It’s beneficial to learn more about your home’s energy efficiency. So in this post, let us learn about SHGC and how it affects your home’s energy performance. One of the area's most trusted door replacement companies Abby Windows discusses how you can measure SHGC and what the number means.

What Is Solar Heat Gain Coefficient?

Solar Heat Gain Coefficient or SHGC is a standard that measures how your window efficiently blocks heat from the sun. For starters, energy-efficient windows equipped with SHGC values reduce your home’s energy consumption. It acts as a barrier that shields the heat, preventing the temperature from increasing inside. The SHGC is one of your window’s insulation agents, it helps maintain your home’s conditioned temperature. Most energy-efficient windows nowadays are equipped with glasses that have SHGC values. 

How Is SHGC Rating Measured?

The SHGC value is represented by a number between 0 and 1. A low rating is preferable because it means that less solar heat is transmitted into your home. Ideally, your home should have an SHGC rating of 0.25 or less. Energy-efficient windows and new entry doors influence your home’s SHGC rating. So to improve your SHGC rating and increase your home’s energy efficiency, invest in energy-saving windows.

For a bit of background, the National Fenestration Rating Council or NFRC began testing window products and issuing SHGC ratings in 1993. The only independent energy rating and labeling system is managed by the NFRC. SHGC ratings are used by the US Department of Energy and the EPA to evaluate the energy efficiency of windows for product certification and federal incentive and rebate programs.
