This book focuses on the implementation of Quality FunctionDeployment (QFD) in the construction
industry as a tool to help buildingdesigners arrive at optimal decisions for external envelope
systems withsustainable and buildable design goals. In particular the book integratesspecial
features into the conventional QFD tool to enhance its performance.These features include a
fuzzy multi-criteria decision-making method fuzzyconsensus scheme and Knowledge Management
System (KMS). This integrationresults in a more robust decision support tool known as the
Knowledge-basedDecision Support System QFD (KBDSS-QFD) tool. As an example the KBDSS-QFD
toolis used for the assessment of building envelope materials and designs for
high-riseresidential buildings in Singapore in the early design stage. The book providesthe
reader with a conceptual framework for understanding the development of theKBDSS-QFD tool. The
framework is presented in a generalized form in order tobenefit building professionals
decision makers analysts academics andresearchers who can use the findings as guiding
principles to achieve optimalsolutions and boost efficiency.
