VAULT HVAC AND CLEANING

Owner: Director of Facilities, GM approval on any spec change Standard: pandemic-grade air handling, hospital-grade sanitation, luxury-grade finish. Members should never see a cart, a mop bucket, or a chemical smell.

1. AIR HANDLING DESIGN INTENT

VAULT’s HVAC is designed to accomplish four things at once:

1. Remove airborne pathogens, allergens, and combustion byproducts.
2. Hold precise temperature and humidity per zone.
3. Deliver ventilation rates that keep CO2 low and cognitive performance high.
4. Do all of the above at whisper-quiet operation, under NC 30 in guest zones and under NC 35 on the training floor.

1.1 Zone setpoints

Humidity in pole studios is held toward the top of the range for grip. Recovery deck humidity is held higher for skin comfort post-plunge.

1.2 Filtration and treatment

• MERV 14 pleated filters at the return of every air handler, replaced on a 60 day cadence or on differential pressure alarm, whichever comes first. Preferred spec: AAF Flanders VariCel or Camfil Hi-Flo XLT MERV 14 in matching frames.
• UV-C germicidal lamps installed in every air handler downstream of the coil, sized to deliver a validated kill dose against common respiratory pathogens at design airflow. Bulbs replaced annually or per manufacturer’s lumen depreciation curve. Lamps interlocked to service switches so they cannot be viewed by a technician while energized.
• Bipolar ionization or needlepoint ionization at the supply plenum where the design supports it, targeting neutralization of surface and airborne particulates. System selected must have UL 2998 zero ozone emission certification. No exceptions.
• HEPA units as standalone in the recovery deck locker vestibule and in the medical screening room off the main floor.

1.3 Ventilation rates

• Air changes per hour (ACH) target: minimum 6 ACH total in every guest occupied zone, with minimum 3 ACH of outside air where the building envelope and load permit.
• Training studios operate at 8 ACH total during class and step up to 12 ACH for 6 minutes at end of class as the exhaust purge cycle.
• Sauna and steam room mechanical exhaust runs continuously at design rate. Ambient sauna room exhaust ramps up during peak.
• Cold plunge deck exhaust sized for latent load control, humidity held below 55 percent to prevent musty odor and biofilm growth on ceilings.

1.4 Humidity strategy

• Central humidification via steam injection for winter operation. Steam quality tested annually.
• Central dehumidification integrated with cooling coils and reheat, or dedicated outdoor air system (DOAS) with wheel, per the mechanical design.
• Pole studios have local sensors calibrated quarterly. Reading logged at open, midday, and close. If humidity falls below 35 percent or climbs above 55 percent, members are notified politely and grip aids are offered gratis while the system corrects.

1.5 Commissioning and verification

• Full commissioning at opening by an independent commissioning agent, sealed report on file.
• Recommissioning every 3 years.
• Airflow at every diffuser measured with hood annually.
• Filter differential pressure logged weekly.
• CO2 monitored continuously in every zone, logged to the ops system, alarm on threshold.
• UV-C lamp intensity measured annually with a UV meter.
• Duct interior inspected every 3 years by camera, cleaned per NADCA standard on any finding.

2. WATER SYSTEMS

2.1 Domestic hot water

• Delivered at fixtures at 104 to 108 F for showers, 110 F at sinks with anti-scald mixers.
• Recirculation loop maintains temperature to reduce Legionella risk. Legionella testing quarterly, cultured by an accredited lab.
• Point of use booster where needed for the cafe and laundry.

2.2 Cold plunge

• Filtration: 10 to 20 micron mechanical pre-filter, UV plus ozone treatment, secondary sanitizer (chlorine or bromine per unit spec).
• Chemistry logged 4 times daily: open, midday, evening peak, close.
• Targets: free chlorine 1.0 to 3.0 ppm, pH 7.2 to 7.6, ORP above 650 mV, total alkalinity 80 to 120 ppm, calcium hardness per unit spec.
• Skimmer emptied at every log entry.
• Weekly deep sanitation cycle out of hours: drain 25 percent, refill, shock treat, run filtration overnight, retest before open.
• Quarterly full drain, chamber sanitation, refill.
• Water quality testing sent to an accredited lab monthly.

2.3 Steam room

• Steam generator descaled per manufacturer, quarterly minimum.
• Aromatherapy injection uses medical grade oils only, from the approved spa oil vendor on 04_VENDOR_ROSTER.md. No member-supplied oils.
