Greenhouse and Energy Minimum Standards (Air Conditioners up to 65kW) Determination 2019

Last updated: 22 August 2019

The Greenhouse and Energy Minimum Standards (Air Conditioners up to 65kW) Determination 2019 (the Determination) updates energy labelling and product performance testing requirements for air conditioners up to 65 kilowatts rated capacity.

This Determination omes into force on 1 April 2020, revoking and replacing the Greenhouse and Energy Minimum Standards (Air Conditioners and Heat Pumps) Determination 2013 (revoked Determination).

The Determination introduces a Seasonal Energy Efficiency Rating (SEER) standard for energy efficiency rating purposes and a re-designed Energy Rating Label. For the vast majority of air conditioners covered by the Determination, the Minimum Energy Performance Standards (MEPS) levels will not change. MEPS levels are also referred to in the Determination as greenhouse and energy minimum standards (GEMS) level requirements.

This Determination does not cover the following:

(a)  close control air conditioners;

(b)  liquid-chilling packages;

(c)  evaporative coolers or any other cooling systems that are not of the vapour compression type;

(d)  ground-water air conditioners or ground-loop air conditioners;

(e)  spot coolers;

(f)  dehumidifiers;

(g)  air conditioners powered by mains electricity specifically designed and sold only for installation in end-use mobile applications, such as caravans, mobile homes, camper vans, boats and rail cars;

(h)  air conditioners powered by mains electricity specifically designed and sold only for installation in specialised high temperature industrial applications, such as crane cabins used over blast furnaces;

(i)  air conditioners that do not condition air sourced from within the conditioned space, but instead condition air sourced from outside the conditioned space, and deliver that air to the conditioned space.
