Abstract: |
A proposal for standardized thermal images.Statements on the thermal transmittance of building details based on thermal images should be delivered by means of standardized "thermograms". The presented "QualiThermo" method gives the guidelines for the temperature scaling. The empirically developed method has been validated during a project supported by the Swiss Federal Office of Energy (SFOE) and enhanced further. For this purpose a test house was instrumented with temperature sensors and measured for several weeks. For certain short periods the building was simultaneously monitored by two infrared cameras. By means of numerical simulations and consecutive sensitivity analysis the major parameters influencing the accuracy of heat losses of building details were identified. "QualiThermo" is a helpful method at the disposal of thermography practitioners which - within certain limits - allows comprehensible and reproducible analysis of thermograms. Out of the findings of this project practical procedures and tips can be deduced to support practitioners producing correct thermograms during a winter night and adequate interpretation. |
