The most distinctive building of New York’s skyline, the Empire State Building, is going green after a $20million revamp, according to reports. It is estimated the “eco-friendly makeover” will reduce energy costs by $4.4 million (£2.7m) a year.
The refurb included refurbishing all 6,514 windows of the iconic skyscraper, saving an estimated $410,000. As well as new sensors to control lighting and air flow which is meant to save waste, the building also has a rebuilt cooling system which is more efficient – and should save $675,000 a year.
The ESB is already New York’s largest commercial user of green energy, getting 100% from renewable sources.
