EMSA conducted an international round robin testing programme and developed a guide to the measurement of packaged air compressor specific energy and isentropic efficiency based on ISO 1217:2009. An Excel calculation tool has been developed to perform the stepwise calculation of the isentropic efficiency based on test results as specified in ISO1217.
EMSA released a Policy Brief, assessing the importance of electric motor systems in the global energy system. In 2023, electric motor systems were responsible for 53% of global electricity consumption. Their share in electricity consumption varies widely across sectors: 72% in industry, 36% in buildings, 87% in agriculture and 86% in the transportation sector.
The next EEMODS takes place on 19 – 21 May 2026 in Berlin. Abstracts can be submitted until 31 January 2026.
The Government of Australia withdraws from EMSA, following which EMSA has 9 members.
In a new report, commissioned by the 4E TCP EDNA Platform and the Users TCP, the Austrian Institute of Technology conclude that policy and behavioural measures are as important as technical ones.
EMSA just released a new report with the results of a test series of industrial Silicon Carbide Variable Speed Drives, revealing clear efficiency advantages, but also the need for further research on challenges.
EMSA is happy to welcome its new member country Canada, represented by Natural Resources Canada.
Today, the SSL Annex has published the Nucleus Laboratory Comparison report – Part 2 of the 2023 Interlaboratory Comparison (IC 2023). IC 2023 is investigating the degree of agreement in the measurements of temporal light modulation (TLM) quantities, in particular, short-term flicker indicator (PstLM), and stroboscopic effect visibility measure (SVM).
As part of a Swiss research project, a motor system using silicon carbide (SiC) MOSFET-based Variable Speed Drive was evaluated against a conventional system with insulated-gate bipolar transistor (IGBT) technology. Energy loss measurements from both systems were used to estimate the potential savings if all speed-controlled pump drive systems worldwide were converted to SiC technology. The results point to a global annual savings potential of 17 – 25 TWh.
The latest policy brief from PECTA, ‘Circular Economy – Compatible Power Electronics and New Application Areas’ has been published and is available for download here.
A new report, commissioned by the 4E TCP, explores opportunities to improve the energy efficiency of systems using modelling and monitoring in regulations. The learnings found in the report were applied to an electric motor related case study system: compressed air systems.
Today, at the CIE Midterm Meeting in Vienna, Austria, Dr. Yoshi Ohno, an Expert of the SSLC Platform has presented the first results of the Interlaboratory Comparison (IC 2023) of the measurement of temporal light modulation (TLM) of solid-state lighting (SSL) products.
The IEA’s Digital Demand-Driven Electricity Networks (3DEN) Initiative, the IEA 4E TCP Efficient, Demand Flexible Networked Appliances (EDNA) and the Super-Efficient Equipment and Appliance deployment (SEAD) initiative are co-organising a webinar focused on the electricity use of data centres and the role of energy consumption data in enabling effective policy and planning.
U4E released its updated Motor Policy Guide and Model Regulations to support policy makers in developing countries and emerging economies in transitioning to energy-efficient motor systems.
The adoption of Wide Bandgap (WBG) semiconductors in industrial Variable Speed Drives (VSDs) presents multiple advantages, including improved efficiency, reduced cooling requirements and smaller form factors. Despite their numerous advantages, the adoption of WBG industrial VSDs faces several challenges.
Today, the SSLC Platform published a new paper on Temporal Light Artifacts (TLAs) which are undesired visual perceptual effects, caused by Temporal Light Modulations (TLMs)
New EDNA report examines the ability of ‘flexibility platforms’ to unlock demand flexibility from appliances in the household and commercial sectors. Download here.
4E TCP has developed a new test procedure to better reflect the benefits of dynamic load control, beyond a test which locks the fans and compressors at a fixed speed. This report provides the results of a round-robin testing across multiple international laboratories to evaluate the reproducibility and representativeness of this new Test Method for AC/HP products.
EDNA has published 2 new reports on data centres: Data Centre Energy Efficiency Labels and Public Data on Data Centre Energy Use.
This report focusses on cybersecurity threats in relation to demand flexible networked appliances. It investigates current efforts to address these, and summarises the issues that policy makers should be aware of in relation to minimising cybersecurity risks.
