MEASURE: Passive stack ventilation with demand control ventilation

Review of natural ventilation strategy to ensure sufficient ventilation is provided. This strategy uses either air pressure or temperature difference to draw in fresh air (at wall or window vents) and extract stale air to the outside (through passively operated extract terminals located in wet rooms). Demand Control Ventilation (DCV) adds a method of control of the ventilation system by demand factors (e.g. humidity, occupancy, presence of VOCs) as required by the specific use of the space. Windows can be opened for rapid purge ventilation

Monitoring & feedback recommended: Yes

ADVANTAGES

Simplicity; no energy in-use; silent operation; air flow maintained at adequate levels when it is needed but possible to reduce air flow when not required. This results in energy saving without compromising the air quality
