Co-Op City undergoes 130,000 window replacements

The basics: Installation crews are nearing completion on a multi-year project at Co-Op City in the Bronx, N.Y.,  to replace about 130,000 windows. The $60 million project, which started in 2007 and is scheduled for completion in 2012, is taking place while residents continue to occupy the 35 high-rise buildings that make up Co-Op City. During the project, the old fenestration systems are being replaced with highly energy efficient heavy-commercial aluminum windows, sliding glass and swing terrace doors. Co-Op City was built in the late 1960s, and has more than 15,000 apartments and 50,000 residents.
