Passive solar technologies include direct and indirect solar gain for space heating, solar water heating systems based on the thermosiphon, use of thermal mass and phase-change materials for slowing indoor air temperature swings, solar cookers, the solar chimney for enhancing natural ventilation, and earth sheltering.
Traditional heating and active cooling systems are absent, or their use is secondary. [ 1 ] [ 2 ] Low-energy buildings may be viewed as examples of sustainable architecture . Low-energy houses often have active and passive solar building design and components, which reduce the house's energy consumption and minimally impact the resident's ...
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.
Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process.

While passive solar techniques can reduce annual heating demand up to 25%, [19] specifically using a Trombe wall in building can reduce a building's energy consumption up to 30% in addition to being environmentally friendly. [20] Similarly, the energy heating savings of 16.36% can be achieved if a Trombe wall was added to the building envelope ...
