Anatomy of an Award: IES illumination Award of Merit.

Travelers at Jacksonville International Airport can catch a glimpse of the friendly skies even before boarding a plane--they just have to look up. Running through the center of the new concourses A & C, an 8-ft-wide skylight provides ambient light for walkways and boarding areas. For client Jacksonville Aviation Authority, David Laffi tte and Carl Baehner from Reynolds, Smith & Hills designed the skylight to maximize daylight and improve visual comfort. Tinted, insulated, laminated glass allows a 72 percent visible light transmittance, while the custom metal armature below blocks low-level sunlight to reduce glare. An emergency sprinkler system and supplemental electric lighting are integrated into the armature so that "they don't impede the structure," says Laffitte. "We wanted to let the daylight come in as unobstructed as possible."
