NEBB’s Certification Program

The NEBB launches the TAB Technician Qualification Program

NEBB, along with the coordination of member firms, and in an effort to improve quality, has implemented a new program called the NEBB TAB Technician program. Since 1971, it has been the intent and purpose of NEBB to certify firms and qualify persons for the purpose of performing necessary tests and inspections of building environmental systems. The TAB program qualifies certified professionally personnel who possess both management and field expertise in this area.

The qualification program for technicians has been established as a natural progression of NEBB’s original purpose. This qualification program is intended to enhance NEBB’s stature with owners and designers, while promoting the professional integrity of NEBB’s certified firms. It will also allow NEBB-certified TAB firms, which employ these technicians, to bid and perform on projects that specify the requirement for qualified technicians.

The technician program is based on the following NEBB publications: TAB Manual for Technicians, Procedural Standards for Testing, Adjusting, and Balancing of Environmental Systems and the TAB Technician Home Study Course.
