Sustainability reports constitute a good source to check how companies have understood sustainability. The purpose of this paper is to interpret how building sustainability has been understood, defined and measured, using sustainability reports from the building value chain in Sweden. Sweden has been chosen since it is rated as a sustainability leader and could therefore be expected to be a benchmark. The analyses are based on how sustainability has been defined and what the level of reporting maturity has been. A maturity grid that assesses if the most important impacts have been considered in the entire value chain has been used. Also, it has been checked if there are indicators measuring sustainability with externally set goals. Results indicate that there seems to be no common agreement on what building sustainability is. Most studied companies have not presented a clear definition of how they have interpreted sustainable development and there is no clear focus on key issues such as climate and affordability. Sustainable building could, based on the deduced main sustainability impacts, be seen as affordable with zero carbon footprint. Fundamental Key Performance Indicators for residential building sustainability could be such as m² living per carbon footprint and per price.

可持续发展报告是检查公司如何理解可持续性的良好来源。本文的目的是使用瑞典建筑价值链中的可持续性报告来解释如何理解，定义和衡量建筑的可持续性。选择瑞典是因为它被评为可持续发展的领导者，因此有望成为基准。这些分析基于如何定义可持续性以及报告成熟度的水平。已经使用了一个成熟度网格，用于评估在整个价值链中是否考虑了最重要的影响。此外，还检查了是否有衡量可持续性的指标与外部设定的目标。结果表明，关于什么是建筑可持续性似乎尚未达成共识。大多数接受研究的公司尚未就如何解释可持续发展提出明确的定义，也没有明确关注诸如气候和负担能力等关键问题。根据推论出的主要可持续性影响，可持续性建筑可以被视为可负担的，零碳足迹。住宅建筑可持续性的基本关键绩效指标可以是每个碳足迹和每个价格^2个生活。
