AN INTEGRATED ANALYSIS WITH LIFE CYCLE ASSESSMENT, BUILDING INFORMATION MODELING, AND ENVIRONMENTAL PERFORMANCE FOR WINDOW MATERIALS: ASSIUT UNIVERSITY HOSPITAL CLINIC AS A CASE STUDY

JES. Journal of Engineering Sciences ; doi:10.21608/jesaun.2020.42055.1009

Abstract: The main goal of this study is to undertake the three methods of life cycle assessment (LCA), the environmental performance (EP), and the building information modeling (BIM) to determine the environmental performance and impacts of two window frame materials: aluminum and wood. This study has been carried out in a proposed project at the Assiut University campus. The LCA has been conducted by assessing materials and processes involved in manufacturing the two window frame types using the SimaPro. The LCA scope of this research covers from cradle to the gate with a designated system boundary. The network flow has been drawn to produce one kilogram of aluminum and wood; the quantities data were gathered from the BIM (using Autodesk Revit). Selecting the database is carefully picked from the Ecoinvent dataset to be closer to Egypt's manufacturing processes. Afterwards, the IMPACT 2002+ with midpoint and endpoint calculations has been used. Finally, the LCA results have been compared with the EP results (using DesignBuilder) to determine the best choice between the two materials. The integration analysis shows that the aluminum industry has higher negative environmental impacts and environmental performance than the wood industry. The total midpoint results of the two materials are found to be 29.6 for aluminum, and 7.57 the wood. Turning to the endpoint results, human health and resource depletion impacts are the most significant results. The human health scored the highest value, with 13.9 for aluminum and 3.51 for wood. A novel framework for integrating LCA, BIM, and EP for a proposed building during the early phases of a project has been conducted in this study. The presented study can be used as a model for integrating comparative analysis on other proposed projects as the LCA applications in Egypt are scarce due to the absence of a reliable database. This study has introduced a value applying an approach to select the appropriate life cycle inventory database from the Ecoinvent dataset. The research findings contribute to choosing the most suitable window frame materials with the most energy-efficient effect and the least environmental burden. Moreover, it can help the concerned legislative bodies and the decision-makers.
