ABSTRACT:
Current environmental problems arising from the building sector require tools to help reduce resource consumption and environmental impact. Life Cycle Assessment (LCA) is a widely used tool to quantify the environmental impacts of the building sector. The literature recognizes the need to simplify the method application, especially to reduce and optimize data acquisition. Building Information Modeling (BIM) is defined as a virtual 3D building model which integrates with a database of their building elements. Several studies recognize that the integration of BIM and LCA can simplify data acquisition of the building as well as provide both tools with feedback. This paper reviews recent studies centered on BIM-based LCA, and also carries out a methodological analysis of their integration, focusing on the way that BIM can contribute to simplifying data input, and optimize output data and results during the LCA application in buildings. The results show the viability to develop methods based on BIM models for organizing building information used to estimate environmental and energy consumption impacts based on LCA, including: templates and plug-ins for BIM software, and the integration of automated processes combining different data and software. Reviewed papers are simplified LCA applications, mostly focused on CO2 emission calculation during the early stages of design. Finally, methodological challenges and recommendations for BIM and LCA tools are propose.
HIGHLIGHTS:
Review of recent studies centered on BIM-based LCA.
Focus on the way that BIM can contribute to simplify input and optimize output.
Most of reviewed papers are focused on CO2 emission calculation.
Study evidences the need to establish guidelines to assist in BIM-LCA integration.
