NABERS – National Australian Built Environment Rating System – is a national initiative managed by the Department of Environment and Climate Change and Water. It is a performance-based rating system measuring the environmental sustainability of building designs and how well operational impacts on the environment are managed. NABERS measures the energy and water consumption of hotels and rates their efficiency on a scale on one to five stars, with one being the lowest and five being best practice. Two and a half stars is the current market average.
