Back in mid-2009, Beacon Capital’s 1211 Avenue of the Americas (on Sixth Avenue between West 47th and 48th Streets) earned LEED-EB Silver certification from USGBC. At 45-stories and two million square feet, the tower is the largest commercial office building that has been certified to date under the LEED for Existing Buildings rating system (either Version 2.0 or Operations and Maintenance). In February, Beacon signed Axis Re, a division of Axis Capital, a Bermuda-based reinsurance company, to a 121,000-square-foot lease on the building’s 24th through 26th floors. Asking rents for the space were approximately $65 per square foot (slightly above overall Midtown asking rents, which were $57.97 per square foot in February, up from $55.82 in January). Overall Manhattan asking rents in February were $47.61 per square foot, up from $48.31 in January.
