Towards Circular Built Environment: Assessing Building Circularity Embodied Carbon Using BIM
並列摘要
Moving towards a circular built environment is one way to solve problems on consumptions of natural resources, waste generation, and climate change happening worldwide. In the current practice, manufacturing of building components and constructing buildings are polluting the environment. During the construction stage, raw materials from nature are processed to building materials and assembled onsite. These processes also emit huge amount of greenhouse gases which are directly linked to global warming. Furthermore, buildings generate tons of solid waste when they are demolished at the end of their life. To alleviate these problems, construction projects have started to adopt circular economy concepts into their designs. This research aims to propose an approach to utilize building information modelling (BIM) in implementation of circular concept design through the assessment of building circularity and embodied carbon. A BIM tool is developed with Dynamo to assess the building circularity and embodied carbon directly from a BIM model inside Revit. By extracting information from a BIM model and linking those to a material database, building circularity and embodied carbon can be computed. This will enable simulations of different design scenarios to be carried out. In addition, material databank is also generated to store information of available building materials for future planning. The implementation of the tool is presented in a case study, and some circular material alternatives are proposed as design alternatives. From the obtained results, the tool is successful in assessing the building circularity and embodied carbon of the project, including indicating the circular material alternatives have improved the final results. This research could help designers in decision making of building design and material selection for achieving a circular built environment.
