Aircondition of schools gym
Sotolář, Lukáš ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The thesis is devided to three parts. The first part is the theoretical part. The theoreti-cal part deals with the heat load of buildings, which also include buildings with a ge-neral location. The second part is the computational part. The computational part is focused on heating, ventilating and air conditioning (HVAC) of the gym. The last part of the thesis is the design part.

Measurements of selected parameters of the building services systems and indoor environment of buildings
Malach, Tomáš ; Rubinová, Olga (referee) ; Hirš, Jiří (advisor)
In the first part, the bachelor thesis deals with indoor environment of buildings, solar irradiance and thermography. The measuring device for measuring the energy flows of the building, climatic data and microclimate variables are presented in this part. In the next part, I mention the principles for the measurement thermal imaging camera and I evaluate thermal images. I specify measurement of the hygrothermal microclimate, carbon dioxide concentration and climate data for power engineering. Analysis of measurement of the selected parameters is performed simultaneously and their graphical processing. In the last part, I apply measurement on the real objects, I analyzes the measured data (air temperature, relative humidity and the concentration of carbon dioxide in the room) and I perform their evaluation. At the end, I evaluate the outdoor air temperature and theirs effect for design heating and cooling systems.

Possibility of using alternative sources of energy in manufacturing facility
Malchar, Jakub ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The Master’s Thesis prospects the suitability of installing a photovoltaic system and a cogeneration unit in the LIPOELASTIC manufacturing facility and proposes their actual realization. Theoretical part describes said facility, its current energy supply situation and presents the proposed realizations' principle of operation. Practical part contains concrete calculations needed for realizations' proposal and their economic evaluation both independently and jointly.

Accumulation of Energy from Renewable Energy Sources
Heller, Ondřej ; Radil, Lukáš (referee) ; Mastný, Petr (advisor)
The objective of the first part of master’s thesis is mapping the potential of various types of renewable sources in Europe and Czech Republic, especially solar energy, wind energy, water energy and biomass. There are described principals and ways of energy generation from these sources, brief overview of current technologies, and also their advantages and limitations. An important part is electric supply continuity from renewable sources, there are large differences and the resulting to restrictions on construction and connecting the units to the power system. In this work there are mentioned some impacts on network and rates of change of supply, some sources are also evaluated in terms of maximum power, that can be connected to the power system in our country. The conclusion of the first part is dedicated to energy storage technologies, which are suitable and usable for renewable sources, there are described their principals, properties, status of development and types of aplications, in which these technologies are used. This chapter also focusses on the price level of each technology. The second part of the thesis deals with 1 MWp on-grid photovoltaic power plant design. This design includes also the redox flow batteries accumulation, the first variant calculates on 24-hour steady energy supply, the second optimalized variant calculates on daily energy supply. There are the accumulation system costs estimated and also the payback period for the both variants. Additionally there is also determined minimum penalization for cost-effective operation. The last part is dedicated to changes of impact on the local grid and changes of system impacts, after the accumulation system is installed.

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.

Modeling of solar irradiance for lunar base locations
Čašek, Jakub ; Brůha, Lukáš (advisor) ; Kolář, Jan (referee)
Modeling of solar irradiance for lunar base locations Abstract An incident radiation is an essential factor for a discovery of a place suitable for building a lunar base. This thesis presents a new approach for modeling of solar irradiance in an arbitrary lunar location at selected time. Shadowing by surrounding terrain is calculated by spatial intersection between lines of illumination and digital terrain model. Model also takes variable distance between Moon and Sun and areal representation of the Sun into account. In this thesis a new geometrical procedure for calculation of reflected irradiance is designed. The resulting model is implemented within ArcGIS software as an executable script, which utilizes the freely available data from Lunar Reconnaissance Orbiter as an input. Key words: Moon, solar irradiance, geoinformatic modelling, scripting
