Modelling and Simulation of Outdoor Lighting in Technicka 12 Area
Charvát, Kryštof ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
The work focuses on modeling and simulating outdoor lighting in the T12 area and working with lighting computational programs. The aim is to optimize the lighting system with respect to the specific requirements of the environment. Outdoor lighting plays a key role in shaping a safe, efficient, and aesthetically pleasing environment, thus it is important to use modeling and simulation methods to achieve optimal results. The work focuses on minimizing light pollution through accurate calculations without over dimensioning lighting and using appropriate luminaires, ensuring comfort for users of the T12 area, utilizing computational simulations, and photometric analysis. The results of this work will provide the basis for an efficient lighting solution for the T12 area.

Parking house as energy source
Novotný, Zdeněk ; Baxant, Petr (referee) ; Paar, Martin (advisor)
The bachelor’s thesis deals with the analysis of the use of selected parking houses for energy utilization. The introductory part is devoted to Vehicle-to-Grid (V2G) technology and concepts of parking lots proposed for energy purposes that enable the use of the technology. The theoretical part also includes the basic principle and implementation of wireless charging of electric vehicles, an overview of fast chargers and in the last part parking in Brno is presented. The practical part contains a comparison of 4 possible scenarios in which there was a gradual increase of individual charging stations. The output of each scenario is then the discharge and charging capacity that each parking house could provide.

Combined Heat and Biogas Production Using Bioreactor
Brachetka, Jan ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The bachelor's thesis deals with the use of anaerobic digestion in households to process biological waste and produce biogas. The goal of this work is to design a small-scale household anaerobic biodigester which, thanks to the possibility of continuous feeding with fresh material, will be capable of uninterrupted operation and biogas generation. The introduction defines the principle of aerobic digestion. The main part of the theoretical analysis is devoted to the description of anaerobic digestion and the factors that condition its formation. The basic properties and composition of biogas, as well as the types of household bioreactors, are also described here. Subsequently, the thesis focuses mainly on the design and construction of a household bioreactor, its commissioning, and evaluation of its energy balance.

Smart Solar Luminaire
Patera, Jan ; Novák, Filip (referee) ; Baxant, Petr (advisor)
This diploma thesis deals with designs, constructions, measurement of light technical parameters and energy consumption on a test prototype of a smart solar light fixture. The goal of the work was to create a survey of solar-powered lighting fixtures and to determine the potential of solar energy in the Czech Republic. Furthermore, find out and use methods for saving electrical energy depending on its stored amount and the need for lighting. The practical part is focused on the actual design, construction and measurement on the manufactured prototype of the light fixture. The algorithm used for changing the substitute chromaticity temperature during the day and the application for controlling the light fixture are described here. The measured values of light technical and electrical quantities are listed here. In the last part, the shortcomings of the prototype and possible suggestions for its improvement are presented.

Evaluation of possibility of modifying selected part of public lighting network for EV charging
Hýsek, David ; Vrána, Michal (referee) ; Baxant, Petr (advisor)
The master thesis deals with the concept of smart cities in the context of motivation for the use of the synergy of public lighting network and charging points. The thesis provides an overview of projects from the Czech Republic and abroad focusing on the adaptation of the urban public lighting network for charging electric vehicles. Different variants of charging station installations and their management are discussed. Another important topic is the selection of a suitable location for charging stations and the concept of synergistic connection of these stations with the existing public lighting network. The thesis proposes scenarios for using the existing public lighting network for charging electric vehicles and scenarios for bringing a parallel cable to this network in selected Brno locations. The aim is to optimize the efficiency and performance of the public lighting network and at the same time provide a charging infrastructure for electric vehicles. The results of the thesis represent a valuable contribution to urban planning and the development of smart cities that focus on sustainable and environmentally friendly mobility. The synergy between the public lighting network and charging points represents a potential for efficient use of infrastructure in the urban environment while contributing to the reduction of greenhouse gas emissions.

The measurement of melanopic quantities in indoor spaces with the luminance analyser LDA - LumiDISP
Siegel, Josef ; Baxant, Petr (referee) ; Motyčka, Martin (advisor)
This thesis focuses on measuring melanopic quantities in indoor spaces and their impact on individuals and their circadian rhythms. Melanopic quantities are specific parameters of light that influence biological responses and physiological processes in our bodies. To measure these quantities, a photometric analyzer is utilized, enabling the quantification of spectral components of light. It also evaluates the melanopic contributions of various lighting sources, such as LED fixtures, incandescent bulbs, or natural daylight.

Creation of Knowledge Database for Lighting Technology with the Possibility of Expert Query Processing
Krbal, Michal ; Sokanský, Karel (referee) ; Gašparovský, Dionýz (referee) ; Baxant, Petr (advisor)
This presented thesis is focused on the complex description of creation the database system for the lighting. The important static and dynamic parameters of light sources and luminaires are listed in the first part of thesis. These parameters are complemented by the measured values and their relationships. The next chapters of thesis are focused to description of obtained parameters, structural design, historical and expected development of individual representatives of light sources. In the following sections are described current state of used data formats of luminaires and the possibilities for describing of light sources. The database systems are created as a result of this thesis. These databases are used for collecting, sorting, searching and sophisticate comparison of the parameters of light sources and luminaires.
