SIMULATION OF ENERGY PERFORMANCE AND REAL OPERATION OF BUILDINGS
Šteffek, Libor ; Ingeli,, Rastislav (referee) ; Hirš, Jiří (referee) ; Ostrý, Milan (advisor)
This dissertation thesis primarily focuses on the experimental measurement of energy consumption of a given energy-passive family house as well as theoretical research in the field of energy calculations using computer simulations. The results of quasi-stationary and dynamic simulations, with varying computational and real-time climate data, are compared with experimental measurements. Using the dynamic calculation model, which was validated by actually measured data, the relationship between architectural design and the energy performance of the building was analyzed. The influence of selected different operating modes for heat consumption on heating, cooling, ventilation, and interior overheating is observed. The result of the mutual interaction of several input parameters of variant solutions provides the basis for optimization of the whole design.

Kalánek, Jiří ; Ingeli,, Rastislav (referee) ; Šťastník, Stanislav (referee) ; Ostrý, Milan (advisor)
The dissertation thesis is focused on thermal insulating properties of reflective insulation under boundary conditions typical for low-energy buildings. In the introductory part of this thesis the attention is focused on the heat transfer process. There is described primarily heat transfer by radiation. There is also described the reflective insulation and the methods of determination their thermal performance. The remaining part of the thesis deals with the analysis of the results obtained in experimental measurements. Measurement results are compared with the calculation model. Conclusions for technical practice including possibilities of further research are summarized in the final section.

The aim of this master thesis is multi-criteria assessment SBToolCZ of the building district department for Czech police in Kyjov. The building has a basement with underground garages, shooting range and technical facilities (boiler room, air conditioning room, storage, archives, cleaning room), and a ground floor with offices covered by a flat roof. The load-bearing structure of the basement is designed from watertight reinforced concrete. The ground floor has ceramic block walls. The floor and roof structure are designed from pre-stressed Spiroll. The building envelope is insulated with ETICS. The thesis also contains project documentation of building and HVAC design. The project was carried out in the AutoCad programme. Project documentation was prepared according to valid legal and technical regulations.
Mathematical simulation of temperature profile in the subsoil and creation of a model corresponding its real state
Charvátová, Pavlína ; Katunský,, Dušan (referee) ; Ostrý, Milan (referee) ; Čupr, Karel (advisor)
Increasing demands for low heat losses and energy intensity of a building influence energy calculations. Higher demands are placed on the accuracy of the calculations. An important part of the thermal engineering calculations is the determination of the correct boundary conditions. An important input factor is primarily the indoor and outdoor environment, and temperature is the most important parameter for these types of enviromnent. It is not always the temperature of the external environment, but the environment that is adjacent to the soil or to unheated or differently heated spaces. The possibilities of modeling temperatures below the object are described in the standard ČSN EN ISO 10211. This standard specifies details for a geometric model for the numerical calculation of heat flows to assess the total heat loss of buildings or parts thereof, as well as to derive linear and point heat transfer factors. Furthermore, to calculate minimum surface temperatures to assess the risk of surface condensation and to determine the surface temperature factors. These are two different computational models. Therefore, it would be appropriate to simplify these calculations by simplifying the boundary conditions, namely to conduct an isotherm at a certain level below the terrain, which will be considered as a boundary condition, which is also based on long-term experience with "frost-free" depth. This calculation would be unambiguous, clear and simple.
Guesthouse Zátoka
Rajchl, Filip ; Šteffek, Libor (referee) ; Ostrý, Milan (advisor)
The aim of my thesis is to design new Guest house called Zátoka near the Pozlovice dam. Thesis is divided in three parts. First is part is focused on building design and construction. Second part is focused on HVAC design and renewable energy sources. Third part is focused on advanced application of BIM in building design. Guest house is two – storey building but there is one more underground storey for sport activities which is not part of the building service, but it is part of the design. Ground floor contains three guest rooms, office, utility room and air condition room and of course wind lobby and entrance hall with stairs. In the second floor we can find four guest rooms and corridor. Heating in the building is secured by pellet boiler with storage reservoir. Ventilation is provided by two air condition units. And cooling is secured by one cooling unit on the roof. Each room has radiators and cooling distribution units and ventilation. On the roof we can find 26 photovoltaic panels. Third part is focused on digital model of the building. Each part of the model contains information and whole model is one big database of information about the building which can be used through the whole life cycle of the building.

The building site contains also an outdoor car park and a park.
Office Building
Marek, Václav ; Ostrý, Milan (referee) ; Struhala, Karel (advisor)
The thesis describes design of an L-shaped two-storey office building in Chotěboř, which can work with saving energy and be careful to nature. Using renewable materials and new technical equipments. At the end of the design, there should be a building that will be architecturally interesting, energy-efficient and use renewable resources. It is a two-storey building, which is designed for office working and one part of building can be used for teaching science. Main roof on administration part has saddle shape, second roof on part which science centre has flat roof. Both roofs are intensive green roof overgrown with plants. For day illumination, there are design French windows with openings parts. Most of the first floor and the whole second floor belongs to offices and auxiliary staff rooms, toilets, etc. First floor also includes a small training centre with one classroom and necessary facilities (toilet, staff room, etc.). The load-bearing structures (foundations, walls, columns, floor and roof slabs, etc.) are designed from cast-in-place reinforced concrete. Load bearing vertical elements are walls, columns, and posts. Part of the first floor exceeding the layout of the second floor is covered with a flat green roof. Second floor is covered with a saddle green roof. All drawings and 3D rendering were done using ArchiCAD software.

The kindergarten is designed with capacity of 48 children split into two departments. The second part is devoted to the design of HVAC systems. The building uses mechanical ventilation with heat recovery, heating is provided by two gas boilers and the need of electricity is provided by a photovoltaic system. Captured rainwater is used effectively. The third part values the building regarding the method of multi–criteria analysis. For this evaluation uses national method SBToolCZ.
PCM-based heat and cold storage
Němec, Lukáš ; Ostrý, Milan (referee) ; Šikula, Ondřej (advisor)
In the first part of the bachelor thesis I will deal with the accumulation of heat and cold using materials with phase change and also the design of a PCM storage tank. The aim of my effort is to design the most ideal spacing of tubes in a given tank, so as to achieve the greatest possible heat capacity. I performed simulation experiments in CalA 4.0. The second part is computational, where I focus on the design of heating in the pension. I solve heating with an air-to-water heat pump. I designed solar collectors for hot water heating. The last and third part is the project, which contains the project documentation together with the technical report.
