ANALYSIS OF THE CONSCIOUSNESS BEHAVIOR OF INHABITANTS AND REDUCTION EFFECT OF ENERGY CONSUMPTION BY SETTING-UP THE ENERGY MANAGEMENT SYSTEM

-Study on the energy consumption of electrified housing in Hiroshima area-

Abstract

The electric energy consumption of 100 electrified housing in Hiroshima area was measured by energy management system as one kind of HEMS. In this paper, on the basis of the comparison between the annual energy consumption before and after setting-up of the system, the reduction effect of installation of the system was clarified. As the results, the rate of reduction compared with the consumption before setting-up was approximately 3%.
Furthermore, the factors of the reduction of energy consumption were examined. According to the comparison of three household groups classified by the consciousness and behavior of inhabitants, the reduction rate of the group which has already chosen the energy saving behavior before setting-up was larger than it of the group which tried to save the energy consumption after setting-up.
