Claim 9:
10. A system, comprising:
a building automation system configured to control a chiller; and
a control system configured to:
operate the chiller over a range of operating capacities of the chiller;
calculate a first efficiency value of the chiller at a first operating capacity of the chiller;
calculate a plurality of second efficiency values of the chiller at a plurality of second operating capacities of the chiller;
separate samples comprising the first efficiency value and the plurality of second efficiency values into a plurality of bins, wherein each bin of the plurality of bins represents a portion of the range of operating capacitates of the chiller;
generate an efficiency curve for the chiller based on the samples in the plurality of bins; and
communicate the efficiency curve to the building automation system.
