The outcomes of the project will assist Office of Environment and Heritage evaluate the effectiveness of government programs in driving the uptake of high-efficiency heating, ventilation and air-conditioning (HVAC) products.
As a result of normal barriers of commercial confidentiality, and the fact that the HVAC industry in NSW has almost no engagement with the Energy Savings Scheme, it was not possible to directly collect sales data from a few of the leading suppliers. However, combined with the data that some industry players were willing to supply, high-efficiency sales were able to be deduced and inferred from a range of commercially available and public sector sources.
This study marks the first effort in Australia to calculate the sales weighted energy efficiency of equipment entering a sector of the HVAC market. It is hoped that this starting point can be built upon with the willing participation of industry members, however that will require a continuing effort in market evaluation and engagement of the industry to improve timely access to the underlying data.
