Honegger, NicoleLiu, XiaoyuFinal project for ENCE602: County Plan for Energy Efficiency and Conservation (Fall 2016). University of Maryland, College Park.Energy Management Systems (EMS) are a type of software that monitor the energy consumption in buildings. Its purpose is to minimize costs by monitoring energy consumption and optimizing energy use. EMS has become increasingly popular in the past fifteen years and is used primarily by businesses to save money by tracking and reducing energy consumption in their buildings. It can also be used in state and local government facilities to measure the energy consumption. While a few software options are available, each product has unique features. This paper reviews different energy management systems based on their features and functionalities to provide recommendations on the best-fit system for the Anne Arundel County.en-USTechnical Report
