Optimising existing BMS software strategies and hardware devices can improve the energy-efficient control of your building, without detriment to operational and environmental conditions.
Core problems with BMS systems
Building Management Systems (BMS) are the ‘brains’ behind the effective control of heating, ventilation and air conditioning (HVAC) systems in many commercial and industrial buildings.
Typically, a BMS will control 50 – 75% of a building’s total energy consumption and, if the BMS is operating as designed, comfortable internal conditions will be maintained without wasting energy.
However this situation very rarely occurs for the following reasons:
- The BMS was never effectively designed to minimise energy consumption in the first place
- Legacy faults remain on the system post commissioning
- System set-points and key control parameters are adjusted or over-ridden by internal staff and contractors
- Sensors, actuators and other devices fail, or are out of calibration
- The BMS is not modified when change of use of internal space occurs
By improving a poorly managed BMS, you can typically reduce your energy consumption by up to 20%.
How can CMR help?
Our consultants will carry out an initial study of your BMS design concepts and identify improvements, based on energy efficiency best practice.
The next step is to compare the revised design concepts with your existing software and hardware and develop a schedule of required modifications, re-calibration, upgrades and replacement.
The final stage is to implement any agreed changes, including advice on ongoing measurement and validation of the savings achieved.
