Preliminary energy model calibration

The eQUEST®/DOE-2.2 Refrigeration version software was used to generate a preliminary “calibrated” energy model. To determine the accuracy of the energy model, simulation results were compared to both the actual temperature and 15-minute interval electricity utility data. The purpose of this project was to illustrate that despite good alignment of the model to actual energy use, without a detailed audit and/or sub-metering information it is impossible to correctly predict actual end-use fractions (lighting, plug loads, compressor and condenser energy use). Without this information the calibration of the energy model is not reliable and accurately determining the impacts of energy efficiency measures is not possible.
