Planning your building controls and Building Energy Management System (BEMS)

The most efficient BCS/BEMS is one where all aspects of control are closely integrated with one another and decisions are made based on interactions between sub-systems, e.g. heating interlocked with cooling, or ventilation and shading initiated by lighting control system occupancy sensors.

building controls industry association Planning your building controls and Building Energy Management System (BEMS) Integration of controls 1. Considerations for Integration 2. Communications The most efficient BCS/BEMS is one where all aspects of control are closely integrated with one another and decisions are made based on interactions between sub-systems, e.g. heating interlocked with cooling, or ventilation and shading initiated by lighting control system occupancy sensors. It is important that the equipment selected should provide the correct physical interface(s) and support open protocols to facilitate integration between systems and sub-systems. • • • • • • • • Are there any areas that should be isolated from integration, e.g. operating theatres, laboratories, computer equipment rooms? If retrofitting, is the legacy equipment worth keeping? (or is it beneficial to replace it as part of a new, integrated system?) Is the system going to be installed as separate “vertical functions” (e.g., lighting, BMS, energy monitoring) or will it be room-focussed where all functions required are integrated as a single system within that space? Demand-based control at room level is proven to provide the highest level of occupant comfort, delivered in the most energy-efficient way. • Does any legacy equipment have the facility to communicate or is this available as an add-on? (e.g., BACnet or Modbus interface) Can all systems or controllers communicate on the same physical network...
