Reap the Benefits of South-Facing Windows Throughout the Year

Every homeowner should learn the basics of certain design concepts, particularly those geared towards making homes more energy-efficient. Some concepts include south-facing windows and passive heating. Here are a few things about them you may not know.


According to the National Institute of Building Sciences, passive solar heating involves the “collection of solar energy through properly-oriented, south-facing windows”. The Office of Energy Efficiency & Renewable Energy of the U.S. Department of Energy (DOE), meanwhile, recommends that, “If you’re planning a new passive solar home, a portion of the south side of your house must have an unobstructed ‘view’ of the sun.”

Make Them Work

Homes that have passive solar designs are better able to stay warm throughout fall and winter, and cool during the summer months. The ideal window orientation will allow your home to absorb enough sunlight while the climate is cooler and use that heat to warm your home. To prevent too much sunlight from making your home uncomfortably hot, it will help to have access to good options for replacement windows.

Reaping the Benefits

You can best experience the benefits of south-facing windows if they are built with High Performance™ Low-E4® glass. Different iterations of such windows are proven to be effective against solar heat gain even as they allow a good amount of sunlight into your home. Installation by professionals is also key to ensure that your windows will function as expected.

"Quality product, quality workmanship. Everyone I interacted with at Renewal by Andersen of SW Missouri had pride in their work from sales to financing to project oversight to installation. It must be a great company to work for because that shows in the professionalism of the staff. Best of all, they want happy customers and go out of their way to make sure that happens. Yes, I love my windows (but I knew I would--it's a great product). Friendly, helpful, easy financing, and yes--they pass costs on to the customer for this, but it meant that I was able to get the windows I wanted and needed for my creaky, lopsided old house. Couldn't be more pleased."

"The company representative who met with me initially was very direct, told me how the process would go, explained about why Anderson windows are of such good quality and how they stand by their products and their workmanship. My 3 windows arrived when they said they would, & the men who installed them were very professional, polite, & efficient. They showed me how the windows work and left the room as tidy as it was before they did the installation."

Good qualtity & if you didn't know that there were screens on the windows you would think they were missing. Very clear view. Great in this hot weather, the house stays cool."
