This paper reviews actual sustainability assessments in the construction sector to define whether and how a Life Cycle Sustainability Assessment (LCSA) is applied and interpreted in this sector today. This industry has large shares in global energy (33%), raw material consumption (40%) and solid waste generation (40%). Simultaneously, it drives the economy and provides jobs. The LCSA is a method to identify environmental, social and economic impacts of products/services along their life cycles. The results of this study showed a mismatch between sectoral emissions and the number of LCSA-based impact evaluations. It was found that only 11% of papers reviewed assessed all three sustainability pillars. The economic and especially the social pillars were partly neglected. In Life Cycle Assessments (LCAs), 100% made use of Global Warming Potential (GWP) but only 30% assessed more than five indicators in total. In Life Cycle Costing (LCC), there were a variety of costs assessed. Depreciation and lifetime were mainly neglected. We found that 42% made use of Net Present Value (NPV), while over 50% assessed individual indicators. For the Social Life Cycle Assessment (S-LCA), the focus was on the production stage; even the system boundaries were defined as cradle-to-use and -grave. Future approaches are relevant but there is no need to innovate: a proposal for a LCSA approach is made.

生命周期可持续性评估在建筑行业的应用：系统文献综述

本文回顾了建筑行业的实际可持续性评估，以确定当今是否以及如何在该行业应用和解释生命周期可持续性评估 (LCSA)。该行业在全球能源（33%）、原材料消耗（40%）和固体废物产生（40%）中占有很大份额。同时，它推动经济并提供就业机会。LCSA 是一种识别产品/服务在其生命周期中对环境、社会和经济影响的方法。这项研究的结果表明，部门排放与基于 LCSA 的影响评估数量之间存在不匹配。结果发现，只有 11% 的论文评估了所有三个可持续性支柱。经济支柱，尤其是社会支柱部分被忽视了。在生命周期评估 (LCA) 中，100% 使用了全球变暖潜能值 (GWP)，但只有 30% 评估了总共超过五个指标。在生命周期成本法 (LCC) 中，评估了多种成本。折旧和寿命主要被忽略。我们发现 42% 的人使用了净现值 (NPV)，而超过 50% 的人评估了单个指标。对于社会生命周期评估 (S-LCA)，重点是生产阶段；甚至系统边界也被定义为“从摇篮到使用”和“坟墓”。未来的方法是相关的，但没有必要创新：提出了 LCSA 方法的建议。而超过 50% 的人评估了个别指标。对于社会生命周期评估 (S-LCA)，重点是生产阶段；甚至系统边界也被定义为“从摇篮到使用”和“坟墓”。未来的方法是相关的，但没有必要创新：提出了 LCSA 方法的建议。而超过 50% 的人评估了个别指标。对于社会生命周期评估 (S-LCA)，重点是生产阶段；甚至系统边界也被定义为“从摇篮到使用”和“坟墓”。未来的方法是相关的，但没有必要创新：提出了 LCSA 方法的建议。
