Energy use of the facade
 Salajka, Radek ; Rubinová, Olga (referee) ; Rubina, Aleš (advisor)
The main motive of this master's thesis is expanding awareness of ventilated facades and their use and comparison with external thermal insulation composite system (ETICS). I mention this in theoretical research. As an expansion to theory and a key theme of this thesis is a description of individual physical events present on the facade and in it's ventilated gap based on data output from measurement. The data gathering was made by a group of professionals who have done an on-point facade measurement on a real ventilated facade throughout a year - more detail in text. I personally have been a part of a research team and I describe my work and research in detail in the third part of this master's thesis - experimental part. In practical part I devote myself to use our new knowledge on a given building. More precisely - I use numerical calculations to present energy use of of given facade in comparison with ETICS on the same building with the same boundary conditions.

Study of light microclimate in a chosen vegetation type during vegetation season
 STOLIČKOVÁ, Martina
The aim of Bachelor thesis is the analysis of light microclimate depending on the production profile of sedge vegetation ( Carex acuta L. ) during the growing season. The light transmission of the growth of sedge and its changes during the growing season were examined. Then the seasonal cycle of the incoming and reflected solar radiation, including the albedo was evaluated.The seasonal changes in increase of aboveground live biomass, the amount of dry matter in the vertical vegetation profile, the distribution of leaf covering and the extinction coefficient changes during the growing season were assessed. The study of light microclimate and the biomass sampling was conducted in Mokré Louky near Třeboň close to pond Rožmberk. The largest representation of plant species has got Slender sedge ? Carex acuta L. there. The findings of relative insolation and light transmission was measured by pyranometer and the sampling of aboveground part was conducted by destructive method. These results show that the transmission is the highest at the vegetation surface and it decreases with the declining height. In August there was a radical decrease in the impact and the reflection of solar radiation due to the higher concentracion of water in the soil and air and this led to a reduction in albedo. Live biomass was measured: in July 1820g, in August 1670g and in September 1789g.The values of LAI and dry matter, recorded from July to September,were gradually decreasing and with the growing measured layer of growth there was a reduction in amount of dry matter and value of leaf area index.The extinction coefficient value varies depending on the age of stand. With the vegetation age the extintion coefficient increased up to 200,38. The Bachelor Thesis was developed within the research project of Faculty of Agriculture MSM 6007665806 ? The sustainable methods of farming in the foothills and mountainous areas,aiming to create harmony between their production and non-production application?.
