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 slightly warmer and less humid February than average. The solar irradiation received was lower, and the wind speed observations were mostly comparable throughout the day.
Energy Index (%)
The solar PV simulation output results were 24% lower than average and the cooling energy consumptions of all the commercial building archetypes were slightly higher
CANBERRA
Weather Index (monthly means)
In Canberra, temperatures and humidity were mostly comparable to the long term average in February, with slightly higher minimum values. The solar insolation was slightly higher throughout the day, which caused the solar PV simulation output results to be 3.3 % higher.
Energy Index (%)
All the building archetypes had higher cooling requirements compared to the long term average.
The west-facing and north-facing zones of the 10-storey building had 15 % higher cooling consumption, while for the east-facing and south-facing zones the cooling consumption was, respectively, 14 % and 7.5 % higher.
PERTH
Weather Index (monthly means)
Perth had a slightly warmer and less humid February comparable to the long term average. The windspeed observations were considerably lower throughout the 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 cooler and more humid weather in February. The solar insolation was slightly higher, particularly after noon, and the wind speed observations were lower than the long term average.
Energy Index (%)
The solar PV simulation output results were 19.3 % higher and all the building archetypes had substantially lower cooling consumption compared to the long term average. The north-facing and south-facing zones of the 10-storey building had 22 % lower cooling consumption, while for the east-facing zone the cooling consumption was 17 % lower and the west-facing zone saw 16 % less cooling consumption.
