During last decade, design for deconstruction (DfD) has attracted the attention of researchers and project managers as an environmentally friendly alternative to the conventional demolition of buildings. Yet, the intensity of raw materials consumption, waste generation and greenhouse gas (GhG) emission in the construction industry proves that current methods of selecting building components have failed to make the deconstruction effectively feasible. Specifically, in the material selection process, most research studies concentrate on assessing environmental and economic aspects while in selecting material for DfD various factors must be considered. To overcome this gap, this study aims to propose a DfD-based material selection model which enables designers to choose materials that make the recyclability and reusability of building components feasible. To this end, the Kano model is first applied to categorize selection criteria identified via a questionnaire. After extracting the weights of criteria by using Fuzzy-Analytical Hierarchy Process, a Technique for Order Preference by Similarity to the Ideal Solution-based multi-criteria decision-making framework is proposed for choosing the best possible alternatives. Based on the research results, the framework enables designers to find decent materials in terms of DfD requirements. A numerical example is also provided to examine the proposed framework for selecting the most appropriate materials for walls.
在过去的十年中，面向拆卸设计（DfD）作为一种对建筑物进行环保拆除的替代方法，引起了研究人员和项目经理的关注。然而，建筑行业原材料消耗、废物产生和温室气体（GhG）排放的强度表明，目前选择建筑构件的方法未能使拆卸有效地可行。具体来说，在材料选择过程中，大多数研究集中在评估环境和经济方面，而在选择 DfD 材料时，必须考虑各种因素。为了克服这一差距，本研究旨在提出一种基于 DfD 的材料选择模型，使设计师能够选择使建筑构件可回收和可重复使用的材料。为此，首先通过问卷调查对选择标准进行了 Kano 分类。利用模糊层次分析法提取标准权重后，提出了基于理想解排序法的多准则决策框架，以选择最佳的替代方案。根据研究结果，该框架使设计师能够根据 DfD 要求找到合适的材料。还提供了一个数值示例，以检验用于选择最适合墙壁的材料的建议框架。
