Analysis of Building Hybrid Ventilation Efficiency in Different Climate Regions of China
Hybrid ventilation has significant advantages in building energy-saving. We discussed the potential and influencing factors of the rational use of building hybrid ventilation systems in three typical cities, located in three different climate regions of China. We used the Adapted Comfort Standard (ACS) model and Energyplus software to analyze the hybrid ventilation efficiency. This method combines the advantages of Degree-Hours Method and Heat Balance Method, and also takes into account the wind-driven and buoyancy-driven models. Results shows that the natural ventilation potential (NVP) utilization hours of high thermal insulation buildings with temperature control ventilation can be up to 5080h in Beijing, 6195h in Nanjing and 6726h in Guangzhou, accounting for 58.0%, 70.7% and 76.8% of the full year respectively. It means that the rational use of hybrid ventilation and ventilation mode can significantly reduce building energy consumption in summer.
