Energy Management Systems

Energy Management Systems (EMS), also known as Building Management Systems (BMS), are computer-based control systems that are installed  to help manage the facility’s mechanical and electrical equipment so they work in harmony to ensure all are running at the peak of efficiency.

A BMS system has both hardware and software that is used to control the building’s electrical equipment such as lighting, HVAC, ventilation, fire and security systems, and large power sources.  The main function of a BMS unit is to manage the temperature, CO2 levels and humidity in the building.  The system will compensate for these changes by adjusting some other building function.  Having a well-configured BMS system can have a tremendous impact on a company’s energy costs.

Building Management Systems for Lighting

A Building Management System (BMS) used for lighting purposes can greatly reduce the amount of energy wasted on unnecessary lighting.  The type of space you are in will change the type of controls that are available (i.e. private office – no windows, private office – windows, hallways, washrooms, meeting rooms).

Controls used for lighting:

  • Daylight Harvesting – window blinds open letting in natural light – light level in the room
  • Occupancy Control (first occupant / last occupant)
  • Task Tuning
  • Personal Control
  • Scheduling
  • Load Shedding
