The Research of Building Air Permeability Based on Building Structural Tightness

Abstract:

The building air permeability plays a major role in both building energy performance and indoor air quality. The performance of structural tightness is set as an evaluation index of building air permeability, which is employed to analyze the relationship among building air permeability, building construction and window/door air permeability. Based on some assumptions, the coefficient of building structural tightness is established to summarize the influential factors on building air permeability, and the theory method is provided to improve the building air permeability. A model of air permeability for a small room is taken as an example. The results indicate that the building structural tightness coefficient is available to analyze the building air permeability.
