Abstract
A method for determining leakiness in a building envelope of a building, including the steps of generating a sound signal, acquiring a thermography image of at least a part of the building envelope, acquiring an acoustic image of the same part of the building envelope, and superimposing the thermography image and the acoustic image to determine the leakiness of the building envelope.
Claims16
A method for determining the locations of leakiness in a building envelope of a building, comprising the steps of:
- generating a sound signal;
- acquiring a thermography image of at least a part of the building envelope;
- acquiring an acoustic image of the same part of the building envelope by spatially resolved detection of the sound signal;
- and
- superimposing the thermography image and the acoustic image to locate the leakiness of the building envelope.
(canceled)
A device for acquiring a thermography image and an acoustic image for determining the locations of leakiness in a building envelope, comprising
- a thermography camera for acquiring the thermography image, and
- a microphone array with a plurality of microphones, the microphones being arranged at a fixed distance from one another and preferably at a fixed distance relative to the thermography camera, the acoustic image being acquired by means of the microphone array.
