The CoStar Group’s list of the top 50 Manhattan office leases (by square footage) that were finalized in 2008 appears in this week’s issue of Crain’s (though it isn’t available online). By our count, 7 of these 50 leases were inked for space in green office buildings. Importantly, the top two leases overall were in green buildings (1515 Broadway and 375 Hudson Street, respectively). We’ve written about a number of these buildings before, and present each lease below along with links to pertinent posts at gbNYC. We also set forth the tower’s third-party certification status (if any), tenant, landlord, and total square footage of the deal.
