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.

*Readers will note the absence of Perth’s Exemplary Energy Index information for this month. Unfortunately, an instrument malfunction has resulted in us being unable to obtain solar radiation measurements for this site. Exemplary Energy is working towards a solution and we hope to re-publish our analysis (including coverage of the full history) in the coming weeks. In the meantime we will continue to provide Weather Index information for Perth, but energy and solar data will be unavailable.
BRISBANE
Weather Index (monthly means)
Brisbane had a significantly cooler and less humid December than average. The solar irradiation received was slightly lower, particularly in the morning, and the wind speed was mostly comparable to the average, with higher values during early mornings.
Energy Index (%)
The solar PV energy yield was 6% lower than average and the cooling energy consumptions of all the commercial building archetypes were slightly lower.
CANBERRA
Weather Index (monthly means)
Canberra experienced a December with temperatures and humidity comparable to the long term average. The solar insolation was slightly higher throughout the day, while the wind speed was significantly higher during the early mornings and at night.
Energy Index (%)
Solar PV energy yield was
9.5 % higher than average, and all the building archetypes had similar cooling requirements compared closely to the long term average across all zones, ranging from a 7 % reduction in cooling in the south-facing zone to a 4 % increase on the western side.
PERTH
Weather Index (monthly means)
Perth had a slightly warmer December with relative humidity that was comparable to the long term average. The average windspeed was considerably lower than average across the whole day.
As noted above, an instrument malfunction has resulted in an inability to obtain solar radiation measurements for this site. The Energy Index will be unavailable until that data becomes available. Exemplary Energy is working towards a solution and we hope to re-publish our analysis (including coverage of the full history) in the coming weeks.
SYDNEY
Weather Index (monthly means)
Sydney experienced a slightly cooler and more humid weather in December. The solar insolation and windspeed were considerably higher than the long term average, leading to a 32.7 % increase in the PV output simulation.
Energy Index (%)
All the building archetypes had slightly lower cooling consumption compared to the long term average. The north-facing and east-facing zones of the 10-storey building had 16 % lower cooling consumption, while for the west-facing and south-facing zones the cooling consumption was, respectively, 6 % and 19 % lower.
