Realistic Rendering of a Building with Varying Lighting Conditions
Navrátil, Jan ; Seeman, Michal (referee) ; Herout, Adam (advisor)
This paper is focused on realistic rendering of interior environments with varying lighting conditions. It proposes methods of setting properties of light sources to achieve a specific scene appearence. It mainly works with light comming from a sky and sun to the scene and describes this light in relation to weather conditions, time of day and overcast factor. The goal is creating easily configurable system in which a single parameter change leads to significant change of lighting conditions. All these changes should be presented in a short video.

Climate testing room for personal vehicles
Málek, Ludvík ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
The diploma thesis deals with the design of testing equipment, a climate chamber in particular, to simulate external weather conditions. The chamber walls are made of socalled sandwich insulation panels. Based on the wall thermal properties, heat loss of the chamber was calculated. The conditioned air is supplied by a distribution channel at sides of the chamber. The exhaust air leaves the chamber in the ceiling zone. The ventilation unit is located on the ceiling. The design includes the integration of the UV lamp, simulating sunlight. The chamber will allow the weather effects on the microclimate inside a car to be studied. Furthermore, the sunlight simulations can be carried out in the chamber to detect polymers or varnish aging, and the fading of colours.

Comparison of the effectivity and the ecological benefits of photovoltaic power stations in different areas of the Czech Republic
SLUKA, Petr
The study is focusing on comparison of efficiency and ecological impacts of photovoltaic power stations depending on their locations in the Czech Republic. The report gives us an overview of photovoltaic power stations efficiency and also their environmental value by minimising CO2 emissions due to replacing conventional energy technologies. The research is based on data taken from energy audits of photovoltaic power stations in Vidov (South Bohemia), in Hodonice (South Moravia) and Lahošť (North Bohemia). The measured data of efficiency and CO2 savings are compared to forecast data from numerical weather prediction models PVSYST, PVGIS and Meteonorm. The project revealed, that photovoltaic power stations efficiency directly depends on their geographic location. Decisive factor was sunlight. Paired comparison showed, that there is a difference between photovoltaic power stations in Lahošť, Hodonice (P < 0,01) and Vidov (P < 0,05). The difference between real and expected datas from each photovoltaic systems was conclusive (p < 0,01). Significant was also factor of month (p < 0,001).
