Life Cycle Assessment of an Institutional building using OpenLCA software

Abstract

Abstract There is a growing recognition in the construction industry of the need to reduce the environmental impacts of buildings and construction projects. This has led to a focus on quantifying and minimizing the energy, carbon, and material footprints of buildings and construction projects, as well as on implementing sustainable design strategies. The combination of tools like Building Information Modeling (BIM) and Life Cycle Assessment (LCA) are becoming more common as a way to better understand the environmental impacts and to identify opportunities for improvement. By taking a proactive approach to sustainability, the construction industry can play a key role in reducing the overall environmental impact of the built environment. This study is focuses on case study of analysing the environmental impacts of different components of building such as columns, beams, masonry, slabs in an institutional building and determining the impacts on the environment. Masonry with fired clay bricks was found to be the component with maximum environmental impacts and different alternative materials for replacement such as fly ash bricks were assessed in Open-LCA software using Ecoinvent database. Environmental impacts of fired clay bricks and fly ash bricks were compared. Results of reduction in environmental impact are presented.
