As part of its ongoing Green initiative, the Brooklyn Navy Yard is set to begin installing 90 wind- and solar-powered lamp posts. What makes the lamp posts even greener is the fact that they are designed and built by Navy Yard tenant Duggal Visual Solutions, which plans to convert a one-story, 30,000-square-foot building in the Yard into a two-story, 60,000-square-foot LEED Platinum certified facility for manufacturing eco-friendly products. Other fun facts: The street lights will save the BNYDC $600,000 dollars or so in the first year and $11,000 a year going forward on its electricity bill.
