Sustainable Sites

  • Brownfield redevelopment site
  • Near Environmental Protection Agency's (EPA) (EPA) Regional Office and public transportation
  • Bike racks, showers and changing rooms provided

Water Efficiency

  • Rainwater capture/reuse system supplies graywater for toilets, cooling tower makeup and landscape faucets
  • Sustainable landscaping (xeriscaping)
  • Low-flow plumbing fixtures

Energy & Atmosphere

  • Low E glass for all windows
  • Energy-efficient T-5 and halogen lamps for indirect lighting and T-8 lamps for direct lighting
    5 modular natural gas-fired boilers
  • 3 small, water-cooled chillers; one primary variable-speed chiller and one that employs water heat recovery
  • Variable volume fume hoods

Materials & Resources

  • 97% percent recycled-content building materials & furnishings
  • Construction recycling diverted 72% of debris from landfills
  • 76% of construction and furnishing materials from within 500 miles

Indoor Environmental Quality

  • High indoor air quality with low-VOC (volatile organic compounds) materials
  • Sequencing of finishes installed absorptive materials last
  • During construction, the heating, ventilating and air conditioning (HVAC) system and duct work were sealed to prevent infiltration of dust or contaminants
  • High-ceiling, open-bay offices with large clerestory windows allow natural light into the building

Innovation & Design Process

  • Energy efficient equipment reduces laboratory process loads
  • Use of captured stormwater reduces potable water use in cooling tower by 15%

“As we went through the planning process, GSA saw how close we were getting to qualifying for Gold.  They participated in additional engineering that allowed us to get over the hump.”
