Passive Heating: How To Maximize South-Facing Windows

You may not be aware of it, but If you have any south-facing windows in your house, you are actually helping your home’s overall energy-efficiency by utilizing an ingenious little trick that is favored by designers and replacement window installation companies known as passive solar design.

In this post, Renewal by Andersen® of Rapid City digs deeper into passive solar design and shares how you can use it to maximize your south-facing windows.

What is Passive Solar Design?

Passive solar design or climatic design refers to the use of the sun’s energy to help heat up or cool off your living space without the aid of any mechanical and electronic devices such as pumps, fans, and electrical controls. It does this by capturing the sun’s heat and releases it during periods when the sun is not up to help maintain a comfortable indoor temperature. 

It has two primary elements: south-facing glass and thermal mass to absorb, store and release heat. The larger your windows are, the more effective it is that’s why a picture window installation in your living room, for example, is a good way of taking advantage of passive solar. 

Passive Solar and Low-E Windows

To take full advantage of a south-facing window, contractors recommend using Low-E windows that have double or triple-panes to minimize infrared and ultraviolet light. Low-E or low emittance windows is a thin, colorless coating that is applied to the glass to improve its energy efficiency.

Low-E windows are fast becoming the standard for energy efficiency in windows and are effective in not just south-facing windows, but any window located in your home. A low-E window located on the north side of a building can minimize heat gain in the summer while still allowing plenty of light to shine through.
