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. TAB 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.
