Assessing the simulation capability of the accurate engine in modelling massive construction elements

Simulation is often utilised in the regulatory assessment of building performance as in the case of the Australia’s Nationwide House Energy Rating Scheme (NatHERS). A recent government discussion paper (SOG-EE, 2012) proposes increased use of simulation as a method for building compliance assessment; however, responses to this document demonstrate a lack of confidence in the accuracy of the approved thermal assessment software used in the Scheme. Through empirical and intermodal comparisons, this paper examines the capacity of the computational engine. The examination highlights deficiencies in the input capabilities of the front end and the protocols governing its regulatory use and not in the engine itself.
