The consulting firm CodeGreen Solutions has announced that 5 Penn Plaza – which dates from 1915 – has earned a Silver rating under LEED for Existing Buildings: Operations & Maintenance. Working with the tower’s property manager, CBRE, CodeGreen’s efforts resulted in a 20 percent reduction in water consumption and an ongoing consumables recycling rate of 73 percent. 5 Penn Plaza also installed energy-efficient T8 lighting with occupancy sensors; timers on individual electric hot water heaters per floor; and occupancy sensors in restrooms throughout.

CodeGreen also assisted 5 Penn Plaza in earning a 2012 Energy Star label. The tower’s score increased to 77 during the LEED-EB: OM performance period through an NYSERDA Cost Shared Energy Audit and Retro-Commissioning Study. Both studies will help the building comply with New York City’s Local Law 87 (which requires buildings larger than 50,000 square feet to undergo an energy audit and retrocommissioning) in 2013.

Originally designed by architects John & Edward Larkin, the 24-story, 650,000-square-foot beaux-arts office tower dates from 1916 and was once known as the Printing Crafts Building after one of its primary tenants: the Charles Francis Press, which was one of the country’s largest printers from the 1880s through the Depression. The Printing Crafts Building was originally designed specifically for multiple tenants from the printing industry: today, its historic roots remain evident in the printer symbols above 5 Penn Plaza’s main entrance on Eighth Avenue, between 33rd and 34th Streets.
