Established in 1971, NEBB (National Environmental Balancing Bureau) is the premier international certifying association for firms and individuals that deliver high performance buildings and systems. Strict specifications and requirements exist for building systems designs and installation, but efficient operations are often an afterthought. NEBB Certified Firms, Professionals, and Technicians uphold the highest standards in building systems commissioning and processes, technical retro-commissioning of existing buildings, and testing, adjusting and balancing.
