Chiller regulation
Chillers produce chilled water that is used by space cooling equipment. Minimum Energy Performance Standards (MEPS) for chillers greater than 350kW capacity were introduced in 2009.
Decision Regulation Impact Statement on the energy efficiency of chillers
While Australia and New Zealand work to harmonise regulatory arrangements, the two countries follow different policy approval and implementation processes.
In 2024 the Australian Energy and Climate Change Ministerial Council agreed to the Decision Regulation Impact Statement (DRIS) proposing an increase in MEPS and expanded scope to include chillers from 100kW capacity. However, in New Zealand the government is still yet to consider the proposed changes.
