Heat from the SunMany solar heating experts will explain that one of the best ways to supplement the heat in a home is to position the structure to take advantage of the suns rays in the winter and to have this solar energy deflected in the summer. Now this might sound like an oxymoron but this is part and parcel of making the home more efficient. In the winter the windows are positioned to take in the suns heat which is then stored in the materials that make up the interior of the house. When summer comes the same angle of the windows prevents excess sun from entering the dwelling thus keep air conditioning bills down.

A certain amount of energy will heat the glass or be deflected because glass is not entirely transparent. The heat from the inside surfaces is given back into the room as long waves. This is known as the Greenhouse Effect because the heat stays in the building just as it does in a greenhouse. Having more than one pane of glass in the windows has an effect on how much sunlight passes thorough it. For example, a single pane lets in approximately 85% of light, double-pane glass around 75% and triple-pane will allow between 62-65% of the light to come through. If the sun is perpendicular to the window this increases the flow of light because the light does not travel through the glass at an angle. Figuring out the times when the sun is low (winter) and high (summer) can be instrumental in where to place your windows.1.
