Extract Ventilation Capacity

The design heat load of buildings is composed of maximal heat losses via ventilation, infiltration and transmission. Ventilation control possibilities can have an impact on these maximal simultaneous ventilation losses. An automated zonally and locally controlled residential mechanical extract ventilation system (rVST) was investigated with respect to the maximal occurring total extract rate during the heating period. The analysis was performed based on big field and simulated data of a smart connected ventilation system.
