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.

Electricity-generating solar panels on roof. Orientation towards the Sun also means that active solar systems can be fitted, both solar water heating panels and electricity generating solar panels on the roofs, further adding to the free heat and electricity gained from the sun. [2]
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.
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 ...
A double envelope house is a passive solar house design which collects solar energy in a solarium and passively allows the warm air to circulate around the house between two sets of walls, a double building envelope. This design is from 1975 by Lee Porter Butler in the United States.
There are two types of solar water systems: active and passive. An active solar collector system can produce about 80 to 100 gallons of hot water per day. A passive system will have a lower capacity. [22] Active solar water system's efficiency is 35-80% while a passive system is 30-50%, making active solar systems more powerful. [23]
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.
