Demand-Controlled Kitchen Ventilation
Demand-controlled kitchen ventilation (DCKV) automatically reduces kitchen hood and make-up air fan speed during times of low activity or demand. Energy savings are achieved as a result of reduced fan power and reduced make-up air heating requirements.
Requirements and Specifications: This measure applies to retrofits and new construction.
- For existing applications, the ventilation system has a constant-speed exhaust fan.
- For new construction applications, there are no pre-conditions where not otherwise required by code.
Installed demand-controlled kitchen ventilation equipment that:
- Controls the primary ventilation and make-up air units in the zone
- Utilizes one or more control sensors to modify the fan speeds.
