Green building system integration into project delivery utilising BIM

摘要

The buildings contribute towards global warming; they account for the majority of global energy use and carbon dioxide emissions. In this regard, green buildings are considered as solutions to slow global warming. Many challenges exist in delivering green building solutions, determining appropriate building information modelling (BIM) execution strategies, and standardising information exchange. This study aims to improve green assessments in buildings using digital technology. It investigates the challenges in environmental assessment method's (EAM) workflow by integrating the EAM requirements in the design and construction project stages using the BIM platform. By applying a mixed-method approach, this study maps exciting EAM environmental credits against the BIM platform and Royal Institute of British Architects digital plan of works for construction projects. This is achieved through the analysis of qualitative data collected during interviews with architects, BIM experts, and environmental assessors in the UK. The results are used to propose a decision support framework using a BIM tool kit to ensure efficient project and data handling and delivery. This research addresses the elements of successful integration by investigating the factors affecting the use of performance analysis and integrating sustainability aspects within the digital plan of work. The results indicate that sustainability will take a more important role in the digitalisation of the construction sector if integrated within BIM frameworks. Furthermore, an effective decision making framework aids in addressing the sustainability targets and mitigating the negative impacts of the construction sector.
