Cost comparison of houses made of classic materials and houses made of natural material
Lošáková, Jana ; Gilar, Ing Přemysl (referee) ; Výskala, Miloslav (advisor)
This diploma thesis is focused on a comparison of construction cost of the house made of classic materials with the equivalent made of natural building materials and consequently on comparison of both construction variants. In order to perform those tasks, the used natural building materials were defined. Furthermore, the specific options of usage of these natural building materials as well as the used composition structures were introduced. The thesis concludes with a price calculation of the constructions made of natural building materials which were not available in the common budgetary software. The appendix of the thesis contains budgets for the first variant, where the house is made of natural building materials, and also for the second variant, where the house is made of classic materials.

Alternative construction - clay houses
Smékalová, Kateřina ; Vaňková, Lucie (referee) ; Krejza, Zdeněk (advisor)
The thesis deals with alternative construction based on natural and renewable materials. A part of the thesis is processing of legislative, technical and material possibilities. Accent is put on cost-oriented price, market price and analysis of individual construction parts of the building with the final economic evaluation of the case study.

Solid Particle Emissions from AgroPellets Combustion
Svoboda, Marek ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This thesis is divided into two parts. The first part deals with defining the main concepts, properties of biomass and pellets. Further, the procedures for measuring agropellets properties according to valid standards are mentioned. The following is a selection of the raw materials for the production of agropellet, with the determination of their properties. The theoretical part closes background research emissions from combustion and emission standards for a solid fuel boiler. The second part is an experimental one, which determines the formation of solid pollutants in combustion of four types of pellets made from alternative sources. Here are the graphs of the gaseous emissions of each of them. At last there will be a comparison of emissions agro pellets with more widespread wood pellets.

Steam boiler with grate firing burning wheat straw
Křivák, Petr ; Kohout, Přemysl (referee) ; Lisý, Martin (advisor)
The aim of the thesis is the design of the steam grate boilers of 40 t/h for straw burning. The required parameters are generated steam temperature 420 ° C and a pressure of 5.5 MPa. The specified fuel is cereal straw with a calorific value of 9.5 MJ/kg. The calculation is made from the stoichiometric calculation of elemental analysis, to calculate the individual dimensions and heating surfaces of the boiler.

Detached Family Residence
Mikuš, Martin ; Vávra, Petr (referee) ; Vajkay, František (advisor)
The subject of this work is the design of a detached family house in area Nove Domky near Jihlava in which natural construction materials were used. Instead of concrete or bricks, this building is designed with materials such as straw, rock, timber, clay, hemp or sheep's wool. Furthermore, the work deals with methods of plumbing, electrical installations and heating. The possible utilization of natural energy resources or ecological processing of waste were also taken into account. The conclusion contains the financial comparison with a building where traditional and industrially produced materials are used.

Design of single-purpose cutting machine for shortening of plant stems
Žižka, Jakub ; Brandejs, Jan (referee) ; Vespalec, Arnošt (advisor)
This bachelor thesis deals with the design of a single-purpose machine for cutting plant stems. The task of the machine is to cut already partially shortened and stripped wheat straw stalks to the required length. The operation of the machine is fully automated, the operator only ensures the supply of semi-finished products to the machine, removes the finished stalks and controls the operation of the machine. In the thesis is a search describing the existing technologies used for cutting plant stalks, the possibility of driving a single-purpose machine and possible solutions for transporting stalks. The research also includes an analysis of the necessary mechanical and physical properties of wheat stalks. Subsequently, the analysis of information from the research part of the thesis and the definition of important parameters for the design construction balance sheet is performed. In the practical part of the work are developed concepts of possible solutions of individual structural nodes and justification of the choice of individual solutions. The second part of the practical part deals with the construction design of a selected conceptual design, including calculations. The work shows a possible solution for the construction of a machine for processing semi-finished products with a large variety of shapes.

Newly-Built Detached House
Manduch, Dávid ; Soudek, Pavel (referee) ; Kalousek, Lubor (advisor)
This bachelor thesis is about a two-storey detached house with no basement and the living roof which is covered with vegetation. The house includes two wooden terraces. The entrance terrace is located in front of the main entrance of the house and the second terrace for relaxing has access from the living room with the kitchen unit. This terrace is also the entrance to the garden. The main building material of this house is Ecocon wall paneling which is combination of wooden frame and straw filling. The garage is self-standing and one-storey object with no basement.It's also roofed with the living roof.

The optimalization of clay building components
Melichar, Jindřich ; Šiler, Pavel (referee) ; Opravil, Tomáš (advisor)
Clay building components are nowadays one of the most used building materials in the world. Except easy availability and processability clay building components have also heat storage function. This master´s thesis will be considering possibilities of improving thermal and mechanic properties of these materils by additing suitable reinforcements.
