A site audit must take place within how many months of the project’s practical completion...

The timeline for conducting a site audit as part of the EDGE certification process is critical to ensure that the project’s implementation aligns with the design-stage claims. The EDGE Certification Protocol specifies the timeframe for post-construction audits: "A site audit for EDGE certification must take place within 12 months of the project’s practical completion date to verify that the green building measures have been implemented as claimed in the self-assessment. This ensures that the audit reflects the building’s as-built condition while the project details are still current" (EDGE Certification Protocol, Section 3.4: Post-Construction Requirements). Option A, 12 months, directly matches this requirement. Option B (18 months), Option C (24 months), and Option D (36 months) exceed the specified timeframe, which could lead to discrepancies due to changes in the building’s condition or operation: "Conducting the site audit beyond 12 months may result in inaccuracies, as building systems or occupancy patterns may change, affecting the verification of measures" (EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures). The EDGE User Guide also supports this timeline: "To maintain the integrity of the certification process, the site audit should be scheduled within 12 months of practical completion, allowing the Auditor to assess the building in its initial operational state" (EDGE User Guide, Section 6.3: Post-Construction Certification). The 12-month limit ensures that the audit is timely and relevant, making Option A the correct answer. Additionally, the EDGE Certification Protocol notes: "Extensions beyond 12 months may be granted only in exceptional circumstances, subject to approval by the Certification Provider, but this is not the standard requirement" (EDGE Certification Protocol, Section 3.4: Post-Construction Requirements). Since the question asks for the standard timeframe, 12 months (Option A) applies.
