The focus of this paper is to extract clear and objective information to assist specifiers in the building sector in selecting materials with a lower basic environmental impact, specifically insulation materials that form the insulating layer within the thermal envelope. For this purpose, a selection of representative materials has been made, for which information related to their Life Cycle Assessment (LCA) in stages A1 to A3 (product stage), C1 to C4 (end of life stage), and D (benefits and impacts beyond the system boundary) is available through their Environmental Product Declaration (EPD) documents. To obtain the expected results, data processing and analysis related to each of the impact categories defined in EN15804 + A2 have been conducted. To carry out a complete life cycle analysis that includes other phases, it is necessary to conduct a study of the specific case, considering its unique circumstances and characteristics, including location and factors that affect different stages, such as transport and assembly. However, the stages considered in this study provide the most relevant information for decision-making, as well as estimated information if the source data for these stages are not available.

建筑保温材料的比较评估：整个生产、报废和超出系统边界的环境绩效


本文的重点是提取清晰客观的信息，以帮助建筑领域的规范制定者选择对基本环境影响较小的材料，特别是形成热围护结构内绝缘层的绝缘材料。为此，我们精选了一些具有代表性的材料，其中与其在 A1 至 A3 阶段（产品阶段）、C1 至 C4阶段（生命周期结束阶段）和 D阶段（超出系统边界的利益和影响）的生命周期评估 （LCA） 相关的信息可通过其环境产品声明 （EPD） 文件获得。为了获得预期的结果，已经进行了与 EN15804 + A2 中定义的每个影响类别相关的数据处理和分析。为了进行包括其他阶段的完整生命周期分析，有必要对具体案例进行研究，考虑其独特的情况和特征，包括位置和影响不同阶段的因素，例如运输和组装。但是，本研究中考虑的阶段为决策提供了最相关的信息，如果这些阶段的源数据不可用，则还会提供估计信息。
