LEED Gold Version 2.0

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
