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.

Comparison of photovoltaic and photothermal systems for hot water heating in an apartment building
Švéda, Richard ; Lachman, Jakub (referee) ; Toman, Filip (advisor)
This bachelor's thesis examines the comparative merits of photovoltaic and photothermal systems for domestic hot water heating. The introductory section provides an overview of solar radiation, its origin, and its striking the Earth´s surface. Thereafter, both systems are subject to detailed analysis and calculations. These systems are designed for a specific residential unit and evaluated from technical, financial, and operational perspectives. Based on these calculations and analyses, the most suitable choice for the given location is recommended.

Alternative energy sources for family house
Stacha, Radek ; Fortelný, Zdeněk (referee) ; Škvařil, Jan (advisor)
Bachelor thesis is focused on alternative sources of energy for the house and their evaluation. The first part focuses on the general view on alternative energy sources and making explicit the house of each resource of which the assessment is undertaken. The next chapters are focused on each types of renewables for which will be the conclusion in the end of each section for the assessment of a given house. The conclusion is evaulated for the selected type of alternative energy resources towards normally used ones.

Energy saving of large objects
Řehák, Pavel ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma thesis is to evaluate the economical measures using own heat and power production using cogeneration units, use of renewable resources to partially cover the consumption of objects, reduction of thermal losses by evaporation in the outdoor swimming pool and overall increase of waste heat utilization by exchanger heat exchangers from flue gas and heat from waste water.

Solar Energy Applications in Houses
Jankůj, Tomáš ; Špiláček, Michal (referee) ; Poláčik, Ján (advisor)
This thesis is focused on photovoltaics and photothermics. Their source is solar radiation that belongs to the category of renewable sources. At present, great emphasis is placed on ecology and economics. For this reason, renewable sources are coming to the foreground. In the first part of the bachelor thesis, types of photovoltaic cells, technology and their efficiency are presented. Furthermore, the principle and construction of photovoltaic and photothermal systems are described. The second part describes the design of the energy solution of a family house using solar energy.

Utilization of Photovoltaic Energy for Water Heating in Family House
Fryšták, Tomáš ; Morávek, Jan (referee) ; Toman, Petr (advisor)
The task of the work is to bring the issue of utility water heating closer together and to design a system that would be feasible in the layout of the building and constitute a fully-fledged replacement, even improvement, of the existing utility water heating system. The issue is viewed from two perspectives. From the point of view of using a photovoltaic system with a transducer and an electrical spiral, and from the point of view of using a photothermal system where the sunlight is directly converted to heat and its subsequent storage. It then compares several variants of a similar system from the economic and functional side.
