Harnessing Passive Heating With Your Windows

If you are looking to renovate your home, consider incorporating large, south-facing windows. In doing so, you are harnessing solar power in your home. This is known as passive solar design, which uses the sun’s energy effectively without the aid of panels or other mechanical systems. In addition to windows, other building elements like walls and floors can help boost the efficient use of the sun’s heat.

Window Placement

The placement of your home’s windows plays a crucial role in achieving passive heating for your home. Living in a warmer climate means the largest windows are reserved for the north-facing part of the house to reduce heat gain during summer while letting sunlight indoors.

Conversely, large windows should be placed on the south-facing side so they can draw heat during the winter months. When the summer comes, shading in the form of awnings or trees prevents certain rooms from becoming saunas.

The Best Windows for Passive Heating

Proper window orientation shouldn’t be the only thing to consider when considering passive solar design. You should also take the window features into account. For south-facing windows, for instance, choose those with low emissivity (low-E) glass coatings. Plus, make sure they have the appropriate solar heat gain coefficient (SGHC) and U-factor ratings suitable for your local area.

Reviews

"We had a large picture window and two side windows replaced. Everyone from the person who took our order to the installers were top notch. We got exactly what we wanted. Granted, we had to wait a few months, just like you do for everything these days, but we were told that up front. The windows were well worth the wait. We've replaced windows before by going to home maintenance stores. Don't waste your money on those. Our Renewal by Andersen windows look great, they operate like a dream, and are worth every penny. Quality through and through."
