Passivent’s fully glazed twin wall facade and biomass solid fuel heating system were specified for the Sorby House building. Passivent Aircool window ventilation inlets positioned within the glazed facade draw fresh air through the office spaces using variations in natural air pressure.

Integral acoustic attenuation modulates prevent outside noise from coming in. 25 suspended ceiling louvres further utilize natural air movement.

A passive stack is created between the twin walls of the facade and internal vertical ducts where used internal warm air rises, and is then exhausted via four Passivent Airstract terminals on the roof and 10 terminals above the facade.

The Passivent system functions with natural air movement and needs electricity only to facilitate the movement of the louvres.
