As part of an effort to become certifiably green, the office tower is removing, retrofitting and replacing each of its 6,514 double-hung, dual-pane windows: That''s 26,056 panes of glass, the article stated.
The building, for four decades the world''s tallest and still the tallest in New York, is spending $13 million on windows, insulation and other upgrades to cut energy use by 38 percent and save about $4.4 million a year, the article noted.
According to the article, the building has earned a score of 90 (out of 100) from the Environmental Protection Agency''s
(EPA) ENERGY STAR
program: That means a building constructed at a size (102 stories), a time (1930) and a pace (about 14 months) not known for energy efficiency now ranks in the top 10th of commercial office buildings.
Never has a structure so old and so tall gone so green. "It''s the most recognizable building energy retrofit in the world," says Arah Schuur, director of a conservation program at former President Bill Clinton''s
foundation, The Clinton Climate Initiative
