Green Roofs for Healthy Cities, North America's green roof industry association, recently launched the Green Roof Professional (GRP) accreditation program. Professionals completing the program and earning the GRP designation will be certified as proficient in the areas of nonliving components, technologies, and engineered assemblies, as well as in the areas of living components, irrigation systems, and maintenance of green roof design and installation.

Candidates for GRP certification include architects, landscape architects and designers, engineers, contractors, horticulturalists, manufacturers, and roofing consultants. The certification program is designed to allow practitioners to distinguish themselves in the marketplace and to establish a high level of professionalism and multidisciplinary collaboration, as well as to increase customer confidence in green roofs.

The GRP Accreditation Exam, first administered in June 2009 at the International Greening Rooftops for Sustainable Communities Conference in Atlanta, concentrated on pre-design, design, contract management, quality assurance and support, and maintenance. Professionals will be required to maintain certification by accumulating a minimum of 16 continuing education credits every two years. Certification courses are endorsed by The American Institute of Architects, the American Society of Landscape Architects, the Association of Professional Landscape Designers, and RCI Inc. – The Institute of Roofing, Waterproofing, and Building Envelope Professionals.

Currently the exam isn't available online, but Green Roofs for Healthy Cities may change this policy in the future. In the meantime, the exam will be offered several times this fall; click here for dates and locations and for registration information. For more details on the GRP program itself, click here.
