The contribution of simulation to the building tuning process for 2 Victoria Avenue

2 Victoria Avenue is the first building in WA to achieve a 6 Star Green Star rating and a 5 Star NABERS Energy rating. Over the first 12 months of operation, it was found that the predicted performance of the building was within 3% of the measured overall building usage. Furthermore, it showed the efficacy of the ‘what-if scenarios’ in identifying and mitigating risk to building performance. Finally, the review also shows the effectiveness of building tuning, with marked energy performance improvements occurring steadily after practical completion of the building. A modelling process was undertaken for the building, where predicted energy consumption levels for each component of the building’s services were derived and compared to the actual building performance.This paper presents an overview of the modelling process, its influence on design, the commissioning and tuning process and finally reviews the overall building energy performance against industry benchmarks.
