助成制度を利用した既存住宅の省エネルギー改修による一次エネルギー削減効果に関する評価

抄録

In this study, several energy retrofit subsidy systems offered by local governments in Japan are investigated. Using the results, subsidy systems are classified into retrofit techniques, number of subsidies for each technique and subsidy rates. Moreover, energy conservation performance of each retrofit technique is analysed using a computer program for calculating home primary energy consumption. The effects of the combinations of energy retrofit techniques, such as ceiling insulation, LED and latent heat recovery gas water heaters, which are selected from the view point of both energy conservation performance and subsidy performance, are shown.
