US Patent 10921762 Energy management system and method

A method for energy management include steps of collecting data during a period of time, identifying data clusters within the data, categorizing the data clusters in the period of time, analyzing the data clusters, and assigning a classification to the period of time. Real time data can be compared to scheduled performance. Real time notifications can be provided to a user where energy is being used inefficiently. Energy efficiency of meters within a site can be ranked to identify meters where energy is being used inefficiently. A system is also provided for performing the method of the present disclosure.
