家庭における省エネルギー機器導入効果の世帯収入階級別評価

摘要

本研究では,世帯収入を考慮して世帯類型別に機器投资額を設定し,額内で有効な省エネルギー機器を導入した場合の効果について検討した.推計の結果,機器支出額の変化に対する1次エネルギー消費削減量の感度が世帯収入により異なることが示された.また，導入機器は住宅のエネルギー消費ゃコスト以外に，同時に導入される機器のランニングコスト削減効果によっても変化することが示された.%Residential energy use feedback has been considered an effective form of intervention to promote conservation behavior among households. The purpose of this paper is to investigate the long-term effect of residential energy use feedback with HEMS (home energy management system) and designed to examine the HEMS browsing behavior and to ensure negative effects that derive from "wear-out".In total, 463 households responded to a questionnaire survey that had been carried out at July 2013 and all the respondent lives in newly built detached house equipped with HEMS and roof-top PV. We found that wear-out effects had been occurred to some of the residents and follow-up services after HEMS installed would be important on keeping residents engaged in educated on ways to reduce energy use.
