Abstract: This paper presents an energy demand model of domestic hot water. The simulation model calculates daily behavior of household members and the daily behavior is converted to hot water use. The quantity of hot water accompanied by behavior was quantified by using measured consumption of city gas, water and electricity collected from approximately 200 households living in an apartment building. As hot water quantity cannot be derived directly from these data, city gas consumption was disaggregated into several end-uses under an assumption of hot water temperature. The behavior simulation and developed database enable to generate realistic hot water demand in terms of the time varying feature and the variety among households. This paper also presents a comparison between estimated result by the developed simulation model and the quantity of hot water quantified from the measurement. The result showed that the model is capable of generating realistic hot water demand with sufficient variety among households.
