Abstract
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.
Claims15
A method for energy management, the method comprising:
- collecting energy consumption data for a site during a period of time using one or more energy consumption meters;
- identifying data clusters within the energy consumption data, the data clusters indicating a status of energy consumption at the site;
- categorizing the data clusters in the period of time;
- analyzing the data clusters;
- assigning one of a plurality of energy consumption classifications to the period of time;
- identifying the period of time as being one of:
- a normal period of time and an abnormal period of time, with respect to an actual energy consumption during the period of time;
- controlling at least one device to manage the energy consumption in response to an identification of an abnormal period of time;
- identifying a first data cluster corresponding to normal running hours;
- identifying a second data cluster corresponding to normal closed hours;
- calculating a first mean energy consumption value for the first data cluster and a second mean energy consumption value for the second data cluster;
- and
- calculating a ratio of the first mean energy consumption value to the second mean energy consumption value.
A system for energy management, the system comprising:
- at least one energy consumption meter;
- a controller having a processor and a memory component, the controller being in communication with the at least one energy consumption meter;
- wherein the processor is configured to:
- collect energy consumption data for a site during a period of time using the at least one energy consumption meter;
- identify data clusters within the energy consumption data, the data clusters indicating a status of energy consumption at the site;
- categorize the data clusters in the period of time;
- analyze the data clusters;
- assign one of a plurality of energy consumption classifications to the period of time;
- identify the period of time as being one of:
- a normal period of time and an abnormal period of time, with respect to an actual energy consumption during the period of time;
- control at least one device to manage the energy consumption in real time in response to an identification of an abnormal period of time;
- identify a first data cluster corresponding to normal running hours;
- identify a second data cluster corresponding to normal closed hours;
- calculate a first mean energy consumption value for the first data cluster and a second mean energy consumption value for the second data cluster;
- and
- calculate a ratio of the first mean energy consumption value to the second mean energy consumption value.
