Enclosure Area: Record the total exterior enclosure surface area including walls, fl oor
and ceiling from design plans as supplied by the Architect of Record (AOR). Verify the
dimensions used by the AOR in the calculations match as-built conditions and that the
arithmetic was performed correctly.

2.14
Confi rm uniform interior pressure distribution by establishing at least 30 Pa and using a minimum of four
pressure monitoring stations with one common exterior pressure monitoring station. Measure pressures at the
four interior stations to ensure the interior pressure is within +/– 10% of target value. List interior stations
and pressures measured:
