3. 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.

4. Ventilation (architecture) - Wikipedia

   en.wikipedia.org/wiki/Ventilation_(architecture)

   Mechanical ventilation is the intentional fan-driven flow of outdoor air into and/or out from a building. Mechanical ventilation systems may include supply fans (which push outdoor air into a building), exhaust [3] fans (which draw air out of a building and thereby cause equal ventilation flow into a building), or a combination of both (called ...

5. Ventilative cooling - Wikipedia

   en.wikipedia.org/wiki/Ventilative_cooling

   Ventilation is present in buildings mainly for air quality reasons. It can be used additionally to remove both excess heat gains, as well as increase the velocity of the air and thereby widen the thermal comfort range. [3] Ventilative cooling is assessed by long-term evaluation indices. [4] Ventilative cooling is dependent on the availability ...

6. Underfloor air distribution - Wikipedia

   en.wikipedia.org/wiki/Underfloor_air_distribution

   Underfloor air distribution (UFAD) is an air distribution strategy for providing ventilation and space conditioning in buildings as part of the design of a HVAC system. UFAD systems use an underfloor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air to supply outlets (usually floor ...

7. Heat recovery ventilation - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_ventilation

   Heat recovery systems typically recover about 60–95% of the heat in the exhaust air and have significantly improved the energy efficiency of buildings. [2] Energy recovery ventilation (ERV) is the energy recovery process in residential and commercial HVAC systems that exchanges the energy contained in normally exhausted air of a building or ...
