Thermographic Survey
Functionality and Importance
Thermographic survey is a technique used to analyse buildings by detecting infrared rays. It requires special thermal imaging cameras that visualise surface temperatures and detects anomalies to uncover possible defects in the construction.
A thermographic survey is used to assess the construction quality of buildings, in regards to:
To name a few.
Thermography in BREEAM
There are credits available in the Man 04 issue in BREEAM for carrying out a thermographic survey, although it does have some requirements.
The most important one is a 10 °C temperature differential between the internal and external envelope. Every area of the building to be surveyed has to abide by this rule, for the whole duration of the test which typically takes up to 4 hours. Also, wind speeds must be below 5 m/s and there must be no rain for the survey to be considered valid.
