The National Australian Built Environment Rating System (NABERS), is a government initiative to measure and compare the environmental performance of Australian buildings. There are NABERS rating tools for commercial office buildings to measure energy efficiency, water efficiency, waste efficiency and indoor environment quality. There are also energy and water rating tools for hotels and shopping centres.

To obtain a rating, twelve months of consumption data for the building (such as utility bills) is collected by Accredited Assessors along with data about a number of other aspects of the building such as it's size, hours of occupation, climate location and density of occupation. Data requirements are set out in a document called 'The Rules for Collecting and Using Data'. This data is then input into the NABERS calculator which statistically adjusts for these factors so that the building can have its consumption fairly benchmarked against it's peers. The result of this calculation is a star rating on a scale of one to six, with one being very poor performance and six being market leading performance.

This system is different to other building rating systems, such as the Green Star or LEED rating systems, both of which are points based.
