<br /> 502.4.5 Building Air Leakage Testing: All new construction and additions over 750 sq.ft.need to have a blower door test done and the
<br /> resulting air leakage should be less than 0.00030 Specific Leakage Area(SLA)when tested at 50 pascals(0.2 inch w.g.)of depressurization.Testing
<br /> can be done any time after rough in and after installation of penetrations of the building envelope,including penetrations for utilities,plumbing,
<br /> electrical,ventilation and combustion appliances(and sealing of these penetrations)have been completed.Building officials can request that the
<br /> test be conducted while building department staff is present.The blower door test results need to be recorded on the certificate that is required in
<br /> Section 105.4
<br /> Exemptions:
<br /> 1.Additions less than 750 square feet
<br /> 2. Once visual inspection has confirmed the presence of a gasket(see section 502.4),operable windows and doors manufactured by small business
<br /> shall be permitted to be sealed off at the frame prior to the test.Specific Leakage Area(SLA)shall be calculated as follows
<br /> SLA =(CFM50 x 0.055)/(CFA x 144)
<br /> Where:
<br /> CFMso =Blower door fan flow at 50 pascal pressure difference
<br /> CFA =Conditioned Floor Area of the housing unit,converted to square inches
<br /> During Testing:
<br /> Exterior windows and doors,fireplace and stove doors shall be closed,but not sealed.
<br /> Dampers shall be closed, but not sealed; including exhaust, intake, makeup air, back draft, and the flue dampers; interior doors connecting
<br /> cored oon d ',pact'', shall be open; access hatches to conditioned uawl spaces and conditioned attics shall be opened: doors connecting to
