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.
Your ventilating skylight can be operated by one of three ways: Manual skylight controls - These are opened by your use of an extended rod to manually crank the skylight open. These are designed for ceilings of less than 15 feet. Electronic skylight controls - A simpler model of this type of control is wired to a wall mounted switch which opens and closes the skylight. More complex models are controlled by a special wall console of a wireless remote control. Automatic operating controls - With this type of control integrated heat sensors trigger the skylight to open when the interior heat reaches a preset temperature. Exterior sensors automatically close the unit when they sense moisture.
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.
