Mechanical ventilation operates independently from weather conditions such as high or low winds. This makes it easier to maintain a consistent temperature, as well as control the direction of air flow throughout complex building spaces.
Mechanical ventilation can include a heat recovery system which retrieves part of the heat from extracted air before releasing it outside of the building. Supply air from the mechanical ventilation inlets is typically 16-19 degrees, even on a cold day. Mechanical ventilation uses either low pressure to force the extraction of indoor air, or high pressure to force air in.
Low pressure – removes indoor air (extraction)
High pressure – introduces outdoor air (inlet)
