When choosing new windows for your home, one of the key factors to consider is the solar heat gain coefficient (SHGC) rating. It measures how well a window can block heat from the sun. It is expressed as a number between zero and one, with lower numbers indicating better heat-blocking capabilities. But what is a good SHGC rating for your new windows? The answer depends on various factors, and this blog discusses each one.
Climate Zone
Your local climate plays a significant role in determining the ideal SHGC rating for your windows. In regions with mixed climates like Ohio, window experts recommend those with SHGC ratings between 0.32 and 0.42.
Energy Efficiency Goals
Your personal energy efficiency goals also matter. If you are committed to reducing your carbon footprint and want to maximize energy efficiency, you might opt for windows with a lower SHGC rating, even if you live in a cooler climate. However, keep in mind that these windows may reduce passive solar heating during the winter months.
Local Building Codes
Check your local building codes and energy efficiency standards. They may specify minimum SHGC requirements for windows in your area. Compliance with these codes is essential when replacing windows.
Window Placement
The orientation and placement of your windows also matter. South-facing windows receive more direct sunlight than north-facing ones. Consider different SHGC ratings for windows in various orientations to optimize energy efficiency.
Window Technology
Advancements in window technology, such as low-emissivity (Low-E) coatings and multiple glazing layers, can significantly impact a window’s SHGC rating. These technologies can help you balance solar heat gain and insulation.
