N2 - This paper presents a comparative analysis on the weather parameters of 5 different datasets used in Australia for the same location and on-site measured data, including their performance difference with respect to building energy simulation results of an existing case study, calibrated against actual annual energy consumption. The simulation results show that the difference in annual and seasonal (hot and cold) energy consumption can vary by up to ±7% (20kWh), ±34% (47.8kWh) and ±29% (36.2kWh) respectively as a function of the weather data used for the same location. Consequently, having some accurate onsite measurements is critical for choosing the appropriate weather data set for design purposes and accurate prediction of energy simulation results.
