What Energy Star Rated Windows Actually Do

Energy Star performance is mostly about daily comfort. The benefits are not flashy, but they are noticeable, fewer hot spots, fewer cold corners, and less strain on heating and cooling equipment.

U-factor measures how well the window slows heat loss, while SHGC, or solar heat gain coefficient, shows how much solar heat passes through the glass. Those ratings matter in Tennessee because you want a window that resists heat when the sun is harsh, but still helps the house hold warmth during colder months.

New windows can lower heating and cooling waste, but the payoff depends on the age of the old windows, the size of the house, the quality of installation, and how much sun the home gets.
