Passive Solar Design: Optimizing Energy-Efficient Windows

Looking for ways to cut your cooling costs? Installing energy-efficient custom windows can help, but they can only do so much on their own. If you want to maximize your potential energy savings, you’ll need to incorporate passive solar design into your home. Renewal by Andersen® of Austin shares some tips below.

How Does Passive Solar Design Work?

Homes with passive solar designs absorb heat from the sun coming from south-facing windows. A system of fans and blowers then distribute heat throughout the house, reducing the burden on your HVAC system.

How Passive Solar Design Can Help You 

Luckily, you don’t need to install additional fans and blowers to incorporate passive solar design into your home. All you need to take note of is the location of your energy-efficient windows. The south side of your home receives the most sunlight, so your new windows should be installed there. 

Some homeowners might wonder why they need to install energy-efficient windows when they can simply plant trees or hang blinds on the south side of their home. The reason is that with these options, you won’t be able to enjoy natural lighting, which can help lower your lighting costs, not to mention improve your mood. 

Energy-efficient windows let in natural light while blocking solar heat. The solar heat gain coefficient (SHGC) gives you an idea of the amount of solar heat a window can block. The lower the SHGC is, the less heat can pass through a window.
