    USPS Maintains one of the Largest Green Roofs in NYC

    The USPS’s Morgan Processing and Distribution Center on Ninth Avenue, between 29th and 30th Streets, transformed its seventh floor rooftop into a 2.5-acre green roof with benches and skyline views for its employees. The new roof is expected to last 50 years and will provide better insulation, cutting heating and cooling costs by about $30,000 a year; further, the landscaping on the roof is expected to help reduce storm-water runoff into the sewage system by as much as 75 percent in the summer and 40 percent in the winter.

    Hudson Yards Allows For New York City’s Continued Growth

    Directly to West of the 34th Street Hub are the Hudson Yards, Manhattan’s latest frontier for major urban buildout. The City of New York, the Metropolitan Transportation Authority, and the State of New York are collaborating to create a vibrant, pedestrian-friendly, and transit-oriented mixed-use district. Following the rezonings of the Hudson Yards area and the Western Rail Yards area from commercial to residential, the area now has the capacity for approximately 26 million square feet of new office development, 20,000 units of housing, of which almost 5,000 units will be affordable units, 2 million square feet of retail, and 3 million square feet of hotel space. In addition, the No. 7 subway line will be extended from its current terminus at Times Square to a new terminal station at 34th Street and 11th Avenue, knitting this new developing into New York City’s already world-class mass-transit system.

    As part of the redevelopment of this area Related Co. and Kohn Pederson Fox are developing the largest commercial building in New York City, representing 5.5 million square feet and consisting of two tapered office towers atop a superblock bounded by 10th Avenue, 33rd Street, Hudson Boulevard and 30th Street. The development will represent a northern anchor to the High Line  and is expected to achieve LEED Platinum certification.

    Empire State Building’s Energy Retrofit Yields Impressive Results

    The Empire State Building is undergoing a comprehensive retrofit which will save 38% of the building’s energy, save (a minimum of) 105,000 metric tons of CO2 over the next 15 years, and save $4.4 million annually[1], thereby showing the potential for large-scale commercial buildings to achieve  a high-level of energy and CO2 reduction cost-effectively.  The retrofit was motivated by the building ownership’s desire to: 1) Prove or disprove the economic viability of whole building energy efficiency retrofits; 2) Create a replicable model for whole building retrofits; and 3) Reduce greenhouse gas emissions.

    Given that buildings are responsible for 38% of CO2 emissions in the US[2] and approximately 75% of CO2 emissions in New York City[3], the building sector must contribute to reducing greenhouse emissions. Consulting, design, and construction partners Clinton Climate Initiative, Johnson Controls Inc., Jones Lang LaSalle, NYSERDA, and Rocky Mountain Institute worked with the Empire State Building Company to help make the landmark building potentially the most environmentally conscious office tower built before World War II[4]. Anthony Malkin of the Empire State Building Co. ensured the transparency of the process so that other building owners – particularly those with pre-WWII or landmark properties – would have an example to follow in pursuing their own sustainability retrofits, as tens of billions of square feet remain in office buildings worldwide for which owners have made little or no progress in the areas of energy efficiency and sustainability.

    In order to achieve the 38% reduction in energy, the following 8 upgrades/retrofits/adjustments have been implemented or are in the process of being implemented:

    • WINDOWS: Re-manufacture of existing insulated glass units (IGU) within the Empire State Building’s approximately 6,500 double-hung windows to include suspended coated film and gas fill.
    • RADIATIVE BARRIER: Installation of more than six-thousand insulated reflective barriers behind radiator units located on the perimeter of the building.
    • TENANT DAYLIGHTING / LIGHTING / PLUGS: This measure involves reducing lighting power density in tenant spaces, installing dimmable ballasts and photosensors for perimeter spaces, and providing occupants with a plug load occupancy sensor for their personal workstation.
    • CHILLER PLANT RETROFIT: The chiller plant retrofit project includes the retrofit of four industrial electric chillers in addition to upgrades to controls, variable speed drives, and primary loop bypasses.
    • VARIABLE AIR VOLUME AIR HANDLING UNITS: This measure consists of replacing existing constant volume units with variable air volume units by using a new air handling layout (two floor-mounted units per floor instead of four ceiling-hung units).
    • DIRECT DIGITAL CONTROLS: The measure involves upgrading the existing control systems at the Empire State Building.
    • DEMAND CONTROL VENTILATION: This project involves the installation of CO2 sensors for control of outside air introduction to chiller water and DX Air Handling Units.
    • TENANT ENERGY MANAGEMENT: This project will provide tenants with access to online energy and benchmarking information as well as sustainability tips and updates.
