| Abstract |
Functional, structural, design, economic and defect factors must be comprehensively considered in tandem with objective evaluation criteria
when deciding upon exterior building materials. If end-users or engineers are not knowledgeable about durability and defect factors of exterior
building materials, then there is a high probability of making an inappropriate selection; they should clarify the various requirements for
cladding and then implement the proper performance evaluation. In this study, a QFD-TOPSIS model is proposed for end-users and
professionals to collectively participate and apply during the decision-making process of selecting exterior building materials. The multi-criteria
decision-making model used by project participants enabled the most appropriate choice in actual examples of exterior material selection
provided in this study. The case study comparing the QFD-TOPSIS method from multiple experts, end-users, and manufacturers and the VE
method by one expert confirmed that the QFD-TOPSIS method required more empirical evidence and detailed evaluation of select exterior
building materials. |
