Passive solar - Wikipedia, the free encyclopedia |
 | | Passive solar is a term referring to those technologies that can be employed to convert natural sunlight into usable heat, to cause air-movement for ventilation or cooling, or to store the heat for future use, without the use of electrical or mechanical equipment. |
 | | Passive solar technologies used domestically include the use of direct solar gain, solar space heating, those solar hot water systems based on the thermosiphon, thermal mass, the Trombe wall, solar cookers, the solar chimney, and earth sheltering. |
 | | For these reasons, passive solar technologies (together with energy conservation measures) should be considered before active solar technologies. |
