Skylight / July 11, 2018 / Nicolas Charlebois
Obviously skylights provide added day lighting and they may even offer ventilation. However heat gain and loss is also a consideration you should make. Many modern skylights feature sun tracking lenses or mirrored surfaces that provide light without heat loss or gain. Moreover whether a fixed skylight or similar alternative is better than a ventilated skylight is a question youll want to answer. Remember ventilating can help with temperature control but it is also important for preventing the buildup of moisture. Take some time to speak to your skylight or roofing professional so that you can be sure to choose the right skylight.
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.
Skylight windows are a wonderful addition to a home. Theres no doubt about it. But a lot depends on where exactly the house is located. Skylight windows are best suited for cool climates where the rays of the sun are not very harsh. Fortunately many places in the US have just this kind of weather. When used in such places skylight windows become the most important source of solar heating. And even when the sun is wobbly and there is little sunshine entering the room large skylight windows make the room look airy and bright dispelling the gloom. In areas where there is limited light and heat vertical windows are less efficient than large skylights because vertical sunlight is scant.
