Annex E (informative) Detection of the leakage location

Detecting the location of leakages is necessary to reduce the leakage area and to estimate the leakage distribution of buildings. The methods are as follows. a)

Subtraction method

The envelope area and/or devices to be detected are covered air barrier sheet. After measuring the leakage a rea w ith and without the air barrier sheet, the difference between the both provides the leakage area to be known. b)

Using the in frared thermo viewer

During the test (depressurization), a thermal camera can be used to localize air infiltration as long as t here is a temperature difference between indoor a nd outdoor. c) Using smoking The s moke is generated to visua lize the a irflow through the envelope, devices, etc. and to detect the location of the leakage. This method might need the practical skill, e.g. smoke generation rate. Also, it might be possible to feel the airflow around the devices, etc. on the envelope with fingers, but it is not consistent because of the individual variation. d) Using an air velocity meter During the test (pressurization or depressurization), an air velocity meter can be hold aga inst places on the envelope area or devices where one might suspect leakages. If the instrument shows an air velocity, it is an indication of leakage.
