Application for Aiding Solar Panel Positioning
Mudroň, Marek ; Bambušek, Daniel (referee) ; Herout, Adam (advisor)
Táto práca podrobne popisuje vývoj a iteratívne testovanie webovej aplikácie určenej na odhad solárneho výkonu fotovoltaických systémov. Hlavným cieľom bolo vytvoriť používateľské rozhranie (UI) a poskytnúť intuitívnu používateľskú skúsenosť (UX), cielenú pre amatérskych používateľov zaujímajúcich sa o fotovoltaické riešenia. Aplikácia umožňuje používateľom vybrať si geografickú polohu stavby, použiť textúru mapy pre jej namodelovanie a umiestniť solárne panely na strechu v zapojení podľa vlastného výberu. Používatelia môžu do systému pridať aj svoje vlastné modely panelov. Aplikácia využíva simulačný model na odhad výkonu navrhnutého systému. Nakoniec prezentuje výsledky predstavujúce očakávaný výťažok elektrickej energie.

Detached house in Horní Stakory
Hornychová, Anna ; Melcr, Petr (referee) ; Fišarová, Zuzana (advisor)
The aim of this bachelor thesis is to design a nearly zero-energy detached house. It is located in Horní Stakory near Mladá Boleslav. The project is divided into two parts. The first part is the documentation for the construction of the building. The second part focuses on the internal environment of the house especially the heating system. It is a two-storey L-shaped building with an attached garage with a flat roof. The main part of the building has a gable roof. The first floor of the building is designed as a living area – living room, study or guest room, bathroom, utility room. The second floor is designed as private – bedrooms, bathroom and WC. The building is based on concrete foundation strips. The vertical structures are masonry made of sand-lime bricks. The building is insulated with the ETICS. Horizontal load-bearing structures are made of reinforced concrete. Heat losses through ventilation are eliminated using a mechanical ventilation unit with heat recovery. The heat pump will heat the supplied air and provide water heating for the underfloor heating. The main building will be heated by underfloor heating supplemented by electric towel heaters and occasionally by an electric heater in a non-heated garage. Solar panels will heat the hot domestic water. Electrical energy will be supplied from photovoltaic panels located above the garage and from the grid. Rainwater will be accumulated in a storage tank and used further for watering. The excess rainwater will be soaked up.

Energy-saving family house in Jablunka
Mrnuštík, Petr ; Vrána, Jakub (referee) ; Počinková, Marcela (advisor)
The bachelor’s thesis focuses on designing a low-energy detached house in village Jablunka. Thesis is divided into two parts, first one is aimed at structural and architectural design, whilst the second one focuses on building services, especially heating with solid fuels. The house is divided into a two-storey and a single-storey part. Ground floor includes master bedroom, utility room and mainly open-plan living room connected to kitchen which opens onto a deck and garden. First floor then includes two bedrooms and study. Both floors have their own bathrooms with separate toilets. Structural system is designed as masonry walls from aerated concrete blocks, which are transferring load onto plain concrete foundation strips. Floor slab is to be made of reinforced concrete. Two-storey part is covered by prefabricated rib–and–filler gable roof with 15° slope, from aerated concrete fillers and reinforced concrete, the one-storey part has flat roof. Walls are insulated by 140 mm of mineral wool, plinth then by 120 mm of XPS. Ground slab will be insulated by 220 mm of graphite EPS, floor slab is insulated by 40 mm of impact sound insulation from mineral wool and 50 mm of EPS with installation layer. Flat roof is insulated by 220–340 mm of mineral wool with screed to fall function. Gable roof is then insulated by 180 mm PIR panels. Rainwater will be collected and stored in rainwater tank for gardening use, overflow will then lead to drainage blocks, where the water can be absorbed into soil, with overflow into stormwater sewer system. Ventilation is designed equal pressure, mechanical with enthalpy heat recovery exchanger and heating battery covering ventilation losses. Main heating source is solid fuel boiler, storing its energy in 750liter hot water tank, from which is the heat distributed into 200liter domestic hot water tank, ventilation heating battery and heating elements such as convectors, panel and rail radiators. As renewable source of energy is designed photothermal panels which will mainly heat domestic hot water, excess heat will then be stored in hot water tank.

Návrh autonomní robotické kolové platformy
LARVA, Jaroslav
The diploma thesis represents the project of design and implementation of an autonomous robotic platform, which is built on the basis of a modified children's buggy, enabling its remote control. The entire project is systematically divided into two basic parts: theoretical and practical. In the theoretical part, the components and software tools used during the project are analyzed in detail. This section provides an overview of current trends in robotics and autonomous systems and highlights the importance of each selected element to the success of the overall design. In the practical part, the work focuses on the development process itself. From the first steps in construction, through the programming of the purchased platform, to a detailed description of the connection and integration of electronic components. Specific attention is paid to technical solutions that overcome the challenges associated with adapting a children's buggy to an autonomous robotic platform. In the final part, the project is evaluated as a whole. It includes an analysis of the achieved results, reflection on possible areas of improvement and discussion of future directions of development.

Inovation of a photovoltaic power system with battery storage
Pallová, Ivana ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
This diploma thesis is focused on the Innovation of the existing power plant with battery storage. In the theoretical part, the individual parts of the photovoltaic power plant are introduced, the principle of operation of the photovoltaic cell and the individual types of these cells are desribed. The work also deals with the description of the existing photovoltaic power plant and their components. Subsequently, a battery systém and otherpossibilities of Innovation with the possibility of a subsidy and without it are designed. In the final part, the most advantageous solution is evaluated according to the performes simulations.

Utilization of renewable energy for heating
Foit, Vladimír ; Hejčík, Jiří (referee) ; Chovancová, Michaela (advisor)
This bachelor's thesis, titled Alternative Heating Options, is divided into four parts. First, an overview of renewable energy sources available in Czech Republic is presented. Second part contains Czech energy policy and legislation and several grants related to renewable energy sources. Third part lists several projects constructed in Czech Republic including a description of a specific project on a residential house. Last part aims to design a heating system for a building using one of already referenced methods and to compare it with other heating systems. The returns of the design is also discussed.
