In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.

The building is shaped like a fan and is covered in 4,600 square metres (50,000 sq ft) of solar panels. It was named the world's largest solar-powered office building in 2009. Although it is not yet completed, the Solar City Tower in Rio de Janeiro is another example of what solar architecture might look like in the future. It is a power plant ...
Passive solar building design and energy-efficient landscaping support the low-energy house in conservation and can integrate it into a neighborhood and environment. Following passive solar building techniques , where buildings are compact in shape to reduce surface area and principal windows oriented towards the equator (south in the Northern ...
Ideally, the site for the house should have a south westerly aspect and be protected from the north and east. It is not always possible to do this but there will usually be an opportunity to take advantage of the passive solar gain by having more glazing on either the front or the back of the building. Planting trees and creating windbreaks on ...
The Barra system is a passive solar building technology developed by Horazio Barra in Italy.It uses a collector wall to capture solar radiation in the form of heat. It also uses the thermosiphon effect to distribute the warmed air through channels incorporated into the reinforced concrete floors, warming the floors and hence the building.
The direct gain part delivers heat early in the day while the Trombe wall stores heat for the nighttime use. Moreover, unlike a full Trombe wall, the direct gain part allows views and the delight of winter sunshine. A building using Trombe wall as a passive solar strategy in Hopfgarten, Austria. A school with Trombe wall in Salta, Argentina.
In the United States, interest in passive solar building design was significantly stimulated by the 1973 oil crisis. [10] Dozens of pattern books were published in this period, including the Passive Solar Energy Book by Edward Mazria. [11] In 1977, the U.S. Department of Energy was created, and in 1978 Solar Energy Tax credits were provided.
