University of Oregon’s Matthew Knight Athletics and Events Arena

Tetra Tech’s High Performance Building Group delivered commissioning services to the University of Oregon’s Matthew Knight Arena, a state-of-the-art athletics and events facility in the heart of one of the west coast’s most active college towns. Most notably, the arena features a 32-foot by 26-foot, 65,000-pound center hung scoreboard—the largest in college sports.


  • Size: 400,000 square feet
  • Client/Owner: University of Oregon
  • Architect: ZGF Architects
  • Contractor: Hoffman Construction
  • Completion Date: 2011


The Matthew Knight Arena faced many challenges common to similar large sports and events arenas. Inefficiencies in all systems occur in these types of facilities. Tetra Tech played a significant role working with the design and construction team to attain Matthew Knight Arena’s functional and sustainability goals. Our commissioning team tested the functionality and energy efficiency of all the arena’s HVAC, electrical, and controls systems and equipment. Attendees experience a greater level of comfort than exists at court level because of the isolation of the perimeter concourse’s HVAC air supply. A high-efficiency lighting system features occupancy sensors that save energy when the stands are empty and only the court is in use for practice. Advanced controls allow for displacement ventilation across the court surface for low capacity events.

Tetra Tech’s efforts allowed the arena to achieve LEED Gold certification rather than its initial goal of LEED Silver. Tetra Tech continues to monitor the arena’s energy—improving its operability and reducing its ongoing maintenance costs.

  • Isolation of the perimeter concourse HVAC air supply from air to the interior bowl
  • Installation of occupancy sensors for practice court lighting
  • Installation of Big Ass Fans™ for temperature destratification in the arena bowl and practice courts used for air circulation to reduce cooling energy consumption
  • Installation of high-efficiency lighting system
  • Installation of energy recovery ventilators for free heating/cooling energy otherwise released to the outdoors
  • Controls alignment for displacement ventilation across the court surface for low-capacity events, such as practices and high school summer camps
