Field and laboratory evaluation of a new ramping technique for duct leakage testing.

Author(s) : WALKER I. S., DICKERHOFF D.

Summary

The experiences from field testing have shown that ramping is more time efficient and time savings are about 10 to 15 minutes and that the repeatability uncertainty is 1% of the 50 Pa (0.2 in. water) envelope leakage flow. Field tests to determine suitability for confirming zero duct leakage have shown that the same repeatability uncertainty can also be applied to the estimation of zero duct leakage. More houses need to be field tested for repeatability to confirm the finding that envelope leakage dominates over wind induced pressure fluctuations.
