G-8. Building Number 6.
Building number 6 has block walls with an insulated metal siding upper portion. The roof is
standing seam metal. A moderate number of fiberglass windows are installed in the upper
portions of the wall. Leakage rate versus internal pressure is shown in Figure G-6. Building
leakage rates can be calculated using equation G-6.
log(y) = C0 + C1log(x)
(eq G-6)
where: C0 = 2.8625607
C1 = 0.44496218
y = leakage rate, L/s
x = internal pressure, Pa
