SUSTAINABLE SITES

Open space has been created for over 35% of the site area. This includes site landscaping, a green roof and rooftop amenity spaces.

The green roof, which is accessible at roof amenity areas, consists of native or adapted vegetation which requires minimal irrigation and maintenance.

The site is less than half a mile to a Metro Station. In, addition being in a densely developed urban area provides ample opportunity for walking, bicycling, and other non-vehicular transportation.

WATER EFFICIENCY

Low flow water fixtures installed in the building save over 35% compared to the LEED baseline. Water savings from efficient fixtures save an estimated 4,559,918 gallons of water per year. Plumbing fixture flow rates are below:

   - Lavatory faucets – 1 gallon per minute

   - Toilets – 1.28 gallons per flush

   - Showers – 1.5 gallons per minute

   - Kitchen Faucets – 1.8 gallon per minute

The landscape design results in additional site water savings due to use of drip irrigation and native/adaptive plants. Water savings from the landscape design are an estimated 78% or 17,145 gallons of water in the peak summer watering month compared to the LEED baseline.

ENERGY & ATMOSPHERE

The project has been designed to meet and exceed ASHRAE 90.1-2010 energy standards. A whole building energy model was developed to determine the building’s energy performance and savings. The projected energy savings are 23% in energy cost compared to the ASHRAE 90.1-2010 baseline. Savings come from the following measures:

   - High efficiency VRF HVAC systems serving apartments and common areas.

   - Rooftop HVAC units with energy recovery.

   - High efficiency condensing boilers for domestic hot water.

   - Lighting controls including occupancy sensors in amenity areas, stairwells, and corridors. Amenity spaces also have daylight sensors in areas near windows.

MATERIALS & RESOURCES

Recycled content makes up 15% of the building materials used in the project (by cost).

Approximately 84% of construction waste has been diverted from landfills for a total of 1,375 tons of construction material recycled or reused.

INDOOR ENVIRONMENTAL QUALITY

Construction IAQ management was conducted to protect ductwork and HVAC systems from construction debris and contaminants generated during construction.

Another measure to improve indoor air quality was use of low finishes and insulation. These permanently installed finishes were low VOC materials per LEED standards.
