Air Sealing Guidance for LEED-EBOM IEQp2

Blower Door Testing 

In order to achieve LEED certification in multi-family buildings, LEED-EBOM IEQp2: Environmental Tobacco Smoke (ETS) Control requires that blower door testing be performed to verify that smoke will not penetrate into other areas of the building. This requires proper sealing of all penetrations in ceilings, walls, and floors, and blower door testing verifies this design and construction compliance.

Guidelines for performing blower door testing 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 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 ruling for multi-family buildings allowed for random sampling in one of every seven units. Results must demonstrate less than 1.25 square inches...
