About NEBB

Learn 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 of heating, ventilating and air-conditioning systems, commission and retro-commissiong building systems, execute sound and vibration testing, building enclosure testing, test and certify laboratory fume hoods, and electronic and biological cleanrooms.

Building owners and tenants are concerned about their buildings’ environmental systems, so performance must be at a maximum while costs should be at a minimum. These “green” goals can be accomplished only when a building’s environmental system is properly tested, balanced and/or commissioned by a NEBB Certified Professional or Technician. NEBB’s function is to establish, promote and maintain high quality standards through certification of Firms, Professionals and Technicians.

There are more than 650 NEBB Certified Firms worldwide and over 1800 NEBB Certified Professionals and Certified Technicians. They are recognized by the industry and building owners as specialists having the skills necessary to measure the efficiency of building systems, and as the leaders in practical knowledge and communication skills for creating customized solutions for business owners. NEBB Certification offers tangible proof of their qualification in the procedures outlined for NEBB disciplines.

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.  For the latest NEBB Brochure:  NEBB_brochure_07_01_2014

NEBB’s credibility is built by maintaining integrity through high standards, quality programs and demonstrated capabilities of its certified firms. This is achieved through NEBB’s Quality Assurance Program (QAP).

The NEBB QAP ensures swift, single-source mediation and resolution of disputes between NEBB Certified Professionals and their customers. Under the QAP, NEBB will intervene on any project if the customer feels that a NEBB Certified Firm has failed to perform in accordance with NEBB Procedural Standards (NEBB Operational Procedures_15th Edition_BOD approved_10-17-2015 _ FINAL).
