4E Projects

4E Projects are highly focused research activities that tend to have a shorter-term focus than Annexes and are usually exploratory in nature. These are managed by the 4E ExCo and are additional to the work undertaken by Annexes.

To gain approval, 4E Projects should:

  • Demonstrate well-defined objectives and realistic deliverables, which are best achieved through international collaboration.
  • Lead to significant improvements in energy efficiency or address one or more current barriers.
  • Not duplicate activities undertaken by another organisation or that could be better led by others.

4E has undertaken a wide range of projects. Follow the links on this page to find related details and publications.

Air Conditioners

With the uptake of air conditioning growing globally, this project seeks to ensure that the performance testing of the popular inverter-type units (heat pumps) is sufficiently robust to support national regulations for energy efficiency

Energy-using Systems

Systems represent a significant potential for new energy savings, and their regulation could provide flexibility in ways that industry can meet policy requirements

The Motor Driven Unit policy guidelines

The options for harmonising technical standards and regulations for pumps, fans and compressors which globally consume an estimated at 6,560 TWh of electricity (larger than the total electricity consumption of China)

IEA Energy Efficiency Reports

Since 2015, 4E has provided input to successive editions of the IEA’s flagship report on energy efficiency, which quantifies the latest trends, tracks global progress, and examines key drivers and market issues

Policy Driven Innovation (PDI)

This research examined the options global government cooperation to deliver regulatory solutions suitable for use and adaption within the legal bounds of national schemes to push global innovation and technology changes for appliances and equipment

Smart Metering Infrastructure

How significant is the self-energy consumption of smart metering infrastructure, and what impact does different technologies and architecture have?
