100 Gold Street is touting itself as the first green residential building in Brooklyn’s Vinegar Hill neighborhood. Designed and developed Anthony Morena’s REDD Group, the 5-story, 10-unit condominium development is currently under construction just a few blocks east of the Manhattan Bridge and is incorporating a variety of sustainable design features. 9-foot windows will provide ample natural daylight and Manhattan views for residents; gas-fired, wall-hung boilers in each unit should save up to 40 percent on heating costs. Recycled glass tile will be used for backsplashes in each kitchen and zero-VOC paints throughout are being supplied by Brooklyn-based Ivy Coatings. Other materials sourced locally include recycled-content roof pavers manufactured by Saugerties-based Unity Creations and hand-blown light fixtures by Beacon-based Niche Modern. Green features will also include on-site bicycle storage, dual flush toilets, and compact fluorescent lights throughout. REDD also intends to purchase renewable energy credits to offset the building’s projected energy consumption during its first year of operation.
