Chinook Office Building
The Chinook Office Building was developed for King County by Wright Runstad & Company using a non-profit/private/public partnership model.
The building is downtown Seattle on the corner of 5th Avenue and Jefferson Street. The Chinook Office Building is a 13-story office building with a capacity of over 1400 employees once all move-ins are complete. The Chinook Office Building is in the process of seeking a Gold LEED rating for the core and shell and a Platinum LEED rating for the interior spaces.
Here are just a few of the many things that help make this buidling eligible to seek LEED certification:
For Sustainable Sites - The roof was installed with Energy Star compliant and high emissivity material called DerbBrite and a Green Roof which collectively covers 75% of the roof area.
For Water Efficiency in Landscaping - Only captured rain from the roof is used to irrigate the landscaping. Plants that do not require on going irrigation were planted.
For Energy & Atmosphere - No CFC based refrigerants were used in the building. Optimized energy performance in the building, by reducing design energy cost compared to energy cost budget for energy system. The building has an higher filtration for the HVAC system. A LEED building is 60% filtration compared to the 30% in a typical office building.
For Materials & Resources - 75% of construction waste from the construction of the building was diverted from waste and separated out to be recycled.
For Indoor Environmental Quality - Adhesives, sealants, paint and primer material used in construction were low emitting and low VOC. Carpet met the Green Label Indoor Quality Test Program. Copy rooms were built wilth full height walls and separately ventilated from office spaces. Office perimeter lighting (both open office and exterior rooms) are equiped with light sensors, so if it senses more natural daylight, the light will automatically step down in brightness.
A Touch screen directory will be installed in the building that will educate the public on the buildings LEED features, and provide current information on how the building is functioning.
