Duty cycling in the context of equipment usage emphasizes the importance of managing the operation of equipment to optimize energy efficiency while ensuring functionality during occupied hours. The concept involves strategically turning off equipment during intervals when it may not be needed, even within periods of usage, to reduce energy consumption without impacting comfort or productivity.

By turning off equipment for predetermined durations during occupied hours, buildings can effectively save energy and reduce operational costs. This practice allows for the balancing of equipment efficiency with user comfort, ensuring that systems are not functioning in full capacity when the building's demand does not require it. It addresses the need for conservation by avoiding unnecessary energy use during moments when equipment has lower demand or when building occupants might not need all the systems to be fully operational.

This approach contrasts with continuous operation, which may maximize output but often leads to unnecessary energy consumption. It also differs from simply turning off equipment during unoccupied hours, as that option does not take into account the strategic timing during occupied periods. Lastly, the idea of reducing wear through constant usage is generally not aligned with energy-efficient practices, as it overlooks the benefits of cycling equipment in an effective manner.
