Exemplary Weather and Energy (EWE) Index November 2024

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.

ADELAIDE

Energy Index (%)

The solar PV simulation output results were 3.5% lower than the long-term average. The cooling peak load was significantly lower than the long-term average for 3- and 10-storey office buildings, by 20.1% and 55.2%, respectively, and slightly lower for supermarkets, at 5.5%. 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 more humid and warmer November compared to the long-term average. The GHI was similar while wind speed was lower than the long-term average.
