Abstract
A predictive controller for building equipment associated with a building includes one or more processing circuits configured to control electric energy used by the building equipment. The building equipment includes an electric energy using component. The one or more processing circuits are configured to utilize a predictive cost function to determine a first amount of the electric energy supplied from an energy grid source and a second amount of the electric energy supplied from a second energy source to the electric energy using component.
Claims20
A predictive controller for building equipment associated with a building, the predictive controller comprising one or more processing circuits configured to:
- control electric energy used by the building equipment, the building equipment comprising an electric energy using component;
- and
- use a predictive cost function to determine a first amount of the electric energy supplied from an energy grid source and a second amount of the electric energy supplied from a second energy source to the electric energy using component.
A unit of building equipment comprising:
- one or more powered components configured to use electric energy;
- and
- a predictive controller configured to use a predictive cost function to determine a first amount of the electric energy supplied from an energy grid source and a second amount of electric energy supplied from a second energy source to the one or more powered components.
A method for operating a unit of building equipment having one or more powered components that use electric energy, the method comprising:
- using a predictive cost function to determine a first amount of the electric energy supplied from an energy grid source and a second amount of the electric energy supplied from a second energy source to the one or more powered components;
- and
- operating the one or more powered components using the first amount of the electric energy supplied from the energy grid source and the second amount of the electric energy supplied from the second energy source.
