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
Weather Index (monthly means)
Adelaide had a more humid and colder February than the long-term average. The GHI was higher, and the wind speeds were comparable.
Energy Index (%)
The solar PV simulation output results were 3% up on the average. Cooling peak loads saw a 24% decrease in the 3-storey office, 25% in the 10-storey office, while the supermarket saw a 1% increase.
BRISBANE
Weather Index (monthly means)
Brisbane had a significantly less humid and colder February than average. The GHI was higher and the wind speeds were lower.
Energy Index (%)
The solar PV simulation output results were 8.2% higher than average, and all the building archetypes saw decreased cooling consumptions. Cooling peak loads were 53% and 50% higher for, respectively, the 3-storey office and the 10-storey office, while the supermarket saw a 11% increase.
CANBERRA
Canberra experienced a more humid February with temperatures comparable to the long-term average. The GHI was higher, while the wind speeds were lower, resulting in a 9.4% increase in the PV simulation.
All three building archetypes experienced higher cooling requirements compared to the average. While cooling peak loads were 19% and 13% lower (respectively) for the 3-storey office and the supermarket, the 10-storey building saw a 6% increase.
DARWIN
Darwin experienced a more humid and marginally warmer February compared to the long-term average. The GHI was lower and the wind speeds were also lower.
Compared to the long-term average, the solar PV simulation output results were 10% lower and all the building archetypes had marginally higher cooling consumption. Cooling peak loads were up 9% for the 3-storey office building and the 10-storey office building, while the supermarket saw a 1.3% increase.
HOBART
Hobart experienced a less humid and warmer February compared to the long-term average. The wind speed were higher throughout the day and the GHI was also higher.
Compared to the long-term average, the solar PV simulation output results were 2.4% higher and all the building archetypes had significantly higher cooling consumption. While the 3-storey office and the 10-storey office saw 21% and 23% lower cooling peak loads respectively, the supermarket saw a 31% decrease.
MELBOURNE
Melbourne had a more humid and colder February compared to the long term average. The GHI was marginally higher and the wind speeds were lower, resulting in a 0.5% decrease in the PV simulation.
All the building archetypes had lower cooling consumption compared to the long-term average. Cooling peak loads were down 38% and 37% for the 3-storey and the 10-storey office respectively, while the supermarket saw a 1% decrease.
PERTH
Perth experienced a less humid February with temperatures comparable to the long-term average. The wind speeds and the GHI were higher, particularly in the afternoons.
The solar PV simulation output results were 11% higher and while the office building archetypes experienced higher cooling consumptions the supermarket saw a slight decrease in cooling demand. Cooling peak loads were 18%, and 16% lower (respectively) for the 3-storey office and the 10-storey office, for the supermarket they were 6% lower.
SYDNEY
Sydney experienced a more humid and slightly colder February with temperatures comparable to the long term average, with colder mornings and warmer afternoons. The GHI and wind speeds were higher, leading to a 11% increase in the PV simulation output.
All the building archetypes experienced decreased cooling demand. Cooling peak loads were down 20%, 21% and 10% respectively for both the 3-storey and 10-storey offices as well as the supermarket.
