Applications of Thermal Visual Measurements in Light of Toughened Up Legislation

Abstract

The purpose of research was to verify the impact of thermal modernization of existing buildings on their energy performance in light of toughened up legislation. The paper answers the question - how thermo-modernization can affect the reduction of its needs for the building and contribute to the reduction of dust emitted, when heating is based on solid fuels. Some houses of similar typical construction which was very popular in Poland in 70’, were tested. In one of them, doors and windows were replaced, but its elevation was left without insulation, while in another one, the thermal insulation was made, but old wooden door and window framing has been left. The research carried out with the thermovision camera allows a qualitative estimation of heat leakage from buildings. The test results were developed in detail in the Flir Tools software and the value of the building’s heat demand was estimated before and after the thermomodernization of the building or replacement of framing. On the basis of the conducted research, it is justified that even very high quality framing not accompanied by the insulation of the building, is definitely insufficient to meet the requirements. Only a comprehensive approach to the thermo-modernization of any building can get the desired results. In article, solutions were chosen to meet the requirements of the DIRECTIVE 2010/31/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 19 May 2010 on the energy performance of buildings.
