Use of calibrated building performance simulation models in energy auditing

Ali Dasmeh, H. Burak Gunay

Abstract: This paper first presents a review of fourteen commercial building energy audits conducted in Ottawa, Canada. Of them, we identified that only one of these audits used an uncalibrated building performance simulation model. Many of them relied on heating and cooling degree day models to develop recommendations about the top energy conservation measures (ECMs) for building retrofits. Subsequently, a calibrated building performance simulation-based approach by using Autodesk Insight 360 platform was applied in one of the fourteen buildings to rank the list of same ECMs. We compared them to those that were identified in the energy audit report and discussed the underlying reasons behind the discrepancies between them. The results indicate that the use of calibrated building performance simulation models in energy auditing practice results in substantially different energy savings estimates and different building retrofit scenarios.
