A space heating system for a three-story row hose
Aulehla, Jiří ; Pokorný, Jan (referee) ; Charvát, Pavel (advisor)
This master`s thesis describes the design alterations that lead to a reduction in heat loss of the house, an extension of living space in the attic and the subsequent reconstruction of the heating system. The first is presentation of the house. After that, there is calculation heat loss of the house. The next step contains design of a reconstruction for every room and calculation modified heat loss. Another point this work is design the reconstruction of the heating system, extension heating system to the attic floor, calculation pressure losses and selection condensing gas boiler. After that is designed regulation with central control unit and electric thermostatic radiator valve. The last part of master`s thesis is focused on benefit assessment changes, budget and return of investment. The drawings are listed in the appendix.

Heating of the Manufacturing Hall with the administration
Březina, Jan ; Formánek, Marian (referee) ; Vendlová, Lucie (advisor)
The purpose of this bachelor thesis is to compare different heating systems for industrial buildings and to find suitable solution for the heating system of the manufacturing building located on Brno periphery. The manufacturing area consists of two one-floor manufacturing halls and three-floors administrative building. The building heating is ensured conventionally, forced ventilation is only in manufacturing halls. The heat source is gas condensing boiler located together with air-conditioning unit in technical room. The heating system is designed with accent to smooth and effective functionality.

Operational efficiency of gas boilers
Marčiš, Šimon ; Vyhlídalová, Karolína (referee) ; Počinková, Marcela (advisor)
This master’s thesis elaborates a design of water heating and heating system for a building of a rehabilitation center in Horný Hričov. The theoretical section describes operational efficiency of gas boilers and associated calculation methods. The experimental section covers measurements of condensing gas boiler at various temperatures of heating water conducted in university laboratory. Operational efficiency was then calculated using indirect method based on the measurement results. Subsequently, calculated values and values measured by an operational efficiency analyzer were compared. The comparison revealed minor deviations in operational efficiency values and different values of condensing heat utilization between the calculations and the analyzer results. The analytical section of the thesis consists of complex designs of two versions of the heating system and the water heating. The first design version uses condensing gas boilers as a heat source while the second version uses a water-air heat pump instead. The project section of the thesis is executed in the scope for a building permit and consists of a technical report and a design documentation.

Civic amenities building
Gyepesová, Angelika ; Svoboda, David (referee) ; Berková, Petra (advisor)
The aim of the diploma thesis is the design of sports centre with nearly zero energy consumption. The thesis is consist of three parts. First part is focused on architectural and structural design. Second part is focused on building services designs. Third part is focused on acoustic assessment of the building. The building is located in Šternberk on a sloping terrain. It has two floors, irregular floorplan and flat roof. The capacity of the building is 104 people. In the building there are rooms for table tennis, spinning, TRX and a gym. There are also massage rooms and a sauna. The building includes a buffet with refreshment and a shop with nutritional supplements. The structural system of building is combined. The structural framework consists of prefabricated columns and beams. The internal and external load-bearing walls are designed from lime-sand blocks and the partition walls are from aerated concrete. The floor and roof structures are designed of prestressed concrete. Heating in the building and the water heating is secured by two ground source heat pump and a stationary condensing gas boiler. Ventilation is provided by air-handling units with heat recovery. Cooling is secured by one of the heat pumps. Electricity consumption is partially covered by photovoltaic panels on the roof. The building has incorporated rainwater storage tank for watering greenery. The third part of this diploma thesis deals with room acoustics and the closely related issue of reverberation. Part of the work is a drafting of acoustic modifications of the sports rooms based on manual calculation. The project aims to improve the acoustic properties of the premises by incorporating elements that have sufficient sound absorption. These are perforated false ceilings, acoustic wooden cladding with different perforations and green walls.

Civic amenities building
Svoboda, David ; Pilný, Ondřej (referee) ; Berková, Petra (advisor)
The aim of the master’s thesis is the design of a new music club building in Valtice. The first part of the thesis is the architectural and structural design. The building of irregular rectangular shape with one underground floor and two above-ground floors is divided into two main operational units – a dance hall and a rock club. The chosen structural system is reinforced concrete columns with locally supported floors. The walls are made of sand-lime blocks. The main insulation material is hemp. The building is covered by a flat roof with extensive greenery. The second part deals with the building services. Ventilation, heating and cooling are provided by HVAC units. The heat source is condensing gas boilers, the cooling source is an outdoor VRV cooling unit. The third part of the master‘s thesis is the acoustic assessment of the building. As a noise source, it mainly addresses the acoustic impact on the surrounding buildings in the vicinity. Furthermore, it optimizes the reverberation time in the rock club. The project was produced in accordance with the legal regulations and technical standards and created in AutoCAD software.

Heating and cooling systems
Pavlíček, Radek ; Vyhlídalová, Karolína (referee) ; Počinková, Marcela (advisor)
The topic of this diploma thesis is large area heating and cooling systems. Theoretical part of this thesis is focused on thermal comfort of people in interier and on theoretical calculation of heat transfer and on large area heating and cooling systems. Second part is devided to two variants. First variant is design of a heating system in kindergarden with floor heating combined with plate heating radiators. Second variant is heating system with only plate heating radiators. As source of heat is used condensing gas boiler. Part of a design is preparation of hot water. Experimental part of the thesis contains measurements of coefficient of heat transfer in floor heating and wall heating.
