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 significant more humid and colder September compared to the long-term average. The GHI was lower, and the wind speeds were overall comparable.
Energy Index (%)
The solar PV simulation output results were 17% lower than the historic average, and all the building archetypes had significant higher heating consumptions and lower cooling demand. Cooling peak loads saw 37% decrease in the 3-storey office and 36% in the 10-storey office, while heating peak loads were 57% and 42% higher in, respectively, the 3-storey and the 10-storey office.
BRISBANE
Weather Index (monthly means)
Brisbane had a slightly more humid September with temperatures comparable to the long-term average. The GHI was significantly lower, and the wind speeds were also lower throughout the day.
Energy Index (%)
The solar PV simulation output results were 22 % lower, and all the building archetypes saw decreased cooling consumptions, with the supermarket also experiencing lower heating demand. While cooling peak loads were 9.5%, 12%, and 6% lower for, respectively, the 3-storey office, the 10-storey office, and the supermarket, the heating peak loads saw a 12% and 2% decrease for, respectively, the 3-storey office and the supermarket, while the 10-storey office experienced a 19% increase.
CANBERRA
Weather Index (monthly means)
Canberra experienced a significant more humid September, with temperatures comparable to the long-term average. The GHI and wind speeds were lower, resulting in a 15% decrease in the PV simulation.
Energy Index (%)
All three building archetypes experienced lower cooling and higher heating requirements, with exception of the supermarket which had marginally lower heating demand. While cooling peak loads were 20% and 7.5 lower for, respectively, the 3-storey and the 10-storey office, heating peak loads were 3.5% lower for both the office archetypes.
DARWIN
Weather Index (monthly means)
Darwin experienced a more humid and warmer September compared to the long-term average. The GHI was lower during the morning and higher in the afternoon, with comparable wind speeds.
Energy Index (%)
Compared to the long-term average, the solar PV simulation output results were 5.8% lower and all the building archetypes had higher cooling consumption. Cooling peak loads were down 21% higher for both the office buildings, while the supermarket saw a 3% increase.
HOBART
Weather Index (monthly means)
Hobart experienced a significant more humid and slightly warmer September compared to the long-term average. The wind speed were slightly lower throughout the day and the GHI was also lower.
Energy Index (%)
Compared to the long-term average, the solar PV simulation output results were 24% lower and all the building archetypes had lower heating and cooling consumptions. While the 3-storey office saw 16% higher cooling peak loads and 16% lower heating peak loads, the 10-storey office experienced marginally lower cooling peak loads and 15% lower heating peak loads.
MELBOURNE
Weather Index (monthly means)
Melbourne had a significant more humid and slightly colder September. While the GHI was comparable in the morning, it dropped below the long-term average during the afternoon.
Energy Index (%)
The solar PV simulation output results were 12% lower and the building archetypes had lower cooling consumption and higher heating requirements compared to the long-term average. While cooling loads were down 10% and 4% for, respectively, the 3-storey and the 10-storey office, heating loads saw a 35 decrease for the 3-storey building and a 28% decrease for the 10-storey building.
PERTH
Weather Index (monthly means)
Perth experienced a marginally warmer and less humid September compared to the long-term average. The wind speeds were overall comparable, and the GHI was lower in the morning and higher in the afternoon.
Energy Index (%)
The solar PV simulation output results were 1.5% lower. All the three building archetypes experience significant higher heating consumptions and lower cooling demand. While cooling peak loads were 18.5%, 17%, and 8.5% higher for, respectively, the 3-storey office, the 10-storey office, and the supermarket, the heating peak loads saw a 35% and 28% decrease for, respectively, the 3-storey and the10-storey office, while the supermarket experienced a 97% increase.
SYDNEY
Weather Index (monthly means)
Sydney experienced a significant more humid weather in September, with temperatures comparable to the long-term average. The GHI was lower, which led to a 18% decrease in the solar PV simulations output, while the wind speeds were higher throughout the day.
Energy Index (%)
All three building archetypes experienced significant higher heating consumptions and lower cooling demand. Cooling peak loads were down 15% for the 3-storey office and the supermarket, while the 10-storey office saw a 13% decrease. On the other hand heating peak loads were up, respectively, 64% and 61% for the 3-storey and 10-storey building, and 60% higher for the supermarket.
