Abstract: The authors have been developing a bottom-up type residential energy end-use simulation model, which simulates the residential electricity demand in 5-min increments. The purpose of this paper is to validate the model by using measured electricity consumption data. The model was validated according to the procedure for simulating cooling or heating energy consumption by using the measured electricity consumption data of room air conditioners (RACs) and occupants' presence schedule data which was extracted from measured data from distribution boards in 144 households. The model input was set according to a simulated result to validate, and the result was compared with the measured data in order to validate each step of simulation mentioned above. First, we validated heating or cooling load calculation and energy consumption simulation. As the results, this model underestimates heating load and electricity consumption in winter and overestimates the cooling load and the electricity consumption in summer. Then, we validated the determination of the RAC operational state. The results suggest that state transition probabilities determining the RAC on/off operational state should be reconsidered.
