ABSTRACT
The European Union Green Deal is a roadmap to transform the EU economy by turning the issues into opportunities. The built environment is an important sector that can expedite the process of achieving the Sustainable Development Goals (SDGs) and has the potential to impact other industries as well. The adoption of the green building rating system globally has proved to be a paradigm shift in the construction industry. The demand for green buildings is increasing and the industries are also adapting to meet the demands of the green buildings. The research develops a Green Digital Twin (GDT) framework to be executed with the aims to take advantage of the Building Information Modeling (BIM) data, Internet of things (IoT), and virtual reality (VR) to replace the static checklist of sustainability with dynamic indicators and proposes performance verification by using VR. The data coming from the BIM has been analyzed in VR to check the compliance of LEED credits from the material and resources category. The furniture EPDs and recycled content of the building elements were verified in the VR. A comprehensive framework for sustainability assessment in which there are several digital twin models for each KPI is presented and results validated. The applications of this research are multilayered as it provides an effective methodology to digitalize the process of credits verification, data visualization, and real-time monitoring of the parameters through the GDT. The use of VR in conjunction with digital twin (DT) can accelerate the green building certification process and fast credit compliance check of green building rating systems.
