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
radiator
Mechanical
Heating systems:
Hot water
Radiant Flooring
