Which of the following is a primary resource for the EDGE Auditor when performing the...

During a site visit for post-construction certification, the EDGE Auditor relies on specific tools to verify compliance. The EDGE Expert and Auditor Protocols specify: "The primary resource for an EDGE Auditor during a site visit is the EDGE Auditor’s checklist, which provides a structured list of items to verify, including the implementation of selected measures, alignment with the self-assessment, and compliance with EDGE standards" (EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures). Option C, EDGE Auditor’s checklist, matches this description as the key resource guiding the audit process. Option A (EDGE software) is a tool for assessment, not a resource for the site visit: "The EDGE software is used for self-assessment and desk audits, not directly during site visits" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option B (roof insulation U-value) and Option D (Window to Wall Ratio) are specific data points the Auditor may verify, not primary resources: "U-values and WWR are elements to check, not tools for the Auditor" (EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures). The checklist ensures all aspects of the project are systematically reviewed, making it the primary resource (Option C).
