A building owner tells an EDGE Auditor that water-efficient faucets are in the building’s restrooms.

EDGE Auditors must adhere to strict protocols ensuring that all claimed measures are supported by verifiable evidence, especially during audits. The EDGE Expert and Auditor Protocols state: "If a claimed measure, such as water-efficient faucets, lacks supporting documentation like specifications or manufacturer’s data sheets, the Auditor must exclude the measure from the project assessment. The Auditor is not permitted to test equipment, substitute evidence, or mandate replacements, as their role is to verify, not rectify, the Client’s submission" (EDGE Expert and Auditor Protocols, Section 4.2: Evidence Verification). Option A, exclude the faucets from the project, aligns with this protocol, as the lack of specifications prevents verification. Option B (test the faucets’ flow rates) is incorrect, as Auditors cannot conduct tests: "Auditors are not responsible for testing equipment; they must rely on provided documentation" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option C (require the owner to replace the faucets) oversteps the Auditor’s role: "Auditors cannot mandate changes to the project; they assess what is submitted" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). Option D (find a product with the same parameters) is also prohibited: "Auditors cannot substitute or assume evidence on behalf of the Client" (EDGE Expert and Auditor Protocols, Section 4.2: Evidence Verification). Thus, the Auditor should exclude the faucets (Option A).
