Technology Collaboration Programme on Energy Efficient End-use Equipment (4E)

The IEA 4E 2018 Annual Report makes for interesting reading. It provides, amongst others, policy guidelines for motor-driven units such as fans, pumps and compressors. Within two pages, these guidelines summarise the activities and documents developed by the 4E Electric Motor System Annex (EMSA), which contains most useful information for manufacturers integrating electric motor systems. An upcoming activity will investigate the technological developments in the air conditioning industry, updating earlier reports from 2010-2011.
