実測結果を用いた住宅電力消費の決定要因の分析

摘要

The purpose of this paper is to identify and compare factors affecting electricity demand of five residential households. We focused on the influence of the occupants' behavior as well as the possession, operation, shared use, specification of home appliance/equipment. Electricity consumption of the households were measured for two week at the lines of electric distribution board and disaggregated into those of all the appliances. Then, the influence of each factor was quantified by eliminating the difference in these factors among households. The most significant factor was the ownership of home appliance/equipment followed by the specification and operation of appliances, the occupants' behavior and finally shared use.%エネルギー消費の決定要因が住宅電力消費に与える影響を明らかにするため，所有機器，機器性能，共有利用，操作特性，生活時間の違いが住宅電力消費に与える影響を定量化した.図8に各決定要因による電力消費の変化量の世帯別積算値を示す.所有機器の違いでは，機器の追加により電力消費量が増加しており，機器性能と利用時間の影響が確認された.機器性能の違いでは，追加機能や稼働時間の違いによる差異が見られた.共有利用の違いでは，設置場所による影響が確認され，居間，台所に設置されている機器の影響が大きい.操作特性の違いでは，操作頻度の影響が確認された.行為別時間数の違いは世帯人数の違いを含んでおり，どの行為区分においても利用する照明機器の影響が大きい.
