2. 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 ...

3. Solar chimney - Wikipedia

   en.wikipedia.org/wiki/Solar_chimney

   By integrating the attic space with a solar chimney, the hot air in the attic can be put to work. It can help the convection in the chimney, improving ventilation. [4] The use of a solar chimney may benefit natural ventilation and passive cooling strategies of buildings thus help reduce energy use, CO 2 emissions and pollution in general ...

4. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   A solar chimney (or thermal chimney) is a passive solar ventilation system composed of a hollow thermal mass connecting the interior and exterior of a building. As the chimney warms, the air inside is heated causing an updraft that pulls air through the building. These systems have been in use since Roman times and remain common in the Middle East.

5. Solar air conditioning - Wikipedia

   en.wikipedia.org/wiki/Solar_air_conditioning

   A solar chimney or photovoltaic-powered fan can be used to exhaust undesired heat and draw in cooler, dehumidified air that has passed by ambient Earth temperature surfaces. Control of humidity and condensation are important design issues.

7. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   Distribution of heat to the building can be accomplished through ceiling and floor level vents, windows, doors, or fans. In a common design, thermal mass wall situated on the back of the sunspace adjacent to the living space will function like an indirect-gain thermal mass wall. Solar energy entering the sunspace is retained in the thermal mass.
