A Green Residential Building in Brooklyn, NY.

  • 439 Metropolitan Ave. strives to integrate high performance green design with comfortable and aesthetic building design. Among the many green aspects of this project the building features; radiant floor heating in conjunction with continuous filtered ventilation with heat recovery which will bring air quality to near HEPA-standards, a 96% efficient condensing boiler, a well insulated enclosure and private photo voltaic solar panel arrays for each unit. In addition, the building will utilize solar heat as a passive energy source due to the north-south orientation of the building. The commercial unit will also utilize storm water for toilet flushing.
