Application of Digital Twin Technology in Intelligent Building Energy Efficiency Management System

Building energy utilization has always been the focus of attention from all walks of life. Taking the intelligent building energy efficiency management system as the research object, this paper discusses the application of digital twin technology in the system. This paper expounds the application scope and main functions of digital twin technology, and describes the application process. This paper identifies the types of energy consumption quotas for smart buildings and selects the sample size. The requirements of the energy efficiency management system are extracted through configuration strategies and plans, and energy consumption standards under the same load have been established. We have used the dual technology of digitally optimized equipment energy-saving modes. The case analysis results show that the energy-saving contribution rate after the transformation reaches 21.524%, exceeding the expected target of 1.524 %, which proves that the energy consumption is lower after the application of digital twin technology.
