本文的目的是确定通过解构设计（DfD）有效回收材料所需的关键成功因素（CSF）。本文采用的研究方法是基于顺序探索性混合方法策略。在全面查阅文献和进行四次焦点小组讨论（fgd）后，我们确定了43个DfD因素，并将其纳入问卷调查。数据分析包括Cronbach’s alpha信度分析、显著性指数均值检验和探索性因子分析。因子分析的结果揭示了五个DfD因子组的潜在因子结构，包括“严格的立法和政策”、“解构设计过程和能力”、“材料回收设计”、“材料再利用设计”和“建筑灵活性设计”。这些DfD因素组表明，对DfD的要求超越了技术能力，严格的立法和政策、设计过程和解构能力等非技术因素是设计可解构建筑的关键。注意在所有这些类别中确定的因素将有助于解决可能阻碍动态发展方案有效性的障碍。这项研究的结果将有助设计及项目经理了解，采用物料流动法作为转移堆填区废物的策略，可在哪些方面有所改善。
The aim of this paper is to identify Critical Success Factors (CSF) needed for effective material recovery through Design for Deconstruction (DfD). The research approach employed in this paper is based on a sequential exploratory mixed method strategy. After a thorough review of literature and conducting four Focus Group Discussion (FGDs), 43 DfD factors were identified and put together in a questionnaire survey. Data analyses include Cronbach’s alpha reliability analysis, mean testing using significance index, and exploratory factor analysis. The result of the factor analysis reveals that an underlying factor structure of five DfD factors groups that include ‘stringent legislation and policy’, ‘deconstruction design process and competencies’, ‘design for material recovery’, ‘design for material reuse’, and ‘design for building flexibility’. These groups of DfD factor groups show that the requirements for DfD goes beyond technical competencies and that non-technical factors such as stringent legislation and policy and design process and competency for deconstruction are key in designing deconstructable buildings. Paying attention to the factors identified in all of these categories will help to tackle impediments that could hinder the effectiveness of DfD. The results of this study would help design and project managers to understand areas of possible improvement in employing DfD as a strategy for diverting waste from landfills.
