Air-Handling Units & Terminal Air Distribution installations at King Abdulaziz International Airport (JED)

Once chilled water is produced, it is the air side that delivers comfort to passengers. This sub-category covers built-up and modular air-handling units, packaged rooftop units, fan-coil units, ducted split systems, and VRF/VRV heat-recovery systems for offices, lounges and support buildings, plus displacement ventilation for high, glass-fronted hold rooms. AHU selection in high-heat climates prioritises desert-grade pre-filtration, high external static for long terminal duct runs, condensate management at 85% apron humidity, and AHRI 430 certification. VRF/VRV systems serve the back-of-house and modular expansions where central plant is uneconomic. Buyers compare casing thermal-bridging, fan-array vs single-fan designs, and energy-recovery wheels for fresh-air make-up.

Jeddah is the gateway to Makkah — and few airports carry such spiritual and logistical weight in a single footprint. Its Hajj Terminal, a Skidmore Owings & Merrill marvel of tented fibreglass, has moved pilgrims for four decades while the new Terminal 1 by HOK now handles Saudia's widebody flows. 2024 traffic climbed to 49.1 million as the Kingdom chases a goal of 150 million pilgrims and tourists a year by 2030.
