Abstract: The present study attempts to demonstrate the effectiveness of a bottom-up-type simulation model in designing or evaluating an energy/greenhouse gas (GHG) reduction policy in the residential sector. The model considers a diversity of factors such as the number of family members, the climate condition, the insulation level of the building, and the dissemination ratio and energy efficiency of appliances. The accuracy of the simulated energy consumption of the Japanese residential sector in fiscal year (FY) 2013 is verified. We estimate the GHG reduction effects for fiscal year (FY) 2030 by the most recent Japanese energy efficiency measures for the residential sector. As a result, the importance of selecting appropriate high efficiency water heaters by the policy is clarified.
