Towards quantitative thermography for buildings - Indoor measurement of thermal losses.

The current construction trend which calls for minimizing buildings’ heat losses by means of thick heat coats leads to the problem of limiting energy consumption for cooling, especially in Mediterranean climates. The control of internal gains and direct radiant energy which enters through windows during the summer season requires rather precise knowledge of the heat exchange dynamics which occur among the walls of rooms. This paper concerns the development of a methodology aimed at the estimation of radiative and convective thermal flux components in room walls. The proposed procedure entails practical, one-side, indoor measurements, which combine dynamic thermography with traditional contact thermal measurements. This provides an effective means for estimating the thermal flux at each of the points depicted by the thermal image.
