How Is MEP Engineered for Convention Center Commercial Kitchens?

By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15

Convention center kitchen MEP centers on Type I hoods with interlocked tempered makeup air, banquet-peak gas and power, grease interceptors, surge-capable hot water — plus integrated hood fire suppression and capture testing.

Hoods, exhaust, and makeup air

I start from the cooking equipment schedule: every grease-producing appliance gets a Type I hood positioned and sized for capture, with exhaust rates matched to the equipment duty. Hood groups are zoned so a dark line does not exhaust like a working one, and each group is interlocked with dedicated tempered makeup air — no exhaust without its replacement air. Grease ductwork is built to grease-duct standards with cleanouts, routed to minimize horizontal runs, and the discharge is located away from air intakes and the banquet hall's outdoor areas. The kitchen's air balance is verified in commissioning with all hoods running: near-neutral to the dining room, every time.

Gas, power, water, and fire protection

Gas service is sized for the full equipment lineup at banquet peak with seismic shutoffs and combustion air; electrical covers cooking, refrigeration, dish machines, and small appliances with ground-fault protection where required. Hot water pairs high-recovery heaters with storage for the post-service surge, and drainage runs through grease interceptors on an accessible pumping schedule. Fire protection is designed in: listed hood suppression with automatic fuel shutoffs, integrated with the building fire alarm, plus extinguisher placement matched to the kitchen layout. The hood capture-and-containment test with equipment running is the commissioning milestone that proves the kitchen is safe to operate.

Convention center kitchen MEP checklist

A banquet kitchen MEP design is ready when it clears this checklist. Feeding 5,000 on time, safely, is the standard. • Type I hoods sized to equipment duty with capture-and-containment testing • Dedicated tempered makeup air interlocked with every hood group • Gas and electrical sized for simultaneous full-equipment banquet peak • Grease interceptors on an accessible pumping schedule, separated from sanitary mains • Listed hood fire suppression with fuel shutoffs, integrated to the building fire alarm

What else do project teams ask?

What is a Type I hood and when is it required?

A Type I hood is the grease-rated exhaust hood required over any cooking equipment that produces grease or smoke — fryers, grills, ranges, broilers. It includes grease filters, a listed fire suppression system, and exhaust ductwork built to grease-duct standards with cleanout access. The hood size and exhaust rate follow the equipment's cooking duty: a heavy-duty broiler line needs a bigger hood moving more air than a bank of convection ovens. Type II hoods, for heat and steam without grease, are a different and lighter design — the cooking equipment schedule determines which applies where.

Why does kitchen exhaust need dedicated makeup air?

Because exhaust without makeup air destroys the building's air balance. A banquet kitchen's hoods can exhaust tens of thousands of CFM; without dedicated tempered replacement air, that volume gets pulled from the banquet hall and corridors, driving the kitchen negative — doors slam or will not open, dining-room conditioned air is wasted, and hood capture itself degrades as air rushes past the cooking line. I interlock each hood group with its own tempered makeup air unit so the hood cannot run without its replacement air. The kitchen stays near neutral to the dining room, and the dining room's HVAC survives service.

How is kitchen hot water sized for banquet service?

For the post-service surge. During the banquet the demand is moderate; when 5,000 covers end, the dish pit, pot sinks, and washdown all demand hot water at once. I size high-recovery heaters with storage volume that rides through the cleanup peak and recharges before the next seating, with recirculation keeping hot water at the farthest fixture. The dish machines' own booster heaters are coordinated with the building supply temperatures. A kitchen that runs out of hot water mid-cleanup stops the whole turnaround for the next event.

How is grease kept out of the plumbing system?

With interceptors and separation. All grease-producing fixtures and floor drains in the cooking areas route through a grease interceptor — sized to the kitchen's output and the local code — before joining the sanitary system, and the interceptor is accessible for the regular pumping schedule. The interceptor is never bypassed, and food solids go through strainers and scrap handling rather than the drains. I keep the grease waste path short and maintainable, because a neglected interceptor backs grease into the kitchen during the busiest service of the year.
