Acceptance Test Technician
Certification Program

Acceptance tests ensure code compliance and promote optimization of efficiency and performance for nonresidential buildings. They serve to determine whether specific building components, equipment, systems, and interfaces between systems conform to criteria set forth in the 2013 Building Energy Efficiency Standards (Section 10-103-A and Section 10-103-B of the 2013 Building Energy Efficiency Standards PDF).

More information about Acceptance Test can be found in Chapter 13 of the 2013 Nonresidential Compliance Manual.

Acceptance Test Technicians

Who are these Technicians?

Acceptance Test Technicians (ATTs) are building specialists, trained and certified by Acceptance Test Technician Certification Providers (ATTCPs). They conduct required tests, submit results and certificates to enforcement agencies, and are employed by certified ATT Employers. These Employers are required to have specialized training by an ATTCP.

There are two types of certified technicians: lighting controls and mechanical systems.

Training and Certification

Training and certification are new requirements in the 2013 Building Energy Efficiency Standards, to address the low historical effectiveness of testing of nonresidential building systems, due to construction trades not being uniformly familiar with equipment and methods used to conduct acceptance tests.

Who can become an ATT?

Those who are in industries including:

  • Electrical Contractors
  • Certified General Electricians
  • Professional Engineers
  • Controls Installation & Startup Contractors
  • Certified Commissioning Professionals
  • HVAC Installers
  • Mechanical Contractors

ATT Effective Thresholds

The thresholds include a minimum number of technicians certified to conduct the tests, and reasonable access to certification by technicians in a majority of the industries mentioned above.

Lighting Controls:

As of June 18, 2014, thresholds have been met for lighting controls, and ATT certification requirements will become effective July 1st, 2014.

Mechanical Systems:

Currently, a mechanical Contractor (or their field technician) is allowed to conduct acceptance testing without being certified as an ATT. However, training is ongoing, and once thresholds for training the industry have been met, it will be a requirement to obtain certification, to work as an ATT.


The following Provider(s) have been approved to offer training and certification:
