This study empirically estimated disaggregate market transaction costs facing single-family house-owners when energy renovating their dwelling. Two types of energy renovations are analysed: heat insulation and energy-saving windows. An analytical framework was developed including an adjustment mechanism for time-biases displayed by households. The decision process was modelling in three steps where households can be either latent, potential or actual clients to an energy renovation project. Data was collected by web-based surveys. The transaction costs are estimated based on time assessment, income levels and monetary expenditures occurring in the decision process. The results suggest that the magnitude of the transaction costs can be an important barrier to energy renovations. For energy-saving windows, transaction costs can constitute more than 50% of the investment cost, and almost 24% for heat insulation. The largest potential reduction in the transaction costs is found in the implementation phase.

本研究根据经验估计了单户住宅业主在对其住宅进行能源翻新时所面临的分解市场交易成本。分析了两类能源改造：隔热和节能窗。制定了一个分析框架，包括针对家庭表现出的时间偏差的调整机制。决策过程分三个步骤进行建模，其中家庭可以是能源改造项目的潜在客户、潜在客户或实际客户。数据是通过基于网络的调查收集的。交易成本是根据决策过程中发生的时间评估、收入水平和货币支出来估计的。结果表明，交易成本的高低可能是能源改造的重要障碍。对于节能窗，交易成本可占投资成本的 50% 以上，绝热约占 24%。交易成本的最大潜在降低出现在实施阶段。
