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.
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.
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.
Tubular skylights An alternative to the conventional skylight which looks like a window in your roof is the tubular skylight. The tubular skylight is a roof-mounted dome which collects natural light and delivers it to the room below. It is less expensive than the conventional skylight because it is designed to fit between roof and ceiling framing eliminating the need for structural modifications. You will commonly see these used in bathrooms hallways and closets but they can be used in any room of your house. The average tubular skylight ranges in size from 10 - 21 inches in diameter which lights a 100-600 square foot interior space.
