The article presents the results of air temperature measurements inside a basement, outside it and in the ground adjacent to the building. The results and their analysis reveal that indoor thermal conditions develop differently in rooms with earth-contact structures. Intermittent heating exerts an important influence on the shaping of temperature conditions in a basement and its vicinity.

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. ...
The paper presents analysis of existing concrete tiles roofing on outbuildings in selected localities of the Pińczów district. On the basis of the observations on the spot it was established that concrete tiles constitute 18% of all roof coverings in the investigated area. It is the most frequently used on livestock housing. It was noticed that of all concrete tiles, 81% are the products manufactured using traditional methods, directly on the construction site. Water absorption by weight was determined for selected concrete tiles in order to assess the technical state of existing concrete tiles roofing. The tests of water absorption by weight revealed about 1.6% lower water absorption for tiles mass produced by industry than for traditionally manufactured ones. The tiles utilised on buildings for more than 40 years were characterised by even 0.7% increase in water absorption by weight in comparison with non-utilised tiles. ...
