The establishment of a social system that is resilient to disasters and environmentally conscious is a pressing requirement since the occurrence of the Great East Japan Earthquake. This study deals with the evaluation of the energy-saving, self-supporting power supply of a photovoltaic generation system (with a storage battery) in a medium-sized office building located in Miyako city, Iwate Prefecture. In a previous study, the reduction in required power was evaluated and general power consumption characteristics were determined using electric power consumption data. In addition, photovoltaic power generation was measured annually. In this study, the power consumption required in an emergency is estimated from the relationship between the power generation and outside air temperature using the measured data. Therefore, the functionality of the disaster prevention center can be gauged by calculating the electric power self-support rate over three days (72 h) after a disaster.
