Asheville NC Custom Builder Helps Homeowners Position Skylights

A variety of skylight shapes exist for sloping or flat roofs. Some skylight shafts exert nearly as much influence over the energy properties as the actual skylight itself. Sky lighting may take the form of general glazed areas such as atria, attached conservatories or sun spaces. In this form roof lights are less likely to be factory-manufactured items and more likely to be constructed on-site. Excellent day lighting is provided by skylights which have the potential to displace much artificial lighting, improving light quality, reducing heat generation and saving on energy costs. Under an unobstructed, overcast sky the amount of light, or luminance, from directly above (the zenith) is about three times as much as from the horizon.

A skylight can admit more than three times as much light as a vertical window of the same size. While this performance differential may be reduced in reality (ex. by a long shaft), in most situations a skylight has the potential to be a very effective day lighting device. Even under overcast conditions use of skylights can result in spaces that can be predominantly daylit with little supplementary artificial lighting required. Additional energy needed for space heating and cooling because of thermal movement through larger window areas will be minimized. The right size of skylight admits just enough light for the job and no more. Several methods exist for helping to decide on the size and spacing of skylights. Advantage Development Co.
