Household cost analysis
Havránková, Denisa ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The diploma thesis deals with the analysis of the cost of a house in the area of peripheral constructions and the effect of thermal insulation on energy consumption for heating and hot water. The theoretical part generally defines renewable energy sources, heat sources, thermal transmissions and structural losses, basics of valuation of construction works and supplies and overview of state subsidies. In the practical part are proposed composition of peripheral constructions, calculation of heat transfer coefficient of all designed perimeter structures and their subsequent evaluation. Furthermore, there is an estimated annual energy demand for heating and hot water and annual electricity consumption in the household. At the end of diploma thesis is a proposal of suitable energy sources and calculation of the return on investment in these sources.

Wireless Sensory Network Using LoRa Technology
Mikulášek, Michal ; Pokorný, Jiří (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis focuses in the first half on the Internet of Things and the available wireless technologies for the Internet of Things. Each technology is characterized by its features, pros and cons, as well as the possibilities of using it in the Internet of Things. In the second half of the thesis, a practical design and construction of a LoRa network, consisting of a sensory and a central unit, is carried out. The parts of the solution are designed wiring schemes, printed circuit boards and detailed photo documentation. Additionaly the software solutions for both types of units are described, with detailed descriptions of the proposed features. The maximum possible range is tested and documented for the entire solution. Subsequently, a detailed measurement of the power consumption of the sensor unit is carried out and an extensive estimation of its battery life for a selected battery.

Energy assesment of single family house
Panovec, Jan ; Počinková,, Marcela (referee) ; Hirš, Jiří (advisor)
The aim of this bachelor’s thesis is to understand the nature of the energy assesment of building with low energy demand and energy-saving requirements. The calculations of energy intensity and experimental measurements of chosen parameters of inner microclimate in the building were done. Theoretical part includes requirements and principles of projecting buildings with low energy demand.

Economic and Technical Analysis of the Photovoltaic Facade System
Bónová, Kateřina ; Žák,, Antonín (referee) ; Hlavinková, Vítězslava (advisor)
This thesis comprehensively analyses photovoltaic power plants on facades both from economic and technical point of view. It also devotes to a broader view upon a photovoltaic power plants regarding their placement, its accessories and legislative. The thesis describes a calculation of energetic gains in details including evaluation of five solar radiation sources in order to assess energetic effectivity of the photovoltaic equipment. Furthermore, the thesis describes a means of determination of photovoltaic revenues which is closely related to its ability to sustain the energetic demand of the building. These calculations are presented in the conclusion of thesis where they are applied to four selected buildings. The thesis also contains a processed graph due to which it is possible to specify optimal size of photovoltaic facade. The size is depending on selected facade cardinal point orientation and also on floor area of the building, which serves to estimate future electricity consumption.

Heat pump heating for a house
Loibl, Jan ; Hrnčířová, Michaela (referee) ; Nerud, Pavel (advisor)
The theoretical part of the bachelor thesis deals with introducing to the issue of heat pump systems. The functioning principle of the most widely used heat pump type is explained here as well as its coeficient of performance, its operational modes and fundamental components. In addition, possible ways of heat pump systems application in terms of obtaining lowpotential heat are introduced. In the practical part the calculation of thermal loss of selected family house is discussed together with the calculation of heat requirements for heating and domestic hot water. The following part focuses on the selection of the most appropriate type of heat pump systems for covering heat demands of the selected house. The final part poses economical assesment of the designed heat pump system including the calculation of investment recovery.

Energy assessment of buildings
Velísková, Eva ; Maurerová, Lenka (referee) ; Hirš, Jiří (advisor)
The master’s thesis deals with energy assessment of buildings according to a current valid legislature. In the first part the energy assessments problems are solved. The next part solves the energy concept of the educational building, Pavilion P4, AdMaS centre of Faculty of Civil Engineering of BUT, in the form of project documentation. In the part of thesis there is a simulation characterizing dynamic behavior of building. The thesis point is the evaluation of energy balance and a draft of measures leading to the power consumption decrease.

Design of a heating system for an office building
Vítek, Lukáš ; Horká, Lucie (referee) ; Vyhlídalová, Karolína (advisor)
The aim of this bachelor thesis is to design a proposal of space heating and water heating system for an administrative building in Ostrava. The building has four above-ground floors and an underground floor. In the underground floor are located technical building background, stocks and a parking. In the above-ground floors are administrative offices. The heating is solved as a water heating, with a distribution of the heat into the space using panel radiators and convectors. Water heating is solved by an accumulation heater. As a heating energy source serves a cascade gas boilers. We can find in the whole building a forced ventilation. The theoretical part of this thesis deals with the BIM technology.
