-  * ** The outdoor air temperature is approx. 6.46 °C ** as measured at the surface of the bags hanging from the scaffolding. The surfaces of these bas have reached a temperature equilibrium with the outdoor air; therefore they neither give off heat nor do they absorb heat.   +  * ** The outdoor air temperature is approx. 6.46 °C ** as measured at the surface of the bags hanging from the scaffolding.

   * ** The temperatures measured for the areas of the facade that have already been insulated are very uniform** and rather similar to that recorded for the bags – rendering the bags barely noticeable in the thermal image. Nevertheless, the insulated surface is slightly warmer than the surrounding objects. Since the thermal image was taken before sunrise, direct or indirect sunlight would not be the cause for the slightly higher temperatures of 6.81 °C on average.  In fact, the temperature difference is due to small heat losses which remain even with the wall being insulated. The uniform image in the area that has already been insulated is a good sign, showing that the insulation has been properly applied.   * ** The temperatures measured for the areas of the facade that have already been insulated are very uniform** and rather similar to that recorded for the bags – rendering the bags barely noticeable in the thermal image.
