Abstract: This study examined the influence of additional and replacement purchases of energy-efficient air-conditioners on power savings. We used a questionnaire survey and measured electricity use data from 339 Japanese households, collected from two city areas with different level of government-requested electricity-saving rates, namely, Osaka (10%) and Matsuyama (5%). The main findings of our study are as follows: 1) Households that purchased energy-efficient air-conditioners saved more electricity than those that did not. 2) gAdditional-purchase households h showed significant energy savings, whereas greplacement households h did not. The rebound effect may negate the energy-saving effects of a new air-conditioner. 3) Altruistic attitude is associated with more active participation in power saving. 4) Households in Osaka saved more electricity than those in Matsuyama, probably because the government call to save electricity was more forceful.
