Claim of US Patent No. 10,461,954

1. An equipment-sequencing processing device configured to execute a method for sequencing HVAC equipment in an HVAC system, the method comprising:acquiring a plurality of inputs including historical weather data and data representing at least one future time period of interest;
determining energy efficiencies for the HVAC equipment;
acquiring weather prediction data associated with the at least one future time period of interest;
using the inputs, energy efficiencies and weather prediction data, computing an expected future load for the HVAC equipment;
using the inputs, energy efficiencies, weather prediction data and expected future load, employing an analytical computational model to determine predicted energy efficiencies for the HVAC equipment;
determining an initial sequence of operation of the HVAC equipment configured to provide an optimized energy efficiency for the HVAC system;
determining the availability of the HVAC equipment included in the initial order based on an operating status for one or more of the HVAC equipment;
determining, based on the determination of availability of the HVAC equipment, a final sequence of the HVAC equipment; and
providing the final sequence to a building automation system for controlling the HVAC system in accordance with the final sequence.
