Environmental solution of a house with a café in Zaječí
Medková, Tereza ; Uher, Pavel (referee) ; Rubina, Aleš (advisor)
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.
Controllable power supply for LED lighting
Morávek, Petr ; Pavlík, Michal (referee) ; Boušek, Jaroslav (advisor)
This thesis deals with the description of artificial light sources, that use light-emitting diodes for their operation. Further down, the parameters of LEDs and their emissions are detailed. The work follows with the characterization of principles of LED power regulation. In the practical section, an example of one of the possible LED light source topologies, is designed. The offered solution includes the options to manually and automatically regulate the chromaticity of emitted light. Functionality of the solution was verified experimentally.
Illumination with respect to biological functions
Němec, Jiří ; Štěpánek, Jaroslav (referee) ; Baxant, Petr (advisor)
The paper summarizes the basic light-technical parameters, the principles of visual and non-visual photoreceptions and the effects of light on the organism. Several chapters focus on the mechanism by which light affects hormone levels and the circadian rhytm of the organism. In relation to the lighting system, the impact of electromagnetic radiation, associated with the controls, on the body is also considered. Briefly described are systems based on smart LED light sources or smart switches. The result of the thesis is to choose the solution that best suits the requirements of the contracting authority.
A light source with variable intensity
Koždoň, Jakub ; Mojrová, Barbora (referee) ; Boušek, Jaroslav (advisor)
This work is focused on description how the light impact human live, description of light sources and finally design and construction of light source with adjustable colour temperature and luminous flux. In introduction is mentioned the process of vision and how the light impact humans. In next part is characterization of currently used light sources, their construction, properties, benefits and drawback with their main parameters. Important part of this chapter is more extensive description of light emitting diodes with their operational parameters. The last two parts is focused on design and measuring the parameters of created light source with adjustable colour temperature and luminous flux and evaluating the results.
