Sustainable Site
- BMP was followed through use of a silt fence, stabilized construction entrance, sediment basin and other measures
- Bicycle storage and shower/ changing rooms available for alternative transportation for 180 occupants
- Preferred parking and program carpool and alternative fuel vehicles to serve 3% of occupants
- Parking capacity does not exceed minimum code requirements and provides preferred parking for carpools at 10% of occupants which reduced parking stalls required by 6%
- Reduced site disturbance through open space to encourage habitat
- 48% of non roof areas contain high albedo materials to reduce the heat island effect
- 100% of roof meets emissivity requirements and complies with Energy Star to reduce heat island effect.
Water Efficiency
-
Innovative waster water use of rain water harvesting for building sewage conveyance
-
Over 40% water use reduction through use of rain water harvesting for building sewage conveyance
Energy and Atmosphere
- Optimized energy efficiency through a 65.61% energy reduction compared to ASHRAE 90.1-1999
- Super insulated envelope, geothermal heat pump with an EER of 19 heat recovery, demand based ventilation and lower lighting power density
- HCFC and Halon free HVAC (heating ventilation and air conditioning) equipment
- Plan for sub metering water and energy usage which document the process in place for verifying system performance and calibrating system components
- Green power purchased to meet 58% of the building electrical needs for over of 2 years
Materials and Resources
- Occupant recycling
- Diverted 81.65% of construction waste through effective waste management plan
- 21.89% of total building materials by value contain recycled materials
- 55.98% local and regional materials manufactured regionally
Indoor Environmental Quality (IEQ)
- CO2 sensors monitor to outside ambient levels and increased ventilation if exceeding thresholds
- Construction IAQ Management plan was in compliance with SMACNA guidelines, during construction, MERV 8 filters were installed at grilles
- Construction IAQ Management plan before occupancy – the project conforms with the required IAQ testing protocol
- 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
Innovation and Design
- Exemplary performance in local materials- achieved 55.98% of the total materials by cost were manufactured within 500 miles
- Exemplary performance in recycled content- achieved 21.89% of the total materials by cost
- Exemplary performance in rain water harvesting for building sewage conveyance adding to a 40% water savings
- Exemplary performance in IEQ – all furniture and finishes are Greenguard IAQ Certified
- LEED accredited professionals participating on the project
