Building Energy Management Systems

A Building Energy Management System (BEMS) is a computer-based system that automatically monitors and controls a range of building services, including air conditioning, ventilation, heating, lighting and other consumers of energy within the building or sometimes groups of buildings. Some systems also provide management of gas and water use.

There are a number of important benefits associated with use of a Building Energy Management system.

  1. It provides energy analysis, management and control information.
  2. It enables equipment, air conditioning, lighting etc to be switched on and off automatically.
  3. It optimises space heating within the building.
  4. It allows monitoring of equipment status and environmental conditions.

With the advent of the Smart Grid, these Building Energy Management Systems can help businesses better manage their electricity demand. With a varying price of electricity, the BEMS can program the system can turn on and turn off loads without sacrificing occupant safety, comfort, and productivity.
