The accurate and repeatable testing of products is a basic requirement for energy efficiency programmes and therefore improving tests for variable capacity air conditioners & heat pumps is important. It is particularly timely given the growth in these types of products. 4E is examining potential changes to relevant test procedures culminating in a round robin within 4E countries which will be completed at the end of 2022.

As part of an ongoing investigation, 4E launched a new project in 2021 to better understand the real and current barriers to regulatory policies for systems in 4E jurisdictions. Based on three case studies, the project will focus on Australia, Canada, the EU and Japan.
Additionally, the project will quantify the total savings potential from the implementation of policies for energy-using systems.

This global assessment of the benefits of standards and labelling programmes is the result of collaborative research between 4E and the IEA. Published in 2021 during the lead-in to COP26 it supports the case for increased investment in these programmes to deliver on international climate commitments.
