(a) Any person or entity to whom this Article 38 applies, as defined in Section 3805, shall submit to the Director an Enhanced Ventilation Proposal, prepared by, or under the supervision of, a licensed mechanical engineer or other individual authorized by the California Business and Professions Code Sections 6700-6799 (Professional Engineers Act) to design mechanical ventilation systems that meet the requirements of this Article 38 and San Francisco Building Code Section 1203.5. An Enhanced Ventilation Proposal shall include the name, title and license number of the person submitting such proposal.
(b) The Enhanced Ventilation Proposal shall explain how the project will achieve the standards mandated by this Article 38 and accompanying the Rules and Regulations as described and updated according to Section 3809, San Francisco Building Code Section 1203.5, and any relevant amendments or revisions thereto. The Enhanced Ventilation Proposal shall include a statement signed by the person who prepared it, in accordance with the requirements of Section 3807(a), certifying that in his or her judgment the ventilation system proposed will be capable of achieving the protection from particulate matter (PM2.5) equivalent to that associated with MERV 13 filtration (as defined by ASHRAE standard 52.2). In updates to the Rules and Regulations, the Director may specify additional or alternative protective equivalents as technology and research dictate.
(c) The Director shall review the Enhanced Ventilation Proposal and may require additional modification or justification prior to the Director's approval. The Director shall issue a letter to the Department of Building Inspection Permit Services Energy/Mechanical Plan Review Section identifying and attaching the letter describing the approved Enhanced Ventilation Proposal.
(d) Building permit documents submitted to the Department of Building Inspection shall incorporate all designs and details necessary for the construction of the approved Enhanced Ventilation system. The Department of Building Inspection shall review submitted plans to assure compliance with the Director-approved Enhanced Ventilation proposal and shall not issue permits for the construction, installation, or modification of the Enhanced Ventilation systems unless it is in compliance with the approved proposal.
