Energy Efficient Building of a Family House
Palátová, Zuzana ; Wierzbická, Helena (referee) ; Vendlová, Lucie (advisor)
This balechor’s thesis deals with a project of newly designed nearly-zero energy building in Hrachovec. It has two parts – first part presents documentation for building permission which contains drawings, fire safety design, building physics, energy performance certificate and the second part deals with design of building services which contains concept design of all systems. The building has two storeys, rectangular shape, strip foundations, ceramic mansory walls and gabled roof extending over a carport on one side. The ground storey can be entered from carport. There is a kitchen connected with a living room, a bathroom, a toilet, a utility room and a storage room. In the first storey, there are two bedrooms, master bedroom, workroom and a bathroom. Concept design of bulding services contains mechanical ventilation with heat recovery, cooling, water supply, heating, sewage system, rainwater management, electrical installation and design of photovoltaic panels. Mechanical ventilation with heat recovery is located in a utility room. Space heating is provided via air-water heat pump with floor heating. The outdoor heat pump unit is located on southeast side of the building. The indoor heat pump unit is located in a utility room. Space heating in the bathrooms is complemented with towel radiators. In the living room, there is a stove. Electricity is produced by photovoltaic panels and the building is connected to a service line. The building is connected to the sanitary sewer. Stormwater sewer is connected to a stromwater tank and blocks for soaking. The stormater will be used for watering the garden.

Analysis of ageing of selected materials used in sewage systems
Horák, Marek ; Stanko,, Ing Štefan (referee) ; Tlolka, Jan (referee) ; Raclavský, Jaroslav (advisor)
The doctoral thesis deals with analysis of the ageing of concrete and reinforced concrete pipes in sewage systems. The ageing of the sewage system is caused by several reasons, for example material abrasion, chemical and biological corrosion and subsequent static overload sewer construction. One of the common causes of degradation of sewage systems made from materials bonded with cement sealant is biogenic sulphate corrosion. Due to the corrosion the degradation of the pipe walls accelerates, particularly in upper part of the pipe and reduces planned lifetime of the sewage system. There is proposed new ageing analysis monitoring method for observation and evaluation of the loss of thickness of concrete and reinforced concrete pipes, which is caused by biogenic sulphate corrosion. Residual lifetime is calculated from the expected corrosion rate, it`s the loss of wall thickness on the monitored section of the sewer system. There is designed the monitoring system of the loss of wall thickness on the sewage system for practical application of the measurement procedure, which is administrated in cooperation with the BVK, a. s. The thesis uses existing knowledge regarding this subject. We use this information for better understanding of the process of the loss of wall thickness in sewage systems in real time and the posibility to correct and in-time implementation of appropriate operational measures. This should cause the limitation of the degradation process of piping material while extended service life and safe operation in sewage systems within the required time period. Based on the methodology is proposed to determine the residual life of the sewage system and maintenance and rehabilitation can be done more effectively. There is needed to be noted that only long-term monitoring period can bring a better overview of the technical condition of sewage systems in time and thus better and more effective maintenance and rehabilitation, which is related to the effective u

Use of heat from wastewater
Tlašek, Miroslav ; Vachovec, Roman (referee) ; Hlavínek, Petr (advisor)
The bachelor thesis deals with the problems associated with heat recovery from waste water and energy intensity of wastewater treatment plants. Current technologies allow you to recover heat that was inserted into the hot water. These technologies can be used for small performances in houses and for large building amenities too. It has been shown that by using a heat pump, low-potential heat waste water can be converted into useful heat for heating and hot water. Not only these heat pumps are environmentally friendly environments, but they can also compete with traditional sources of heat. The aim of the study was to describe these technologies and to minimize the energy that is wasted us „will drain into the canal“.

The study of selected rehabilitation of sewer network
Lžičař, Jakub ; Habr,, Vladimír (referee) ; Raclavský, Jaroslav (advisor)
The diploma thesis deals with sewage systems, evaluation of their technical conditions and various methods of sewage system reconstruction. First chapters provide theoretical background for sewage system reconstruction and contains general information about sewage systems and basic terminology. Next chapters describe the theoretical procedure of elaboration of proposal of existing sewage system remediation including the evaluation of technical conditions of sewage system and the evaluation of individual technical indicators. Then, individual methods of sewage system reconstruction are described. The second part of diploma thesis deals with the case study of sewage system in the village of Mikulovice. The case study is elaborated according to procedure specified in the theoretical part of diploma thesis. The case study includes the passportisation of sewage system and the evaluation of technical conditions of three selected sections. On the grounds of discovered defects, the methods of sewage system reconstruction are designed. Finally, each section of sewage system is evaluated and optimal method for its reconstruction is selected.

Rainfall data in urban drainage
Mrázek, Jan ; Prax,, Petr (referee) ; Raclavský, Jaroslav (advisor)
The aim of the bachelor thesis is to process knowledge from measured precipitation data and aplicating this knowledge on methods of prepration of a hydraulic sewage network model of Znojmo city. The first part is a research in the field of interest, being sewage network and precipitation data processing. The detailed procedure of modeling and quantification of the measured data is explained in the practical part of the thesis. After that the process of inputting the data in to a hydraulic model in MIKE URBAN, the program which draws topological data from GIS (retained by VAS a.s. as the investor) and exports the final model into a SWMM enviroment. At last but not least the thesis focuses on schematization of the objects situated on the sewage network, such as relief chambers. The result is a noncalibrated and nonverified model of a part of sewage system of the Znojmo city and systematically organized measured critical rains. This model is going to be optimized after this thesis is finished, thus also calibrated and verified.

Cagášek, Radim ; Helcelet, Marek (referee) ; Raclavský, Jaroslav (advisor)
This work deals with the evaluation of the technological state of the sewerage network, as well as the subsequent method of remediation for each failure. The first part contains the accompanying report. This report includes information on the municipality in which the evaluation of the technical condition of the sewerage network took place. Next section includes the actual technical report which has data on the sewage network and its inspection. There are also information about the evaluation of the network‘s technical condition and viable ways of its rehabilitation. At the end of the section there are suggested possible ways of remediation for each of the detected failures. In the next chapter there are calculations for construction technical indicators and the calculation of the capacity of the sewerage network. The last section contains technical data sheet listing the faults of the individual sections and geodetic focus on manholes.
