Claim 10:
11. A system comprising a processor and a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions readable by the processor system for analyzing operations of an HVAC system used to control a temperature of an indoor space, the system further comprising:
an analytics engine coupled to a memory, the analytics engine operable to implement a model of the HVAC system, the analytics engine and the model of the HVAC system operable 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 relationships between discomfort parameters, outside air temperature parameters, and a discomfort source;
a classification operation comprising determining, based at least in part on a discomfort metric and the relationships, whether a source of the level of discomfort comprises the presence of a fault in the HVAC system or a load on the HVAC system; and
generate 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.
