Hospitality & Hotels
In hospitality, MEP failures become online reviews — a fan-coil that hums all night, a lukewarm shower at 7 AM, a smoky kitchen line, a clammy pool deck. We deliver construction-ready MEP that performs when the property is sold out, not just on a design-day spreadsheet.
Guest Comfort Is an Engineering Spec.
A hotel is a dozen occupancies under one roof — guestrooms, commercial kitchen, ballroom, laundry, pool, back-of-house — each with its own air, water, and power profile, all sharing risers and a peak that hits at the worst time. We hold guestroom noise criteria, size hot water for the morning shower surge under ASHRAE 188 Legionella limits, and cascade pressure so kitchen, trash, and pool air never reach a corridor — all behind the seal of the licensed engineer of record on your project.
Guestroom & Common-Area HVAC
Quiet rooms guests sleep through, and common areas that hold comfort across wildly different occupancies.
- Guestroom PTAC, vertical fan-coil, or VRF selection driven by noise criteria — NC-35 typical, NC-30 for luxury — with placement and attenuation to hold it
- Corridor make-up air pressurizing guestroom floors so doors seal and odors don't migrate room to room
- DOAS with energy recovery delivering ventilation per ASHRAE 62.1 / IMC occupancy rates
- Ballroom and banquet zoning for the swing from empty to packed, with CO2 demand-control ventilation
- VRF heat-recovery and central-plant options weighed against first cost, maintenance, and brand standard
- Vibration isolation and acoustic detailing keeping equipment noise out of sleeping areas
Commercial Kitchen & Laundry
The back-of-house systems that, balanced wrong, smoke up a dining room or pull doors shut.
- Type I and Type II hood selection and grease-duct routing per IMC and NFPA 96
- Make-up air balanced to the hoods so the kitchen holds neutral-to-negative and the dining room doesn't whistle
- Fuel-gas piping and regulators reconciled line-by-line against the kitchen equipment package per IFGC / NFPA 54
- Commercial laundry exhaust, make-up air, and dryer venting sized to the equipment
- Hood fire-suppression interlocks and shunt-trip coordination with the suppression vendor
- Grease interceptor sizing and indirect-waste routing to the local sewer authority
Domestic Hot Water & Plumbing
Hot water that survives the 7 AM shower surge without becoming a Legionella liability.
- Peak-demand DHW plant sized to the morning surge — storage, recovery, and balanced recirculation so the farthest room isn't the coldest shower
- ASHRAE 188 water-management strategy: hot storage near 140°F with ASSE 1070 thermostatic mixing valves limiting fixture delivery for scald protection
- Recirculation loops held above the Legionella growth band end to end, with the tradeoff against ASHRAE 90.1 energy limits documented
- Booster heating for dish lines and laundry
- Backflow prevention, floor drains, and indirect waste per IPC / UPC
- Storm and sanitary coordination through stacked guestroom and podium risers
Pool, Spa & Wellness
Natatorium and spa air that protects the guests, the structure, and the finishes.
- Dedicated pool dehumidification units sized for evaporative load, holding 4–6 air changes per hour
- Negative-pressure natatorium design so chloramine-laden air never reaches guest corridors
- Corrosion-resistant ductwork and materials, with supply sweeping the deck and glazing to prevent condensation
- Pool, spa, and water-feature equipment power and controls coordination
- Spa, sauna, and locker-room exhaust and humidity control
- Outdoor-air rates and surface ventilation per ASHRAE 62.1 for indoor aquatics
Electrical, Life Safety & Brand Standards
Power across mixed occupancies, code-compliant egress, and the franchise prototype reconciled to local code.
- Service and distribution sized for guestroom load diversity plus kitchen, laundry, and amenity demand
- Lighting and dimming/scene control across lobby, guestroom, and amenity, designed to brand and IES levels
- Fire alarm, egress, and life safety across assembly and residential occupancies per NFPA 101
- Full NFPA 13 sprinkler coordination — hotels are fully sprinklered, not NFPA 13R
- Emergency and standby power for egress, elevators, and life-safety systems
- Brand prototype standards (franchise PIPs) reconciled with the adopted local code before submittal
Quick answers about how we deliver design support for this sector.
Yes. We design to the flag's prototype MEP standards — Marriott, Hilton, Hyatt, IHG, and the rest each publish their own — and reconcile them against the adopted local code before submittal. Where a brand spec and the AHJ conflict, we flag it early and resolve it so the set satisfies both the flag and the jurisdiction. On conversions and PIP renovations we work from the existing building back to the new standard.
We size the domestic hot-water plant — storage, recovery, and recirculation — to the real morning surge, not a design-day average, so the building holds temperature when it's full. Then we layer the ASHRAE 188 water-management approach: hot storage around 140°F with ASSE 1070 thermostatic mixing valves limiting fixture delivery for scald protection, and recirculation loops kept above the Legionella growth band end to end. That deliberately runs against ASHRAE 90.1's energy limits, so we document the basis for the licensed engineer of record on your project.
Yes — Type I and Type II hoods, grease-duct routing, and fire-suppression interlocks per the IMC and NFPA 96, with fuel gas reconciled to the equipment package under IFGC / NFPA 54. The make-up air is balanced to the hoods so the kitchen stays slightly negative and smoke and odor never reach the dining room or guest corridors. We coordinate the whole package with your kitchen consultant.
By engineering the pressure cascade across the building. Guestroom corridors are pressurized positive; kitchens, laundry, pool, and trash rooms are held negative with dedicated exhaust. We map those relationships at design rather than balancing them into compliance later, so air always moves away from where guests are.
Yes, and it's a space that punishes a generic approach. We size dedicated dehumidification for the evaporative load, hold the room negative so chloramine air can't migrate, sweep supply air across the glazing and deck to stop condensation, and specify corrosion-resistant materials throughout — designed to ASHRAE guidance for indoor aquatic facilities so the structure and finishes last.
