Environmentální řešení objektu domu s kavárnou v Zaječí / Environmental solution of a house with a café in Zaječí

Medková, Tereza January 2022 (has links)
In my master's project I design a nearly zero energy consumption house with a café in Zaječí. The 1ST part of this project deals with a structural part of the building, which has two above-ground floors and basement. On the basement are storerooms and rooms for technical equipment, on the ground floor is café and living room with kitchen, and on the second floor are bedrooms, bathrooms and cloakrooms. Footings are from cast-in-place concrete, the load bearing walls on basement are from formwork blocks with cast-in-place concrete, on above-ground floors are from ceramic blocks and every non-load bearing walls are also from ceramic blocks. On whole floor are reinforced concrete floor slab and flat green roof. The 2ND part deals with technical equipment of the building. There are gas boiler, floor heating, air conditioning, mechanical ventilation (HVAC), photovoltaics panels with energy storage, retention tank, external blinds and biodynamic lighting. The 3RD part compares several options for using solar energy in combination with different heat sources in terms of energy and economic efficiency of the building.

Šenkyřík, Adam January 2022 (has links)
The aim of the master thesis is to design nearly zero-energy building of the municipal office in the city of Bojkovice. In the first part an architectural and constructional solution was designed. The building has three above-ground floors. It has a flat green roof with skylights and photovoltaics. First floor includes reception, break room, archives, offices, meeting room, kitchenette, sanitary facilities and boiler room. Second floor consists of break room, archives, storerooms, offices and sanitary facilities. External load-bearing walls, internal load-bearing walls and partitions are made of ceramic blocks. Columns, girders, floor slabs and roof slabs are made of monolithic reinforced concrete. Cladding is insulated with ETICS. In the second part HVAC was designed. Heating is provided by gas condensing boiler. The building is mechanical ventilated by AC units situated in technical room in the third above-ground floor. Cooling is air-conditioned by fan-coil units designed in offices and conference hall, chillers are situated on the roof. The third part of the master thesis focused on design and comparison of various AC units. Drawings are processed in SW AutoCAD, calculations were made in Excel, the design of air-conditioning system and unit was made in SW Atrea DUPLEX 9.10, Aerocad and CLIMACAL.

Energeticky úsporná budova mateřské školy Květinka / Energy-efficient "Floret" kindergarten building

Hajkr, Radek Unknown Date (has links)
The task of the master project is to design a single-storey kindergarten with flat extetensive green roof in Chvalčov. The building contains entrance hall, utility room, locker rooms, toilets, kitchen, school canteen, staff rooms, storage room and play rooms. The Building is divided into two similar parts. The vertical loadbearing structure is designing from ceramic blocks. The horizontal loadbearing structure is designed from reinforced concrete. The building is heated by a ground source heat pump supplying heat to floor heating. Another source of heat for the preparation of hot water and heat exchanger in the air handling unit is a gas condensing boiler. The heat pump in reverse operation cool the building via Fan-coil units. For air distribution is designed galvanized ducts and air handling units. The building uses photovoltaics to produce electricity for safe environment when using a renewable energy source and safe money when they no need buy energy from elektricity distribudion networks. The designs were elaborated in Revit, autocad and thermal assessment in Deksoft and similation 2018

Porovnání výkonnosti fotovoltaických panelů v podmínkách ČR / Comparison of different photovoltaic panels in CR

Červinka, Pavel January 2011 (has links)
This term paper deals about history, principle and use of photovoltaic panel. It describes their stucture and constantly improving properties of these panels. It outlines their gradual generational evolution from beginning to present. Then it describes the various systems involved on – grid and off – grid. It also describes and compares the photovoltaic panels and inverters from different global manufacturer. The end of this work deals about conditions of photovoltaic in the Czech republic and about Hady photovoltaic incubator, which belongs to the company Energ servis a.s. It presents a comparison of different local and the analysis of the impact of shading for the achievement of the photovoltaic panel. It makes mathematic models for calculation of the spacing range and calculation the power loss in a specific shade.

Hasičská zbrojnice a tělocvična / Fire station with gym

Svoboda, Martin Unknown Date (has links)
The aim of the work is to design Fire station with a gym in Olomouc. Diploma thesis has three parts. First from institute of building structures, second from intitute of building services and last part is devoted to modeling and assessment of details of building. Fire station is divided into three parts. Garage for 3 fire trucks, main part and gym with training tower. The main part contains toilets, showers, locker rooms, storage places, offices and facilities for firefighters and office rooms. Structural elements of the building are from reinforced concrete. Infill walls are made from ceramic bloks. Thermal insulation is from mineral wool and cladding of the wall is made of fibre-cement boards. The slab in the main part is made of cast-in-place concrete. Others slabs in the garage and gym are made of prefabricated elements. On the building are desined three types of roofs. Extensive green roof, flat roof with a stabilization layer of river aggregates and roof made of insulating sandwich panels. In the thesis is design conception of artificial lighting, ventilating, heating, cooling, water managment, photovoltaics and management scheme of energy and ecological systems. The work contains project documentation for building permits, which were made in accordance with applicable legal and technical regulations.

Studium optoelektrických vlastností tenkých vrstev organických polovodičů na bázi ftalocyaninů / Study of optoelectrical properties of organic semiconductor thin film layers of phtalocyanines

Miklíková, Zdeňka January 2015 (has links)
Diploma thesis is focused on the study of optoelectric properties of thin layers of organic materials based on phthalocyanines, which can be used as an active layer of photovoltaic cells. Especially are studied the properties of the thin active layers of PdPc and PdPc + IL on the glass or ceramic substrates with aluminium contact, which are prepared by material printing here. On the prepared samples were first measured current-voltage characteristics in the dark and in the light and then were measured impedance spectrums in the dark. The received results will be used to improve the properties and structures of photovoltaic cells.

Heinrichová, Patricie January 2015 (has links)
The interest in the detail knowledge about elementary electronic processes during photogeneration of charge carriers, which allow achieving higher efficiency of organic solar cells, grows with advent of the commercial organic solar cells production. The thesis is focused on study of photogeneration of charge carriers in organic semiconductors, especially in -conjugated polymer materials. First part of the thesis summarized state of the art in studies of photogeneration of charge carriers in polymer solar cells. Subsequent experimental and results part are focused on study of polymeric solar cells prepared from electron donor polymers MDMO-PPV, Tg-PPV, PCDTBT and PCBTDPP and electron acceptor derivates of fullerenes PC60BM and PC70BM. Results of the thesis are divided in tree main parts: 1) study of charge transfer between electron donor and electron acceptor materials by optical methods, 2) study of charge transfer between electron donor and electron acceptor materials by optoelectrical methods and 3) development of organic solar cells on flexible substrates. The last part is focused largely on deposition methods of active materials thin layer.
