Managing Energy Costs in Colleges and Universities Managing Energy Costs in Colleges and Universities Colleges and universities in the U.S. spend an average of $1.10 per square foot (ft2) on electricity and 18Â¢/ft2 on natural gas annually. In a typical college or university classroom building, lighting represents 31 percent and space heating accounts for 28 percent of total ener-gy use, making those systems the best targets for energy savings
(Data is calculated using a 2003 U.S. Energy Information Administration survey of com-mercial buildings.) Using average commercial energy prices of $0.10 per kWh and $0.98 per hundred cubic feet, the average cost of power per ft 2 for office build-ings is approximately $1.73 for electricity and $0.31 for natural gas.s a result, these are the best areas to target for energy savings. Quick Fixes Many office buildings can benefit from quick low-or no-cost energy-saving solutions such as turning things off, turning things down, and following a cleaning and maintenance schedule that keeps equipment running efficiently.
