Sustainable Site

  • Brown field redevelopment
  • Urban redevelopment area
  • Bicycle storage and shower/ changing rooms available for alternative transportation
  • Preferred parking and program for carpooling and alternative fuel vehicles to serve 12% of occupants
  • Reduced site disturbance through open space to encourage habitat
  • Storm water management through BMP of vegetated filter strips, wet extended detention pond, constructed wetlands and grassed swales and a strict policy against the use on site of products containing phosphorus
  • 100% of non roof areas will be shaded in 5 years and impervious areas are provided light colored concrete to reduce heat island effect.
  • 100% of roof meets emissivity requirements and complies with Energy Star to reduce heat island effect.

Water Efficiency

  • Landscaping uses native and adaptive vegetation and does not require not require permanent irrigation system
  • 38.66% water use reduction through use of low-flow and water efficient fixtures and appliances

Energy & Atmosphere

  • Optimized energy efficiency through a 23.2% energy reduction compared to ASHRAE 90.1-1999
  • Higher insulation values, heat recovery, efficient windows
  • Under floor air distribution and more efficient HVAC equipment
  • Lower lighting power density and day lighting,
  • Additional commissioning
  • Plan for sub metering water and energy usage
  • HCFC and Halon free HVAC (heating ventilation and air conditioning) equipment
  • Green power purchased to meet 100% of the building electrical needs for over of 2 years

Materials & Resources

  • Occupant recycling
  • Diverted 59.84% of construction waste through effective waste management plan
  • 12.78% of total building materials by value contain recycled materials
  • 36.8% local and regional materials manufactured regionally
  • 17.2% harvested ore extracted locally
  • 59% of wood based materials were certified in accordance with FSC principles and criteria
    Indoor Environmental Quality (IEQ)
  • CO2 sensors monitor to outside ambient levels and increased ventilation if exceeding thresholds
  • Under floor air delivery system provides increased ventilation effectiveness in compliance with ASHRAE 129-1997
  • Construction IAQ Management plan was in compliance with SMACNA guidelines, during construction, MERV 8 filters were installed at grilles
  • Low emitting adhesive and sealants were used
  • Low emitting paints were used
  • Low emitting carpet was used
  • Indoor pollutant source control
  • Controllability of non perimeter temperature, ventilation and lighting systems
  • Designed for thermal comfort compliance with ASHRAE 55 – 1992 for relative humidity and temperature
  • Thermal comfort monitoring system installed for compliance with ASHRAE 55 – 1992 for relative humidity and temperature
  • 2% day lighting factor for 75.1% of occupied space for critical visual tasks achieve
  • 99% of all occupants have direct line of sight to views for all space occupied for critical visual tasks

Innovation and Design

  • Green Building Education
  • Exemplary performance in green power to meet 100% of the building electrical needs for over of 2 years
  • Exemplary performance in 100% of non roof areas will be shaded in 5 years and impervious areas are provided light colored concrete
  • Exemplary performance in low emitting materials – all furniture and finishes are Greenguard IAQ Certified
  • LEED accredited professionals participating on the project
