Difficult Designs: Systems That Make TAB a Challenge

Some HVAC systems look simple on paper

In the field, they tell a very different story.

CxPlanner is proud to sponsor this AABC webinar - and the topic hits close to home for anyone who has tried to balance a system that was never designed with TAB in mind.

Why this topic matters

TAB is where design decisions become real problems. A duct layout that looked fine in the model creates measurement challenges on site. A system that passed design review turns into hours of troubleshooting during commissioning.

That gap - between what's on paper and what you find in the field - is exactly where commissioning teams spend most of their time. Documenting deviations, tracking re-tests, managing the back-and-forth with design teams.

CxPlanner is built for that gap. When a TAB result doesn't match the design, you need a clear record - what was tested, when, by whom, and what happened next. That's not paperwork. That's the commissioning process working the way it should.

About the webinar

Speaker David E. Gilbert, TBE of Fluid Dynamics, Inc. will walk through real-world HVAC configurations that make TAB harder - and the design considerations that affect airflow measurement, system stability, and balance outcomes.

The webinar is hosted by the Associated Air Balance Council (AABC) - a non-profit dedicated to educating and improving TAB and commissioning professionals.
