What criteria does the ENERGY STAR Program use for Window and Door Performance? |
||
| The first energy performance rating is the U-Factor. U-Factor measures heat transfer through a window and tells you how well the window insulates. The lower the U-factor, the better the window insulates. During winter months, the lower a windows’ overall U-factor, the less heat you will lose through that window, and the less energy you will use to heat your home. The second performance rating is Solar Heat Gain Coefficient. This measures how much solar heat is admitted into your home through the window, and tells you how well the window blocks heat caused by sunlight. The lower the SHGC, the better the window is at blocking heat. During summer months, a lower SHGC means less solar radiation is admitted through your windows, keeping your home cooler, and saving you money on running your air conditioner.
