Digital Twin-based Framework for Green Building Maintenance System

This study analyses the characteristics and theoretical basis of green building maintenance system (GBMS) and proposes a digital twin(DT)-based framework for GBMS (DT-GBMS). This framework helps operation teams solve the problem of insufficient informatization and automatic management ability of green building maintenance. Besides, the structure of DT-GBMS is designed in detail according to practical usage. Finally, a prototype based on Bentley Systems software is developed by using 3D laser scanner and sensors to verify the feasibility of the proposed framework. The results indicate that the DT-GBMS can reflect the accurate and real-time status of green buildings and is able to improve the efficiency of green building maintenance by automatic management.
