This Policy Brief summarises the key findings of the 4E EDNA report: Data Centre Energy Efficiency Labels, which explores the characteristics and effectiveness of existing data centre energy efficiency labels and suggests features for a worldwide applicable labelling scheme.
Interlaboratory Comparison for Temporal Light Modulation Measurement
The 4E SSLC Platform has conducted an Interlaboratory Comparison (IC 2023) for the measurement of temporal light modulation (TLM) of solid-state lighting (SSL) products. Designed to meet proficiency testing requirements, IC 2023 compared measured TLM quantities of short-term flicker indicator (PstLM) and stroboscopic effect visibility measure (SVM, MVS), as well as three other TLM quantities, of four comparison LED lamp artefacts.
Understanding LED performance: Evidence-based approaches to supporting stakeholders of energy-efficient lighting programmes
The SSL Annex takes an evidence-based approach to evaluating LED product performance. Using comprehensive market data from product registries and other sources, the Annex developed recommendations on product performance and research into test methods that reduce the time and cost burden for government, industry and consumers. This paper highlights several activities that exemplify this evidence-based […]
Policy Brief #5 – Coordination between IEC and ISO standards for efficient electric motor driven systems
This policy brief explains the significance of an ISO (International Organisation for Standardization) / IEC (International Electrotechnical Commission) Joint Advisory Group (JAG 22) established in October 2021.
Policy Guidelines for Motor Driven Units, Part 2 – Chinese
This report, available in Chinese, proposes policy options for the international alignment of technical standards and minimum energy performance standards for pumps, fans and compressors.
Policy Guidelines for Motor Driven Units, Part 1 – Chinese
This report, available in Chinese, describes existing standards and regulations for pumps, fans and compressors.
Measurement of temporal light modulation: improving calculation methods for stroboscopic effect visibility measure
The SSL Annex is conducting an Interlaboratory Comparison (IC 2022) on the measurement of temporal light modulation (TLM) from SSL products. In this context, uncertainty associated with SVM calculations must be minimised and remain consistent across a range of waveform measurement parameters (e.g., sampling frequency, duration) used in different systems. This presentation discusses two methods […]
Mobile Device Efficiency
This report analyses the energy use of mobile devices, compares policies and identifies policy gaps.
Interlaboratory Comparison for Goniophotometers (IC 2017)
The final report from the IEA 4E Solid State Lighting Annex’s 2017 Interlaboratory comparison (IC 2017). This comparison had 36 participating laboratories from 19 countries with a total of 42 goniophotometric instruments, the largest interlaboratory comparison of such equipment ever undertaken. This comparison investigated the level of agreement in measurements of SSL products by various […]
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.
AC/HP Test Methods 2.0 – Phase 1 Findings Summary
Air conditioner (AC) / Heat Pumps (HP) Test Methods Project 2.0 – Phase 1 Findings Summary.
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.
