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 occupants
Reduced site disturbance through open space to encourage habitat
81.17% of roof meets emissivity requirements and complies with Energy Star to reduce heat island effect.
Exterior lighting has been designed according to IESNA RP-33 for light pollution reduction
Water Efficiency
Landscape design uses native and drought tolerant plantings which do not require a permanent irrigation system
Water use has been reduced by 24.06% through the use of low flow kitchen sinks and lavatories
Energy & Atmosphere
Additional commissioning was performed for the building
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 86.43% of construction waste through effective waste management plan
14.31% of total building materials by value contain recycled materials
26.85% local and regional materials manufactured regionally
20.64% local and regional materials extracted regionally
8.47% of total building materials by value contain rapidly renewable materials
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, after construction, MERV 13 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 were used
Low emitting composite wood products were used
Indoor pollutant source control
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
Daylight and views are available to 93% of the critical visual task spaces
Innovation and Design
Green education through informative CD and outreach efforts, such as the participation in a number of conferences including the "Greening the Heartland" conference, GreenBuild 2006, Illinois Parks and Recreation Conference, Illinois Sustainable Living Fair, and Energy 2006. The project will also be open for tours.
