Commercial Kitchen Demand Ventilation Exhaust During Unoccupied Hours - Can it be shut off?
(OP)
Hi,
I work at a University and have encountered an issue with the internal Fire Safety group regarding off hours kitchen exhaust. They are referring to NFPA96 8.2.1.1 "The air velocity through any duct shall be not less than 152.4 m/min (500 ft/min)" and stating that the hoods must run 24/7 due to this. This project focus' on energy savings so turning off exhaust fans and make up air is critical. Is there a clarification to this code that better explains when the min. 500 ft/min velocity is applicable?
Thanks,
Kyle

if they think this way, you can answer them by the following:
"this room has an occupation load of 10 people, they must stay in this room for 24/7, otherwise, the room will collapse"
