In September 2015, the Department of Industry, Innovation and Science (DIIS) engaged Australian Survey Research (ASR) to conduct a survey testing several elements of a new form of energy labelling referred to as a Zoned Energy Rating Label (ZERL). The rating labels were designed for products where performance, energy efficiency and usage patterns are impacted by the location in which they are installed.
This report outlines the development of a zoned map for Solar Water Heaters (SWH) and documents the methodology used.
The map characterises the performance of SWHs in differing regions of Australia and New Zealand. With the intention to display the map on a ZERL it will enable comparisons across and within all residential water heater categories.
The E3 Committee is currently investigating introducing a new type of ERL for appliances for which performance, energy efficiency and/or usage patterns are dependent on the location they are installed. These appliances include air conditioners, space heaters and water heaters.
A selection of ‘zoned energy rating labels’ have been designed, splitting Australia and New Zealand into three climate zones – mixed, hot/humid and cold. Following several rounds of qualitative and quantitative testing of consumers and industry, a draft design for the label was finalised.
