The paper introduces a hybrid modelling approach that enhances the accuracy and usability of physics-based energy simulation for existing buildings. The approach leverages measured zone air temperature data streams{\textemdash} increasingly available from smart thermostats{\textemdash}to derive difficult-to-obtain input parameters for internal thermal mass and infiltration airflow rates. It does so using a reformulated inverse heat balance algorithm. We implemented the inverse algorithms in EnergyPlus and used LBNL{\textquoteright}s Facility for Low Energy eXperiments (FLEXLAB) for demonstration and validation.
