TAB consists of testing, adjusting, and balancing.
Special, carefully calibrated instruments are used to measure temperatures, pressures, rotational speeds, electrical characteristics, velocity and air and water qualities for an evaluation of equipment and system performance. Devices such as dampers and valves are adjusted along with fan speeds and pump impeller sizes to achieve maximum specified system performance and efficiency. System fluid flows are methodically regulated and balanced to achieve desired airflow or water flow. Technicians coordinate, witness, verify and report on the work of specialist contractors and manufacture's representatives under the supervision of the NEBB Certified Systems Commissioning Agent. All mechanical and electrical systems are prepared for active service.
