Description:

Energy management and information systems are software tools that interface with a building to manage and control energy use. In addition to benchmarking and utility tracking (like Energy Star’s Portfolio Manager), building automation systems (BAS) are a common form of EMIS. A BAS is a computer based tool that allows the facility manager to control everything from HVAC to lighting to security systems. The Department of Energy has extensive information on EMISs through the Better Buildings Program.
