Testing, Adjustment & Balancing

Testing, Adjusting, and Balancing (TAB) involves measuring and adjusting air and water flows to meet design requirements. The TAB process is comprised of using test instruments, sensors and monitors to verify appropriate temperatures, airflow and other characteristics within the HVAC system. Testing, Adjusting, and Balancing is a vital step for complex air and hydronic systems within buildings and throughout campuses to ensure HVAC systems are optimized for occupant comfort, energy efficiency, indoor air quality, and manufacturing processes.

Most TAB work involves testing, measurement, and establishing performance benchmarks. Key examples of these activities include quantifying air & hydronic volumetric flow rates, verifying heat transfer performance, and adjusting ventilation and air exchange rates.
