本研究探讨增购及更换高能效冷气机对节省电力的影响。我们采用问卷调查的方式，对339户日本家庭的用电数据进行了测量，这些数据来自两个政府要求不同程度节电率的城市地区，即大阪（10%）和松山（5%）。本研究的主要发现如下：(1)购买节能空调的家庭比没有购买节能空调的家庭节省更多的电力。(2)“增购户”节能效果显著，“替代户”节能效果不显著。反弹效应可能会抵消新空调的节能效果。(3)利他态度与更积极的节能参与相关。(4)大阪的家庭比松山省的多，可能是因为政府的节电号召更有力。
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) “Additional-purchase households” showed significant energy savings, whereas “replacement households” 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.
