Manhattan District 1/2/5 Garage Awarded LEED® Gold

Manhattan District 1/2/5 Garage, the Department of Sanitation’s facility located at the corner of Spring Street and West Street, has been awarded LEED® Gold. The new home of three district garages, this 425,000 sf building achieved LEED Gold certification for implementing measurable strategies and solutions aimed at achieving high performance in: sustainable site development, water savings, energy efficiency, materials selection, indoor environmental quality as well as innovation and design process. The building was designed by Dattner Architects in association with WXY Architecture + Urban Design.

 “The collaboration with the Department of Sanitation and the architects at Dattner and WXY was extraordinary, creating an environmentally progressive building that meets the challenge of being a good neighbor in a vibrant community. [Manhattan Districts 1/2/5 Garage] also demonstrates how to build a welcoming workplace that also responds to the resiliency lessons learned since Hurricane Sandy.— Commissioner Peña-Mora, NYC DDC, 1/22/2016

Sustainable Sites:  The “fifth façade,” the 1.5 acre green roof, reduces heat-island effect, enhances storm water retention and thermal performance, and promotes biodiversity of native species.  The bio-diverse plant variety ensures that something will be in bloom at any given time during the growing season, providing food for pollinating insects, and contributing to habitat restoration. The green roof does not require permanent irrigation.

Water Efficiency: A projected 77% reduction in potable water usage is achieved through a combination of low-flow fixtures and an extensive water harvesting system that captures and treats rainwater and waste steam condensate for use in fixtures and truck wash.

Energy & Atmosphere: A projected 35.8% energy cost savings is achieved through a combination of Lighting & HVAC Control Strategies, Efficient Lighting Fixtures and Solar Shading to reduce solar heat gain.  Energy usage is also offset by the use of a 275 kW Steam Turbine Generator, which produces electricity through the step-down process from the high pressure steam in the street to the working pressure steam in the building.  The City of New York purchases Green Power, from wind-generated source, for 35% of the building’s electric usage.

Materials & Resources: Over 40% of the building materials used on the project were manufactured with Recycled Materials. Over 20% of the building materials used on the project were manufactured with materials that were sourced and manufactured within 500 miles of the project site. Virtually all (99.88%) of the wood products used in the millwork are certified in accordance with the Forest Stewardship Council.

Indoor Environmental Quality: Only low-VOC Adhesives, Sealants, Paints and Coatings were used on the project. Air Quality management protocols were put in to place during Construction to protect the building’s ventilation system and indoor air quality has been  tested to ensure that the air did not contain pollutants remaining from Construction. Exterior views are provided for over 90% of the buildings occupied spaces.

Innovation & Design Process: A benchmark project for New York City’s Active Design program, which promotes the use of architectural design to encourage movement and improved fitness among the facility users, bicycle racks and changing rooms are provided to encourage bike usage among the employees. Exemplary Performance Innovation Credits were awarded for the project’s Water Use Reduction, Access to Public Transportation, and extent of Green Roof.
