The Relationship between BMS and EMS

Although the building management system (BMS) and the energy management system (EMS) seem different, they are actually closely related. BMS is responsible for the automation control of the entire building, including HVAC (heating, ventilation and air conditioning), lighting, security, elevators, etc. EMS focuses on the energy consumption of the building, and achieves energy conservation and emission reduction through monitoring, analysis and optimization.

The relationship between BMS and EMS can be summarized as follows:

• EMS is a subsystem of BMS: EMS is usually nested in BMS, and uses the data collected by BMS for deeper energy analysis and optimization.
• BMS provides data foundation for EMS: The data collected by BMS on the operating status of building equipment, energy consumption, etc. provides raw data for EMS analysis.
• EMS provides optimization suggestions for BMS: EMS provides optimization suggestions for BMS by analyzing data, helping BMS to better control building equipment and achieve energy conservation.

The role of gateways in EMS and BMS

EMS involve a variety of devices, including sensors, controllers, actuators, etc. These devices may use different communication protocols (Modbus, IEC101, IEC104, DLT/645, etc.). BMS also involve a large number of devices, including lighting systems, air conditioning systems, access control systems, etc. The role of gateways in BMS is similar to that in EMS:

• Protocol conversion: convert the protocols of different devices into a unified protocol to achieve interconnection.
• Data integration: integrate massive data from different subsystems onto a unified platform for centralized management and analysis.
• Automated control: Through the gateway, automated control of building equipment can be achieved to improve the operating efficiency of the building.
• Remote monitoring: remote monitoring and management of building equipment is achieved to facilitate maintenance personnel to diagnose and repair faults.

Summarize

Gateways play a vital role in energy management systems and building management systems. Through gateways, we can achieve interconnection between different devices, centralized management and analysis of data, and automated control of the system. With the continuous development of IoT technology, the functions of gateways will become more and more powerful, combining energy management systems (EMS) with building automation systems (BMS) to discover opportunities to improve building performance in commercial, retail, education, government, healthcare and office fields. Combining EMS and BMS into one platform can break down barriers and bring us a more intelligent and efficient building management experience.
