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 commissioning, 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 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.


NEBB’s certification training and testing programs are the most rigorous in the industry. NEBB-certified firms and professionals have the skills necessary to measure the efficiency of building systems, but also the practical knowledge and communication skills to create practical solutions for business owners.
