Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used for purposes of thermal comfort or dehumidification when the introduction of outside air will help to achieve desired indoor psychrometric conditions.
Ventilation should be considered for its relationship to “venting” for appliances and combustion equipment such as water heaters, furnaces, boilers, and wood stoves. Most importantly, the design of building ventilation must be careful to avoid the backdraft of combustion products from “naturally vented” appliances into the occupied space. This issue is of greater importance in new buildings with more airtight envelopes. To avoid the hazard, many modern combustion appliances utilize “direct venting” which draws combustion air directly from outdoors, instead of from the indoor environment.
