Social HUB in Havlíčkův Brod
Jiráček, David ; Müllerová, Eva (referee) ; Kalousek, Lubor (advisor)
The subject of the Master’s thesis is a design of a social center in Havlíčkův Brod. The building will be primarily used for social meetings, education, sports activities or relaxation. It is a two-story building, where both floors are covered with an extensive green walkable flat roof. On the first floor are a café, a multi hall, a chill zone, a workshop for children, dressing rooms, a workshop for adults and utility room. On the second floor are club-room, two classrooms and an office with a room and a walkable terrace. The vertical load-bearing structures are made of CLT panels with a combination of timber and steel columns and beams. The floor structure is made of wooden I-beams and CLT panels. The entire building will be heated by a ground-water heat pumpy. The air handling unit will primarily serve as ventilation. Rainwater will be collected in a storage tank and subsequently used to flush toilets and irrigate the adjacent public space. The photovoltaic system will partially cover the building’s electricity consumption. The third part of the thesis deals with facility management of the building. It contains description of the functioning of the building management and determination and use of important data from the digital model of the building for the facility management. Digital model was created in the Archicad program, where I entered specified data and than I presented then by using the tables.

Economics and viability of photovoltaic power station
Mrázek, Dalibor ; Bača, Petr (referee) ; Křivík, Petr (advisor)
At the beginning of the submitted work, I dealt with the study of various types of photovoltaic panels, their diverse use, effectiveness, advantages of each type and description of climate in the Czech Republic. Depending on the number of sunny days and no claudy days, I was looking for the best areas photovoltaic power. On the basis of cooperation with the firm and Energ-servis and using their test center, I compare different types of panels, their performance in relation with the cost and method of purchase. From these data, six diverse installation, I tried to determine the best type of panel that is best for the South Moravian region in the cost / return on investment.

Integration of Photovoltaic Power Plants in the Electricity System
Michl, Pavel ; Paar, Martin (referee) ; Mastný, Petr (advisor)
The thesis discuses an integration of photovoltaic power stations to electric network. The first part describes connecting conditions of small sources to distribution system, including administrative requirements, feasibility study, and requirements to the energy meters, measuring, control devices, switching devices and protection. The second part is aimed to describe problems of the photovoltaic system. Solar radiation generating and reducing of its intensity incident upon the earth surface are described in this part. The quantum of produced electric power depends on climatic conditions in the fixed area, seasons, etc. This work also discusses the types of photovoltaic cells and their actual efficiency. Inverters are further important components of the photovoltaic system. The parameters of the inverters have a great influence on the total actual efficiency of the photovoltaic system. Different methods of the photovoltaic panels’ connection with the inverters and their advantages and disadvantages are also mentioned. The supporting structure of the photovoltaic panels and eventually transformer are further important components of photovoltaic system. The work also analyze the methods of connection of the photovoltaic power station to distributive low voltage and medium voltage network, electric energy accumulation and possibilities of the sale of produced electric energy. The large number of the connected photovoltaic power stations has negative influences to electric network. The third part contains the design of a photovoltaic power plant with a capacity of 516,24 kWp on the scoped area in southern Bohemia. The project documentation for the location where the power plant is designed is also made. It contains the design of photovoltaic panels, the design of the inverters to get an optimal power load. This part also contains a calculation of the photovoltaic system losses and the design of transformer and the cable junction calculation of the distributive system. The feasibility study of the power plant connected to distributive system is also conducted. Its delivery rate will be connected to the distribution point Řípov (110/22 kV). The calculation results show us that this photovoltaic power plant can be linked to the distribution system. The final part of this paper contains an economic estimate of the photovoltaic power plant operating and the calculation of the return. An Economic return is influenced by the wide range of values that affect the total return rate. The calculation of an operating economy is made for several variants. The return rate in refer to contemporary redemption price for 2010 with no consideration for a bank loan is 7 years. If we consider the bank loan it would be 12 years. The penetrative reduction of the redemption price is expected for 2011. Calculation works with the decline of 30 %. It would extend the rate of return to 11 years without a bank loan or to 22 years with the bank loan. The bank loan is considered to cover 80 % of the investment.

Renovation of a family house
Červinka, Michal ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
This master’s thesis is dealing with the plan of reconstruction of the house in an effort to get closer to "near zero building". Total heat loss along with calculation of the cost of the house operation and the energy performance of buildings were computed for the given house. Then we have enclosed suggestions of individual methods of building´s insulation (replacing of windows, doors and gates, insulation of exterior walls, roof and ceiling between floor and attic) and a draft of a new technical building services (forced ventilation with heat recovery, photovoltaic system and heat pump). Furthermore, the suitability of the original heating system was evaluated and the also the energy performance for the renovated building was analyzed during the reconstruction. An economic evaluation was calculated for each method of reconstruction, together with the new green subsidy programme. At the end of the dissertation is drawn up the economic evaluation of the whole proposed reconstruction, together with an assessment, what class of the building we have achieved according to its the energy intensity.
