Exemplary Weather and Energy (EWE) Index February 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 to 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.

ADELAIDE

Energy Index (%)

The solar PV simulation output results were 6.4% higher than the long-term average. The cooling peak load was lower than the long-term average for all archetypes (28.8%, 31.2% and 11.1% 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 model using our RTY data.

Adelaide experienced a comparably humid and cool February compared to the long-term average. The GHI was much higher while average wind speed was lower than the long-term average.

Weather Index



BRISBANE

Energy Index (%)

The solar PV simulation output results were 4.8% lower than the long-term average. The cooling peak load was 36.5%, 35.2% and 10.8% higher 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 model using our RTY data.

Brisbane experienced an overall warmer and more humid February than the long-term average. The GHI and wind speed were much lower than the long-term average.

The cooling peak load was 58.6%, 61.4% and 30.2% higher 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 model using our RTY data.

Hobart experienced a less humid and warmer February compared to the long-term average. The GHI was much higher and wind speed was slightly higher than the long-term average.

Weather Index



MELBOURNE

Energy Index (%)

The solar PV simulation output results were 9.9% higher than the long-term average. All archetypes saw a decrease in cooling peak load. The cooling peak load was 0.8%, 2.9%, and 21.6% 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 model using our RTY data.

Melbourne experienced a comparably humid and cooler February compared to the long-term average. The GHI was much higher than the long-term average while wind speed was lower.

Weather Index



PERTH

Energy Index (%)
