Improving the effectiveness and interaction between building information modeling and life cycle assessment

Abstract

ABSTRACT Improving the environmental impact of the construction industry is a very significant way to achieve sustainability. The combination of building information modeling and life cycle assessment leads to improve the environmental performance of buildings. However, preliminary measures to achieve sustainability require complete knowledge and classification of building information modeling uses and environmental indicators. For this purpose, it is necessary to identify and prioritize building information modeling capabilities and environmental indicators in the early stages of design. A questionnaire was designed to survey experts in this field. By evaluating the building information modeling criteria and life cycle evaluation, using the Structural equation modeling method, it was found that 3D coordination, Phase planning, and Design reviews are the most important in the success of the project. In terms of life cycle assessment, control, and reduction indicators of Global Warming Potential, Land use impact, and Total Primary Energy, it has the greatest impact on improving the sustainable performance of a construction project. We also examined the interaction between the most effective building information modeling criteria and life cycle evaluation using the Delphi method. This approach improved project sustainability performance by reducing time, cost, resource consumption, and environmental impacts.
