For this thesis paper, I have undertaken the renovation of old buildings from 1932. The main problem which I have concentrated on is the dampness of walls and their repair. The aims were to preserve the original appearance of the buildings and improve living conditions inside them. Mould appeared in particular areas and using different measurements, I have tried to find its source. Using a lazar heat detector, I recorded the walls' surface temperature and how it oscillated at different points. At the same time, I also took measurements with a multi- unction detector, which consists of 4 functions in one aparatus. With this I recorded the relativity of moisture and the air temperature in the area. The collected data were put together with the air temperature readings and comparative moisture in the air, using the ARSO website, based on the TEDI calculation programme. With this programme, I have examined the corresponding constructional complex to see if from the selected data diffusion dampness is shown in any of the layers from the construction unit. Then when I had defined the problem, I began a constructional complex reconstruction in accordance with the PURES requirements, but from the point of view of the corresponding predicted heat factor U. Also assisting me were the technical building guidelines, the regulations concerning the efficient use of energy, the regulations governing the ventilation of buildings and air- conditioning, as well as the guidelines of directive EPBD-r.
I propose a suitable solution plan and constructional complex, which have arisen from the measurements' data, virtual condition of the building and their corresponding arguments.
