Summary

This paper was prepared in December 2005 by Energy Efficient Strategies, for the Equipment Energy Efficiency Committee (EEEC).

It sets out a new proposed energy labelling star rating algorithm (equation) for introduction in Australia and New Zealand during 2007. The paper also flags the key issues for government and industry which need to be considered in the transition process to the new energy label and star ratings.

It also sets out plans by the Equipment Energy Efficiency Committee to introduce Energy Star as the primary high efficiency endorsement label for refrigerators in Australia and New Zealand. Draft eligibility criteria for the Energy Star for refrigerators and freezers are also proposed.

This paper documents the following issues and proposals:

Provides background on energy trends for refrigerators and freezers in Australia since labelling began in 1986.
Documents the star rating equations introduced in 2000 and provides a rationale as to why these equations need to be revised and upgraded in the light of MEPS 2005.
Lists issues that need to be considered in the development of a new star rating algorithm.
Details a new star rating equation for refrigerators and freezers that is proposed for implementation in 2007.
Presents a detailed discussion on the issue of adaptive defrost and whether or not a credit for this feature should be included in the star rating algorithm - detailed submissions are sought on this issue before a final decision can be made.
Provides an overview of the current endorsement labelling system (TESAW) and details the proposed transition to Energy Star as the primary endorsement system in Australia and New Zealand. Initial Energy Star criteria for refrigerators and freezers are also documented.
Documents a range of labelling, implementation and transition issues that are still to be finalised prior to the introduction of the new star rating label and the transition from TESAW to Energy Star in 2007.

This discussion paper is the first step in the process of introducing a new star rating algorithm for refrigerators and freezers in 2007.
