American Architects Name Top Ten Green Buildings for 2008
April 30, 2008
The American Institute of Architects (AIA) and its Committee on the
Environment have named the top ten examples of sustainable
architecture and green building design solutions for 2008. The
efficient buildings draw on a variety of energy-saving technologies,
including efficient lighting, daylighting, passive solar heating,
natural ventilation, thermal mass, earth berms, and green roofs. For
mechanical heating, the buildings draw on a range of technologies,
including a wood-pellet boiler, radiant floor heating, and ground- and
air-source heat pumps. Cooling technologies include demand-controlled
ventilation and fans with variable-frequency drive motors. Four of the
buildings employ displacement ventilation, which provides air at more
moderate temperatures at low velocities, in a way that gradually
displaces the stale air in the room with the fresh ventilation air.
One of the top ten buildings, the Aldo Leopold Legacy Center even
features "Earth tubes," pipes buried below the foundation to moderate
the temperature of incoming ventilation air.
The buildings range from a temporary, modular building for exhibits to
a high-rise condominium. Most are institutional buildings, including a
library, a visitor center, two K-12 school buildings, two university
buildings, and the headquarters for a foundation. The AIA's Top Ten
Green Projects program is sponsored in part by DOE and the Energy Star
program, a joint effort of DOE and the U.S. Environmental Protection
Agency. The projects will be honored at the AIA 2008 National
Convention and Design Exposition in Boston, Massachusetts, in mid-May.
