The role of an EDGE Expert is well-defined within the EDGE framework to clarify their responsibilities and qualifications. The EDGE Expert and Auditor Protocols provide a precise description: "An EDGE Expert is an individual accredited by the EDGE Certifier (such as GBCI or other authorized certification bodies) who can serve as a consultant to project teams, advising on the selection of green building measures, preparing the self-assessment in the EDGE software, and guiding the project toward certification" (EDGE Expert and Auditor Protocols, Section 2.1: Roles of EDGE Expert). Option B, an individual accredited by the EDGE Certifier who can serve as a consultant, directly matches this definition. Option A (a consultant who can issue a preliminary EDGE certificate) is incorrect, as Experts do not issue certificates: "Only the EDGE Certification Provider can issue a preliminary certificate, not the EDGE Expert" (EDGE Certification Protocol, Section 3.3: Certification Decision). Option C (an individual who can serve as both an auditor and a consultant upon EDGE Committee approval) is also incorrect, as this violates conflict-of-interest rules: "An individual cannot serve as both an EDGE Expert and Auditor on the same project, even with committee approval, to avoid conflicts of interest" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). Option D (an individual accredited by the EDGE Operations and Management Team) is wrong, as accreditation is handled by the Certifier, not the Operations team: "The EDGE Operations and Management Team oversees the program, while accreditation of Experts is managed by the EDGE Certifier" (EDGE Certification Protocol, Section 1.3: Program Structure). The EDGE User Guide further supports this: "EDGE Experts are accredited professionals who consult on projects, having passed the EDGE Expert exam administered through the Certifier" (EDGE User Guide, Section 6.4: Working with EDGE Experts). Thus, Option B best describes an EDGE Expert.
