2. Whole-house fan - Wikipedia

   en.wikipedia.org/wiki/Whole-house_fan

   A typical whole-house fan, with louvers closed when not operating. A whole house fan is a type of fan, commonly venting into a building's attic, designed to circulate air in an entire house or other building. The fan removes hot air from the building and draws in cooler outdoor air through windows and other openings.

3. Trickle vent - Wikipedia

   en.wikipedia.org/wiki/Trickle_vent

   The US Standard ASHRAE 62.1-2007: Ventilation for Acceptable Indoor Air Quality, only requires 4% of net floor area to be operable. This creates the potential for increased energy consumption where natural ventilation is provided by operable windows where supplemental air conditioning is provided, in addition to generally poor control over ventilation rates during hot summer or cold winter ...

4. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   Ventilation on the downdraught system, by impulsion, or the 'plenum' principle, applied to schoolrooms (1899) Natural ventilation is the ventilation of a building with outside air without using fans or other mechanical systems. It can be via operable windows, louvers, or trickle vents when spaces are small and the architecture permits.

5. 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 ...

6. Room air distribution - Wikipedia

   en.wikipedia.org/wiki/Room_air_distribution

   Displacement ventilation systems supply air directly to the occupied zone.The air is supplied at low velocities to cause minimal induction and mixing. This system is used for ventilation and cooling of large high spaces, such as auditorium and atria, where energy may be saved if only the occupied zone is treated rather than trying to control the conditions in the entire space.

7. Underfloor air distribution - Wikipedia

   en.wikipedia.org/wiki/Underfloor_air_distribution

   The most common UFAD configuration consists of a central air handling unit delivering air through a pressurized plenum and into the space through floor diffusers. Other approaches may incorporate fan powered terminal units at the outlets, underfloor ducts, desktop vents or connections to Personal Environmental Control Systems. [8]
