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 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 ...
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.
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.
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]
Passive solar heating — uses large window areas, appropriately orientated to the sun, to absorb solar energy directly for space heating. In a retrofit situation this approach may need significant building remodelling to enlarge or reorient windows, although a conservatory or sunspace may be an easier add-on alternative. Passive solar heating ...
