To expedite the decarbonization of residential buildings, it is essential to focus on deep renovations due to their superior primary energy savings. However, detailed profiling of renovators and their activities remains underexplored. Therefore, this paper aims to expand our understanding of Belgian renovators by cross-referencing sociodemographic factors with renovation activities through a large-scale quantitative analysis. Utilizing two-sample proportion tests, the study demonstrates that, besides homeowner age, factors such as region, education level, type of ownership, and construction period result in distinct segments of renovators. The youngest generation (25–39 years), despite constituting the smallest demographic of homeowners, is identified as the most active renovator and is more inclined to undertake deep renovations. Nevertheless, potential lock-in effects remain. The oldest generation (55–74 years) requires additional motivation to engage in energy renovations and to undertake multiple renovation works. The distinct segments of renovators identified in this study provide a clearer understanding of where bottlenecks and opportunities exist for promoting deep renovation. These insights allow Belgian governments and businesses to develop tailored communication and incentive programs, effectively addressing the specific needs of various renovator groups and facilitating a more rapid uptake of retrofitting by homeowners.

深度（能源）改造的潜力在哪里？2018 年至 2022 年比利时家庭装修活动的大规模研究


为了加快住宅建筑的脱碳，必须专注于深度改造，因为它们可以节省一次能源。然而，对装修商及其活动的详细分析仍未得到充分探索。因此，本文旨在通过大规模定量分析将社会人口因素与装修活动进行交叉引用，从而扩大我们对比利时装修商的理解。利用双样本比例检验，该研究表明，除了房主年龄外，地区、教育水平、所有权类型和施工期等因素也会导致装修者的不同细分。最年轻的一代（25-39 岁）尽管构成了最小的房主群体，但被认为是最活跃的装修者，并且更倾向于进行深度装修。尽管如此，潜在的锁定效应仍然存在。最老的一代（55-74 岁）需要额外的动力来从事能源改造和进行多项改造工作。本研究中确定的翻新商的不同细分市场让我们更清楚地了解促进深度翻新的瓶颈和机会所在。这些见解使比利时政府和企业能够制定量身定制的沟通和激励计划，有效满足各种装修群体的特定需求，并促进房主更快地接受改造。
