Measuring and regulation of computer controlled solar systems: Vizualization of energetic systems
Vlčnovská Kotlíková, Silvie ; Mašek, Ivan (referee) ; Půčková, Helena (advisor)
This work is oriented on study and evaluation of performance of real operating solar system. There was made analysis of actual technological unit and there was suggested mode of measuring of nodal parameters. There was made interconnection between the head operating unit of the solar system and the web server. And there was prepared software for grafical image of time and temperature dependence and for data transfer to ready web application. It primarily talks about increase of efficiency of real technological unit through regulating of parameter that is using up of accumulated energy.

Effect of building construction on thermal load of space
Výravská, Zdeňka ; Ell, Jiří (referee) ; Tesař, Zdeněk (referee) ; Rubina, Aleš (advisor)
This master’s thesis focuses on effect of outer building construction on thermal load of space. The effect of translucent and non-translucent construction is discussed. The project of air-conditioning system is prepared for the two alternatives of the translucent construction, including the purchase price of the airconditioning system and glazing and the savings on summer cooling. Afterwards the period of the recovery of investment is calculated. The plan of the airconditioning system is connected to my bachelor’s thesis “Airconditioning in the car showroom”, the subject of which was the plan of the airconditioning system of the car showroom.

Analysis of the thermal resistance of insulation systems from foamed insulants in flat roofs
Rundt, Lukáš ; Žák,, Antonín (referee) ; Žižková, Nikol (advisor)
On many structures there ocurred a problem of expanded polystyrene-based thermal insulation material degradation caused by high temperatures close to glazed areas. In a theoretical part of this Master’s Thesis there are the most common thermal insulation materials described, followed by a brief desciption of flat roof waterproofing materials and a thermal stress of structures. An experimental part describes a design of a methodology for evaluation of thermal resistance properties of foamed insulants in flat roofs and several experiments carried out according to the methodology.

Solar radiation in place BUT FME Brno
Horváth, Josef ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
This thesis deals with the elaboration of measured solar radiation data collected from sensors placed on C3 building - BUT FSI localization in Brno. Data measured during 2007-08 and 2008-09. The aim of this thesis is to present the measured solar radiation data in statistical and graphical form, which can be used as a basis for the solar collectors and barrier-layer calculations. Part of the thesis creates also a comparison of incident solar radiation on a horizontal and sloping surface. We will encounter here with brief characteristics of solar radiation, possibilities of utilization and the ways of its measurement.

Analysis of humid air transport in the building envelope
Tománek, Jan ; Kupsa, Tomáš (referee) ; Žák, Antonín (advisor)
The diploma thesis deals with the analysis of temperature and humidity in the construction of flat roofs with influence even without influence of solar radiation. It was necessary to study and verify the properties of building materials, the physical nature of the influence of solar radiation on building structures and the transport mechanisms of moisture. The theoretical part describes the basic physical theory on solved problems, the essence and division of solar radiation, the description of thermal moisture properties of building materials and the calculation method of determination of moisture in structures according to valid standards. Practical part deals with description of work in software DEKSOFT - Thermal technology 1D and WUFI 2D software, description of individual models and analysis of achieved results. At the end of the practical part the achieved theoretical knowledge is validated by analyzing the obtained data from the practical model.

Simultaneous utilizing of a heat pump and solar panels in a heating syste
Gongol, Jakub ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
My bachelor thesis focuses on simultaneous utilizing of a heat pump and a solar thermal collectors. I introduce principle and types of heat pumps and thermal collectors. I also introduce different sources of low-potential heat, which can be used for a heat pump. In conclusion, heat pump and solar collectors are chosen for a type house. I calculate costs needed for heating house without and with heat pump. These costs are compared and economic return is evaluated.
