Three case studies using building simulation to predict energy performance of Australian office buildings

This paper compares the energy performance of three office buildings as predicted by building simulation (using only the information typically available at the design stage) with the measured energy consumption of the same buildings in operation for a twelve-month period. The buildings are located in Canberra, Australia. The study was limited to three buildings in a single climate, but it aimed to identify factors that caused discrepancies between the energy performance of an office building as typically predicted in the design stage and the energy performance of those buildings in operation. Once identified these factors will be used as the basis for more detailed investigations.
