Skylight / July 12, 2018 / Odo Vaillancour
A skylight is like a window which has been placed in your roof. It has a frame specially designed to withstand rain and prevent leakage from rain and snow. To maximize a skylights use of natural light to illuminate a room or its passive solar heating potential you will want to take into consideration how a skylight is positioned. Facing north your skylight will provide fairly constant illumination but will not provide a lot of heat. Facing east it will provide the maximum amount of light and solar heat gain in the morning. Facing west your skylight provides afternoon sunlight as well as heat gain. A skylight facing south provides the greatest potential for winter passive solar heat gain than any other location but will often allow unwanted heat gain in the summer.
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.
The structure of the house is another deciding factor. If there are beams pillars or pipes in the way the skylight on the roof may not get the right amount of visibility. Making structural changes is not an affordable option in most cases. So it is better to evaluate the room before you place skylights on the roof. In most cases skylights should be built into the house at the time of drawing the design of the house. In case skylights are introduced at a later point of time care must be taken to ensure that they are placed correctly and installed properly. Skylights are overhead windows often in a roof that allow sunlight to filter inside any enclosed area; they are a great natural light option to artificial lighting solutions during the daytime.
