Why Certify?

“The power of the (Green Advantage) tool lies in creating a common vocabulary and set of goals for an often ill-aligned design and delivery team.”

Rives Taylor, FAIA, LEED AP BD&C

Everyone knows it takes a high performance team to build a high performance building. Yet so many green building teams are not equipped with the knowledge and tools to truly deliver buildings that perform as designed.

The Green Advantage Certified Professional (GACP) and the Green Advantage Certified Associate (GACA) credentials, are the only ANSI accredited certifications that are applicable across trades, regardless of the green building rating system, standard or code being pursued. Similarly, the Green Advantage Certified Curtainwall Installer credential is the only ANSI accredited curtainwall installer certification in the industry. It requires possession of either the GACA or GACP credential as well as passing rigorous curtainwall-specific written and performance exams. All three of these certifications ensure that workers across trades have proven competencies in the means, methods, materials, and best practices to successfully deliver green building projects.

At Green Advantage, we realize that green design + green construction = green building, and we’re here to help you deliver.

So whether you want to advance your career, add to your company’s prowess, earn a LEED credit, or do your part to create a more sustainable world, GA can help you get there. To learn how, click on the role that best fits you.
