Improper window use in office buildings: findings from a longitudinal study in Beijing, China

Occupants’ window behavior influences the performance of buildings significantly. A good window usage can provide comfortable indoor environment, but improper window usage may result in bad indoor environment and may also cause energy waste. This paper identifies improper window usage based on year-long date collected from an office building in Beijing, China. The findings from this study provide evidence that occupants’ window behavior in real buildings is needed to be improved in order to promote the building performance.
