Progressing Energy Efficiency Policies for Systems

Systems are described as the next frontier for energy efficiency policy, offering the potential to unlock huge energy savings in equipment-based energy-using systems.
In this summary we highlight some of the key findings from 4E’s investigations over several years.

Controls Validation Method for Variable Speed Air Conditioners and Heat Pumps

This controls validation method aims to provide a uniform method of test which will validate native control operation and performance criteria for residential air conditioners and heat pumps with variable speed compressors. This method is intended to be used as a confirmation against regulatory tests in which modulating component(s) are overridden.

AC/HP Test Methods 2.0: Phase 2 Findings Summary

This research aims to develop an internationally applicable load-based test method for variable capacity ACs and HPs and has 4 Phases. This report discusses the findings of Phase 2 (Investigative Testing of Key Issues), as well as the research team’s recommendations for Phase 3 work.

Domestic Air Conditioner Test Standards and Harmonization

This report is a comparative review of test procedures and efficiency metrics for room air conditioners across six countries, as well as the ISO standard. The findings of this report are intended to inform the efforts of policy makers to evaluate where greater consistency between test methods and metrics may be beneficial.

4E EMSA Policy Guidelines for Motor Driven Units – Part 1 Summary

This document summarises the first part of an investigation into policy options for harmonising standards and regulations for Motor Driven Units (MDUs), focusing on pumps, fans and compressors. Part 1 describes existing standards and regulations for MDUs in economies that account for 85% of global motor system electricity use
