Sustainability K-STATE DEPARTMENTAL ECOREP PROGRAM ECOREP UPDATE May 2012 TIP OF THE MONTH: How many printers is your office or department operating? Are they all necessary? Having an unnecessary amount of printers can contribute to office waste and energy consumption. Consider routing all office or department computers to one central printer to conserve energy and save on ink cartridge costs. Set up the communal printer in a central location in your office or department to encourage your co-workers to occasionally get away from their desks. FROM CASEY LAUER’S DESK What does it cost for each employee to have a refrigerator in his or her office? Approximately $54/yr per fridge in electricity costs. What does it cost to leave the computer monitor on all of the time? Leaving an LCD computer monitor on 24/7/365 = $28/yr in electricity costs. We probably have 20,000 computers plugged in on campus, both personal and work related. How much does one more degree of heat cost? Is it less costly to add a fan to circulate the heat rather than raising the temperature? This is a very complex question, one in which I made some assumptions to arrive at my answer. The cost of one degree of conditioned air (heat and/or cool) per day in each building is $6.80. The average building is 40,000 square feet. The cost of one degree of conditioned air (heat and/or cool) per day on campus is $373. It is less costly to circulate air with a fan, assuming the fan is turned off when the space is unoccupied. Is it better to maintain constant temperatures or to raise/lower the temperatures in offices? How much could we save by lowering the overnight and weekend temperatures by five degrees? Temperature setback is always more energy efficient than maintaining constant temperatures. Assuming a 40 hour workweek, an office building is only occupied for 24% of the time. The remaining time can be setback, and this normally results in a 12% savings over constant temperatures. We have setback capabilities in some buildings, but due to intensive and sensitive research, it becomes nearly impossible in some buildings. On average, if we set back every building on campus, we could save $400,000/yr, but this isn't practical. For office spaces and typical administrative buildings, a typical setback would result in about $5,500/yr in energy savings. Your EcoRep Awards Committee selected three awardees for the inaugural K-State Campus Sustainability Awards. Awardees were recognized for their outstanding achievement in promoting and advocating sustainability on the K-State campus and within the Manhattan community. K-State Dining Services, Lee Skabelund, associate professor of landscape architecture and regional and community planning, and Students for Environmental Action were honored for their influential work and dedication to sustainability at KSU Bike Day May 2 on Bosco Student Plaza.
