Abstract: In simulations of the energy demand of commercial buildings, assumptions regarding building operations are used to characterise the magnitude and temporal variation of the energy demand. However, the operating conditions of building stock are rarely available, preventing building stock and urban building energy models from simulating realistic time variations in energy demand. Based on this background, this paper presents a method for extracting an operation schedule from the time-series data of building electricity demand. The method consists of a demand disaggregation, parameterisation of operation conditions, and development of joint probability distributions for parameters that can be used to assign operation conditions to simulated buildings. This method was applied to a few thousand commercial buildings in six building groups located in Japan. The results demonstrate that the method is useful for capturing the variations in the operation conditions of buildings.
