By combining detailed data on the residential window stock and housing stock of the US with state-of-the-art window and building energy simulation models, the authors calculate the energy lost through windows in the residential sector by region and fuel type and forecasts of the same for future residential window stocks. The authors then estimate the carbon emissions associated with supplying the resulting heating and cooling energy. The authors find that existing residential windows are responsible for 2.4 quads per year of electricity and fuel use and 200 MT(CO[sub 2]) per year of emissions, representing 3 percent of US energy consumption and 4 percent of US CO[sub 2] emissions. A complete change of the stock to the most cost effective, currently available, energy saving fenestration systems would reduce these figures to 0.8 quads and 74 MT(CO[sub 2]) per year. The authors also find that complete implementation of advanced technologies under development could turn these losses and emissions into savings. Considering only normal replacement and new installation of windows, energy use and attendant CO[sub 2] production associated with offsetting heating and cooling energy lost through residential windows could either remain at current levels or drop by 20 to 25 percent by the year 2012, depending on the blend of fenestration technologies sold. Induced retrofits could reduce the energy losses even faster.
