How is the industry baseline for performance determined?
The following benchmarks are a result of a review of 110 retail centres by HFM Asset Management on behalf of Water Corporation and Property Council of Australia. The target group of retail buildings are those with a gross lettable area (GLA) greater than 5000 m2 and with available water consumption data.
The results are used to determine the best-practice water use performance for water-cooled and air-cooled retail buildings. The industry benchmark is reviewed every 2 years to ensure best practice water use within retail buildings. Read the full report here.

How to calculate your water use benchmark
To measure your water use performance against the industry baseline for shopping centre water use, calculate your water use benchmark;
Divide your annual water use (based on your reading year - contact us if you need the data) by your gross lettable area retail (GLAR).
Calculation: annual water use/GLAR = your performance in kilolitres per square metre per year (kL/m2(GLA)/annum)
