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.
