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.

BRISBANE
Weather Index (monthly means)
Brisbane had a warmer and more humid April than average. The solar irradiation received was lower, and the wind speed observations were also lower throughout the day.
Energy Index (%)
The solar PV simulation output results were 10.8 % lower than average and the cooling energy consumptions of all the commercial building archetypes were higher. The north-facing and west-facing zones of the 10-storey building had 20% higher cooling consumption, while the east-facing zone and the south-facing zone saw, respectively, 27% and 44% more cooling consumption.
CANBERRA
Weather Index (monthly means)
In Canberra, temperatures were mostly comparable to the long term average in April, with slightly higher minimum values and lower maximum. The humidity was significantly higher and the solar insolation was lower throughout the day, which caused the solar PV simulation output results to be 13.9% lower.
Energy Index (%)
All the building archetypes experienced lower heating and cooling requirements compared to the long term average.
For the 10-storey building, heating consumptions were, respectively, 30% and 11% lower in the west-facing and north-facing zones, 14% lower for the south-facing zone, while the east-facing zone saw an increase of 50%. On the other hand, the cooling consumptions were 18% lower for the north-facing a south-facing zones, while the west-facing and east-facing zones saw, respectively, a 14% and 22% decrease.
PERTH
Weather Index (monthly means)
Perth experience temperatures and humidity mostly comparable to the long term average in April. The windspeed observations were slightly higher throughout the day, and the solar insolation was also higher.
Energy Index (%)
The solar PV simulation output results were 2.3% higher and the building archetypes had slightly lower cooling consumption compared to the long term average.
SYDNEY
Weather Index (monthly means)
Sydney experienced a significantly more humid weather in April, with significantly higher mean minimum temperatures, but comparable averages. The solar insolation was lower and the wind speed observations were comparable to the long term average.
Energy Index (%)
The solar PV simulation output results were 22.3 % lower and all the building archetypes had lower cooling consumption compared to the long term average. The north-facing, west-facing, and east-facing zones of the 10-storey building had around 13% lower cooling consumption, while the south-facing zone saw 5% less cooling consumption.
