LEED Gold Design

SUSTAINABLE SITES

  • Open space has been created for over 54% of the site area. This includes site landscaping, a central courtyard and rooftop amenity spaces.

  • Approximately 24% of the total site has native or adapted vegetation providing habitat due to the project’s large green roof and landscaped courtyard.

  • The site is in a transit-oriented location close to a Metro Station.  In, addition being in a densely developed urban area provides ample opportunity for walking, bicycling, and other non-vehicular transportation.

  • Stormwater runoff has been reduced by 49% for the 2-year 24 hour storm.  Runoff is reduced due to the project’s green roof.

 

WATER EFFICIENCY

  • Low flow water fixtures installed in the building save over 40% compared to the LEED baseline. Water savings from efficient fixtures save an estimated 7,433,150 gallons of water per year. Plumbing fixture flow rates are below:

  • o Lavatory faucets – 0.5 gallon per minute

  • o Toilets – 1.28 gallons per flush

  • o Showers – 1.5 gallons per minute

  • o Kitchen Faucets – 1.5 gallon per minute

·       The landscape design results in additional site water savings due to the use of drip irrigation and native/adaptive plants. Water savings from the landscape design are an estimated 60% or 28,707 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 90.1-2007 energy standards. A whole building energy model was developed to determine the building’s energy performance and savings. The projected energy savings are 26% in energy cost compared to the ASHRAE 90.1-2007 baseline. Savings come from the following measures:

  • o High-efficiency VRF HVAC systems

  • o Water-cooled dedicated outside air systems (DOAS)

  • o Increased wall insulation with R-13 batt + R-8.4 continuous insulation

  • o High efficiency condensing boilers for domestic hot water

  • o 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 over 24% of the building materials used in the project (by cost). Additionally, 20% of building materials have been locally sourced and manufactured within 500 miles.

  • Approximately 87% of construction waste has been diverted from landfills for a total of 3,947 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 the use of low-VOC paints, adhesives, sealants, and flooring. These permanently installed finishes were low VOC materials per LEED standards.
