Testing, Adjusting and Balancing

Discover the benefits of NEBB’s TAB certification – and how you can achieve it

Allowing HVAC systems to meet or exceed the performance levels of their design specifications, Testing, Adjusting and Balancing helps provide environmentally efficient buildings.

 

Using specialized instruments, this methodical regulation of the system is intended to evaluate equipment and system performance, and proper adjustment of the balancing devices when necessary.

 

It provides building owners and tenants with optimal environmental performance, while minimizing costs through efficiency.

What is
Testing, Adjusting and Balancing?

Testing, Adjusting, and Balancing (TAB) is a vital process in the management and optimization of heating, ventilation, and air conditioning (HVAC) systems, particularly focusing on ductwork.  


TAB ensures that an HVAC system operates efficiently and effectively by systematically verifying and fine-tuning its performance.


Practical Applications of TAB

TAB is crucial in both new constructions and existing buildings. For new constructions, TAB ensures that the HVAC system is set up correctly from the start, meeting design specifications and providing optimal performance. In existing buildings, TAB can address issues such as uneven heating and cooling, high energy bills, and poor indoor air quality.  

 

For instance, in a commercial building with extensive ductwork, TAB can identify and correct airflow issues that might lead to hot and cold spots, thereby improving occupant comfort and reducing energy consumption. Additionally, TAB helps in maintaining regulatory compliance and achieving sustainability goals by ensuring the HVAC system operates at peak efficiency. 

Why Get NEBB-Certified in 
Testing, Adjusting and Balancing?

Building owners and tenants are concerned that the environmental performance of buildings must be optimal while the operating cost should be minimal. 
 
These goals can only be accomplished when a building’s HVAC and hydronic systems are properly balanced. Three major steps used to achieve the proper operation of the HVAC and hydronic systems and a desirable climate are testing, adjusting, and balancing (TAB).

The purpose of NEBB’s TAB certification program is to offer tangible proof of competent firms and professionals qualified in the proper methods and procedures for testing building systems for optimum performance.
