MEP design
Mechanical, 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
(heating & cooling)
Mechanical
Heating systems:
Forced air
gas furnace w/flue
Fan + coil
Mechanical
Heating systems:
Forced air
Heat pump
Why heat pumps
don’t work in cold
climates
Mechanical
Ducting:
Supply & Return
Register types & locations
Size & noise
Rectangular vs Spiral
Fresh air intake
Exhaust (equipment rooms, restrooms)
Mechanical
Equipment location
(100’ refrigerant line, insulated)
