Skylight / July 7, 2018 / Arnou Gabriaux
These are like Gods own television screens! Moreover skylights will usually bring in more light than windows and are a great alternative to artificial lighting. Skylights have been used in housing and other architecture from time immemorial and these can never go out of style. Very often skylights have been found in old churches. They add certain warmth and charm to the somber interiors. Skylights are used frequently in modern architecture as well and many modern malls hospitals restaurants and other large public places make use of skylights for natural daylight to light up common areas. When selected carefully and installed an energy-efficient skylight can help minimize heating cooling and lighting costs to very large extent.
For example the optimum slope for a south-facing skylight in Columbus Ohio at 40º North latitude is 45º to 55º. Every skylight has a "shaft" which governs how much light is admitted into the room below. If all four sides are flared then the light is spread over a wide area. If your skylight has a shaft with perpendicular sides the light is focused straight below. If your skylights shaft is flared on only one or two sides then the light is sprayed in the flared direction. Ventilation If you wish you can have a skylight which also provides ventilation as well as light to your room. This allows you to release the hot air which collects at your ceiling.
For one thing skylights are positioned in such a way that they are inaccessible unless they are operated by remote. Even in cases of motorized skylights which are easily manipulated there are still some disadvantages that are inherent to skylights that are not present or minimized in windows. Vertical windows lose less heat by convection when compared to skylights. Also since windows are generally protected by overhangs or shrubs they lose less heat by radiation. On the other hand skylights are directly exposed to the sky. Thus they lose more heat by radiation. Proper insulation can reduce this heat loss to a large extent. In the summer season skylights are more exposed to the direct heat of the sun than windows.
