许多研究都以实证的方式研究了能源效率的提高在多大程度上会导致各种产品的反弹效应。能源效率的提高可能会导致行为变化，从而产生反弹效应。然而，有限数量的研究已经解决了电器能源效率提高可能导致什么样的行为变化。例如，空调能效的提高会导致室内温度设置的变化。本文探讨空调器能源效率的提升是否会阻碍节能行为。具体而言，我们通过日本的家庭调查，调查了与空调使用相关的节能行为：（1）在夏季将室温设定在28 °C以上;（2）减少不必要的电力消耗;（3）清洁过滤器。我们发现，能源效率的提高可以将夏季将空调温度设置在28 °C或更高的可能性降低约25-45%，而它们对减少不必要的空调使用或过滤器清洁没有影响。这一发现意味着能源效率的提高可能会抵消温度设置的节能行为，导致反弹效应。因此，我们澄清了在空调的情况下的反弹效果的机制。
Many studies have empirically examined to what extent energy efficiency improvement causes rebound effects for various products. Energy efficiency improvement potentially induces behavioral changes resulting in a rebound effect. However, a limited number of studies have addressed what kind of behavioral changes the energy efficiency improvement of appliances can cause. For example, the energy efficiency improvement of air conditioners can induce a change in the room temperature setting. This paper examines whether the energy efficiency improvement of air conditioners impedes energy-saving behaviors. Specifically, using a Japanese household survey, we examined the energy-saving behaviors related to air conditioner usage: (1) setting the room temperature at 28 °C or higher in summer, (2) reducing unnecessary power consumption, and (3) cleaning the filters. We found that energy efficiency improvements reduce the probability of the behavior of setting air conditioner temperatures at 28 °C or more by approximately 25–45% during summer, while they have no impacts on the reduction of unnecessary air conditioner usage or filter cleaning. This finding implies that energy efficiency improvements may counteract the energy-saving behaviors of the temperature setting, resulting in a rebound effect. Thus, we clarified a mechanism of the rebound effect in the case of air conditioners.
