Thermographic analysis of selected building partitions in the context of their thermal insulation properties

Temperature is a scalar physical quantity, one of the principal parameters determining the state of a thermodynamic system. It corresponds to the average kinetic energy of the motion and vibration of particles in the system. One of the popular methods of temperature recording is the measurement of electromagnetic (infrared, thermal) radiation parameters emitted by a body of a temperature above the absolute zero (0 K or -273.15°C). The measurement is defined as thermography and it is used to produce images of the distribution of temperatures on the surface of an object (objects) with the use of an infrared radiation detector. The main advantage of this type of measurement is its non-invasive nature. Due to the use of a thermographic camera, it is possible to detect most construction defects without interfering in the structure of a building partition. Thermography allows the measurement of temperature in the spaces that are not easily accessible or those where traditional methods are impossible to employ. Thermography is used in a variety of research specialisations. The article presents the results of research relying on the use of thermogram analysis in the estimation of thermal insulation of chosen external building partitions. Much attention was given to façade ...

The energy cost versus energy absorption of single family houses – a case study of city of Jasło

The paper presents an analysis of energy absorption and the costs of the energy for heating single family houses situated in the city of Jasło. The conducted research demonstrated a considerable diversification of material and construction solutions of the walls and the applied heating systems. Values of the heat transfer coefficient for exterior walls exceed the currently applied standards in most buildings. Heating systems are mostly hard coal fired. Warm water preparation supported by solar thermal collectors was used only in several houses. Analysis of the research results revealed a lack of correlation between the energy costs and heat transfer coefficient for the external walls. ...
