From its location on the west side of Manhattan, most south, west and north-facing tenants have unobstructed views of the Hudson River.One Penn Plaza is currently owned by Vornado Realty Trust. It was previously owned by Helmsley-Spear Inc., which sold the building for $420 million in the late 1990s.In 2009, plans were made to install a cogeneration plant in order to heat the building more efficiently. By 2010, it was reported that when the new plant was activated, it nearly cut the building's carbon output in half.More than 80 percent of the action in the 2011 independent film Margin Call was shot on the 42nd floor of the building, which had recently been vacated by a trading firm.
