Skylight / July 9, 2018 / Delphine Demers
It is recommended that the skylight size should never be more than five percent of the floor area in rooms with many windows and not more than fifteen percent of the rooms total floor area for spaces with very few windows. Skylights on north-facing roofs provide cool illumination while east-facing roofs provide maximum light and heat in the morning. West-facing skylights provide afternoon sunlight and heat. South-facing skylights provide more passive solar heat than any other location. Skylights are an excellent way to bring more natural light into your home. Just one skylight can dramatically transform your room by adding 30% more natural light than a window. This helps you save energy and makes your home warmer during the winter.
This heat gain can be minimized by installing your south-facing skylight in the shade of deciduous trees or adding a moving window covering. Skylights come in all shapes and sizes. Its size greatly affects the illumination level and temperature of the space below. As a rule of thumb the size of a skylight should never be more than 5% of the floor area in rooms with many windows; and no more than 15% of the rooms total floor area for spaces with few windows. Dept. of Energy. Glazing Like windows skylight manufacturers use different types of glazing to improve their energy efficiency. The glazing comes in three different forms. Plastic glazing - This type of glazing is usually inexpensive and less likely to break than other glazing materials.
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.
