Testing, Adjusting & Balancing (TAB) of HAVC Systems

According to NEBB Procedural Standard for Testing, Adjusting and Balancing of Environmental Systems (2019-Ninth Edition), Testing, Adjusting and Balancing (TAB) is “A systematic process or service applied to HVAC systems, and other environmental systems, to achieve and document air and hydronic flow rates”.

TESTING

Testing is the base of our business, whether it is in new construction or already existing buildings, with chillers, boilers, air handlers, package units, exhaust and ventilation fans, circulating pumps, and many other equipment.

ADJUSTING

The varying of system flows by partially closing balancing devices, such as dampers and valves, and varying fan speeds to achieve optimum system operating conditions within design and installation limitations.

BALANCING

Balancing is the methodical proportioning of air and hydronic flows through the system mains, branches, and terminal devices using acceptable procedures to achieve the specified airflow or hydronic flow within installation, testing and design limitations.

The services provided by Evolution Engineering Services under this field are:

– Complete air and hydronic testing and balancing of large, medium, and small commercial air conditioning systems (i.e. VAV, multi-zone, double-duct, single zone with reheat systems).

– Balancing air and water distribution systems.
– Adjusting the total system to provide the specified quantities.
– Performance testing of clean room systems.
– Testing hospital systems with special requirements (i.e. surgery, isolation, sterile rooms).
– Indoor Air Quality (IAQ) Measurements.
– Duct pressure testing for leakage.
– Outside air CFM adjustment.
– Performing accurate electrical measurements.
– Establishing quantitative performance of all equipment.
– Verifying automatic controls.
– Measurement of sound and vibration levels.
