There are hardcore real estate heads out there, probably, who are very aware of German commercial real estate company Jamestown Properties. All I can do is salute those people. For me, the Jamestown Properties of the world -- which the New York Times identifies as "an acquisition and management firm based in Cologne, Germany, and Atlanta, has invested $12 billion in commercial properties in the United States since 1983 through private equity funds for German investors" -- are shadowy entities. (I can never quite tell what Britt Daniel is writing about, but the Spoon song "Who Makes Your Money" came to mind during my reading about Jamestown) In one of their rare turns in the gbNYC spotlight, though, Jamestown is acquitting itself well. Jamestown recently announced a commitment to do up to $10 million worth of green retrofits on its entire U.S. building portfolio. Given the size of Jamestown's $4 billion portfolio, that's a lot of buildings, with such major New York City properties as LEED Gold-hopeful 1250 Broadway and Chelsea Market among them.
