4E Evaluation Guidebook

The 4E Evaluation Guidebook is intended to assist impact evaluations of equipment energy efficiency standards and labelling (EES&L) programmes. It explains the methodologies that are proven to deliver robust and credible evaluations within five key steps.

Emerging Battery Technologies

This research study examines new battery technologies suited to powering small devices such as IoT, actuators and sensors, and portable devices such as mobile phones and laptops.

Round Robin of Converter Losses

This report summarises the results of the IEA 4E EMSA international Round Robin testing programme for converter losses, implemented in cooperation with IEC SC22G/WG18.

Smart Lighting – New Features Impacting Energy Consumption

Smart lamps and luminaires are common in today’s lighting market. Smart lighting provides an opportunity for the consumer to benefit from wireless control of lighting products, e.g. by dimming, colour tuning and scheduling. These functions can provide energy saving but they also require energy consumption to supply standby power and gateways.

Guide to Energy Management Protocols

This report is a guide to ‘application layer’ communications protocols used for energy management, such as those used to facilitate intelligent efficiency and demand flexibility.

Mobile Device Efficiency

This report analyses the energy use of mobile devices, compares policies and identifies policy gaps.

Interoperability

The objective of this study is to gain a better understanding on the issue of (a lack of) device interoperability and the resultant impact of this on Intelligent Efficiency and Demand Flexibility

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.

Classification of digitalisation technologies for electric motor driven systems

This report by EMSA provides a classification of different digitalisation technologies applied for motor systems. The following technologies are analysed: sensors, Internet of Things, intelligent control, data analytics, real-time monitoring, artificial intelligence, digital twins, cloud based services, augmented reality, additive manufacturing, robotics, drones.

LED Product Lifetime Testing Report

A new report by the IEA 4E Solid State Lighting Annex provides a look across the body of literature on lifetime definitions for LEDs and LED products. The reports looks at failure mechanisms, accelerated life tests and test methods for estimating lifetime, and provides some recommendations. There is currently no agreement as to which test […]
