Solar heat gain coefficient (SHGC) ratings refer to the amount of solar energy transmitted through your windows, which can impact the energy efficiency in your home. Depending on where you live, you either need low or high SHGC ratings to maintain a comfortable indoor temperature.
To help you find the best window for your home, we discuss how SHGC ratings vary by location.
In Colder Climates
In colder regions, windows with a high SHGC rating are the better choice because the Northern regions are generally heating-dominated. Windows with an SHGC rating of about 0.30 up to 0.60 ensure your home can maximize solar heat. Since they help warm your home naturally, these windows can reduce the demand for your heating system and allow you to save on energy costs.
In Warmer Climates
If you live in warmer areas, choose windows with a lower SHGC rating. It’s important that homes in this type of climate are cool to ensure comfortable temperatures all day. If you live in the Southern regions, make sure to buy windows with an SHGC rating of less than 0.27. You can also consult a professional window contractor to guide you through your selection process.
In Mixed Climates
Homes located in the South Central region use both heating and cooling systems. Therefore, the SHGC ratings for windows and skylights in these places are usually kept under 0.30. However, in areas where heating is used extensively for certain periods of the year, a lower SHGC rating is needed to reduce solar heat gain. To determine which windows are best suited for your home, you can compare your cooling and heating costs.
