The efficiency of heat distribution
Vích, Pavel ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
This diploma thesis focuses on the analysis of heat loss of heating distribution in the industrial area. The aim of this labor is to determine heat loss heat distribution kept in non manholed canal and evaluate economic return to build a local source of heat for the office building. For this building is in two variants resolve the reconstruction of the existing heating system. For the first variant is designed the local gas condensing boiler and for second variant existing central heat source. The experimental part of this labor compares the measured and calculated values of boundary conditions of hot-water pipes kept in non manholed canal.

Environmentally advanced pension
Kovář, Martin ; Blasinski, Petr (referee) ; Horák, Petr (advisor)
The diploma thesis deals with the design of a new building of an environmental metal boarding house for the elderly with almost zero energy consumption. The guest house is a free-standing building with four floors and a middle tube, which is five floors. The first floor is more accessible to the public, there is a cafe, a social hall, offices, but also a nurse's office or technical facilities. The second to fourth floors are used for housing seniors in separate housing units. The total number of seniors who can stay here is 60. The first part of the documentation deals with the building permit for the construction in question. The entire object is made of a masonry ceramic system, which are horizontally interspersed with a monolithic ceiling slab. The facade on the first floor consists of wooden paneling, on the 2nd floor to the 4th floor there is already a facade plastered with silicone plaster. The roof structure consists of two different types, namely a walkable extensive green roof and an operational one with a roof rack. The second part of the work is focused on the engineering of the building environment, where concepts for the building's water supply were created. Furthermore, the concept of loading rainwater was solved, which is solved by a system of accumulation in a concrete sump with an overflow into a soaking device. The use of rainwater for irrigation or flushing is considered here. Heat pumps (ground / water) were chosen as a source of heating and cooling, which provide us with heat in the winter and cold in the summer. DHW is solved as an indirect heating tank, which is heated by the already mentioned heat pumps. In order for the object to meet all the requirements of today's building, we had to install forced ventilation or cooling of individual rooms for ideal thermal comfort in the summer. The concept of photovoltaic panels and the design of suitable lighting in individual rooms were also dealt with in the given part. The last part of the thesis dealt with the assessment of the source of heat and cold with regard to the consumed energy, acquisition and operating costs. The result of the given energy assessment should be the selection of a suitable source for the building in question. Sowtfare used in the work: Autocad 21, Archicad 25, Lumion, Altrea Duplex, AeroCAD, Deksoft, Microsoft Word, Microsoft Excel

Climbing Centre Vertikal in Brno
Maršálková, Martina ; Kolářová, Eva (referee) ; Kolář, Radim (advisor)
The aim of this thesis is to design a climbing hall with nearly zero energy consumption located on a small brownfield at Brno-Královo pole. The thesis has three parts: The first part presents architectural and structural designs at the level of concept documentation for building permit application. It is a four-storey building with a rectangular plan, flat green roof and a external wall made of stainless steel sandwich panels. The internal space is divided into a climbing area, technical facilities, changing rooms and wellness area. The structural system is a precast reinforced concrete frame with a roof structure made of BSH solid wall trusses. In the second part the design of the technical systems of the building is presented. Ventilation and cooling of the building is provided by three ventilation units. Heating is provided by floor heating and radiators. The heat is supplied from a local district heating grid via a heat exchanger. In the third part, CFD simulations were applied to design and assess natural and forced ventilation in terms of thermal comfort, air change effectiveness, and age of air. Within the ventilation analysis, it was demonstrated that mechanical ventilation brings significant advantages in terms of thermal comfort, air quality, and air change effectiveness compared to natural ventilation. The project documentation was prepared in AutoCad software. Simulation and analysis of natural and forced ventilation was performed in CFD software DesignBuilder.
