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 an inability 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 this site, but energy and solar data will be unavailable.
BRISBANE
Weather Index (monthly means)
Brisbane had a cooler but more humid November than average. The solar irradiation received
was generally lower, particularly in the morning, and the wind speed was considerably lower throughout the day.
Energy Index (%)
The solar PV simulation output results were 27.3% lower than average and the cooling energy consumptions of all the commercial building archetypes were also lower. In particular, for the north-facing and the west-facing zones of the 10-storey building the cooling consumption
was, respectively, 20 % and 37 % lower, while for the east and south-facing zones it was 17 % lower.
CANBERRA
Weather Index (monthly means)
Canberra saw a slightly cooler but more humid weather in November. The solar insolation was mostly comparable to the long term average, while the wind speed was significantly higher, particularly in the early morning and late night.
Energy Index (%)
The solar PV simulation output results were
14.2 % higher than average and, while the the office building archetypes had slightly lower cooling consumption, the supermarket had considerably less cooling requirements.
The north-facing and south-facing zones of the 10-storey building had, respectively, 18 % and 24 % lower cooling consumption, while for the west-facing and east-facing zones the cooling consumption was 12 % lower.
PERTH
Weather Index (monthly means)
Perth had a slightly cooler and more humid November than average. The windspeed observations were also considerably lower throughout the whole day.
SYDNEY
Weather Index (monthly means)
Sydney experienced a slightly cooler and more humid weather in November. The solar insolation and the wind speed were slightly higher than the long term average, leading to a 4.5 % increase in the PV output simulation.
Energy Index (%)
While the office building archetypes had slightly lower cooling consumption, the supermarket had considerably lower cooling and heating requirements. The north-facing and south-facing zones of the 10-storey building had, respectively, 17 % and 23 % lower cooling consumption, while for the west-facing and east-facing zones the cooling consumption was, respectively,
9 % and 12 % lower.
