What is Ventilation?
|
|
Ventilation is a process that either supplies or removes air from a space by natural or mechanical means. All air that is exhausted from a building must be replaced by outside air. Building ventilation is the process of bringing outdoor air into a building, circulating it, and later taking away it to the environment. The main purpose of ventilation is to provide suitable indoor air quality by thinning and removing pollutants from the indoor air. Building ventilation is achieved by natural or mechanical means, or by a combination of the two.

| Natural ventilation |
|
Natural ventilation is the use of differential air pressure that exists between the inside of a building relative to the outside of it, across the building surrounding, to ventilate a building. The air pressure difference is caused by natural forces such as wind and temperature. Air moves into and out of naturally ventilated buildings through windows, doors, vents and other openings integrated into the building design and via infiltration/exfiltration.
|
| Mechanical ventilation |
|
Mechanical ventilation is the use of mechanical air handling systems—commonly referred to as heating, ventilation, and air conditioning (HVAC) systems—to ventilate buildings. Most commercial buildings use mechanical ventilation, which is more controllable and responsive than natural ventilation in providing adequate indoor air quality. However, mechanical ventilation also can exacerbate infiltration/exfiltration, which can compromise indoor air quality.
