According to the U.S. Department of Energy, solar heat gain coefficient (aka Solar Heat Gain or SHGC) is:
“The fraction of solar radiation admitted through a window, door, or skylight – either transmitted directly and/or absorbed, and subsequently released as heat inside a home. The lower the SHGC, the less solar heat it transmits and the greater its shading ability. A product with a high SHGC rating is more effective at collecting solar heat during the winter. A product with a low SHGC rating is more effective at reducing cooling loads during the summer by blocking heat gain from the sun. Your home’s climate, orientation, and external shading will determine the optimal SHGC for a particular window, door, or skylight.”
If you’re concerned about solar heat gain, remember, you have options. You can install windows, skylights, and shade structures to help protect your home from the sun. In fact, awnings, patio covers, and drop curtains are excellent shade structures you can install on your home or business to help lower solar heat gain.
- Awnings can reduce solar heat gain in the summer by up to 65% on south-facing windows, 77% on west-facing windows.
- Awnings can be designed to shade one window or an entire side of the home.
- Light colored awning fabrics reflect more sunlight.
- Using retractable or adjustable awnings allows for versatility; you can roll up your awning in the winter and extend it in the summer.
