Abstract
Given the massive growth in new construction and the inefficiencies of the existing construction materials industry, the environmental impacts, the natural resources depletion, construction wastes exacerbate through the years. In addition, there is a need for Actual Performance-Based Tools instead of generic Rating Systems (RSs). All these issues are the driving forces for the building construction sector to be targeted for ecologically sustainable development. Despite the promising approach; Life Cycle Assessment (LCA) in evaluating the building materials impacts throughout their entire life, it has a number of key challenges facing architects. Consequently, this study aims to fill this gap by thoroughly tracking and quantifying all impacts of the building life cycle with instant readable results and also overcoming the complex and time-consuming issues. The BIM-LCA integration has the potential to automate the LCA procedure in the early design stage within the BIM environment by using material specifications and material quantity take-off that are already included in the BIM model. Throughout the analysis of the environmental performance of the repetitive residential building enclosure; Dar Misr project, various scenarios were proposed as materials alternatives for the uppermost contributors to the environmental impacts. As a result of changes in the two material factors; Specification and Quantity factors, the optimum proposal can be presented with the required changes and suitable enhancement. It can ensure the importance of adopting the BIM-LCA integration approach in the early design stage. The final result is introducing a number of recommendations for different stakeholders related to the Construction Material Industry with the aim of supporting the LCA practices in the Egyptian market.
