Influential Factors on Energy Consumption for Cooling and Heating of Electrified Housing in Hiroshima Area

Abstract

In this paper, the electric power consumption of all electrified housing located in Hiroshima area was examined from the viewpoint of the relationships between the energy consumption for cooling and heating and the characteristics of houses and households. New separation method was developed to extract the electric power consumption for cooling and heating uses from the consumption for mixed uses, and the validity of the method was confirmed. Based on the consumption extracted, the actual condition of the consumption for heating and cooling was shown. Furthermore, to clarify the factors affecting heating and cooling uses, the Quantity Theory Cluster I was applied by using the characteristics of houses and households as explanatory variables.As the results, the partial correlation coefficient was higher in "structure", "age of householder" and "number of air conditioners" in cooling use, and "number of air conditioners" and "number of adults" in heating use. Therefore, it was clarified that the factors affecting the energy consumption for heating differed from them for cooling

Evaluation of potential for peak demand reduction of residential buildings by household appliances with demand response

“…Typical examples of the former type are results obtained by Mae et al 15 or by Ishida et al and Yasugi et al. [16][17][18] The data by Mae et be attributed to the recent increase in home meal replacements due to functional improvement of microwave ovens and changes in lifestyles. In addition, refrigerator and air conditioners in this dataset consume 30% or less power as compared to the previous studies.…”
