The primary function of an EMS is to automatically turn off equipment when it is not needed. The heart of an energy management system is a programmable electronic control, which accepts instructions on how the facility is to operate and communicates those instructions to the equipment that is to be controlled. EMS systems can now be managed online from remote locations. Continuing advances in technology have made EMS systems cost-effective for smaller facilities.
Better Control Reduces Energy Use
Energy management systems are very versatile. They are capable of maintaining different schedules for different pieces of equipment with unique schedules for each day of the week. Systems can be programmed to reflect occupancy levels, shift schedules, type of work performed, and other variables that affect the need for heating and cooling. EMS technology can be used to relax temperature set points when a building is unoccupied by alternating use of heating and air conditioning rather than turning the systems off completely. This approach controls humidity, protects the building contents, and prevents overheating and freezing. National Grid assists commercial, industrial, and municipal customers by assessing EMS needs and providing incentives for qualifying opportunities. We can also arrange for turnkey installation. Contact your National Grid representative for further information on this program or for assistance in applying for these incentives.
