Exemplary Weather and Energy (EWE) Index March 2022

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.

Archetypical buildings and systems

3-storey office

10-storey office

Supermarket

5kW domestic PV system


*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. A separate issue has delayed the availability of data from our Canberra observation site, which has been updated on the 9th of May. Exemplary Energy is working towards a solution and we hope to re-publish our analyses (including coverage of the full history) in the coming weeks. In the meantime we will continue to provide Weather Index information for this Perth, but energy and solar data will be unavailable.

BRISBANE

Weather Index (monthly means)

Brisbane had a slightly colder and less humid March 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 23.2 % lower than average and the cooling energy consumptions of all the commercial building archetypes were slightly lower


CANBERRA

Weather Index (monthly means)

In Canberra, temperatures and humidity were mostly comparable to the long term average in March, with slightly higher minimum values and lower maximum. The solar insolation was slightly higher throughout the day, which caused the solar PV simulation output results to be 4 % higher.

Energy Index (%)

The 3-storey building had slightly higher cooling requirements, while the supermarket experienced a significant decrease in cooling consumption compared to the long term average.
The west-facing and north-facing zones of the 10-storey building had, respectively, 1 % and 5 % higher cooling consumption, while for the east-facing the consumption was 3.5 % higher and the south-facing zones experienced
2.5 % less cooling consumption.


PERTH

Weather Index (monthly means)

Perth had a more humid March with temperatures almost 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 significantly more humid weather in March. The solar insolation was higher, particularly in the afternoon, and the wind speed observations were higher than the long term average.

Energy Index (%)

The solar PV simulation output results were 9.1 % higher and all the building archetypes had lower cooling consumption compared to the long term average. The north-facing and west-facing zones of the 10-storey building had 10% lower cooling consumption, while the east-facing zone and the south-facing zone saw 31% less cooling consumption.
