About: Energy information management

Traditionally energy management equipment is associated with building automation (BAS) or building management systems (BMS). Energy management systems generate huge amounts of data about a building, from outside and inside air temperature, to carbon monoxide and humidity levels, each associated with the time of day, week, and year. These systems allow you to see what is going on in the building and to set complex schedules to control light and temperature based on the current information and instructions. They usually produce a record of energy use, but generally do not aggregate the data or allow you to see trends over time and location.
