A Comparison of LCA Approaches for Existing Buildings Subjected to Earthquake Considering Environmental and Structural Performance

EasyChair Preprint no. 10433

Abstract

Natural disasters such as recent earthquakes have highlighted the importance of resilience against natural hazards as a key component of sustainability. Evaluating existing buildings under sustainable perspective requires the understanding of building’s life-cycle stages exposed to these disasters. In comprehensive life-cycle-analysis (LCA) of a building, damage repair costs and downtime (economy component), environmental emissions and waste generation (environmental impact component), and deaths (society component) should be quantified and evaluated [1]. After any earthquake, damage repair costs and downtime causing harmful impacts due to additional material and energy consumption, and also generating additional waste production, despite consideration of other important impacts such as Deaths and injuries. Therefore, to minimize these impacts, Researchers have taken different approaches, they assessed the impacts of a single building in different form and details focused on whole building or individual building systems. Researchers have attempted to incorporate seismic risks into traditional building LCA models and developed appropriate methods for comparing different design alternatives with respect to the impact of seismic damages and their recovery activities. The evaluation of five LCA studies, which took into account both the environmental and structural performance of earthquake-affected structural systems, will be the primary focus of this paper. The paper will also examine the main factors that influenced the assessment's findings and provide a summary of the most significant findings of them.
