Electric motors and motor systems in industrial and infrastructure applications with pumps, fans and compressors in buildings are responsible for 53% of the world’s total electricity consumption. New and existing technologies offer the potential to reduce the energy demand of motor systems across the global economy by 20% to 30% with short payback periods.
4E’s Electric Motor Systems Platform (EMSA) raises worldwide awareness of the efficiency potential of motor systems and provides guidance and tools to exploit the energy performance of new and existing motor systems worldwide.
From 24 July 2026, new EU ecodesign requirements for industrial fans become applicable under Regulation (EU) 2024/1834. The new regulation raises the minimum energy efficiency requirements for fans driven by motors from 125 W to 500 kW, encouraging the deployment of more efficient fan technologies across industry and buildings.
EMSA published a world map showing mandatory Minimum Energy Performance Standards for pumps, fans and air compressors in effect.
Accurate and reproducible efficiency measurement is a prerequisite for effective energy performance policy. A new EMSA Policy Brief describes the robustness of current methods for determining the isentropic efficiency of small, packaged air compressors.

Accurate and reproducible efficiency measurement is a prerequisite for effective energy performance policy. This new EMSA Policy Brief describes the robustness of current methods for determining the isentropic efficiency of small, packaged air compressors.
This Policy Brief gives an overview of EMSA’s work focus until 2029 and highlights relevant work outcomes to date.
This report summarises the test results of EMSA’s international round robin testing programme, exchanging two commercial, packaged electric motor-driven screw compressors between three laboratories worldwide. It includes a practical guide for measuring specific energy and isentropic efficiency of packaged air compressors in line with ISO 1217:2009 and Amendment 1:2016.
