The Haj Terminal at King Abdul Aziz International Airport in Jeddah, designed by the Chicago and New York offices of SOM, has been selected to receive the 2010 AIA Twenty-Five Year Award. The AIA Twenty-Five Year Award recognizes an architectural design that has stood the test of time for 25 years. The space serves as a gateway for millions of pilgrims who journey to Makkah each year. The Haj Terminal, completed in 1981, is a tented structure that covers 120 acres and 2.8 million square feet. Its form, site relationship and circulation patterns are drawn entirely from the need to accommodate massive groups from all over the world in a short timeframe. SOM joined this stringent functional requirement with vital cultural and vernacular references. The tent structure that makes up the terminal's roof strongly resembles vernacular Bedouin shelters and Haj pilgrim tents that spring up around Makkah during the Haj season. The terminal is composed of two symmetrical, rectangular sections separated by a landscaped mall. Each terminal section contains 105 tensile fabric tent structures supported by steel pylons and cables. These tents filter out heat and allow in light, creating an open-air gathering place for the multi-ethnic pilgrims. “A marvel of function and design, the structure responds with sensitivity to place, culture and the environment,” wrote AIA Chicago Executive Vice President Zurich Esposito in a nomination letter. The semi-translucent roof system reflects most of the desert sun's heat, but allows light to pass through, keeping temperatures near 80 degrees Fahrenheit, while outside the tent temperatures can be as high as 120 degrees. The terminal is designed to use natural breezes to ventilate and cool the space, and uplighting makes it glow like a lantern in the night sky. For the pilgrims, the experience is meant to honor their journey and sacrifice with a warm and inviting space.
