Household Refrigerators – Energy Modelling Methodology for MEPS 2021 Compliance


Household Refrigerators – Energy Modelling Methodology for MEPS 2021 Compliance

In November 2017, Energy Ministers agreed to the Decision Regulation Impact Statement (RIS) – Household Refrigerators and Freezers . Accordingly, implementation is underway to introduce tighter minimum energy performance standards (MEPS) and adopt the international test standard for household refrigerators and freezers. The GEMS Regulator and the New Zealand Regulator are undertaking an assessment of currently registered household refrigerating appliances, using existing registration data, to determine whether appliances will be compliant with new MEPS levels that are anticipated to commence on 1 January 2021.

This approach will reduce both regulatory and administrative burdens during the two‑year transition period between when the replacement Greenhouse and Energy Minimum Standards (Household Refrigerating Appliances) Determination is published (expected late 2018) and when it comes into force.

Products will be assessed to comply with MEPS 2021 levels if their assumed energy consumption under the International Electrotechnical Commission (IEC) 62552-3:2015 test standard is less than 90 per cent of the energy consumption allowed according to the product’s MEPS cut-off level.

The technical paper Household Refrigerators: Energy Modelling Methodology for MEPS 2021 Compliance sets out the approach used to convert energy consumption measured under the current AS/NZS 4474.1:2007 test standard to the likely energy consumption under the IEC 62552 3:2015 test standard.

Registrants with existing affected registrations will soon be contacted with details concerning their affected models and options they may have to demonstrate compliance with MEPS 2021 levels.
