: The article discusses the impact of the size of the shading caused by natural obstacles as the depth of the frame on the heat balance of the room, thus the selection and size of air conditioning equipment. Taking into account this phenomenon on the design stage, we are able to avoid wrong device selection, and thus reduce cost of whole installation. A thorough analysis of the affection of shading in passive construction through the use of shading elements, is an opportunity to reduce the flow of solar energy in the summer and thereby improve the energy consumption of the building.

The application and utilization of the industrial wastes and by-products in the construction industry is a key issue from an environmental and economic point of view. The increased use of lignite has substantially increased the available quantities of lignite fired power plant fly ash, which can be main- ly classified as class C fly ash. The utilization of such raw material however has some difficulties. In the present paper lignite fired power station fly ash and metallurgical converter slag were used for the pro- duction of geopolymer concrete. The fly ash was used as a geopolymer based binder material, and a con- verter slag as aggregate, thus created a geopolymer concrete which contains mainly industrial wastes. As preliminary test experimental series were carried out using andesite as aggregate. The optimal aggre- gate/binder ratio was determined. The effect of the amount of alkaline activator solution in the binder, the aggregate type on the geopolymer concretes' compressive strength and density was investigated. Fur- thermore, the physical properties - freeze-thaw resistance and particle size distribution - of the applied aggregates were measured as well. As a result of the experiments it was found that physical properties of the andesite and converter slag aggregate was close. Therefore andesite can be replaced by converter slag in the concrete mixture. Additionally, geopolymer concrete with nearly 20 MPa compressive strength was produced from class C fly ash and converter slag.

The paper provides information on the history of the creation and activities of the Geodynamic Laboratory in Ksiąz (Central Sudetes, SW Poland). A unique laboratory environment, instrumental facili- ties and research program were presented. Particular attention was paid to the study of geodynamic sig- nals of non-tidal nature, relating to the local geological and tectonic situation. Tectonic research is exam- ined in terms of both cognitive (identification of causes of the occurrence and scale of the problem), as well as utilitarian aspect designed to assess the impact of recorded effects on the earth's surface and archi- tectural objects
