The NEBB is the latest association to lend its endorsement to the AHR Expo 2003, January 27-29 in Chicago. The association is one of 17 endorsing associations that have allied with the Expo.

The National Environmental Balancing Bureau (NEBB) is a nonprofit organization, founded in 1971 by contractors in the heating, ventilating and air conditioning industry. NEBB exists to help architects, engineers, building owners, and contractors produce great buildings with hvac systems that perform in ways they have been visualized and designed. NEBB establishes and maintains industry standards, procedures and specifications for work in its various disciplines that include: Testing-Adjusting-Balancing (TAB)- Air and Hydronic Systems, Sound and Vibration (S&V) Measurement, Cleanroom Performance Testing (CPT), and Building Systems Commissioning - Hvac and Plumbing Systems.

NEBB joins a highly diverse group of endorsing associations that bring many different segments of the industry together in one show. The endorsing associations join long-time co-sponsors American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the Air-Conditioning and Refrigeration Institute (ARI), and honorary sponsor Heating, Refrigeration and Air-Conditioning Institute of Canada (HRAI) in supporting the exposition.
