In comparison, in the thermal image of the external door demonstrates losing a heat of the church. Moreover, the thermal image shows the difference of temperature on the wall (purple) and metal door (orange) as maximum10 °c and minimum around 2°c
Next point, leaking of a heat on the arched shutter windows show losing a heat clearly. As the result by the image, the window shows an uncontrolled leaking of heat. Not only the windows, but also on all paths of the windows seen as a lighted orange and orange on the image that shows leaking of a heat from inside. Both of the bell window and timber, does not have any protective material for saving a heat.
In this point, as the thermal image shows differences of the material that is not relate with the leaking of a heat. In some thermal image shows many dark dots and points on the image. As the same result, there does not demonstrate any thing that relevance to thermography. But it shows difference of material as a flint on the façade.
The last point, as the result showed that losing a heat via all sites of lower windows as a maximum on the façade of window is 9°c as lighted orange. This factor might lead to increasing a cost of electricity and over leaking of dampness though the tower. There is a high number of leaking of heat. The dark points that show on the thermal image, demonstrate the difference of material (previous point).
