Effective storm water management reduces amount of rainwater dumping into NYC’s sewer system by 30%
Tower rises from behind the preserved facade of the old 6 story structure. 85% of original structure was recycled for future building
Original cast-stone facades are restored. Construction materials were chosen with no harmful chemicals and manufactured with recycled content
WATER EFFICIENCY 4 POINTS
Air conditioning: Rainwater is collected to be reused to freshen and humidify the air inside of the lobby Regular water use: Low Flow Fixtures are used to reduce consumption of potable water
Irrigation: Potable water reduction of 1.2 million gallons/year or 30% approximately
Cooling tower: Potable water reduction of 165,000 gallons/year or 100%
WATER EFFICIENCY 4 POINTS

ENERGY & ATMOSPHERE 6 POINTS
Cooling - Centrally located on 28th floor
Two 1200-ton electric centrifugal chillers
One 400-ton electric centrifugal chiller
One four-cell roof cooling tower
Three plate & frame heat exchangers
Typical Electric Centrifugal Chiller.
Free cooling Condenser water system fan coil units Radiant floor cooling Water cooling for “Icefall”
Zero use of CFC refrigerants
Outside air is utilized for 75% of the year
Variable speed drives on all pumps
Variable speed blowers on air-handling units
CO² and humidity sensors
100% outside air purge capability
A central heating plant which includes a pressure reducing steam station for:
Domestic hot water heaters, air-handling units, steam-hot water exchanges, unit heaters, fan coil units, radiant floor heating, and perimeter fin tube radiation
ENERGY & ATMOSPHERE 6 POINTS
SymmetrE™ is used as the Building Automation System for:
Temperature, mechanical and electrical service and distribution systems, lighting controls, emergency generator and uninterruptible power supplies
All appliances are Energy Star
ENERGY & ATMOSPHERE 6 POINTS
Interior offices have motion sensors which turn off lights and computers when the office is vacant Perimeter offices have light sensors which control the amount of artificial light based on the amount of natural light in the offices The elevator system was also designed with energy savings in mind
MATERIAL & RESOURCES 5 POINTS Designated space for
collection & storage of recycled materials
Separate collections of glass, plastic, metals, office paper, newspaper, cardboard, and organic waste. Cardboard balers and aluminum can crushers can be used to further enhance the recycling program
Construction Waste Management: Divert 50% from Disposal for 1 point
or
Construction Waste Management: Divert 75% from Disposal for 2 points
20% of materials manufactured regionally
Products produced within 500 miles of the site
MATERIAL & RESOURCES 5 POINTS
Using local resources saves energy
Supports the use of indigenous & local resources and reduces the environmental impacts resulting from transportation
INDOOR ENVIRONMENTAL QUALITY 13 POINTS Interrupt contamination pathways
Sequence installation to avoid contamination of absorptive materials such as insulation, carpeting, ceiling tile and gypsum wallboard.
INDOOR ENVIRONMENTAL QUALITY 13 POINTS
Conduct an IAQ baseline test after construction, prior to occupancy
Superior IAQ improved worker productivity
Expensive and complicated cleanup procedures
INDOOR ENVIRONMENTAL QUALITY 13 POINTS
Reduce the quantity of indoor air contaminants
Low-e carpet (Green Label)
Millwork - composite wood substrates with NO added urea formaldehyde
Low-e VOC sealants & adhesives (GS-36) and paints (GS-11)
Clear Wood Finishes (SMAQMD #1113)
INDOOR ENVIRONMENTAL QUALITY 13 POINTS
Low-e glass allows for internal spaces to be flooded with natural light while keeping out the invisible solar radiation that causes heat
Efficient design allows for corner space to be conference room and not office
INNOVATION & DESIGN PROCESS 5 POINTS
Structure: The tower's distinctive framework is a "diagrid" of interlinked triangles, so structurally efficient that the building uses 20 % less steel than conventional designs require
Education: Allowing group tours into the Hearst Tower and educating them on the importance of LEED buildings
Green Housekeeping: The use of environmentally friendly products to clean and maintain the tower
LEED Certification plaque etched into the front glass door
A LEED AP as part of the team during the entire design and construction phases also earns one point towards certification.
