Research on minimum ventilation rate and air change rate of residential buildings at home and abroad

Presents the current residential ventilation standards and regulations in 16 countries. Applies the ventilation standards to the local average living space and common residences in China respectively, and analyses the minimum ventilation rate and air change rate. The results show that ventilation standards in different countries are formulated based on various factors. Thus the minimum ventilation rates are different. The air change rate of 0.5 h-1 meets the ventilation requirements for the most of countries, but the values of a few countries are higher. The air change rate in China is close to average level compared to the other countries.
