Abstract
Occupancy patterns in residential buildings and profiles with family information are essential for the energy system design and optimization, for the electricity demand responses and management of buildings, and for constructing household energy efficiency policies. To address the shortcomings of current research, this study conducted a national-wide survey in China with a valid sample of 8,190 urban households representing 19,352 individuals. On this basis, a novel approach was generated and conducted to identify the occupancy patterns in residential buildings and describe profiles of typical families in this research. As a result, typical residential occupancy profiles in urban China were obtained by analyzing distribution of the duration of residential occupation and the sequence of occupancy patterns in this research. Meanwhile, detailed results of four typical occupancy patterns with demographic characteristics during workdays, and five patterns during weekends were described for further research and application.
