Environmental Impact Assessment for Chosen Plastic Molding Technology
Dufková, Hana ; Kotek, Luboš (referee) ; Krbalová, Maria (advisor)
This diploma thesis deals with assessment of environmental load by selected plastic molding technology. The first part is focused on the ecological legislation in the field of mechanical engineering, which also includes the production of plastics, and describes various methodologies for assessing the environmental load. Another chapter is an overview of polymers and their properties as well as the possibilities of plastics processing with description of individual types of production methods. The practical part of this work describes the composition of the produced piece and the injection molding process of plastic production. Its two methods (direct gating and hot sprue method) are analyzed and then the environmental load evaluation is performed using the LCA method – product life cycle assessment. The environmental load of both production methods is assessed.

Life cycle assessment of municipal waste
Vlach, Josef ; Slavík, Jan (referee) ; Jícha, Jaroslav (advisor)
The aim of this study is to present methodology life cycle (LCA) and Life Cycle Assessment of disposal the municipal solid waste chain. There is described the procedure of generation of the LCA studies according to the standards ČSN EN ISO 14 040 and ČSN EN ISO 14 044 in the first and second part. In the third part of this diploma there are described LCA analyses that have already been created. The software GEMIS (Global Emission Model for Integrated System) is described in the fourth part. The computer model GEMIS has been used as a calculation tool in this study. The fifth part of this study includes waste management and different kinds of disposal municipal solid waste. In this part is describe basic data about landfilling and incieration. There is shown LCA analysis of disposal municipial solid waste in the sixth part. Data processing was carried out by means of the software GEMIS 4.3. The results were interpreted for incineration and landfilling. Finally there is mentioned results for 1 TJ different elektrical energize to.

Environmental Impact Assessment for Chosen product
Durda, Tomáš ; Řezníčková, Hana (referee) ; Krbalová, Maria (advisor)
The Master´s thesis is structurally divided into the theoretical and practical part. In the theoretical part, the author describes current global environmental issues and the impact of the industry on the environment. The current state of the environmental legislation in mechanical engineering, environmental management systems, and methodologies of an environmental impact assessment are described. The practical part deals with the environmental burden of the snowboard production process according to the LCA method. Life cycle inventory is performed to evaluate individual materials whose production is the most environmentally damaging. At the last stage, possible measures are proposed to reduce the environmental burden.

Environmental Impact Assessment of Manufacturing Abrasion Resistant Coatings with Magnetron Sputtering
Krobauer, Jakub ; Holub, Martin (referee) ; Kocmanová, Alena (advisor)
This thesis is focused on the environmental impact assesment of the manufacturing process of cutting tool coatings. Described are current environmental problems and duties of companies affecting the environment. There is a description of methods used in environmental management, one of which is the LCA method. This method is then used to compare environmental impacts of TiN and AlTiN coatings. The thesis describes manufacturing process of these coatings and evaluates environmental impacts for both coatings. These results are then compared and conclusions and recommendations are made.

Determination of carbon footprint in relation to the production unit of the budget indicator
Šebestová, Michaela ; Kocourková, Gabriela (referee) ; Krejza, Zdeněk (advisor)
The presented diploma thesis analyses the possibilities of determining the carbon footprint in relation to the production unit of the budget indicator. The theoretical part of the thesis describes the basic concepts associated with the carbon footprint and construction industry. The aim of this thesis is to quantify the carbon footprint of construction process, mainly during the production phase, and to compare the carbon footprint of objects of different production technology. The main output is the determination of an average carbon footprint converted to a unit of the budget indicator.

Office building JMC Brno
Honzl, Jakub ; Krupica, Roman (referee) ; Bantová, Sylva (advisor)
The aim of this master’s thesis is to elaborate the project documentation of an office building in Brno with nearly zero energy consumption. This building consists of 2 parts. First part is a two-storey building with a basement. In the basement are storages and mechanical rooms. On the first floor is a cafe and sanitary facilities. On the second floor is an open-space, two meeting rooms and a manager's office. Second part of the building are garages that has one above ground floor and one underground floor. The structural system of the building is RC frame, and it stands on grillage foundation. The office part is roofed with warm flat roof and external walls are insulated with insulating panels made of mineral wool. The garage part is roofed with green roof. This master’s thesis consists of 3 parts. First one processes the application for a building permit. Second part deals with technical equipment of the building namely design of boiler, ventilation and photovoltaic panels. Third part deals with life cycle assessment of different composition of floors. It compares these floors and evaluates them. And in the end the floor which has the best results is implemented back into the project.

(MATERIAL) – CONSCIOUS DESIGN
Filípková, Valentýna ; Václavková, Maria Nina (referee) ; Tobola, Ondřej (advisor)
The online platform consciousdesign.cz, created as the output of the thesis, provides sources for possible conscious approaches to design. It consists of a database of innovative materials, research texts, related links and interviews with designers, material specialists, scientists and technologists. The website can serve as a starting point for students and designers who are interested in current possibilities and new ways leading to design that is responsible to nature and humans.

Coworking office building
Borková, Sabina ; Sochorová,, Zuzana (referee) ; Struhala, Karel (advisor)
The aim of the thesis is to design a detached two-storey office building with green roof in Pardubice. The thesis has three parts. First part presents architectural and structural designs. The building has concrete strips. The vertical loadbearing structures are designed from ceramic blocks. The envelope wall is insulated with mineral wool ETICS. The horizontal structures are designed from the prestressed Spiroll floor panels. The floors are connected by prefabricated reinforced concrete staircase and an elevator. The walls around the elevator shaft are designed from reinforced concrete. The building is assessed in terms of thermal technical requirements, acoustics, daylighting and Energy Performance Certificate. The second part proposes the design of selected building services. This part includes the design of artificial lighting, rainwater management, the design of photovoltaics, heating, mechanical ventilation and cooling. The building is connected to local district heating grid. It is cooled by VRF units on the roof and ventilation units in individual rooms. There are 42 photovoltaic panels on the roof with east and west orientation. The third part assesses the life cycle assessment of the structures. In this part, six different compositions of floor structure are assessed. The best composition is used in the design of the building. The third part of the thesis deals with the life cycle assessment of the structure. In this part, six different compositions of flat vegetated roofs are assessed. These compositions differ from each other in the type of waterproofing material and the type of the gradient layer. A roof area of 1 m2 with a heat transfer coefficient of U = 0.148 W/ (m2.K) was chosen as the functional unit for the LCA. One Click LCA software was used in the calculations. A life cycle was created for each component, including the different phases and modules defined in EN 15978. The following programs were used for the thesis: AutoCAD 2022, ArchiCAD 25, Building Designe, Hluk +, FIRE–NX, DEKSOFT, One Click LCA, Microsoft Word, Microsoft Excel, Microsoft PowerPoint, Adobe Acrobat.
