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.

"I just bought my first house. My patio sliding door was rotten. So, I needed it to replace it. Renewal by Anderson of Southern Missouri listened to what I wanted and delivered it. They did a fantastic job of installing and cleaning up afterwards. They did it even in freezing rain that day I was scheduled to have it replaced. They even had a follow-up to check things out and do the touch ups. I'm amazed at there work. Great job Renewal by Anderson."

"On Feb 1,2024 my husband and I selected Renewel by Andersen for windows for our entire house. It made our house more beautiful with the picture windows. Made the outside more attractive, and on the inside. We did 14 windows. We had 4 men come to do the job in 1 day And they were very friendly, efficient,fast and cleaned up inside and outside perfectly. And most importantly we noticed the heating furnace runs less,therefore saving us money on our gas bill. We live in SW Missouri. We recommend anyone who wants to replace windows in their home to pick Renewal by Andersen. Sincerely, Darius and Nancy Durman"
