Alcoa Kawneer Products Help Put Innovative Colorado Courthouse on Track for LEED Gold Certification

December 9, 2010

NORCROSS, Ga.–Alcoa (NYSE: AA) announced today that its Kawneer business has supplied
architectural aluminum products that are integral to the new
Lindsay-Flanigan Courthouse in Denver meeting Leadership in Energy and
Environmental Design (LEED) requirements. Kawneer’s 1600 SS Unitwall™
curtain wall helped the project with maximum daylight goals and several
LEED requirements in the Materials & Recourses category. Kawneer also
used recycled aluminum billet, which contributed to recycled content
requirements. The new, five-story, 317,000-square-foot courthouse is on
track for LEED Gold certification and also won the 2010 American
Institute of Architects Denver Honor Award for design excellence.

Architectural firm klipp Architecture Planning Interiors selected
Kawneer curtainwall for the East side of the building to represent the
transparent nature of justice. To maintain the integrity of the design
and the concept of transparency and light, the architect did not want to
incorporate a steel support behind the wall, but rather have it appear
to float. The complex wall design incorporates several setbacks, folds
and slopes.

Working with the architect and Kawneer engineers, Denver-based glazer,
Trainor Glass, created a 3D model of the wall to ensure that all
components could fit together and be supported. “Because the design
called for a curtain wall on a tilted plane, and to create the illusion
of floating, it had to be top-hung from a secondary steel structure,”
said Bill Trainor, project manager with Trainor Glass.

In addition to providing daylighting, Kawneer’s 1600 SS Unitwall™
incorporates GLASSvents® throughout the judges’ chambers that
integrated seamlessly with the building’s design.
