     this paper presents an integrated energy performance modeling approach that considers heat and mass transfer through building envelope, hvac (heating, ventilation, and air conditioning) and refrigeration systems of a retail store building with limited measured data. the internal heat gains/losses were estimated based on an extended kalman filter. the simulation coupling strategy among room top units (rtus), refrigeration display cases and zones is based on the ping-pong coupling strategy. the integrated model was validated against measured data from june to august, 2011. the results show that temperature prediction is within the ±1.5°c error band and the rtu electricity energy use prediction is within the ±10% error band. the difference between measured and simulated annual electricity consumption from the refrigeration system is 3%. based on further analysis and diagnostics, deviations of model predictions from measured data were found to be partially due to the faults in the rtus. such deviation accounts for a 4% saving of the total building electrical energy consumption.
