In New Zealand's building energy ratings are voluntary while neighboring Australia has had a mandatory building energy ratings system since since 2009.
A 2015 Australian report -- Commercial Building Disclosure -- estimated $44 million in energy savings and $168 million in energy rating system.

According to the report, previous estimates, including a recent report by the Productivity Commission, suggested that buildings were responsible for roughly 5 pct of emissions or less. The new report, however, found buildings could amount to 20 pct of New Zealand's carbon footprint when considering their lifetime "embodied" emissions.
The thinkstep report arrived at the larger figure for the climate emissions of buildings than previous studies using a methodology that allocated emissions to a sector at the point of consumption, rather than production, and because it considers the entire life cycle of buildings, including the extraction of raw materials, material production, the electricity and energy use of the building, and the treatment of construction waste.
