New Testing, Adjusting and Balancing Procedural Standard – Ninth Edition now available!

The NEBB Procedural Standard for Testing Adjusting and Balancing of Environmental Systems (Procedural Standard) establishes a uniform and systematic set of criteria for the performance of the testing, adjusting and balancing of environmental or Heating, Ventilating and Air-Conditioning (HVAC) systems.

Today’s buildings provide highly controlled, sustainable energy efficient indoor environments. These buildings include very sophisticated mechanical systems created by a team of skilled professionals. A key member of this team is the NEBB Certified Testing, Adjusting and Balancing (TAB) Firm (CF).

This standard and these procedures are intended as the minimum NEBB requirements that a NEBB Certified Firm must follow when performing TAB procedures. When contract documents do not specify details for Testing, Adjusting and Balancing, this procedural standard becomes the minimum standard to which a NEBB Certified TAB Report must meet. Conversely, contract documents may include more stringent requirements as necessary, in which NEBB Firms must meet this standard plus any additional, more stringent, requirements as dictated by the contract documents. This Procedural Standard has been carefully compiled and reviewed by the NEBB TAB Committee.
