Results shall be reported as Specific Leakage Area (SLA) and shall be calculated as follows:
SLA = (CFM50 x 0.055)/(CFA x 144)
Where:
CFM50 = Blower door fan flow at 50 Pascal pressure difference
CFA = Conditioned Floor Area of the housing unit

2009 Washington State Energy Code reference:
502.4.5 Building Air Leakage Testing: Building envelope air leakage control shall be considered acceptable when tested to
have an air leakage less than 0.00030 Specific Leakage Area (SLA) when tested with a blower door at a press of 50 Pascals
(0.2 inch w.g.). Testing shall occur at any time after rough in and after installation of penetrations of the building envelope,
including penetrations for utilities, plumbing, electrical, ventilation, and combustion appliances and sealing thereof. When
required by the building official, the test shall be conducted in the presence of department staff. The blower door test results
shall be recorded on the certificate required in Section 105.4.
EXCEPTIONS: 1. Additions less than 750 square feet.
2. Once visual inspection has confirmed the presence of a gasket (see Section 502.4), operable windows
and doors manufactured by small business shall be permitted to be sealed off at the frame prior to the test.
