Actual and Estimated Energy Savings Comparison for Deep Energy Retrofits in the Pacific Northwest

Description: Seven homes from the Pacific Northwest were selected to evaluate the differences between estimated and actual energy savings achieved from deep energy retrofits. The energy savings resulting from these retrofits were estimated, using energy modeling software, to save at least 30% on a whole-house basis. The modeled pre-retrofit energy use was trued against monthly utility bills. After the retrofits were completed, each of the homes was extensively monitored, with the exception of one home which… more

Mobile home weatherization measures: A study of their effectiveness

Description: The Solar Energy Research Institute (SERI) was funded by the Department of Energy's Office of Buildings and Community Systems (DOE OBCS) in FY 1987 and 1988 to investigate cost effective ways to weatherize mobile homes constructed prior to the enactment of HUD Thermal Standards in 1976. In FY 1987 SERI studied the effectiveness of a variety of infiltration-reducing retrofits by monitoring 20 units in the field before, during, and after applications of air tightening measures. In FY 1988 we bega… more

NREL Furthers U.S. Marine Corps Air Station Miramar's Move Toward Net Zero Energy (Fact Sheet)

Description: A 2008 report from the Defense Science Board concluded that critical missions at military bases are facing unacceptable risks from extended power losses. A first step in addressing this concern is to establish military bases that can produce as much energy as they use over the course of a year, a concept known as a "net zero energy installation" (NZEI). The National Renewable Energy Laboratory (NREL) has helped the U.S. Marine Corps Air Station (MCAS) Miramar, located north of San Diego, Califo… more
