In an effort to become certifiably green, The Empire State Building is replacing every one of its 6,514 windows. Each one is double-hung and dual-paned which means you’re talkin’ 26,056 panes of glass.
Who’s the lucky contractor? Serious Materials from Sunnyvale, California.
Each pane is retrofit and has a film within the panes of glass to improve energy efficiency. All of this work is being done overnight so there’s no interruption to all those busy New Yorkers as they work away by day.
According to USA Today, the $13.3 million spent on windows is projected to cut their energy consumption by 38% and yield savings of $4.4 million a year. The Environmental Protection Agency's "Energy Star" program has given the Empire State Building a score of 90 out of 100. Pretty good for an 80 year old 102 story building!
