What is the focus of duty cycling related to equipment usage?

  1. Continuous operation to maximize output

  2. Turning off equipment during unoccupied hours

  3. Turn off equipment for set times during occupied hours

  4. Reducing wear by constant usage

The correct answer is: Turn off equipment for set times during occupied hours

Duty cycling involves strategically turning equipment off for set periods to optimize energy use and reduce operational costs, particularly during hours when the space is occupied. By intermittently shutting down equipment, energy consumption decreases, while still maintaining a comfortable environment for occupants. This approach is beneficial in managing energy expenditures, particularly in commercial or industrial settings where equipment runs continuously. It allows facilities to avoid the inefficient use of energy and can lead to better equipment lifespan by preventing overheating or excessive wear and tear from constant operation. The emphasis of duty cycling is distinctly linked to balancing comfort and efficient energy use, as opposed to continuous operation or reducing wear through unceasing use. Focusing solely on constant operation or wear reduction fails to align with the principles of energy efficiency that duty cycling promotes.
