Testing, Adjusting and Balancing

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.

Why Testing, Adjusting and Balancing Certification?

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. 

 

The objectives of NEBB’s TAB certification program are:

NEBB’s Testing, Adjusting, and Balancing program provides certification of firms and individuals that meet the criteria established by NEBB.
