HVAC Benchmarking with Calculating Cool

Reduce your building's heating, ventilation and air-conditioning energy use by up to 40 per cent with Australia’s first of a kind HVAC (Heating, ventilation, and air conditioning) benchmarking tool.

The total energy used by HVAC in non-residential buildings equates to an incredible 9 per cent of the electricity produced in Australia, and nearly 4 per cent of the nation's greenhouse gas emissions. In summer, 50 per cent of peak electricity demand can be driven by HVAC in commercial office buildings. Heating, ventilation and air-conditioning (HVAC) generally accounts for 40–60 per cent of energy costs in commercial office buildings.

Calculating Cool is a free, online benchmarking tool that provides users with a simple yet effective way to find out how efficient their building's heating, ventilation and air conditioning systems are, and identify areas for improvements – visit the Calculating Cool website to try it today.

How it works

Calculating Cool uses a combination of quantitative and qualitative (or attribute) data inputs to measure HVAC energy efficiency and the potential for improvements in areas including maintenance, documentation, user satisfaction, commissioning and tuning.

It can help building owners or managers, HVAC professionals and other users discover how to make significant improvements to HVAC energy efficiency in a commercial office building of any size or grade. It's been designed to be used alongside national programs such as Green Star and NABERS and can be used to identify areas to improve ratings.
