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.
Passively adapted to the temperate-arid climate of southern California, the major design feature of the Solar Umbrella is a shading solar canopy. Rather than deflecting sunlight, this contemporary solar canopy uses 89 amorphous photovoltaic panels to transform the sunlight into usable energy, providing 95% of the residence's electricity. At the ...
Levine's Raven Run Solar House (1974) was the first to combine passive solar building design and active solar systems with earth tubes, an attached greenhouse, super insulation, "sundows," and a patented air collection system. Recognized as being ahead of its time, the house continues to be published today.
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 Canadian Passive House standard, administered by the Canadian Passive House Institute [28] In British Columbia the above programs align with the BC Energy Step Code, a provincial regulation to incentivize (or require) a level of energy efficiency in new construction beyond the base building code. The code was designed as a technical road ...
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.
A Trombe wall is a passive solar building design strategy that adopts the concept of indirect-gain, where sunlight first strikes a solar energy collection surface in contact with a thermal mass of air. The sunlight absorbed by the mass is converted to thermal energy (heat) and then transferred into the living space.
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 ...
