Energy Management Systems (EMS) provide data storage, trending, monitoring, reporting and analysis functionality for meter and other device data associated with WAGES (Water, Air, Gas, Electricity and Steam) energy usage and electrical power quality. 

An EMS - typically a software solution - allows facility, building and energy managers to gather long term data and insight that allows them to make more informed decisions about energy activities across their facility or sites.

This green paper is aimed at Consultants, Sustainability Managers, Facility Managers, Energy Managers, Portfolio Managers, Electrical Contractors and Mechanical Services Contractors involved in commercial buildings and facilities. It provides an overview of the features and functionality of the system as related to energy usage improvement outcomes.
