Concrete with Bio-Based Aggregates
Vrzáň, Jakub
This article focuses primarily on concrete made from plant-based aggregates (rapeseed and hemp straw) coupled with a binder (lime-based and water glass). These materials may represent a way to ensure the sustainable production of building structures with high insulation properties. It is necessary to have thorough knowledge of the behaviour of such materials in order to improve their applicability in diverse construction projects around the world. The main finding of this paper is that a composite material composed of locally available secondary agricultural raw material and lime binder exhibits excellent thermal properties.

Influence of Insulating a Building for Family Holiday on the Expenses Related to its Operation
Hanyk, Tomáš ; Hrdlička, Tomáš (referee) ; Čech, Josef (advisor)
This diploma thesis deals with the impact of thermal insulation on expenses relateted to the operation of the weekend house. Theoretical part describes options of thermal insulation systems, insulation methodes, describes structural prices and costs. Practical part of this thesis describes heat costs on specific weekend house situated in Karlovy Vary region. Thermal insulations are designed in three different variants. Calculation of costs of every designed insulation systém is included in this thesis. In next part of thesis is calculated return of investment for every designed solution. In conclusion of the diploma thesis are compared impacts of thermal insulation on expenses ralated to the operation of the weekend house.

Assessment of investment in heating house
Zdražil, Pavel ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The bachelor´s thesis deals with economic evaluation of investment in insulation and heating and resulting operation of boilers in a family house. The calculation of thermal design power, which is needed for heating, was made according to norm ČSN EN 12831 for the house in actual state without insulation. Further were suggested two options of insulations and modernization of windows, for reduction of heat loss. Then was calculated the thermal design power for the two new options, again according to norm ČSN EN 12831. Next were presented possibilities of heat sources. For the specified family house was chosen a gas boiler in classical and condensing implementation for all three variants of insulation. These all options have made six variants which were compared together and evaluated. In the conclusion were excluded four variants economically disadvantageous and was chosen one of the final two variants as the best suggestion for the specified family house.

Detached house
Bobek, Michal ; Žižka, Lukáš (referee) ; Vajkay, František (advisor)
This bachelor thesis deals with design and creation of project documentation for realization of object of family residence in the Radotín, Prague 16. The parcel 2087/66 determined for object is located on the cadastral territory of Prague 16 and it is suitable for construction of quite formidable family houses and buildings of villa house character. The surrounding development is not older than 5 years. The design respects spatial plan and it does not stand out of character of sourrounding development. The attached project documentation is created in concordance with actual valid laws, notices and norms. The solved object is a building of bigger family residence with two overground floors, without basement and with garage for two cars. It is assumed that the building is to be used by five people. The object contour is irregular and roofs are done by two flat roofs. The construction systém of walls is designed as aircrete block system. Object is composed from one housing unit with all accessories.

Household cost analysis
Havránková, Denisa ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The diploma thesis deals with the analysis of the cost of a house in the area of peripheral constructions and the effect of thermal insulation on energy consumption for heating and hot water. The theoretical part generally defines renewable energy sources, heat sources, thermal transmissions and structural losses, basics of valuation of construction works and supplies and overview of state subsidies. In the practical part are proposed composition of peripheral constructions, calculation of heat transfer coefficient of all designed perimeter structures and their subsequent evaluation. Furthermore, there is an estimated annual energy demand for heating and hot water and annual electricity consumption in the household. At the end of diploma thesis is a proposal of suitable energy sources and calculation of the return on investment in these sources.

House for dwelling and business
Kolářová, Andrea ; Svatoňová, Hana (referee) ; Mohelníková, Jitka (advisor)
Bachelor thesis project addresses the single-family house with a business background. The building has two floors, partial basement and second floor above ground is designed as an attic. The supporting elements of the structure are designed with brick system POROTHERM. External walls in the basement are formed shuttering blocks BTB. The roof of the family house with a business background is gabled roofs with tiles of shuttering BRAMAC Nature. The project focuses on design documentation and detailed elaboration of details. The project also includes technical reports, hygrothermal assessment, fire safety design and technical design of the building.

Design of HV disconnector
Hrubý, Radek ; Valenta, Jiří (referee) ; Vávra, Zdeněk (advisor)
The text focuses on the design of high-voltage disconnector. It made a brief theoretical analysis of construction equipment directives. Proposal follows the insulation system apparatus according to empirical formulas. Hereafter, we discuss the design of current track isolators. For the flow path are calculated electrodynamic forces acting. Warming current path is simulated by a computer program ANSYS, this simulation includes 3D device model and determine the material and thermal constants. Finally it is shown calculating the required torque on the shaft of the disconnector. This calculation is simplified. The output is a 3D sketch of the device model used to simulate warming.

The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation
Machová, Petra ; Kosová, Jaroslava (referee) ; Čech, Josef (advisor)
The topic of the diploma thesis „The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation “ is a draft and appraisal of four variants of thermal insulation of the building. The thesis deals with the assessment of the current proposal for apartment building envelopes along with proposing alternative plans with emphasis on reducing heating costs. The first section describes the types of buildings according to heating demand and a list of different variants of thermal insulation materials. The second part is devoted to a specific apartment building in the Ústí nad Labem for which there are designed in four variants of insulation. The work includes thermal assessment in original condition and the assessment of new condition modified by adding thermal insulation. Through research will bedetermined price of implementation of proposed insulation options together with the costs of operation of the apartment building. In conclusion, the diploma thesis evaluates the payback period of insulation.
