The aim of the bachelor's thesis is to develop project documentation for a building permit for a new family house. The new building is situated on the edge of the built-up area of the village of Domanín near Uherské Hradiště. It is a two-story house with a gable roof, a cellar and a garage next to the house. The floor plan of the building is rectangular. The house has 142 m2. The vertical load-bearing wall is made of burnt blocks filled with mineral wool. The horizontal construction system is designed from a prefa-monolithic system. The roof structure on the house is a truss. On the first floor in the northern part of the house there is a vestibule, utility room, bathroom and separate toilet. The living room and kitchen are oriented to the southwest. On the second floor there are two rooms and one bedroom, a common dressing room, a bathroom with a shower and a bath and a separate toilet. 10 photovoltaic panels are designed on the house, which will cover the electricity consumption from May to September. The MVHR is located in the utility room. From the utility room, the wiring is located in the ceiling voids. The system is designed to provide a background ventilation rate of 330 m3/h. The house is heated by underfloor heating supplemented by towel radiators in the bathrooms. The hot water cylinder tank accumulates warm water from the air to water heat pump. Domestic hot water is supplied from a 230l hot water tank. Rainwater will be channeled into a accumulates tank and subsequently used to water the garden. The project includes a thermal and technical assessment of the building, an assessment from the point of view of acoustics and daylighting, and an assessment of the fire and safety solution of the building. The project documentation was developed in the Archicad software.

Car showroom ventilation with workshop
Kordula, Lukáš ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The bachelor thesis titled "Air Conditioning for an Auto Salon with Workshop" focuses on designing an air conditioning system for an auto salon with a workshop for cars located in Brno. For the facility, we have designed two air conditioning units, with one serving the auto salon and the other serving the car workshop. The unit for the auto salon aims to cool during the summer months and heat during the winter, while for the workshop, the goal was to extract harmful emissions from the workshop environment. The thesis employs methods for designing air conditioning systems, including selecting suitable equipment. The outcome of the thesis comprises two proposals for air conditioning units tailored to the needs and conditions of the auto salon and workshop environment, with an emphasis on energy efficiency and sustainability. The theoretical part focuses on acoustics in HVAC systems. The computational part addresses the individual steps necessary for designing the air conditioning unit. Software tools used in the design include Teruna and AeroCad. The project part develops the necessary project documentation within the specified scope.

Room acoustic modeling
Bernát, Michal ; Balík, Miroslav (referee) ; Míča, Ivan (advisor)
This Master's Thesis deals with geometric modeling methods and theirs implementation in Octave (Matlab), which is ideal for the practical realization. The first part of the thesis is focused on a very simplified image source method, which is able to calculate and render the 2D impulse response of rectangular rooms. The next part is aimed on~the same method, but extended by three-dimensional simulation of polyhedral prism-shaped rooms. There is both an explanation of theoretical and mathematical aspects and a~documentation of the implemented source code. Extended image source method is able to generate sound representation of impulse response characteristics, and use it for auralization, which is achieved by using convolution of both the input sound source and the calculated impulse response. At the end there are two practical examples for both methods with explanatory illustrations.

Design of modern speaker body with usage of new technology
Kůst, Martin ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This diploma thesis deals with the analysis and design optimization of a speaker cabinet (enclosure) produced by the additive technology of 3D sand printing. The introductory part is devoted to the theory, both in the field of noise, vibration and the method of their calculations, as well as the theory of speakers and their systems. Numerical and experimental modal analysis is performed, which were compared to determine the mechanical properties of the new material, including material damping. This is followed by experimental and numerical harmonic analysis, with output in the form of a numerical model describing the behaviour of the structure during its excitation. The data are compared with a modal analysis of the internal acoustic space and the critical shapes and their frequencies are determined. At the end of the work, construction modifications are proposed to increase the rigidity of enclosures, the influence of which is evaluated on the created numerical models.

Acoustic emissions of buildings
Smažinka, Josef ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The diploma thesis deals with acoustics with the main focus on acoustic emissions of buildings. The first part of the thesis aims to familiarize the reader with the field of acoustics as a whole. They will learn the basic concepts, quantities and relations that exist in acoustics. In the second part I focus specifically on the sources of noise in buildings and their surroundings, how can excessive noise affect health, what standards must be met and how to prevent excessive noise. The last part is devoted to practical measurements in the field, which is focused on real sources of noise in the city of Brno. The aim of this measurement is to compare the noise generated by buildings with other noises in the urban environment.
