A Multi-Criteria Decision Support System for the Selection of Low-Cost Green Building Materials and Components

The necessity of having an effective computer-aided decision support system in the housing construction industry is rapidly growing alongside the demand for green buildings and green building products. Identifying and defining financially viable low-cost green building materials and components, just like selecting them, is a crucial exercise in subjectivity. With so many variables to consider, the task of evaluating such products can be complex and discouraging. Moreover, the existing mode for selecting and managing, often very large information associated with their impacts constrains decision-makers to perform a trade-off analysis that does not necessarily guarantee the most environmentally preferable material. This paper introduces the development of a multi-criteria decision support system (DSS) aimed at improving the understanding of the principles of best practices associated with the impacts of low-cost green building materials and components. The DSS presented in this paper is to provide designers with useful and explicit information that will aid informed decision-making in their choice of materials for low-cost green residential housing projects. The prototype MSDSS is developed using macro-in-excel, which is a fairly recent database management technique used for integrating data from multiple, often very large databases and other information sources. This model consists of a database to store different types of low-cost green materials with their corresponding attributes and performance characteristics. The DSS design is illustrated with particular emphasis on the development of the material selection data schema, and application of the Analytical Hierarchy Process (AHP) concept to a material selection problem. Details of the MSDSS model are also discussed including workflow of the data evaluation process. The prototype model has been developed with inputs elicited from domain experts and extensive literature review, and refined with feedback obtained from selected expert builder and developer companies. This paper further demonstrates the application of the prototype MSDSS for selecting the most appropriate low-cost green building material from among a list of several available options, and finally concludes the study with the associated potential benefits of the model to research and practice.

竹纤维增强金尾矿砂加气混凝土性能研究

以竹纤维为增强材料制备B06级金尾矿砂加气混凝土,分析了竹纤维掺量和长度对竹纤维砂加气混凝土(BFAAC)料浆流动性、发气高度、干密度和抗压强度等的影响;采用XRD及SEM分析了BFAAC的物相组成和微观结构。结果表明:随着竹纤维掺量的增加,BFAAC的料浆流动性、发气高度逐渐下降,试样干密度逐渐增大,抗压和抗折强度先提高后降低,竹纤维的最佳掺量为0.3%。竹纤维长度对BFAAC浆料性能和制品基本物理力学性能影响不明显。XRD和SEM分析表明,BFAAC的水化产物主要是托贝莫来石和少量C-S-H;竹纤维不参与基体材料之间的水化反应,而是通过物理作用达到增强效果。
