Energy assessment of buildings
Velísková, Eva ; Maurerová, Lenka (referee) ; Hirš, Jiří (advisor)
The master’s thesis deals with energy assessment of buildings according to a current valid legislature. In the first part the energy assessments problems are solved. The next part solves the energy concept of the educational building, Pavilion P4, AdMaS centre of Faculty of Civil Engineering of BUT, in the form of project documentation. In the part of thesis there is a simulation characterizing dynamic behavior of building. The thesis point is the evaluation of energy balance and a draft of measures leading to the power consumption decrease.

Energy-efficient house for doctors and nurses in the city of Kroměříž.
Dvořák, Petr ; Blasinski, Petr (referee) ; Rubinová, Olga (advisor)
The aim of my thesis is to design the project documentation of an energy-efficient house for doctors and nurses, located near the hospital in Kroměříž. The work is divided into three parts. The first part focuses on the architectural and construction design of the building. The second part deals with the design of the technical equipment of the building and its layout. The third part deals with the design and comparison of different cooling sources. The building is a two-storey building with a flat, vegetated roof and its design is in the building permit stage. On the ground floor there is a bistro, a dining room with food preparation, technical rooms and 3 apartments. On the second floor there are 9 apartments and a lounge. In the middle of the building there is a circulation area with a staircase, a glass elevator and a large skylight that illuminates the whole area. Heating is provided by a gas condensing boiler. Ventilation is provided by three air handling units. A hybrid cooling system with heat recuperation from the refrigerant is designed. For partial electricity demand, 62 photovoltaic panels are installed on the roof of the building. The third part deals with the design of alternative cooling solutions for the building. Multi split, VRV and water cooling system with roof top chiller are proposed in addition to the already designed hybrid system. These four alternatives are compared with each other and the most suitable option is then designed.

Computer-Controlled Planting
Pospíšil, Jan ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This work is focused on the issue of plant cultivation in domestic conditions. We focused on the automation of the growbox using the Wemos D1 R32 ESP32 board, which then consists of the design and implementation of three parts of the solution, i.e. the growbox itself, including the sensors needed to maintain ideal conditions for the plant being grown, the user applications, for interpreting the values and the configuration of the growbox. Application to collect data from growbox, for later analysis. The solution includes the creation of a demonstration growbox, software for all parts and comparison with available home growing systems.

Deferred Shading
Starý, Petr ; Švub, Miroslav (referee) ; Jošth, Radovan (advisor)
Work deals with design and implementation a tutorial for demonstration deferred shading technique and its possibilities. It explains lighting and shading principles in intuitive and interactive way. Deferred shading is a technique which determines pixel color after the geometry rasterization of the entire scene. In other words the processing of geometry does not interfere with the shading process.

Project Documentation of Electrical Wiring for Comercial Building
Vondráček, David ; Bátora, Branislav (referee) ; Mastný, Petr (advisor)
This bachelor thesis deals with the creation of electrical documentation for a commercial building. It aims to introduce theoretical problems of electrical design in general and the processing of implementation project for a woodworking workshop. The theoretical part of the thesis is mainly devoted to important findings and normative requirements for high-current, low-current distributions, and a draft of external and internal lighting protection. The practical part of the thesis deals with the processing of the implementation project of electrical drawing and text parts for a woodworking workshop. The project documentation includes the preparation of a technical report, the determination of the protocol on external influences, a draft of socket and light circuits, including lighting calculation, complete lighting protection, and risk management, electronic fire system, and a draft of the main and the sub-switchboard of the building.

Hierarchical Techniques in Lighting Computation
Ligmajer, Jiří ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This master thesis deals with description of hierarchical techniques in global lighting computation. Here is explaining the importance of hierarchical techniques in lighting computation and shows method, how to use these hierarchical techniques in realtime radiosity and its extension to dynamic area lighting. These two techniques are described in detail in the first part of this project. In the other part is desing and implementation of application for dynamic area lighting computation.

Modern LED luminaire concept for road lighting
Krejčí, Miroslav ; Kovářová, Klára (referee) ; Novotný, Jan (advisor)
This thesis deals with design of optical system for road lighting luminaire. In the beginning the basic photometric quantities and assessment methodology for requirements of lighting class M are described. The next step is the programming of algorithm which evaluates the road lighting requirements using few boundary conditions. The input of the algorithm is also luminous intensity (power emitted in a particular direction). By the turning the algorithm over, it is possible to evaluate the luminous intensity from the road lighting requirements. Those luminous intensities are used in the process of modification of optical lens. The ray tracing of modified models of lenses was performed to obtain the tables of luminous intensity. The values of luminous intensity are verified in the same algorithm. Finally, the comparison of results was made including several luminaires out there.
