Skylight / July 7, 2018 / Arnou Gabriaux
Skylights are best suited to catch sunlight from the overhanging clouds. In addition to this skylight windows allow a deeper penetration of the suns light into the structure of the house in such a way that it is less obtrusive. Skylights also keep heating and cooling costs down. Skylights are your windows to the heaven. They can breathe drama into any living space. And they are all the rage these days. In such a scenario it is easy for people to forget important considerations while choosing skylights. Energy problems that influence windows operate just as strongly or even more so in skylights. For instance heat loss heat gains solar gains ventilation and water pooling affect skylight windows too.
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.
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.
