Energy Management Glossary
Concise explanations of terms from energy management, ISO 50001, carbon footprint and 3D scanning, with examples from manufacturing.
Energy management uses a number of abbreviations and terms that are easily confused. This glossary explains the most important ones simply and with an example from a production plant. The explanations are based on the ISO 50001:2018 standard and related standards, and on Czech Act No. 406/2000 Coll. on Energy Management.
