This paper proposes a methodology for the assessment of the sustainability among three different structural design alternatives for a single-family home. The response associated with each alternative has been measured using 43 indicators considering all stages of the life cycle. A decision-making model is carried out on the basis of a neutrosophic group analytical hierarchy process (NAHP-G) capturing the maximum information in terms of credibility, inconsistency and indetermination. The 9 criteria on which an expert group intervenes are finally evaluated using VIKOR. The results show that non-probabilistic uncertainties influence the weights obtained, with maximum deviations in the criteria between 11.91% and 4.95%, if compared to conventional AHP. From the methodology it is obtained that the technological alternative with non-conventional concrete performs best in sustainable terms. Although the industrialized option has less environmental impact, only the simultaneous consideration of the economic, environmental and social pillars in a project will lead to appropriate sustainable designs.

本文提出了一种评估单户住宅的三种不同结构设计备选方案中的可持续性的方法。考虑到生命周期的所有阶段，已使用43个指标测量了与每个替代方案相关的响应。决策模型是在中智群分析层次过程（NAHP-G）的基础上进行的，该过程从可信性，前后不一致和不确定性方面获取了最大的信息。最终，使用VIKOR对专家组进行干预的9条标准进行了评估。结果表明，与常规AHP相比，非概率不确定性会影响获得的权重，标准中的最大偏差在11.91％和4.95％之间。从方法学上可以看出，采用非常规混凝土的技术替代方案在可持续性方面表现最佳。尽管工业化方案对环境的影响较小，但只有同时考虑项目中的经济，环境和社会支柱，才能进行适当的可持续设计。
