Environmental solution of a house with a café in Zaječí
Medková, Tereza ; Uher, Pavel (referee) ; Rubina, Aleš (advisor)
In my master's project I design a nearly zero energy consumption house with a café in Zaječí. The 1ST part of this project deals with a structural part of the building, which has two above-ground floors and basement. On the basement are storerooms and rooms for technical equipment, on the ground floor is café and living room with kitchen, and on the second floor are bedrooms, bathrooms and cloakrooms. Footings are from cast-in-place concrete, the load bearing walls on basement are from formwork blocks with cast-in-place concrete, on above-ground floors are from ceramic blocks and every non-load bearing walls are also from ceramic blocks. On whole floor are reinforced concrete floor slab and flat green roof. The 2ND part deals with technical equipment of the building. There are gas boiler, floor heating, air conditioning, mechanical ventilation (HVAC), photovoltaics panels with energy storage, retention tank, external blinds and biodynamic lighting. The 3RD part compares several options for using solar energy in combination with different heat sources in terms of energy and economic efficiency of the building.

Heating system of a Low-energy house
Jankola, Mario ; Pech, Ondřej (referee) ; Katolický, Jaroslav (advisor)
This master’s thesis pertains to heating practices of low-energy houses using a heat pump (example 1) and low-temperature condensing boiler (example 2). The first part of the work contains calculations of suggested building’s heat efficiency and of under-floor heating. The second part of the work includes estimates of seasonal heating factors for construction with a heat pump. Based on the comparison: both of these heating systems are recommended; the capacity of the warm water container is established; and safety elements are chosen. Furthermore, a system of regulation for warm water heating is determined, and a curve of equithermal regulation for heating is calculated. Both of the recommended heating possibilities include calculations of costs of supplies and manufacturing, as well as blueprints for construction.

Optimizing The Design of Dry Floors
Hlavsa, Petr ; Chybík,, Josef (referee) ; Klečka,, Tomáš (referee) ; Tuza, Karel (advisor)
This dissertation deals with the optimization of the dry floor design by solving the innovative floor composition supported by the development of a new floor element, doing so from the point of view of building physics – especially the heat and mass transfer in buildings – with the consideration for the benefits for acoustics. It is aimed at dry floors application to modern timber structure. In the area of heat and mass transfer in buildings, the impact of thermal stability of rooms and its increase in the use of a new floor structure is investigated with the inclusion of a proposed element improving the thermal storage capacity of the floor. All this in the context of ensuring the possible floor heating integration. In the evaluation of thermal stability in rooms, those operating conditions that are accompanied by interrupted heating, are considered to be key. After describing the current state of solving this issue, the main focus of this dissertation is its own development and design of a specific floor element and its integration into the floor composition. An important part of the dissertation consists of related numerical simulations, its own experiment, relevant measurements in the experimental object, and their evaluation.

Heating of the kindergarten
Jetelina, Michal ; Wierzbická, Helena (referee) ; Počinková, Marcela (advisor)
This work is solving the proposal of heating a kindergarten. The theoretical part is focused on warm water heating, which is used in the proposal. The computational part includes a proposal of heating the building. The system is a combination of low temperature system and underfloor heating. As a warm source, there is a design of thermal pump of air and water, which is located in exterior. The ventilation of the building is natural or forced, depending on location. The work contains proposal of all needed equipment and also the design of the source of warm water.

Heating of the exhibition rooms
Ženíšek, Pavel ; Vendlová, Lucie (referee) ; Vendlová, Lucie (referee) ; Počinková, Marcela (advisor)
The bachelor thesis delas with the heating of the exhibition rooms and preparation of the warm water. The building will be heated by plate radiators, convectors and underfloor heating. As a heat source is used a heat pump. Warm water is prepared in the DHW cylinder, heated by the heating water from the heat source. The project deals with the desig,n dimensioning and connection of these parts. The thesis also includes a theoretical part on the topic of underfloor heating.

Low temperature heating with heat pumps
Bros, Miroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The master’s thesis deals with design and comparison of two variants of low temperature heating with radiant systems and heat pumps. Building is used for administrative purposes. The theoretical part describes the evaluation of heat pumps. The calculation part deals with the calculation of heat loss of the building, the design of the heating system, the hot water preparation system, the heat source, all necessary supplementary devices, and the calculation of yearly heat and fuel consumption for heating and hot water preparation of the building. Heating system consists of floor heating and ceiling heating. For hot water preparation an indirect fired hot water storage tank is designed. The source of heat is a cascade of two air/water heat pumps. Experimental part is focused on measuring and assessment of pressure loss, heat output and efficiency of radiant ceiling panel.

Housing for Seniors
Pilík, Václav ; Blažková, Vendula (referee) ; Daněk, Lukáš (advisor)
The diploma thesis is elaboration of project documentation of the object Housing for seniors in Brno - Dolní Heršpice. The site is located un the area with the planned development of the city. The object is detached, three-story with a partial basement. The building is divided into five parts. The building is based on concrete foundation pads and strips. The structural construction is a combined column and wall system in technological design as monolithic concrete. The building is designed as a low energy building, with contact insulation (ETICS). The whole building is designed with forced air exchange. An extensive and intensive walkable flat roof is designed. The aim is to create small, barrier-free, community housing with affordable services and support, with a possible life expectancy. Services for the elderly with reduced self-sufficiency and with mild health and mental dysfunctions are considered. The building is equipped with space for accommodation with a capacity of 48 beds, space for eating with a separate kitchen, space for leisure and physical activities, space for basic health and social care and space for administrative and technical facilities. The construction is divided into several buildings, the subject of the thesis is primarily the solution SO.01 - Housing for seniors

Pressure losses in heating systems
Švanda, Martin ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
This diploma thesis deals with pressure losses in heating systems. The diploma thesis is divided into three sections. The first part is theoretical and deals with the occurrence of pressure losses. It discusses the properties of the fluid that affect pressure losses. It also deals with hydrodynamic phenomena, flow distribution, pressure loss distribution and its calculations. The aim of the second part, which is practical, was to create a heating project for a selected object. The object is a two-floor kindergarten building located in Velké Němčice. For this project, two heating variants were created. For the first variant, radiators and heating benches were designed and for the second variant, underfloor heating was installed in the building. The goal was to use a source which will gain heat mainly from renewable sources, so the air / water heat pump was chosen as the source of heat production. The project ends with a technical report. The third part of the thesis is dedicated to an experiment which purpose was to find out how the pressure losses of the connecting pieces are reacting to the change with the change of the heating water conditions (flow, temperature). Alongside, two pipes were created which differed in the type of connecting pieces so it allowed to compare how their pressure losses differ. Both pipes were connected by radial pressing, but the fittings differed in the quality of the brass, and therefore in the construction. Also, part of the experimental section of the diploma thesis is a description of the course of radial pressing of fittings from the Herz company.
