Brookfield Properties Corporation announced that its recently redeveloped 1225 Connecticut Ave. office building in Washington, D.C., has earned LEED Platinum certification. The developers say its is the first redeveloped office building in the Eastern United States to achieve LEED Platinum certification. The eight-story building features a glass curtainwall that rises from the northwest corner of 18th Street, N Street and Connecticut Avenue. 

The glazing elements, in fact, are features that helped the project earn LEED certification. The curtainwall system, which was manufactured and installed by Harmon, incorporates PPG’s Solarban 70 XL and the building itself features floor-to-ceiling windows to allow for maximum natural lighting.

Brookfield Properties performed a complete redevelopment of 1225 Connecticut Ave. upon acquiring the building in 2006 by investing $32 million to transform it into a sustainable, class A asset. Environmentally sensitive features were incorporated into both the base building and the interior fit-outs as the asset was being redeveloped. Ninety-two percent of the material from the existing building was used in the redevelopment process, preserving the embodied energy in the original construction of the property.

“1225 Connecticut Ave.’s LEED Platinum certification demonstrates tremendous green building leadership,” says Rick Fedrizzi, president, chief executive officer and founding chair of the U.S. Green Building Council (USGBC). “The urgency of USGBC’s mission has challenged the industry to move faster and reach further than ever before, and Brookfield’s redevelopment project serves as a prime example [of] just how much we can accomplish.”
