Once a year, the American Institute of Steel Construction (AISC) takes a break from its serious work of providing technical assistance to architects, engineers, and builders. Through its Innovative Design and Excellence in Architecture with Steel (I.D.E.A.S.) awards, the institute honors a few projects that use steel and display an exemplary merging of architectural expression and structural form.
ART UNDER GLASS, UNDERGROUND
In the middle of a lush, mountainside forest in Japan is a five-story structure with only a half story above ground. Yet the Pola Museum of Art in Kanagawa prefecture treats visitors to the lower floors with abundant daylight. This is because much of the building, even part of its structure, is made of glass. Designed by Koichi Yasuda, Ken Kannari, and Masao Nishioka of the Tokyo firm Nikken Sekkei Ltd., the building has won the 2003 DuPont Benedictus Award for its innovative application of laminated glass.
GREENING ROOFTOPS
Green roofs — topped with soil and living plants — have well known benefits to the buildings beneath them. They provide thermal and sound insulation and can prolong roof life. They also offer healthful benefits to their urban surroundings.
So says Steven Peck, executive director of Green Roofs for Healthy Cities. Other potential benefits of so-called "naturalized" rooftops include stormwater management, urban food production, air pollution reduction, and urban heat island temperature modification.
