Energy Management System (EnMS / EMS)
An energy management system is the combination of metering, software and processes used to monitor, control and continuously improve a site's energy use. A formal EnMS often follows the ISO 50001 standard.
An EnMS gives visibility of energy by line, area and utility, identifies waste, and tracks the impact of efficiency measures. It pairs hardware (meters, sub-meters, power monitoring) with analytics software and a management process. ISO 50001 provides a recognised framework for running an EnMS and is one route to ESOS compliance in the UK.
