1. A system for estimating a building performance, the system comprising: a memory configured to store instructions comprising a method of estimating the building performance; a processor interactively linked to the memory, the processor configured to execute the method by: designating a plurality of building performance variables for estimating the building performance, the plurality of building performance variables including at least one occupant activity variable corresponding to an activity of an occupant of the building influenced by a type of a building; identifying an interaction network correlating a model building performance representative of the building performance with the designated plurality of building performance variables including the at least one occupant activity variable; selecting a known performance of at least one model structure as a proxy for the building performance; determining learned values for a plurality of initially unknown parameter values from the interaction network and the at least one model structure having the known performance; utilizing the learned values in the interaction network to estimate the building performance.
