2. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   A roof pond passive solar system, sometimes called a solar roof, uses water stored on the roof to temper hot and cold internal temperatures, usually in desert environments. It typically is constructed of containers holding 6 to 12 in (150 to 300 mm) of water on a flat roof.

3. Trombe wall - Wikipedia

   en.wikipedia.org/wiki/Trombe_wall

   Roof ponds, as another passive solar heating strategy, do not work well with multistory buildings since only the top floor is in direct thermal contact with the roof. However, the Trombe walls can be the load-bearing structure of the buildings, so each floor's equator-facing facade can take the advantage of the Trombe wall system.

4. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   During the ventilation cycle, sunlight stores heat in the thermal mass and warms the air channel causing circulation through vents at the top and bottom of the wall. During the heating cycle the Trombe wall radiates stored heat. [11] Solar roof ponds for solar heating and cooling were developed by Harold Hay in the 1960s.

5. Solar chimney - Wikipedia

   en.wikipedia.org/wiki/Solar_chimney

   A solar chimney – often referred to as a thermal chimney – is a way of improving the natural ventilation of buildings by using convection of air heated by passive solar energy. A simple description of a solar chimney is that of a vertical shaft utilizing solar energy to enhance the natural stack ventilation through a building.

   Rooftop HVAC unit with view of fresh-air intake vent Ventilation duct with outlet diffuser vent. These are installed throughout a building to move air in or out of rooms. In the middle is a damper to open and close the vent to allow more or less air to enter the space. The control circuit in a household HVAC installation.
