Skylight / July 12, 2018 / Odo Vaillancour
Skylights are best suited to catch sunlight from the overhanging clouds. In addition to this skylight windows allow a deeper penetration of the suns light into the structure of the house in such a way that it is less obtrusive. Skylights also keep heating and cooling costs down. Skylights are your windows to the heaven. They can breathe drama into any living space. And they are all the rage these days. In such a scenario it is easy for people to forget important considerations while choosing skylights. Energy problems that influence windows operate just as strongly or even more so in skylights. For instance heat loss heat gains solar gains ventilation and water pooling affect skylight windows too.
Before installing a skylight in your home you need to carefully evaluate what type of skylight will work best for you considering your specific requirements and how to install it in a way that it improves your homes energy efficiency. Its a sensible idea to evaluate the energy performance ratings of skylights based on the climate that you live in and the architectural design of your home. In the U.S. you can find labeled energy-efficient skylights which tell you the minimum energy performance rating criteria by climate. The physical dimensions of the skylight also greatly affect the lux level and temperature of the space it is being used for.
For one thing skylights are positioned in such a way that they are inaccessible unless they are operated by remote. Even in cases of motorized skylights which are easily manipulated there are still some disadvantages that are inherent to skylights that are not present or minimized in windows. Vertical windows lose less heat by convection when compared to skylights. Also since windows are generally protected by overhangs or shrubs they lose less heat by radiation. On the other hand skylights are directly exposed to the sky. Thus they lose more heat by radiation. Proper insulation can reduce this heat loss to a large extent. In the summer season skylights are more exposed to the direct heat of the sun than windows.
