摘要

The construction industry’s impact on the environment and economy is profound and the integration of Life Cycle Assessment (LCA) and Building Information Modeling (BIM) is crucial for sustainable development, but complex during initial design. Developing tools for seamless LCA and BIM integration automates this process and minimizes the complexity. This research addresses a critical gap in sustainable development of buildings by presenting a novel approach for the seamless integration of LCA and BIM to evaluate the life cycle environmental effects and cost analysis of building elements. The aim is to compare and assess these effects for typical and high-performance building envelopes in Iran, and provide significant insights and practical tools for enhancing the sustainability of construction industry and the society. To this end, the envelopes of a plant laboratory building in Tehran were examined, and eight other combinations were introduced in addition to the existing design. Considering a 30-year lifespan, the refined choice emerges as a roof incorporating polyisocyanurate insulation coupled with expanded polystyrene insulation for the walls. This combination delivers substantial benefits, boasting a remarkable 34.7% reduction in Life Cycle Energy (LCE) and a 6.5% reduction in Life Cycle Cost (LCC) compared to alternatives.
