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
