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.
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. [1]
1972-1975: Prototype Roof Pond House. This solar house was built in 1972 as a prototype for the roof pond system of heating and cooling invented by Harold Hay. Several aspects distinguish the project: First documented 100 percent heated and cooled passive solar building. Only instrumented solar house in operation during the 1973 energy crisis.
Solar energy is clean and renewable. Solar architecture is designing buildings to use the sun's heat and light to maximum advantage and minimum disadvantage, and especially refers to harnessing solar power. It is related to the fields of optics, thermics, electronics and materials science. Both active and passive strategies are involved.
Passive solar heating relies on the design and structure of the house to collect heat. Passive solar building design must also consider the storage and distribution of heat, which may be accomplished passively, or use air ducting to draw heat actively to the foundation of the building for storage.
Heat in a solar thermal system is guided by five basic principles: heat gain; heat transfer; heat storage; heat transport; and heat insulation. [59] Here, heat is the measure of the amount of thermal energy an object contains and is determined by the temperature, mass and specific heat of the object.
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 ...
