Single-family house in Bohumín
Kadlčková, Markéta ; Bantová, Sylva (referee) ; Krupicová, Jana (advisor)
The aim of the bachelor´s is to design a low energy single-family house. Location of my house is in small town Bohumín next to Ostrava. The entrance in to the house is from southeast side. The bulding has two floors without basement and attched garage with utility room. The bulding has a couple roof and above garage is a flat roof. On the ground floor there are garage, utility room, wind lobby, a storage, kitchen with living room, WC and study room. On the first floor there are two bedrooms for kids, bedroom with walk-in-closet, bathroom and WC. The vertical structures are masonry designed from ceramic blocks with isulated the ETICS contact insulation system. Horizontal loud-bearing structure are designed from concrete. The building is based on foundation strips made from reinforced concrete. The building is conceptual design of eletricity, water supply, sewer pipes, air conditioning and photovoltaic panels on the roof of the building. The photovoltaic panel will be placed on the roof of the building. My main concept design is focused on heating. A floor heating system will be done with hot water in pipes with heat pump. Rainwater will be accumulated in a tank and further used for garden irrigation. Excess water will be infiltrated into the ground no the property. The documentation also includes the Building’s Energy Performance Certificate.

Energy-saving family house in Předměřice
Rybář, Aleš ; Vyhlídalová, Karolína (referee) ; Počinková, Marcela (advisor)
The bachelor´s thesis aims to design a nZEB detached house. It´s located in Předměřice in a relatively quiet area. The building has two floors with an attached garage, workshop, sanitary facilities and storage room. The building has a cold-pitched roof and the attached part has a mono-pitched roof. The ground floor of the house is a social part with a living room connected to the kitchen, study, bathroom, WC, garage, laundry and utility room. The first floor is a private zone with a master bedroom with a walk-in closet, two bedrooms, a bathroom, a WC and a storage room. The building is based on reinforced concrete foundation strips. The vertical structures are masonry made of ceramic blocks. Horizontal load-bearing structures are made of ceramic blocks and reinforced concrete. The house is connected to the freshwater main and sanitary sewer. Domestic hot water is supplied by the 300 l hot water cylinder. Rainwater from the roofs is accumulated for reuse. The excess water is diverted through the overflow into infiltration. Rainwater from built-up areas is infiltrated into the ground. Heating in the house is provided by an air-water heat pump, which is also used for DHW. The heating system of the house is floor heating in combination with electric radiators. On the cold roof there are placed photovoltaic panels for batteries placed in the utility room. The house is partly ventilated by a mechanical system with a heat recovery. The rest of the rooms that are not part of the living area are ventilated by windows.

The analysis of acoustic properties of innovative wood-based materials
Svojanovský, Jan ; Nop, Patrik (referee) ; Jirásek, Ondřej (advisor)
The content of this work is research of innovative wood-based materials in the acous-tic perspective. Basically, the goal is to determine the influence of the internal structure of the wood-based material on variables, which are sound speed, acoustic resistance, or acous-tic constant. In total were measured 15 samples, each one was made in a different way. Each sam-ple was weighted, and the length of its sides was measured. By using the ultra sonic timer, it was measured the time of the sound impulses, which go through the samples in all of their axes for the purpose of observation the influence the fibers on speed of sound in the materi-al. The next thing to do was to determine another magnitude, which describe acoustic of the material. All measurements were taken in room conditions (room humidity). Six of the sam-ples, which were randomly selected from those 15 samples, were measured once again after two weeks. In those two weeks were all the samples saved in air-conditioned place in which was the room humidity distinct lower. In the end all the samples were compared with each other and they were also com-pared with materials which are commonly used in production of musical instruments or acoustic components. Possible use in the music industry was assigned to each sample.

Acoustical simulation of going car
Lacko, Tomáš ; Horka, Michal (referee) ; Sigmund, Milan (advisor)
This project includes an overview of different processing methods phonograms. It focuses primarily on time - frequency analysis carried out using Fast Fourier Transform (STFT). The main essence is to evaluate the time - frequency analysis of recorded motor vehicle, driving at different options, together with an analysis of driver activity in these variants. Based on the results of the analysis deals with the creation of synthetic audio signals of motor vehicle records. Further addresses the creation of the program for acoustic simulation engine is running smoothly when driving a car. Processing recorded signals and their evaluation is transferred using Matlab 7.7.0 ( R2008 )

Flat Plates Noise
Zlámal, Josef ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The master thesis summaries the findings results of a study focused on the spread of noise vibrating flat plates. Part of this thesis is measurements of flat plate noise in the anechoic chamber and finally their processing and evaluation. The next part of the thesis is focused on FEM acoustic simulation and comparing results with measurements.

Noise map
Lokaj, Jiří ; Kubičková, Alena (referee) ; Rozman, Jiří (advisor)
The aim of this paper is to introduce the measurement of noise and create a noise map in a geographic information system. The first part is focused on describing the physical properties of sound in space, atmospheric and physiological acoustics. It also deals with the physiological effects of noise on the human body and technology needed for measure and process noise. Other part describes the structure of a geographic information system and noise map. The last part is about the practical creation of noise maps, includes a description of the real measurement results and evaluation

Spectral analyse of sound in space acoustics
Port, Martin ; Bereznanin, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is an introduction to the problems of acoustics and is focused on the variables describing the noise. The methodology for measuring noise in relation with valid hygiene standards is analyzed in next section. The noise levels at work required by government regulation no. 148/2006 are summarized in a subsequent charter. The next section is an introduction to the analyzer PULSE 3560B from Brüel & Kjar. This work describes a software called Labshop, which is designed to analyze noise and vibrations. It also describes the most common features Acoustilyzer NTI AL1. The practical part was to measure the reverberation, noise, frequency spectrum and plott the distribution of noise with noise maps of various auditoriums.

Home for seniors
Koláříková, Eliška ; Pilný, Ondřej (referee) ; Berková, Petra (advisor)
The aim of the master´s thesis is to design a Residential care home as smart building. It is situated in the centre of Křenovice near Brno. The master´s thesis is divided into three parts, first part presents design documentation, second part is focused on building services and the final part presents noise control in building. Residential care house is designed as two-storey building without basement with flat roof. On the first floor there is utility area for senior house and healthcare facility and on the second floor there are flats for seniors. Residential care house is built on footing. Load-bearing and non-load-bearing walls are designed from hollow bricks type THERM. External walls are insulated with mineral wool. The roofing of residential care house is made up of extensive green roof. The building services of the building includes two ground-water heat pumps with boreholes for heating and cooling, photovoltaic panels, HVAC, hot water cylinder and rainwater storage tank. The final part is focused on noise control in building. It is about acoustic in construction. Noise study is also included.
