Abstract Use of phase change materials (PCMs) in building envelopes has potential to improve the energy performance of buildings. Even though Multi-Criteria Decision-Making (MCDM) tools have been widely applied to rank PCMs for various applications, the following issues still need more elaboration: a) How to account for the climate-related factors in the ranking of PCMs? b) How can the environmental footprint and chemical properties of various PCMs be considered in the ranking of PCMs? Therefore, this study presents a methodology for ranking phase change materials based on the AHP–TOPSIS and Fuzzy AHP–Modified Fuzzy TOPSIS methods combined with building energy simulations. Thermophysical (thermal conductivity, latent heat of fusion, phase change temperature, specific heat, density, cycling stability, supercooling), economic (initial cost), chemical (toxicity, flammability, corrosiveness), and environmental (recyclability, embodied energy) criteria were considered. The application of the methodology was demonstrated for eight cities of the tropical savanna climate zone. A comparative analysis was conducted, and the rankings obtained utilizing AHP–TOPSIS and Fuzzy AHP–Modified Fuzzy TOPSIS methods were found to be concordant. A sensitivity analysis indicated that the ranking developed by the proposed methodology has considerable robustness to alteration of weightings of criteria.

使用多标准决策工具结合能源模拟对建筑立面应用的 PCM 进行排名

摘要 在建筑围护结构中使用相变材料 (PCM) 具有提高建筑能源性能的潜力。尽管多标准决策 (MCDM) 工具已广泛应用于对各种应用的 PCM 进行排名，但以下问题仍需要更多阐述： a) 如何在 PCM 排名中考虑气候相关因素？b) 如何在 PCM 的排名中考虑各种 PCM 的环境足迹和化学特性？因此，本研究提出了一种基于 AHP-TOPSIS 和模糊 AHP-Modified Fuzzy TOPSIS 方法结合建筑能源模拟的相变材料排序方法。热物理（热导率、熔化潜热、相变温度、比热、密度、循环稳定性、过冷）、经济（初始成本）、考虑了化学（毒性、易燃性、腐蚀性）和环境（可回收性、隐含能源）标准。该方法的应用在热带稀树草原气候区的八个城市进行了演示。进行了比较分析，发现使用 AHP-TOPSIS 和 Fuzzy AHP-Modified Fuzzy TOPSIS 方法获得的排名是一致的。敏感性分析表明，由提议的方法开发的排名对标准权重的改变具有相当大的稳健性。并且发现使用 AHP-TOPSIS 和 Fuzzy AHP-Modified Fuzzy TOPSIS 方法获得的排名是一致的。敏感性分析表明，由提议的方法开发的排名对标准权重的改变具有相当大的稳健性。并且发现使用 AHP-TOPSIS 和 Fuzzy AHP-Modified Fuzzy TOPSIS 方法获得的排名是一致的。敏感性分析表明，由提议的方法开发的排名对标准权重的改变具有相当大的稳健性。
