Digital Twin Smart Park Energy Management System

Foreword

Since the beginning of this year, the total energy consumption has continued to rise, and the demand for resources has continued to increase. The National Development and Reform Commission has issued the "Plan for Improving the Dual Control System of Energy Consumption Intensity and Total Volume." Building energy consumption, especially the energy consumption of large public buildings, accounts for a large proportion of the total energy consumption of the city. Therefore, how to effectively monitor and analyze the energy consumption of buildings, and conduct intelligent and energy-saving management of large buildings to reduce the energy required for daily operation Consumption has become the main concern of major companies.

Hightopo applies the self-developed HT visualization products to build a lightweight building fully integrated energy visualization management system. It uses 2D, 3D and other visualization methods to track and effectively manage the energy consumption of buildings in a timely manner to improve the management level of energy saving work to achieve The multiple energy coupling purposes of energy saving and interaction between supply and demand realize centralized monitoring, management and decentralized control of energy, including power distribution and lighting, air conditioning, heating, water supply and drainage of buildings, etc.
