Air Forest is a temporary public pavilion installed in City Park, Denver, Colorado, USA, for Dialog:City, an arts and cultural event during the Democratic National Convention 2008.
Air Forest is a 56.3m long, 25m wide pneumatic structure, composed of 9 hexagonal canopy units, at 4m height. These units are interconnected as one large piece of fabric, which are then inflated from the 14 blowers that are located at the base inside its 35 columns. These columns are 5m apart, and are weighed down by dirt and lighting elements which are also inside the columns, which light up at night and provide a public space after dark as well. 6 each of these pneumatic columns form a unit as they are connected in a hexagonal manner creating a circular opening from their inside perimeter.
Out of the 9 total hexagonal units formed, 3 of them are left open-air while the remaining 6 have vortex-shaped meshes that hang from them, providing shades for the public from the harsh sunlight. The nylon fabric is coated with a gradient of silver dots, whose reflective surface mimics the colors of its surrounding environment, as well as providing a playful dotted shadow on the people under the structure.
