The Life-Cycle Assessment (LCA) is a standard approach for evaluating the environmental impacts of products and processes. This paper presents the LCA of Living Wall Systems (LWS), a new technology for greening the building envelope and improve sustainability. Impacts of manufacture, operation, and use of the systems selected, were evaluated through an LCA. LWS are closely related to several environmental benefits, including improved air quality, increased biodiversity, mitigation of heat island effects, and reduced energy consumption due to savings in indoor cooling and heating. Two prototypes have been selected, taking into account the modularity and the use of organic substrate as selection criteria. The systems evaluated were a plastic-based modular system and a felt-based modular system. The inventory data was gathered through the manufacturers. The LCA approach has been used to assess the impact of these solutions by focusing on the construction phase and its contribution to both the energy balance and the entire life cycle of a building. This approach has never been done before for LWS. The study found that out of the two systems through the manufacturing, construction, and maintenance stage of the LCA, the felt-based LWS has an impact on almost 100% of the impact categories analyzed, while plastic-based LWS has the lowest influence on the total environmental impact.
生命周期评估（LCA）是评估产品和工艺环境影响的标准方法。本文介绍了用于绿化建筑围护结构和提高可持续性的新型技术——立体绿化系统（LWS）的生命周期评估。通过生命周期评估，评估了系统制造、运行和使用的影响。LWS 与包括改善空气质量、增加生物多样性、缓解热岛效应以及通过室内冷却和加热节省能源来减少能源消耗在内的多项环境效益密切相关。考虑到模块化和有机基质的使用，选择了两个原型作为选择标准。评估的系统是基于塑料的模块化系统和基于毛毡的模块化系统。清单数据是通过制造商收集的。LCA 方法已用于通过关注建筑阶段及其对建筑的能源平衡和整个生命周期的贡献来评估这些解决方案的影响。这是以前从未对 LWS 进行过的研究。研究发现，在 LCA 的制造、施工和维护阶段，毛毡基 LWS 对分析的几乎所有影响类别都有影响，而塑料基 LWS 对总环境影响的影响最小。
