MEP designMechanical, Electrical, Plumbing

Often separate consultants

Can be separate even within a single firm

Often performed on a design-build basis (no drawings)

Mechanical

Basic system function:

Temperature conditioner (heat or cool)

Heat exchanger (fan+coil, radiator)

Package units

Split systems (condenser/furnace + fan coil unit)

Piped water (radiator/fan coil + chiller/boiler)

Mechanical

Cooling systems:

Forced air only

Ventilation

“Air Conditioning” (Refrigeration) – how does it work? Where does the heat go?

Mechanical

Heating systems:

Hot water

gas boiler w/flue

electric boiler
