The Exemplary Real Time Year weather files (RTYs), current Reference Meteorological Year files (RMYs) and Ersatz Future Meteorological Years (EFMYs) used for these monthly simulations are available for purchase. This will allow clients to simulate their own designs for energy budgeting and monitoring rather than rely on analogy with the performance of these archetypical buildings and systems. Especially in mild months, small differences in energy consumptions can result in large percentage differences. Solar irradiation data courtesy of Solcast.

| -20.6% | +2.3% | -17.4% | -3.2% | -16.9% | +51.0% |
| Solar PV | |||||
| +2.1% |
The solar PV simulation output was 2.1% higher than the long-term average. The cooling peak load was higher than the long-term average for 3-storey and 10-storey office buildings, by 19.9% and 34.7%, respectively, and lower for the supermarket, at 2.5%. It should be noted that peak load results are highly sensitive to the particular building and HVAC design and settings – it is more appropriate to evaluate those results from a bespoke building model using our RTY data.
Adelaide experienced a less humid June overnight with similar temperature to the long-term average. The GHI was very close to the long-term average and the wind speed was higher in the early morning.
