Cross-flow and Passive Stack Ventilation

Passive stack ventilation (PSV) is the most effective natural ventilation strategy as it uses a combination of cross ventilation, buoyancy (warm air rising) and the venturi (wind passing over the terminals causing suction) effect.

Use of Passivent Airstract Terminals can ventilate twice the depth into a building compared to single sided ventilation strategies and provides effective night cooling as internal and external temperatures have a higher variance at night increasing convection.

Combining Airstract Terminals with Aircool façade ventilators also allows fresh incoming air to be drawn through the occupied space from the façade.

This cross-flow strategy allows ventilation of deep plan spaces and effective distribution of fresh air.
