Most manufacturing plants have energy overheads, that is, energy using equipment which is left on even if the plant is not producing any product. This can be addressed:
- with good control engineering, by installing timers to turn machinery and equipment off or to idle setting when not required (including equipment such as air compressors, air conditioners and lighting)
- by fixing or replacing temperamental equipment so that all equipment can be turned off and on regularly without the risk that it won’t restart
- identify and insulate equipment that continues to lose or gain heat when useful services are not being delivered
