About NEBB
Established in 1971, the National Environmental Balancing Bureau (NEBB) is the premier international certification association for firms that deliver high performance building systems. Our members perform testing, adjusting and balancing (TAB) of heating, ventilating and air-conditioning systems, commission and retro-commission building systems, execute sound and vibration testing, and test and certify laboratory fume hoods and electronic and biological cleanrooms.
Building owners, engineers and contractors seeking ways to cut costs through the proper design, installation and optimal performance of heating, ventilation, air conditioning and refrigeration systems, benefit from working with NEBB certified professionals, who are required to complete extensive training and testing programs in order to attain certification status.
