JPMorgan Chase is making its 50-story headquarters at 270 Park Avenue in Manhattan more environmentally-friendly, Reuters reports, and it’s doing it ten stories at a time, starting at the top with rooftop vegetation. Also on the roof, drains will collect rain water that will be stored in a 55,000 gallon basement tank to later be used in toilets. The company estimates that more efficient lighting, heating and cooling systems will reduce energy consumption by 30 percent. Ultimately, the company hopes for a platinum LEED rating.
JPMorgan joins a list of other major companies retrofitting old office buildings into more eco-friendly spaces. Citigroup, in particular, has taken an inventory of energy use of all of the company’s buildings, adopted power-saving measures such as turning off escalators in lobbies, and is redesigning its bank branches to include more natural lighting and recycled materials.
