Established in 1971, the National Environmental Balancing Bureau (NEBB) is the premier international certification association for firms that perform testing, adjusting and balancing (TAB) of heating, ventilating and air-conditioning systems in addition to building systems commissioning, sound and vibration measurement, retro-commissioning, fume hood testing and cleanroom performance certification.  NEBB is proud to have over 600 certified firms with over 900 qualified supervisors world-wide.

NEBB-certification disciplines are anchored by NEBB Procedural Standards that provide guidelines for work to be performed. NEBB enhances the educational experience of each discipline (testing, adjusting and balancing, building systems commissioning, sound and vibration measurement, retro-commissioning, fume hood testing and cleanroom performance testing), by providing technical manuals, training materials, and offering seminars.
