An EMS is a centralized control system that takes over manually controlled functions. It can be a simple unit connected to one or two pieces of equipment, or it can be more complex and control lights and equipment throughout your facility. EMS systems can monitor total building loads and turn on or off appropriate equipment. EMS systems also analyze outside and inside temperatures and regulate the HVAC system in your building. EMS systems could save 5 percent to 30 percent on kwh and energy charges, and can reduce your demand charges as well.
Results vary according to hours of operation and type of equipment controlled.
EMS systems could deliver simple paybacks of two to four years.
