SYSTEMS AND METHODS TO CONTROL ENERGY CONSUMPTION EFFICIENCY
First Claim
1. A controller for communicating with a building automation system, the controller comprising:
- a communications interface operable to exchange information contemporaneously in time between the controller and the building automation system, the exchanged information carrying data corresponding to operating parameters of equipment arranged in an HVAC system;
an optimization module having executable instructions for determining an operating efficiency of the HVAC system based on the present operating state of the equipment;
a simulation module having executable instructions for determining a predicted operating efficiency of the HVAC system computed from installation specifications provided with the HVAC equipment;
a comparison module in data communication with the optimization and simulation modules, the comparison module configured to determine whether the operating efficiency is below a desired threshold relative to the predicted operating efficiency; and
an adjustment module in data communication with the comparison module, the adjustment module configured to transmit instructions to the building automation system for changing at least one of the operating parameters for at least one piece of equipment of the HVAC system, the adjustment module further configured to process the instructions for changing in a self-learning aspect when the comparator, at a later time, determines the operating efficiency is below the desired threshold relative to the predicted operating efficiency.

Abstract
A controller is configured to exchange information with a building automation system and includes various executable programs for determining a real time operating efficiency, simulating a predicted or theoretical operating efficiency, comparing the same, and then adjusting one or more operating parameters on equipment utilized by a building'"'"'s HVAC system. The controller operates to adjust an operating efficiency of the HVAC system. An adjustment module utilized by the controller may modify the HVAC equipment parameters based on the likelihood that various HVAC equipment operates in parallel and on-line near its natural operating curve. In addition, the adjustment module may include a self-learning aspect that permits the controller to more efficiently make similar, future adjustments as needed.
