Natural ventilation potential analysis of rural residential buildings in China

This paper presents the method of natural ventilation potential analysis of rural residential buildings based on the relationship between the building external climate and the indoor acceptable thermal environment, and the basic theory of natural ventilation. The natural ventilation potential of rural buildings was calculated in ten different areas covered five climate areas in China. Finally, the different effective factors of natural ventilation potential such as acceptable indoor air temperature, building orientation and heat gain were discussed.
