LEED Gold Certification
Location: Portland, OR
Project Size: 227,000 sq.ft.
Project Description: Science Building 2, a four-story building with three basement levels totaling 220,000 square feet, was built in 1971. NWESI provided TAB and commissioning services for the remodel of this facility, which included both substantial equipment replacement and a 7,130 SF addition for hazardous materials. The building remained open during the project and work was conducted in phases. Numerous constant speed fume hood exhaust fans were replaced with four variable volume exhaust fans with heat recovery. Fume hoods were replaced with high efficiency variable volume hoods. After the remodel, supply and exhaust to each room is now controlled with airflow control valves that adjust to changes in fume hood sash position and room occupancy.
