Analysis of the energy consumption rate of office buildings by the type of heat source equipments: Analysis on 2009 fiscal year of DECC survey data

In this study, we aimed to confirm whether it is possible to improve the accuracy of the estimation equations of energy consumption rate of office buildings. By the difference in the type of heat source equipment, we classified the DECC survey data of 2009 fiscal year into three categories: "the electrical type", "the fuel-based type with boiler" and "the fuel-based type without boiler". As a result, using the multiple regression analysis, we were able to obtain more accurate estimation equations than before except for summer fluctuation-load rate in the electrical type.
