Founded in 1996 as a 501(c)(3) non-profit and launched with funding from the EPA, Green Advantage offers the only green building certification in the U.S. specifically designed for construction field personnel across trades and accredited by the American National Standards Institute (ANSI/ISO/IEC 17024). A rigorous third-party verification program, recognized nationally and internationally, ANSI is considered the hallmark of a quality certification program. Its accreditation of the Green Advantage Certified Practitioner (GACP) certification in 2013 marked the beginning of the GA commitment to achieving ANSI accreditation for all of its certification offerings.  

Through its Certified Associate and Certified Practitioner exams, Green Advantage verifies individuals’ knowledge in best practices, techniques, approaches, and materials of green building. It also prepares field personnel to better meet environmental, productivity, efficiency, safety, and budgetary goals on projects. The outcome is healthier, higher performance buildings.

And there is research to back this up. A University of Florida study found that projects utilizing larger percentages of Green Advantage certified workers are more likely to spot problems that would affect green building performance, identify cost cutting opportunities, and increase the prospects of attaining LEED certification at, or higher than, the level sought.*

Recognized by the American Institute of Architects[i], U.S. Green Building Council, Green Building Certification Institute, National Association of Home Builders, Associated Builders and Contractors, and other industry organizations, Green Advantage is applicable to multiple green building systems and requirements including:

  • LEED*
  • Green Globes
