The South Korean government has been providing information on home energy efficiency since 2001 in order to incentivize improvements in the energy efficiency of both existing and new buildings. Whether such information provision delivers the intended outcomes hinges on consumers’ preferences for home energy efficiency in the real estate market. This study investigates South Korean consumers’ preferences for home energy efficiency in the real estate market by applying a choice experiment approach. Using a conditional logit model and a latent class model, this study concludes that less than 20% of Korean consumers consider home energy efficiency as a significant factor in their housing decisions and identifies the sources of taste variations in Korean consumers’ preferences for home energy efficiency. The findings of this study imply that the current information programs on home energy efficiency in South Korea should be much improved to achieve its goal.

自2001年以来，韩国政府一直在提供有关家庭能源效率的信息，以鼓励改善现有建筑物和新建筑物的能源效率。此类信息的提供是否能够达到预期的结果，取决于消费者对房地产市场中家庭能源效率的偏好。这项研究通过应用选择实验方法，调查了韩国消费者对房地产市场中家庭能源效率的偏好。使用条件对数模型和隐性类模型，该研究得出的结论是，不到20％的韩国消费者将家庭能源效率视为其住房决策的重要因素，并确定了韩国消费者对家庭能源效率的偏好中口味差异的根源。
