If all of the original windows and doors in an average older home were replaced by ENERGY STAR qualified windows and doors, the household energy consumption would be reduced by about 7 percent. If ENERGY STAR qualified windows, doors and skylights where installed in an average new home instead of conventional products, energy consumption would be reduced by about 16 percent. With ENERGY STAR qualified windows, the interior glass stays warmer, so you can enjoy your window seat even when the temperature outside dips well below freezing. Most ENERGY STAR qualified windows reduce the “heat gain” into your home more than typical windows do, without reducing the visible light. You get the light you need without the uncomfortable heat during those hot summer days.
