The huge amount of energy consumed by the residential buildings makes the sector one of the principal sources affecting the energy use in the European countries. To face it, the renovation of the building stock is considered one of the key strategies to improve the energy performance of buildings and meet the energy efficiency targets. Thus, a full understanding of the building stock and renovation market is crucial to meet the objectives of energy efficiency strategies. This research presents the findings of an extensive research on the residential building stock and retrofit market in France, Italy, Spain, Slovenia and Austria and a detailed comparative analysis is developed to assess the quality and the level of the data sources. The weighting method is adopted in this paper as an analytic approach in order to evaluate the main indicators of the data collected and to highlight the commonalities and the differences of building data among European countries. The results of this analysis are considered as valuable vademecum aims to support the experts and the different stakeholders in the data collection process and initiates the opportunities for standardizing data collected from European countries. This research is a part of a European project H2020 (heartproject.eu).

住宅建筑消耗的大量能源使该行业成为影响欧洲国家能源使用的主要来源之一。面对这一问题，建筑材料的翻新被认为是改善建筑物能源性能和达到能效目标的关键策略之一。因此，全面了解建筑存量和装修市场对于实现节能战略的目标至关重要。这项研究提出了对法国，意大利，西班牙，斯洛文尼亚和奥地利的住宅建筑存量和改造市场进行的广泛研究的结果，并进行了详细的比较分析以评估数据源的质量和水平。本文采用加权法作为一种分析方法，以评估所收集数据的主要指标，并强调欧洲国家之间建筑数据的共性和差异。该分析结果被认为是宝贵的建议，旨在在数据收集过程中为专家和不同利益相关者提供支持，并为标准化从欧洲国家收集的数据提供了机会。该研究是欧洲项目H2020（heartproject.eu）的一部分。该分析结果被认为是宝贵的建议，旨在在数据收集过程中为专家和不同利益相关者提供支持，并为标准化从欧洲国家收集的数据提供了机会。该研究是欧洲项目H2020（heartproject.eu）的一部分。该分析结果被认为是宝贵的建议，旨在在数据收集过程中为专家和不同利益相关者提供支持，并为标准化从欧洲国家收集的数据提供了机会。该研究是欧洲项目H2020（heartproject.eu）的一部分。
