The new BEMS Performance Specification, which has been produced by the Technical Working Group, is now available on the BCIA website.
Well done to all of the Technical working group on this well needed specification!
A building energy management system (BEMS), may also be known as Building Automation System (BAS), Building Management System (BMS) or other similar terms.
A BEMS may consist of a number of intelligent controllers located in control panels or equipment with factory fitted intelligent controls integrated to form an intelligent system.
This system will control the heating, cooling and ventilation systems. Metering solutions may be integrated using communication protocols or by hard-wired connections.
Other third party devices should be connected to the BEMS using BACnet or other common protocols.
An appropriate user interface should be incorporated so as to allow user interrogation, adjustment and display of system settings and conditions. All peripheral devices shall be supplied by a reputable controls manufacturer and these will include sensors, OEM Manufactured equipment, valves, control actuators and variable speed drives.
The BEMS shall be supplied, configured and commissioned by a specialist controls company who are members of the Building Controls Industry Association.
Membership of the BCIA means they have ready access to the latest standards, technology advancements and training.
Most BEMS manufacturer’s equipment today offers cloud based technologies that allow additional services to be provided such as Energy Analysis, Asset Management, Remote Fault Diagnosis, and Predictive Maintenance, etc.
The controls system and BEMS should be designed and installed to comply with the standards of EN15232.
The BEMS system should be designed to operate the plant to ensure the most energy efficient operation of the connected building services whilst maintaining occupant comfort.
The most energy efficient systems utilise demand control techniques to ensure services are only deployed when needed.
There are many studies that have proven maximum occupier comfort and productivity is best achieved if due consideration is given to human wellbeing during the design.
