Claim 0:
1. A computer-implemented method for analyzing
operations of a heating, ventilation, and air-conditioning (HVAC) system used to control a temperature of an indoor space, the computer-implemented method comprising:
implementing, using an analytics engine, a model of the HVAC system to perform discomfort-related operations comprising making a determination, based at least in part on operational data associated with the HVAC system and environmental data associated with the HVAC system, of causal relationships between discomfort parameters, outside air temperature parameters, and a discomfort source;
using the analytics engine and the model of the HVAC system to perform a classification operation comprising determining, based at least in part on a discomfort metric and the causal relationships, whether a source of the level of discomfort comprises a presence of a fault in the HVAC system or a load placed on the HVAC system; and
generating an alert responsive to determining that the source of the level of discomfort comprises the fault in the HVAC system, wherein the alert prompts a user of the HVAC system to take an action toward evaluating a need to repair HVAC system;
wherein the discomfort metric represents a level of discomfort experienced by an occupant of the indoor space.
