Design of board for solar fotovoltaic cells
Kulhánek, Martin ; Urbanec, Libor (referee) ; Venclík, Jiří (advisor)
The purpose of this dissertation is to discuss the engineering design of the supporting structure for solar photovoltaic panels with a total area of 200 metres square. The supporting structure is intended for implementation as part of a solar power station. The preamble of the dissertation examines photovoltaic power stations, their types, advantages and disadvantages. The focus of the second part is directed toward the project of constructing the supporting structure and it also deals with the tasks of attaching the photovoltaic panels and putting the panel’s supporting structure in place. This section will also propose methods of continuously monitoring both the panel and its support-structure once they have been constructed and brought into operation. The purpose of part three is to perform the calculations concerning the entire structure’s required load-bearing properties through the use of the Final Element Method in the program “ANSYS 11.0”. The conclusion of this dissertation is devoted to the evaluation and economic analysis of the construction.

Design of heating system for low-energy family house
Kytýrová, Zdeňka ; Hejčík, Jiří (referee) ; Košner, Jan (advisor)
This diploma thesis deals with the design of a heating system for a "low-energy" house. It is conceived as a low temperature system using a combination of radiators and underfloor heating. The design is supplemented with a calculation of heat loss, a proposal of needed components, a scheme of the system and means of regulation. The second part solves the heat source selection. A solar system with vacuum tubes is used as the primary source. The second one is an electrical water heater located in the accumulation reservoir for the hot domestic water. Necessary calculations for the design of the solar system, together with a scheme and means of regulation, are enclosed in this section.

Pension
Koršala, Martin ; Řezníček, Petr (referee) ; Hradil, Dušan (advisor)
The subject of this final thesis is the preparation of a project documentation for the building construction of a new pension with restaurant and wine cellar. The compound is located in Vážany nad Litavou. Its location falls under Velké Pavlovice area. Due to the location in this wine-growing region is in the project located, a wine cellar with a vineyard. The project is designed as a guesthouse with the restaurant designed for families with children, and for holding small social or company events. For this purpose, is in the main building designed a lounge with capacity of 20 people and a restaurant with capacity of 60 persons. The accommodation capacity provided in the pension is 43 beds. Pension offers background designed for relaxation or wellness stays thanks to the sauna and whirlpool. The building has rectangular plan on two basements and two above-ground floors with a mono-pitched roof facing south. This makes it possible to use solar power from the roof and south-facing facade. Water from the roof of the building is collected in a small pond, which serves as a storage reservoir useful in case of fire and vineyard irrigation. Near the building there are paved and parking areas.

Power sources in the Czech republic concentrated on using biomass
Vacek, Tomáš ; Liedermann, Pavel (referee) ; Špaček, Jaroslav (advisor)
This article introduces independent sources of electric energy in the Czech Republic, the different types of power plants, their productivity and the quantity of electric energy delivered to the main distributor. In our country, as well as around the world, commonly used fuels are fossil fuels- coal, crude oil, and gas. As the demand for energy grows, those supplies are slowly running out. Not to mention that those fuels have a negative environmental impact. They are a source of carbon, which causes damage to the atmosphere and leads to global warming. Power plants which do not produce carbon are much safer for the environment, and much more productive. However, the residue of this energy is challenging to dispose of. Nuclear energy has common attributes with renewing the sources of energies that are extremely friendly to our environment. Nuclear power plants also produce enough energy and with the usage of Fourth generation reactors, they will be able to recycle the nuclear fuels. Today, more importance is put on renewing sources which are more gentle for the environment. In the near future, CEZ Company, the largest producer of electric energy is planning to use water energy. Water energy comes from water plants or dams. Other ecological forms of energy include geothermal and solar energies. These two types of energy are not as applicable for our geographical position. Geothermal energy is commonly used on islands where there is an abundance of natural hot springs. The most discussed source of energy is bioenergy. It uses natural wood sources, recycled wood products, and applies bioenergy as a main source for thermal power plants.

Energy efficient mountain chalet
Váňa, Václav ; Bečkovská, Tereza (referee) ; Bečkovský, David (advisor)
Diploma thesis solves project energy efficient mountain chalet in a sloping terrain. The building is located in the Protected Landscape Area Jeseníky near the nature reserve Pod Jelení studánkou. Object is located on plot number 91 in the cadastral Žďárský potok on the site of the initial burnt chalet. Objective of the proposal was ensure maximum energy self-sufficiency of the chalet. Built-up area is 496,47 square meters. The building has one floor, basement and attic. Object is used for temporary accommodation and restaurant services. Perimeter and interior bearing walls in the basement and ground floor are made of calcium silicate blocks, the attic has a timber frame walls made of KVH profiles. Ceiling plates are monolithic reinforced concrete. Cottage has a saddle roof with dormers, slope of the main part the roof is 40°. Entrance doors and windows are made of wood from Slavona. Included the diploma thesis is also seminar work on the topic of supporting structural systems of timber structure.

Energy efficient mountain chalet
Němec, Ondřej ; Bečkovská, Tereza (referee) ; Bečkovský, David (advisor)
Master´s thesis is based on the design of energy efficient huts in the mountain resort Čenkovice . The specified property is currently located existing building mountain rescue . Land is the bigger size , medium steep , overgrown with trees higher . The existing building is of timber construction and is already inadequate to the needs of mountain rescue . The concept of the new HS object is to achieve the lowest power consumption of utility power to operate the building and to endeavor the least possible burden on the environment during construction. The new building is designed largely from natural materials , mostly of wood that form the supporting structure and it is well insulated. The house is rectangular in shape , with 2 floors and galleries. The first floor serves HS , second floor stay for ski school instructors . The rooms are oriented to the southwest side . The building uses solar energy to power and ventilation is forced.

Heating the house with "nearly zero" energy consuption
Lacina, Martin ; Hořinková, Lucie (referee) ; Horák, Petr (advisor)
The main content of this master thesis is the proposition for the heating of a multi-purpose building. The aim of this project is to find the best way how to manage heating with "nearly zero" energy consumption. In the first part of the thesis there is a description of currently the most common systems leading to energy savings. The second part consists of three possible technical alternatives, containing technical solutions for this particular building with the regard to the requirements of the task. The third part then consists of the chosen solution.
