How Is Hangar Office and Lounge MEP Designed for Comfort?

The engineer sizes the office HVAC from office loads — people, lighting, equipment, envelope — with no credit taken from the bay next door, and zones it for the way the space is actually used: perimeter offices with solar exposure on their own zones, interior open areas together, conference rooms with occupancy sensors that boost ventilation when the room fills. Equipment is selected for quiet operation with published sound ratings, and the duct design keeps velocities low with silencers at the office boundary. Controls run occupancy schedules with optimal start, setback for unoccupied hours, and demand-controlled ventilation in the denser spaces. The bay's radiant heaters, destratification fans, and door-cycle logic never touch the office system — the two are separate plants or at minimum separate, independently controlled zones.

The office-to-bay separation is drawn as a rated assembly and detailed like one: the fire rating the code requires for the occupancy separation, plus the sound rating the use demands, with every penetration accounted for. Ducts crossing the separation get fire dampers where required and silencers or lined offsets for sound; the engineer shows the exact routing because a straight duct shot through the wall is a speaking tube between the spaces. Doors in the separation are rated, gasketed, and self-closing, arranged in vestibule pairs where the budget allows. Structure-borne noise gets attention too — bay equipment on the shared wall or slab is vibration-isolated, and the engineer verifies that a compressor or door operator bolted to the common structure will not telegraph into the quiet offices. The result is verified against the noise criteria set during design, not assumed.

Use this checklist before the office design is finalized: • Office HVAC fully independent of the bay: own equipment, zones, schedules, and controls • Zones following use and exposure: perimeter offices, open areas, conference, lounge each controlled • Quiet equipment selected with published sound ratings; low-velocity ductwork with silencers at the boundary • Fire-rated and acoustically rated separation from the bay, with every penetration detailed and sealed • Vestibule or airlock entries between office and bay where practical • Restrooms, lockers, showers, and break room sized per code for crew peaks with adequate hot water • Office-grade lighting with occupancy and daylight controls; power on the office distribution • Access control, cameras, and communications on conditioned office power, independent of bay shutdowns
