This study presents a new method to summarize typical behavior patterns in residential buildings in China regarding air-conditioning use. A large-scale questionnaire survey was designed and conducted to get behavior patterns, which were then used in energy simulation. Based on the energy consumption, the behavior patterns were classified into categories and a typical pattern was extracted from each category. Finally, the typical behavior patterns were validated by the distribution testing of building energy consumption. These typical behavior patterns could be used to estimate the energy consumption with different composition of occupants and evaluate the energy saving potential of different technologies.
