    TOLEDO, Ohio, Jan. 24 /PRNewswire-FirstCall/ -- The world headquarters
 of Owens Corning (NYSE:   OC) has joined just 36 other buildings in the
 United States to earn the prestigious Silver Certification under the U.S.
 Green Building Council's (USGBC) Leadership in Energy & Environmental
 Design (LEED) Existing Building (EB) program. To achieve the award, the
 building's design and operation has met stringent standards as an
 energy-efficient, environmentally responsible and healthy place to live and
     The LEED certification of an existing building is a significant
 achievement because it is generally easier to design these features in new
 construction. The Owens Corning world headquarters is the first building in
 Toledo, Ohio, to earn this important benchmark. The building has already
 earned an Energy Star rating, which ranks it among the top 25 percent of
 energy-efficient buildings in the U.S.
     "As a company, we're committed to promoting energy efficiency and
 preserving the environment, and it's incredibly exciting for us to have our
 building recognized for being on the forefront of sustainable
 construction," said Gale Tedhams, director of sustainability for Owens
 Corning. "This recognition is confirmation that good environmental
 practices make good business sense that can pay off in a variety of ways."
     Built in 1996, the Owens Corning world headquarters was designed by
 Cesar Pelli, a renowned architect. Pelli's design of the Owens Corning
 world headquarters included advanced environmentally focused features.
     "My vision when I designed the Owens Corning world headquarters more
 than 10 years ago was of a very substantial and livable building," Pelli
 said. "I am pleased this facility provided the solid foundation needed to
 earn the recognition that the LEED Existing Building certification
     Some features that were noted during the certification process:
     Under-floor Ventilation: This design feature allows for
 energy-efficient air delivery. Because the conditioned air is delivered in
 the floor grid, controllable vents can be dropped into virtually any area,
 allowing for individual control of thermal comfort in each work area.
     Site Selection: More than 55 percent of the Owens Corning world
 headquarters site has been restored to its natural environment. During a
 period of three to five years, indigenous prairie grasses were developed on
 the grounds. Because these are natural varieties of prairie grass,
 maintenance is extremely low.
     Daylight & Views: Nearly 90 percent of the occupants in Owens Corning
 world headquarters reside in the east perimeter of the building. This
 section of the building is surrounded by a wall of glass, which provides
 optimal access to daylight that can be controlled with adjustable shades.
 In all, there are 90,000 square feet of windows at the headquarters.
     Recycling of Partitions and Carpet: Nearly all of the carpet in the
 Owens Corning world headquarters is made up of removable, reusable carpet
 squares. These are held in place by friction and gravity, using no
 adhesives. All of the internal partitions can be moved and reused. This
 means there is virtually no construction waste when new workspace
 configurations are required.
     "Owens Corning's history of leadership in helping homes and businesses
 improve their energy efficiency makes its headquarters a perfect candidate
 for the LEED Certification," said Rick Fedrizzi, president, chief executive
 officer and founding chair, USGBC.
     Developed by the U.S. Green Building Council (USGBC) in 1998, LEED
 promotes a national standard for developing high-performance, sustainable
 buildings that protect the environment. LEED certification recognizes
 innovative building designs that are environmentally responsible business
 models for energy efficiency and resource conservation. For more
