EPAct 2005

While the debate rages on concerning the reason energy efficiency is the most important challenge of our day (whether a response to the economic, political-social, or man-made climate change), most people agree that reducing energy consumption has a broad range of benefits. The following illustrates the gap between the need for more energy efficient commercial buildings and the lack of acceptance of these measures:

  • According to the U.S. Department of Energy (DOE), lighting represents 40% of the average commercial building’s electric bill, followed by motors/HVAC at 40% combined and other equipment at 20%, and
  • According to the U.S. Environmental Protection Agency (EPA), commercial buildings account for 18 percent of total U.S. energy consumption and contribute an estimated 15 percent of U.S. greenhouse gas emissions, and
  • According to the EPA, energy consumption represents 30 percent of a typical commercial office building’s operating costs, making it the single largest controllable cost of operations, and
  • According to the DOE, only 20% of existing commercial buildings feature some degree of upgraded lighting technology while 80% continue to operate lighting systems installed before 1986, and
  • According to EPA estimates, the 2,500 buildings that have earned the ENERGY STAR label for energy efficiency through 2005 save a combined $350 million on their energy bills, and
  • According to the Energy Cost Savings Council (ECSC), energy-efficient lighting projects generate an average 45% return on investment …
