Mixed-Use Buildings

Mixed-use buildings stack different occupancies on top of each other: apartments or condos above, retail and restaurants at street level, and parking below. Each has its own mechanical needs, and the systems have to be separated, metered and coordinated in tight ceiling spaces.

How is a mixed-use building's mechanical system different?

A mixed-use building stacks different businesses and homes under one roof, often stores or restaurants below and apartments or offices above. Each use needs different systems, and they have to be kept separate.

Different systems per use

Apartments, retail, restaurants and offices often get separate HVAC types, meters and controls.

Restaurant infrastructure

Grease waste, kitchen exhaust and gas piping must route through floors above without affecting residents.

Separation and sound

Fire-rated separations and noise control matter where homes sit over commercial space.

Tenant fit-outs

Base building systems are built first and finished later as tenants move in.

Mechanical scopes

Residential HVAC

Split systems, VRF or water-source heat pumps for units, plus dwelling-unit ventilation and corridor makeup air.

Retail & restaurant shells

Rooftop units or capped connections for tenants, grease waste interceptors, gas service and kitchen exhaust shafts.

Plumbing

Domestic water with submetering, water heating plants, and sanitary and storm systems that transfer between occupancies.

Parking ventilation

Garage exhaust with CO and NO2 sensing.
