With well-designed south-facing windows, you can use the heat from the sun to warm your indoor spaces, helping you save on your heating costs. You can also add some upgrades to your existing structure to reduce your heating costs in winter and keep your interior cooler in summer.
Here’s how passive heating can help you maximize your south-facing windows.
Benefits of Passive Solar Design
Let’s say you have already recouped your initial costs for window replacement through energy savings. The good thing is that you can continue to save money through passive heating since your south-facing windows are a good source of heating for your home. Furthermore, with larger windows, brighter interiors and open floor plans, you can make your home feel bigger and more comfortable.
Passive solar design also diminishes mechanical noises and keeps your home comfortable even when the power is out. And since solar power is clean and a natural energy source, you’re also reducing your carbon footprint.
How to Maximize South-Facing Windows
In warm areas, the largest windows should be placed on the north side to reduce heat gain in summer while ensuring an ample amount of natural light. If you live in an area with a cold climate, your large insulating windows should be on the southern part of your home. They will bring more heat to your property during winter and can be easily shaded with trees or other window coverings in the warmer months.
As advised by the U.S. Department of Energy, consider installing double-pane windows in the southern part of your house. Your window glasses should have a solar heat gain coefficient (SHGC) of at least 0.6, a U-factor of no more than 0.35 and a high visible light transmittance. By regularly cleaning your windows, you can maximize the natural light and reduce the need for artificial lighting.
