2. 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.

3. Attic fan - Wikipedia

   en.wikipedia.org/wiki/Attic_fan

   An attic fan installed underneath a roof. A powered attic ventilator, or attic fan, is a ventilation fan that regulates the heat level of a building's attic by exhausting hot air. A thermostat is used to automatically turn the fan off and on, while sometimes a manual switch is used. An attic fan can be gable mounted or roof mounted. Additional ...

4. Solar heat collector and radiator for building roof - Wikipedia

   en.wikipedia.org/wiki/Solar_heat_collector_and...

   A solar heat collector and radiator is a heat collecting and heat radiating roof structure, designed for building roofs specifically. It was built to be used in conjunction with solar energy and uses a system of air circulation for increased efficiency. [ 1 ]

5. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   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.

6. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   The SEGS is a collection of nine plants with a total capacity of 354 MW and has been the world's largest solar power plant, both thermal and non-thermal, for many years. A newer plant is Nevada Solar One plant with a capacity of 64 MW. The 150 MW Andasol solar power stations are in Spain with each site having a capacity of 50 MW. Note however ...

7. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   Electric fans used for ventilation may be powered by solar panels instead of mains current. This is an attractive option because once the capital costs of the solar panel have been covered, the resulting electricity is free. If ventilation needs are greatest during sunny weather, a solar-powered fan can be suitable.
