Review of ventilation strategy to ensure sufficient ventilation is provided. This strategy uses fresh air intakes (wall or window vents) and the installation of a ducted, continuously running, mechanical extract ventilation system with local controls to adjust speed settings. Windows can be opened for rapid purge ventilation.

Monitoring & feedback recommended: Yes

ADVANTAGES

Continuous operation maintains specified air flow and fresh air exchange at all material times. Can be used in buildings with unquantified air permeability. Central control, with minimum of two speeds.
