Beus Center for Law and Society

ASU Beus Center for Law and Society, Tempe AZ

Project Description:

The Beus Center for Law and Society (BCLS) is the new home to the Sandra Day O’Connor College of Law at Arizona State University, as well as several other organizations. The building space uses form and function to connect students, visitors, and the general public to the role of justice in society. The BCLS was designed to be inviting, engaging, and accessible to everyone who is interested in learning about the law, its effect on our daily lives, and the many services and resources available through ASU and other BCLS partners

Scope of Work:

TMCx was retained by ASU to provide LEED Fundamental and Enhanced Commissioning services. As such, TMCx provided design document and submittal review and comment, sequence of operation development with the design and contractor.

Project Snapshot:

  • Owner:  Arizona State University
  • Project Size:  260,000 sq. ft.
  • Construction Cost:  $93M
  • Design Team: Jones Studio / Buro Happold
  • Year of Completion:  2017


HVAC System included 516 active and passive chilled beams and under floor air distribution (UFAD) throughout the facility served by VAV air handling units.
Heating and cooling provided by the campus chilled water system and local hot water boilers.
Lighting controls included occupancy sensors and daylight harvesting.

Challenges & Successes:

  • Issue: Proper balancing was a challenge for this project due to the amount of chilled beams. In most cases, the units were not meeting design flow with the fan operating at 100% speed
          Resolution: TMCx worked together with the TAB contractor to properly calibrate air flow sensors and to configure the operating parameters of the chilled beams to ensure air flow design was met.
  • Issue: Several AHUs were found to not meet the design discharge wet bulb temperature. Outside air was above scheduled design and units were providing 20% more air than design.

          Resolution: Having found that the chilled beam units were flowing greater than design air flow, possibly due to balancing techniques, TMCx worked with Buro Happold and the construction team and determined that AHU static pressures could be reduced to decrease total air flow while still allowing correct chilled beam air flow. Additionally there was a small sequence change to fan coils, which increased static pressure/AHU airflow.
