BIM-based operational energy management offers effective control over energy consumption. By leveraging BIM technology, it is possible to comprehensively analyze and collect data on building energy use. Energy consumption is broken down through a hierarchical model, allowing detailed analysis across various dimensions such as time. This approach facilitates comparison and evaluation of different energy subcategories. The goal is to carry out energy consumption analysis and optimize energy-saving measures during building operation, ultimately minimizing energy use during stable operation.
Integrating BIM technology with cloud computing, sensors, and controllers allows for real-time analysis and diagnosis of building energy consumption. Once the analysis is complete, detailed reports are generated to enable automatic control of energy-consuming systems such as HVAC and fire protection. This system provides building owners with real-time energy consumption monitoring, remote control capabilities, and tailored energy-saving management strategies.
Key benefits include:
(1) The integration of BIM with energy meters equipped with sensing functions provides immediate feedback on energy consumption to the management system. This visibility makes it easy to understand and analyze energy usage at a glance.
(2) BIM technology interfaces with water meters to visually map the building’s water network for owners, monitor water pressure, and assess water balance. Continuous monitoring and analysis of the water network data help quickly detect pipe damage, allowing for timely maintenance.
(3) The BIM operation and maintenance platform collects data from temperature monitoring points throughout the building, as well as humidity, CO2 concentration, light intensity, and other environmental factors. It enables adjustment of observation temperature ranges, highlights areas with extreme temperatures, and provides historical temperature trends from each monitoring point. Based on this information, adjustments to HVAC and ventilation systems can be made. Parameters such as air conditioning output temperature, airflow, and room humidity are fine-tuned using BIM technology to enhance energy savings.
