resilient ventilation systems

Demand Control Ventilation strategy resilience is analysed through the envelope leakage distribution. Global building envelope leakage has great impact on energy consumption and targeted tightness values are systematically decreased in the several thermal regulations around the world. This leads to a more controlled ventilation system, but also to a more sensitive system to the leakage distribution. Considering fixed test cases with known entry data, two types of relative humidity based DCV strategy are analysed through their response to randomized envelope leakage distribution.
