Abstract
The construction materials used in a building have an impact on its sustainability. The embodied energy of a building, energy used in the materials manufacturing process, carbon dioxide emissions to the environment and overall environmental and economic implications can all be reduced with optimal material selection.
In this study, the Green Pyramids Rating System GPRS (second edition) was used to reduce the negative environmental impact of using construction materials. Thus, this research introduces a method for determining if a material meets the materials and resources criterion. The proposed method could be utilized to assess the environmental dimension of sustainability in the building materials used in various housing projects. It also aids in the selection of sustainable building materials, either alone or in combination with other objectives, such as life cycle cost in this study.
Based on a multi-criteria decision model, this study intends to establish a decision-making framework to assist practitioners in selecting local eco-friendly building materials for Egyptian housing projects. The study accomplishes this by combining two distinctive objectives: (i) the material’s life cycle cost, and (ii) credits earned by the material through the modified method for assessing the building materials in GPRS proposed. The optimum solutions are determined using the VIKOR technique. A desktop application is created to facilitate the developed framework for selecting the optimum sustainable building materials. The application is characterized by its flexibility in editing or adding sustainable building materials properties and friendly-using.
