Exemplary Weather and Energy (EWE) Index June 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 21.8% lower than the long-term average. The heating peak load was higher than the long-term average for all archetypes (8%, 6.6% and 13.1% for 3-storey office, 10-storey office and supermarket respectively). 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 cooler June compared to the long-term average. The GHI and wind speed were much lower than the long-term average.

Weather Index



BRISBANE

Energy Index (%)

The solar PV simulation output results were 12.7% higher than the long-term average. Both Cooling and Heating peakload was lower than the long-term average. The cooling peak load was 30.8%, 33.1% and 11.7% lower and the heating peak load was 39.4%, 37.4%, and 29.3% lower for the 3-storey office, 10 storey office and supermarket respectively. 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.

Brisbane experienced comparably warmer and less humid June than the long-term average. The GHI was much higher while wind speed was similar to the long-term average.

Weather Index



CANBERRA

Energy Index (%)

The solar PV simulation output results were 6.5% higher than the long-term average. The heating peak load was 4.5%, and 32.5% higher for the 3-storey office and 10 storey office while 0.3% lower for supermarket respectively. 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.

Canberra experienced a more humid and cooler June compared to the long-term average. The GHI was similar but wind speed was higher than the long-term average.

Weather Index



DARWIN

Energy Index (%)

The solar PV simulation output results were 4.6% lower than the long-term average. The cooling peak load was higher than the long-term average for all archetypes (4.4%, 6.8% and 0.8% for 3-storey office, 10-storey office and supermarket respectively). 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.

Darwin experienced a slighlty more humid of normal temperatures June compare to the long-term average. The GHI and wind speed were slightly lower than the long-term average.

Weather Index



HOBART

Energy Index (%)

The solar PV simulation output results were 12.9% lower than the long-term average. The heating peak load was lower than the long-term average for all archetypes (25.9%, 21.5% and 26.6% for 3-storey office, 10-storey office and supermarket respectively). 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.

Hobart experienced a slightly more humid and warmer June compared to the long-term average. The GHI was slightly higher while wind speed was lower than the long-term average.

Weather Index



MELBOURNE

Energy Index (%)

The solar PV simulation output results were 11.1% lower than the long-term average. The heating peak load was higher than the long-term average for all archetypes (25.9%, 29.4% and 13.0% for 3-storey office, 10-storey office and supermarket respectively). 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.

Melbourne experienced a more humid and slightly cooler June compared to the long-term average. The GHI was almost similar to the long-term average.

Weather Index



PERTH

Energy Index (%)

The solar PV simulation output results were 0.3% lower than the long-term average. Compare to long term average, the cooling peak load was 9.1% and 6.3 % higher for 3-storey office and 10-storey office while 6.2% lower for supermarket. 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.

Perth experienced a more humid and warmer June compared to the long-term average. The GHI was slightly higher while wind speed was lower than the long-term average.
