase 17,296 MWh of renewable energy certificates or sponsor the planting of 64,845 trees in the rainforest25 (~162 acres) on an annual basis. The purchase of these carbon offsets is projected in the Phase 3 emissions trajectory in Figure 8. 25 http://www.carbonify.com/carbon-calculator.htm The Cadmus Group, Inc. 49 NYU-Poly Sustainability & Climate Action Plan Scope 1 emissions (NG) Scope 3 emissions (non-bldg) Phase 1&2 Reductions 18,000 PlaNYC Target 16,000 GHG emissions (MTCO2e) Scope 2 emissions (elec) Phase 1 Reductions Phase 1,2&3 Reductions Science & Engineering Bldg 14,000 Phase 1 Measures Implemented 12,000 Phase 2 Measures Implemented ACUPCC Climate Neutral Target Phase 3 Measures Timeframe 10,000 8,000 6,000 4,000 2,000 0 2007 2009 2011 2013 2015 2017 2019 2021 2023 2025 2027 2029 Figure 16: Phase 3: NYU-Poly GHG Emission Projections under (1) Business-as-Usual; (2) with Phase 1 Emissions Reductions; (3) with Phase 1 and 2 reductions; (4) Phase 1,2 & 3 reduction measures. The dotted black line shows the PlaNYC 30% reduction in carbon emissions intensity target, starting in the year 2018. This target is achieved by the implementation of Phase 1 and2 measures. The green line shows the projected emissions with full implementation of Phase 1, 2,&3 measures, which would achieve a 48% reduction of GHG emissions by the Year 2029 as compared to the business-as-usual trajectory. The dotted green line from the Year 2029 to 2030 represents the additional GHG emission savings that would result from the purchase of carbon offsets in order to achieve climate neutrality in 2030. The Cadmus Group, Inc. 50 NYU-Poly Sustainability & Climate Action Plan Plans to track and Report Emissions The above efforts will be implemented and continue to be refined as future versions of the greenhouse gas inventory unfold in order to account for and mitigate pollution sources. NYU-Poly will continue to track the emissions types outlined the baseline inventory and update the inventory on a regular basis as required by both the ACUPCC and PlaNYC Mayoral Challenge requirements, and will explore additional emissions types and sources to evaluate in order to capture the most accurate representation of the campus emissions footprint. In the event a new emissions source is found to increase NYU-Poly’s total metric tons of greenhouse gas emissions, additional reduction measures will be employed and the University will continue to pursue the ACUPCC climate neutrality goal. A new climate action plan will be generated based off of update inventories on a regular basis to ensure that NYU-Poly is progressing in line with the goals outlined in this original Climate Action Plan, is on track to reach the PlaNYC Mayoral Challenge target, and is reaching for the ACUPCC climate neutrality goal.
