ANALYSIS ON ENERGY CONSUMPTION FOR COMMON USE SPACE OF APARTMENT HOUSES CONSIDERING THEIR ATTRIBUTES

This study aims to found the basic data for promoting energy conservation policies by assessing the energy consumption in common space of apartment block. We investigated the actual electricity consumption in common use space of apartment houses. The data of electricity usage in common use space was collected from 1,345 apartment blocks (623,022 houses). We classified the apartment blocks by 1) year when administration had started, 2) number of floors, 3) number of houses, 4) water supply method and 5) number of elevators, in order to analyze the influences of those attributes on the electricity consumption. As a result, it became clear that the specific energy consumption of the apartment block differs significantly in the range from 42 kWh/year/house to 2,272 kWh/year/house, depending upon the abovementioned attributes.
