ASU Block 12

ASU Block 12, Tempe AZ

Project Description:

The Block 12 project plan encompasses ground-level eateries; a 200-seat auditorium for “Experience ASU” tours that will double as a classroom when not in use for tours; several general classrooms that can support 40, 80 and 120 students; as well as a new home for the Del E. Webb School of Construction.

Scope of Work:

TMCx was retained by ASU to provide LEED Fundamental and Enhanced Commissioning services.

As a result, TMCx coordinated the design reviews with the design team to provide “lessons learned” which resulted in sequence of operation modifications and facilitating a smooth turnover / acceptance process.

Project Snapshot:

  • Owner:  Arizona State University
  • Project Size:  130,000 sq. ft.
  • Construction Cost:  $XXM
  • Design Team: Architekton / Henderson
  • Year of Completion:  2014


HVAC systems included VAV Air Handling Units serving VAV terminal units and chilled beams throughout.  Renewable Energy systems included solar heating hot water.  Emergency Power Distribution as well as lighting controls were also commissioned.

Challenges & Successes:

  • The sequence of operation included a requirement that the chilled water return temp be above 56 deg. F. As a result of our design review, it was determined that this sequence would not fulfill this requirement and subsequent conversations between the design and construction teams took place and a revised sequence was agreed upon.  As a result, the requirement was achieved and verified during functional testing.
  • TMCx was contracted to commissioning 20% of the VAV terminal units. However, due to the high failure rate, each unit was tested for proper performance based on over 70 issues involving VAV operation listed
  • Issues were identified with the chilled beam system included the chilled water pump leaking, heating pump differential control pipes leaking, controls programming not complete, and heating side being air locked. TMCx worked with the Contractors to resolve these issues.
