Passenger Terminal Complex at DEN
Denver, Colorado, USA
With a deadline of only three weeks to create the terminal’s conceptual design, Fentress Architects broke the mold of traditional airport architecture by “turning the building upside down.”
Inspired by the majestic Rocky Mountains, Fentress Architects’ design for the Denver International Airport’s Passenger Terminal Complex serves as a memorable expression of civic pride with a strong sense of place. The terminal rises from a solid stone-like base to become a spectacular pavilion, covered by one of the largest tensile membrane structures in the world. Set against a breathtaking view of the Rocky Mountains, this gateway to the West leaves a lasting impression on all visitors to the region.
The design solution was enabled by moving the building’s mechanical infrastructure from the roof to underground, or inverting the typical arrangement. This allowed for the main terminal to be transformed into an open, light-filled volume. It also eliminated thousands of pounds of structural steel and building materials.
Triangular clerestory windows on the east and west sides and huge glass curtainwalls on the south and north are supported by cable trusses. These trusses complement the tensile character of the space and reveal generous roof overhangs with sweeping edge catenaries.
Entering the main terminal, travelers are struck by the enormous scale of the environment, with the roof peaks rising up to 150 feet, while an intuitive circulation system offers easy navigation from level to level. Passengers proceed from the ticketing area to an elevated walkway. This walkway encircles and overlooks an expansive Great Hall.

Sustainable by Design
Fentress’ innovative selection of roofing material and technology was a sustainable strategy that has conserved energy and saved money. The fabric roof transmits sufficient daylight to significantly reduce energy needs for artificial lighting and related cooling loads, making DIA’s passenger terminal complex one of the world’s largest daylit structures.
The roof design significantly reduced material requirements (structural steel, concrete, and embodied energy), while providing a durable, self-cleaning system. The roof’s configuration provides vents for warm air and reduces cooling energy costs.
More recently, the airport installed three large-scale solar projects, bringing the total amount of solar power produced there to 8 megawatts, the highest amount of solar generation at a commercial airport in the United States.
