Description
Summary:This research aims to provide a design option with the lowest energy consumption in the two mentioned phases as the optimal solution. To this end, this study employs a combination of life cycle assessment (LCA), multi-objective optimization algorithm, and building information modeling (BIM) to improve sustainability in operation and demolition phases for the facade of an open office building. First, the destructive environmental effects caused by the demolition of 100 m 2 of each material were calculated by the LCA. Then after parametric modeling, geometric parameters and material data were selected from the previous step, simulation and optimization of objectives were performed, and the optimal solution was presented, which should be added to the BIM model by designing a plugin for data integration. Compared to the initial design options, selecting the appropriate parameters and materials and thus producing the optimal solution led to a 53.48 and 66.23% reduction in operational and demolition energy consumption, respectively. Applying this approach encourages architects to use innovative methods to take practical steps to improve the sustainability of their projects by choosing suitable design options.
