Certain types of liquid chilling packages (chillers) are currently required to meet minimum energy performance standards (MEPS).

The current approach to registering chillers is not suited to the bespoke nature of these products. Not many chillers are made in New Zealand and Australia, some of those that are, are exported overseas. E3 is proposing to align internationally, with EU and North American requirements.

  • In Europe, 1 Jan 2018 saw the introduction of cooling MEPS. Heating MEPS 2016, Tier 2 in Sept 2017.
  • Proposing to accept both the new EU Eurovent standards and the established North American AHRI/591.

Current regulations only cover larger chillers above 350 kW. E3 is proposing to expand the scope to include smaller chillers, including reverse cycle chillers.


A proposal to update the MEPS on chillers was included in the Consultation Regulation Impact Statement: Air Conditioners and Chillers and Air Conditioners and Chillers – Updated Policy Proposals, both published in 2016. Stakeholders raised a number of issues that have required further investigation. Since then the E3 programme has been working with stakeholders to ensure the final proposal is suitable for regulation.

A consultation paper to resolve some of the issues with chillers was released in June with public consultation meetings in July in Australia and New Zealand.

Following consultation on the Chillers: updated policy positions paper, E3 will address feedback received and release a short paper which will indicate the direction that will be put to Ministers.

EECA will keep stakeholders updated on the process and it progresses, to ensure you are included email to express your interest in the chillers proposal.

The consultation period closed on 3 August 2018.
