Exemplary Energy is pleased to announce that our weather and climate datasets are now available through our new sales portal.
We are currently offering data across 11 key sites (8 capital cities, plus Alice Springs, Mildura and Thredbo), providing coverage of all NCC climate zones in the Australian Climate Data Bank (ACDB) and Energy Plus Weather (EPW) formats. An extension to 250 sites across Australia will be available in the coming weeks with the full 69 NatHERS Climate Zones being given priority, including versions complete with precipitation data.
Our data incorporates meteorological observations up to the end of 2022, and avoids the well understood but serious flaws present in the data which the CSIRO continues to publish.
We are pleased to note three major improvements in this latest release:
- Inclusion of observations to the end of 2022;
- Incorporation of precipitation, derived from half-hourly observations when available and from the results of our advanced machine learning tool “Anaconda” in other cases; and
- Vastly improved estimates of cloud cover compared to previous versions.
We are also offering a range of data types including Real-Time Years (RTY), Reference Meteorological Years (RMY) with 33-year and 15-year basis periods1, Industry Standard Meteorological Years (ISMY, produced as a corrected version of CSIRO’s 1990-2016 RMY data), eXtreme Meteorological Years for PV (XMY_PV) and Ersatz Future Meteorological Years (EFMY).

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.

Energy Index (%)
The solar PV simulation output results were 10.2% higher than the long-term average. Heating energy consumption was 12.3% and 23.9% higher for the 10-storey office and 3-storey office respectively. Cooling energy consumption was 34.2%, 29.4% and 20.4% lower for the 10-storey, 3-storey offices and the supermarket, respectively.
