Back in September, we noted a report in Crain’s that Al Gore’s investment firm, Generation Investment Management LLP, was looking for LEED-certified office space in New York City. Today, Generation announced that it has secured a 5,000-square-foot lease on the 48th floor of the Durst Organization’s Bank of America Tower, which expects to receive the first-ever LEED Platinum rating for a commercial high-rise once it opens up next May. As we’ve noted previously, asking rents at the Midtown tower, which was designed by Cook + Fox, are hovering around $185/square foot; it’s unclear how much Gore’s firm agreed to pay for the space, but as of July, this was the asking price for the only two remaining floors in the building. (By way of comparison, according to Cushman & Wakefield, the average asking rent for Class A office space in Midtown is $70/square foot).
