They allow, together with the infrared tests, to verify all undesirable system joint leaks, which significantly increase the heating energy needs. In the article the results of airtightness measurements of two flats, built in system W-70, were presented. One of the buildings is after thermal modernization. During the leakage tests the system joints were monitored with the infrared camera. Thermograms, presented in the paper, confirmed the assumption about the negative influence of joints on the total building airtightness. Described tests are a pilot studies of the problem and provide the starting point to the further measurements on the statistical level.

https://doi.org/10.4467/2353737XCT.14.257.3345It is commonly known that the thermal modernization of existing buildings reduces the energy requirements for heating. In the last twenty years many large panel blocks of flats built in the sixties and seventies have been insulated. In one example of an 11-storey building the heating energy demand before and after thermal modernization was analyzed. The transmission heat losses before and after thermal modernization, including the thermal bridges simulated in AnTherm program, were included in the calculations.
