Object of civic amenities
Zachovalová, Jana ; Pilný, Ondřej (referee) ; Berková, Petra (advisor)
Submitted diploma thesis prepares project documentation for the construction of a hotel building with a restaurant, which is located in the central built-up area of the town called Letovice situated in the South Moravian region. The solved building is partially basement with three above-ground floors covered by a flat vegetation roof. The hotel is designed with 23 accommodation units with a total capacity for 52 persons (including 4 persons with reduced mobility on the 2nd floor) and a restaurant for 98 guests, a bathroom and a kitchen. Guest rooms are located in the 2nd and 3rd floors. There are representative areas of the hotel in the form of an entrance hall with reception, areas for hotel management and a restaurant with a kitchen including social facilities for employees on the groud floor. There is a technical background of the building and maintance working room in the basement. The building comlies the requirement for low-energy standard buildings by combining a quality construction solution with thermal insulation of the building cover and other technological solitions. The overall character of the building is underlined by its architectural design in the form of partial greening of the facade. This solution is combined with large glazed areas giving a feeling of spaciousness and evocative cleanliness to the building.

Household heating systems
Ševčík, Ondřej ; Bok, Jaromír (referee) ; Bartošík, Tomáš (advisor)
Main goals of this bachelor thesis are economic evaluation of four chosen technologies of heating, and heating system design. Introduction deals with problem of heating in a family house, types of heating systems and main influences affecting the choice of heating system. The third chapter discusses main components of heating systems. Each component of the system is characterized and described. The most important parts include heating source, which are divided by type of fuel. The fourth chapter describes other possibilities of austerity meassures, which reduce heat loss and heating costs. There is a mention about government subsidies. The fifth chapter shows the shares of different heating sources, that are used in residential houses. In the last chapter, the computation of heat loss in the particular object is done. Based on the heat loss computation floor and radiator heating system is proposed. Four heat sources are chosen for the object (gas boiler, heat pump, biomass boiler and electric boiler with acumulation tank) and the purchase and the operating costs are computed. Conclusion of the chapter is devoted to the economic balance of the four heat sources and their comparison in the return of investment.

Optimation and Innovation of Heating by Thermal Pumps
Petr, Jan ; Kudela, Libor (referee) ; Lisý, Martin (advisor)
The Bachelor’s Thesis adresses heat pumps, its description, comparison and assessment of heating of the model house. In the first part the research is done. The research describes on what principles the heat pump works and how they differ. In the second part, the model house is described. Heat losses are calculated. For two types of heat pumps are calculated returns on investments.

Heating of the kindergarten
Černý, Tomáš ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The bachelor thesis solves the design of the nursery heating. The theoretical part deals with the topic of floor heating. The calculation part contains the design of heating the building using hot-water underfloor heating. Further solves the calculation of hot water exchanger for forced ventilation of selected rooms. The air-water heat pump is designed as the heat source. Part of the calculations is also the preparation of hot water and all the necesary equipment of the system. Kindergarten is designed as a nearly zero-energy building.

Energy efficient building systems
Hakl, Jaroslav ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
Content of this diploma thesis is analysis of the operation of heat and cold sources and its evaluation based on data from measurement and control systém and design of a new solution for heating and cooling selected part of the object Otevřená zahrada. Building is located on the street Údolní in Brno. It is a three-storey building serving as offices of non-profit organizations and weekend activities of the organization. On the first floor there is a technical background of the building and half of it is used by four offices. On the second floor there is a seminar hall with a capacity of 50 persons. The rest of the floor is used by three meeting rooms and three offices. The third floor is used by four offices. For the heating and cooling of building, there are designed heat pumps ground-water. Air exchange in the building is provided by the air handling unit.

Comparative study of PV and heat pump in domestic energy supply
Kiša, Michal ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This thesis focuses on the utilization of a heat pump and photovoltaic system on specific residential house. It clarifies the basic concepts of the heat pumps, photovoltaics and their application on a house. In the description of the house there are mentioned basic parameters, a description of the existing system. There are heat demands calculations for house heating and water heating, calculated according to the theoretical values and these are compared with the actual values. The practical part deals with the design of heat pump and photovoltaic system. Also there are assesses of the purchase prices, the operational costs and the following investment returnability in comparison with a fireplace insert with accumulation storage and an integrated electrical heating element.

Heat pump performance data analysis
Šeda, Libor ; Krejčí, Vladimír (referee) ; Hejčík, Jiří (advisor)
V bakalářské práci jsou shrnuty dostupné metody a koeficienty užívané k testování výkonu a ekologické náročnosti tepelných čerpadel. Pro testování dle norem ISO jsou zde také vysvětleny vstupující faktory. V praktické části je vyhodnocen běh reálného tepelného čerpadla z hlediska výkonnostních parametrů a parametrů týkajících se běhu kompresoru, jako je počet pracovních hodin nebo počet odmrazení.

New station of the Czech Mountain Rescue Service in Ramzová made of hempcrete
Harazin, Tomáš ; Pilný, Ondřej (referee) ; Kalousek, Lubor (advisor)
The aim of this project is a design of a Mountain Service station in Ramzová located in the Protected Landscape Area Jeseníky. It is a two-storey rectangular building with a gable roof. It has a light wooden frame with hempcrete thermal insulation with diffusely-open constructions. The roof and the facade are covered with split larch shingles. All materials used are selected with respect to their environmental impact in combination with modern approaches. The building is designed as a near-zero energy building, including an air handling unit, a heat source in the form of an air-water heat pump, as well as photovoltaic panels placed vertically on the structure in the northwestern part of the property. The work also includes research into the properties of hempcrete. Laboratory measurements of a heat transfer coefficient and compressive strength of the material were made on samples of hempcrete and are implemented to the project. The result is a building using today's most advanced technology combined with traditional natural construction.
