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 slightly less humid and colder July compared to the long-term average. The GHI was lower, and the wind speeds were overall lower, particularly during the afternoons.
Energy Index (%)
The solar PV simulation output results were 10% lower than the historic average. For the 10-storey building, heating consumption was 20% higher in the south-facing and west-facing zones, while the east-facing and north-facing zones saw, respectively, 34% and 30% higher heating loads. On the other hand, the cooling consumption was roughly 40% lower for the east-facing and south-facing zones, while cooling in the west-facing zone was 6% higher and in the north-facing zone was 8% lower.
BRISBANE
Weather Index (monthly means)
Brisbane had a more humid July with temperatures comparable to the long-term average. The GHI was lower, and the wind speeds were also lower throughout the day.
Energy Index (%)
The solar PV simulation output results were 19 % lower, and both office archetypes saw increased heating and decreased cooling consumption, while the supermarket had less heating and cooling requirement. While cooling peak loads were mostly comparable to the long-term average for the supermarket, the 3-storey and 10-storey office saw, respectively, a 6% and 12% decrease relative to the historic average. On the other hand, heating peak loads saw a 20% decrease for both the office archetypes and a 13% decrease for the supermarket.
CANBERRA
Weather Index (monthly means)
Canberra experienced a slightly less humid and warmer July comparable to the long-term average. The GHI was slightly lower, and the wind speeds were also higher, particularly in the morning.
Energy Index (%)
The solar PV simulation output results were 1.6 % higher than average. All three building archetypes experienced marginally lower heating and higher cooling requirements compared to the long-term average.
DARWIN
Weather Index (monthly means)
Darwin experienced a slightly colder and more humid July compared to the long-term average, with higher wind speeds and GHI.
Energy Index (%)
Compared to the long-term average, the solar PV simulation output results were 0.8% lower and the office building archetypes had lower cooling consumption. Cooling peak loads were down 14% for the 10-storey office building and the supermarket, and 13% lower for the 3-storey office archetype.
HOBART
Weather Index (monthly means)
Hobart experienced a slightly more humid and slightly colder July compared to the long-term average. The wind speed were slightly lower and the GHI was higher, leading to a 9.5 % increase in the solar PV simulation output results.
Energy Index (%)
All the building archetypes had higher heating consumptions and lower cooling requirements compared to the long-term average. The west-facing, south-facing, and east-facing zones of the 10-storey building had roughly 16% higher heating consumption, while the north-facing zone saw 14% more heating consumption. Cooling peak loads were comparable to the long-term average for all archetypes, while heating peak loads were 9.4% lower for the 3-storey building, 8.5% lower for the 10-storey building and 3.6% lower for the supermarket.
MELBOURNE
Weather Index (monthly means)
Melbourne had a slightly colder and more humid July compared to the long-term average. The wind speeds were lower, particularly in the afternoon, and the GHI was slightly lower.
Energy Index (%)
The solar PV simulation output results were 8.8% higher and the building archetypes had lower cooling consumption and higher heating requirements compared to the long-term average. For the 10-storey building, heating consumptions were 25% lower in the west-facing, north-facing and south-facing zones, while the east-facing saw a decrease of 18%. On the other hand, the cooling consumption was roughly 14% lower for the north-facing and west-facing, while the west-facing and south-facing zones saw a 70% relative decrease.
PERTH
Weather Index (monthly means)
Perth experienced a warmer and less humid July compared to the long-term average. The wind speeds were overall higher, and the GHI was lower.
Energy Index (%)
The solar PV simulation output results were 11% lower. For the 10-storey building, heating consumptions were 10% lower in the west-facing and south-facing zones, while the east-facing zone saw an increase of 45 % and the north-facing zone had 22% higher requirements. While cooling peak loads were mostly comparable to the long-term average, heating peak loads were down 23% for the 3-storey and the supermarket, and 20% lower for the 10-storey buildings.
SYDNEY
Weather Index (monthly means)
Sydney experienced a significant more humid weather in July, with temperatures comparable to the long-term average. The GHI was significantly lower, which led to a 39% decrease in the solar PV simulations output, while the wind speeds were higher throughout the day.
Energy Index (%)
All three building archetypes experienced higher heating consumption. In particular, in the 10-storey building, heating consumption was, respectively, 70% and 44% higher in the east-facing and north-facing zones, while the west-facing and south-facing zones saw an increase of 5%. Cooling peak loads were down 14% for the 3-storey office and 10% for the 10-storey office. On the other hand heating peak loads were down, respectively, 7% and 4% for the 3-storey and 10-storey building, and 18% higher for the supermarket.
