Green home designers turning to daylighting for an energy-saving light source (video)
Daylighting is one of the most efficient means of saving energy, as daylight can substitute for lighting, even energy-efficient lighting.
For building professionals and homeowners, daylighting provides an energy-efficient option for making a home more livable and comfortable. Daylighting, simply put, is designing a home to incorporate sunlight into the interior of the home, rather than trying to block it out. In addition to strategic use of windows and skylights, daylighting also incorporates tubular daylighting devices.
Designing for daylighting incorporates some basic principles, according to
Phanchalath Suriyothin, a member of the faculty in the Department of Architecture at Chulalongkorn University, who wrote a recent post about the benefits of daylighting.
"For interior design, quality daylighting can promote design pragmatism, enhancing functional efficiency as well as aesthetics. For example, windows that invite daylight provide views, create atmosphere by reducing interior monotony, and promote passive energy savings through attractive use of daylight. Accordingly, the design of window openings is very important. Window heights directly affect depth of luminosity. Large windows that receive direct sunlight should be avoided. Other design considerations include the choice of glass types for windowpanes, the size of openings, and the use of shading devices, among others."
Vista, Calif.-based Solatube offers daylighting products for residential and commercial buildings. Some products incorporate LED lighting to blend daylight and artificial light to provide illumination throughout the day and night while significantly cutting energy use.
