Testing, Adjusting, and Balancing (TAB): ACG Building Systems Commissioning Guideline Preview

Abstract:

Testing, Adjusting, and Balancing (TAB) is a cornerstone of the building systems commissioning process, ensuring HVAC systems achieve design intent and operate at peak efficiency. This session draws from the ACG Building Systems Commissioning Guideline to highlight best practices for integrating TAB agencies into commissioning workflows during both design and construction phases. Attendees will learn how commissioning providers (CxPs) and TAB professionals can collaborate to optimize system performance, streamline communication with design and construction teams, and enhance documentation and verification practices. By understanding the essential role of TAB in system balanceability, diagnostics, and controls integration, participants will gain actionable strategies to improve project outcomes, owner satisfaction, and long-term system performance.

Learning Objectives

  1. Explain the role of TAB professionals in the commissioning process and identify how qualifications-based selection supports project success and HVAC system performance.
  2. Describe TAB integration during the design phase, including specification review, system balanceability assessment, and establishing requirements for special testing and training.
  3. Evaluate TAB responsibilities during the construction phase, such as developing TAB plans, coordinating with controls contractors, and producing phased reports to support commissioning team activities.
  4. Apply best practices for TAB verification and reporting, including aligning TAB data with commissioning plans, conducting diagnostic verification testing, and facilitating timely resolution of deficiencies.
