Guidelines for performing blower door testing (for IEQp2 in NC, CS, and CI rating systems) require that you follow ANSI/ASTMVoluntary standards development organization which creates source technical standards for materials, products, systems, and services-E779-03 Standard Test Method and that sampling be performed in accordance with progressive sampling methodology defined in Ch. 4 of the Residential Manual for Compliance with California’s 2001 Energy Efficiency Standards. A LEED Credit Interpretation Request (CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide) for multifamily buildings has allowed for random sampling in one of every seven units. Results must demonstrate less than 1.25 square inches leakage area per 100 square feet of enclosure area (sum of all wall, ceiling, and floor areas).
Based on these comments it seems to me that you are saying blower door tests are required for any residential projects, whether smoking is allowed within the building or not. Does this answer my question already posted to NC - IEQp2?
Brittany, the guidelines posted here are not intended to address the question you posted over on IEQp2. The guidelines here are for your use if you need to pursue air sealing and blower-door testing. We still think you might be able to avoid this in your project—have you proceeded further with that or learned more?
