Abstract:
A method for operating HVAC equipment includes obtaining building data for each of a plurality of time steps. The building data relates to resource usage of HVAC equipment. The method also includes calculating a recursive residual for each of a plurality of overlapping time periods using the building data. Each overlapping time period includes a subset of the plurality of time steps. The method also includes, for each of the plurality of time steps, calculating a metric based on the recursive residuals for overlapping time periods that end on or before the time step and automatically detecting a change in static factors for one or more buildings served by the HVAC equipment by comparing the metrics for the plurality of time steps based on a statistical property of the metrics.

Claim (Index 1):
A budding management system comprising:\n a plurality of sensors measuring a physical state or condition and generating sensor data indicating the physical state or condition measured by the plurality of sensors; and a controller configured to:\n use first sensor data from the plurality of sensors collected during a first time period to generate one or more first model coefficients for an energy usage model for HVAC equipment; \n use second sensor data from the plurality of sensors collected during a second time period to generate one or more second model coefficients for the energy usage model; \n generate a test statistic based on a difference between the first model coefficients and the second model coefficients and compare the test statistic with a critical value; and \n automatically identify a change in energy usage of the HVAC equipment in response to the test statistic exceeding the critical value.
