Residential end-use energy simulation at city scale

This paper describes a simulation model for predicting end-use energy consumption in residential sectors of a city or region. In this model, the annual energy consumption of a dwelling is simulated from the occupants’ schedule of living activities, weather data and energy efficiencies of appliances and dwellings. By summing up the simulation results for various household categories, total energy consumption for the residential sector in a region can be estimated. In this paper, energy consumption for Osaka City is simulated. The result is compared with statistical data. The effects of energy efficiency standards and urban heat island phenomena are examined.
