Discussion on occupancy schedule in China public building standard and a novel conception of typical occupancy data

Occupancy is one of the main factors affecting the building energy consumption. However, the occupancy data are simplified as occupancy density and occupancy schedule in China public building standard. This method is too simple to reflect the actual situation, which would influence the accuracy of building energy consumption calculation. Based on amounts of real occupancy data of different types of public buildings collected by mobile devices, applies the clustering method to extract the occupancy features of different buildings and compares with the occupancy description method in related building standards. Analyses the influence of the three factors of building, natural and social environment on occupancy data. Proposes a concept of typical occupancy data (TOD) and establishes a database of TOD.
