Ecological evaluation and labeling of electrical products
Kantorová, Aneta ; Šteffan, Pavel (referee) ; Szendiuch, Ivan (advisor)
This bachelor thesis is focused on the possibilities of reducing the negative effects of electrical products on the environment. After a general description of the current state, including activities aimed at awarding environmental labels, attention is focused on the possibilities of ecological evaluation of electrical products. Legislation according to the standards of the ISO 14020 series is applied for this that are focused on three possibilities of awarding eco-labels. In the practical part a procedure for awarding the ECO mark according to the ISO 14021 standard is proposed. This could be granted by the manufacturers themselves on compliance with the prescribed conditions as in the case of the declaration of conformity for the CE marking.

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.

Volumetric Method for the Determining kg CO2 eq. and Energy Requirements for the Production of Power Tools at an Early Stage of Product Design
Sovják, Richard ; Sobotová,, Lydia (referee) ; Grall, Günter (referee) ; Křenek, Ladislav (advisor)
Emise kg CO2 eq. vznikají v různých fázích životního cyklu výrobku a mají významný vliv na globální oteplování. K posouzení těchto negativních vlivů slouží metoda Life Cycle Assessment (LCA), která umožňuje určit uhlíkovou stopu, energetické nároky na výrobu materiálů, výrobní procesy, transport, užití a konec životního cyklu. Tyto analýzy jsou časově náročné, nákladné na zaškolení a vyžadují hmotnostní a materiálové charakteristiky výrobků. Navržená metoda VEME (Objemová hodnotící metoda ecodesignu) využívá objemových vlastností výrobku a jeho strukturálního a materiálového složení. Pro dosažení cíle bylo analyzováno 134 kusů nářadí (vyrobeno 1989 až 2018) se začleněním do 10 typových skupin podle druhu nářadí. 3D skenováním byl určen objem výrobku s následnou materiálovou analýzou a po té byla použita metoda Oil Point Method (OPM), která je založena na LCA. Nářadí bylo posuzováno ve třech možných variantách konce životního cyklu (skládkování, spalování a recyklace 90 %). Ze získaných dat byla provedena simulace Monte Carlo pro každý vzorek nářadí n = 1 000 s 95% spolehlivostí. Byly stanoveny rovnice pro určení energetických požadavků na výrobu nářadí, emisí kg CO2 eq. (pro 11 světových zemí), údajů na balení a transport zboží. S 90% recyklací je možné uspořit až 32,4 % energie oproti skládkování. Ze všech 134 vzorků bylo 9,7 %, u kterých byla recyklace až o 6,2 % energeticky náročnější než skládkování. Důvodem jsou vysoké energetické nároky na recyklace materiálů. Nová metoda najde využití při navrhování výrobků v průmyslovém designu, ale i v oblastech ekonomického zhodnocení způsobu a místa výroby. Lze jej využít i pro rozšíření energetického štítkování výrobků, které by zahrnovalo energetickou náročnost výroby, transport a balení.

The influence of energy mix on environmental impacts of waste management
Dočekalová, Veronika ; Kočí, Vladimír (advisor) ; Trecáková, Tatiana (referee)
This paper presents energy mix of Czech Republic and its effects on environmental impacts of waste management. Three technologies: landfilling without energy recovery and landfilling and incineration with energy recovery are assessed using LCA. Results for 1 t of mixed municipal waste are compared in 9 impact categories: abiotic depletion, acidification, eutrophication, global warming, ozone layer depletion, photochemical ozone creation, human toxicity, terrestrial ecotoxicity, freshwater ecotoxicity. Landfilling without energy recovery was evaluated as the most harmful technology to the environment, incineration as the most environmentally-friendly one. The use of Czech energy mix made impacts of the energy recovery technologies look lower, contrary to burdens of landfill without energy recovery that resulted higher. The influence of energy mix composition change is discussed further.

LCA of NATM tunnel stamping method
Pokorná, Alice ; Kočí, Vladimír (advisor) ; Trecáková, Tatiana (referee)
The aim of this thesis was to evaluate the environmental impacts of NATM tunnelling method using the assembly of LCA studies. Construction sector still has large potential for advancement, and therefore is a subject of interest for also for LCA studies. Underground constructions applies more with growing demands for space in infrastructure. If sustainable growth in construction is desired, it's important to have an idea about the environmental impacts of this sector. Sustainable growth requires methods and tools for measurement and comparison of impacts of human activities on the environment. These tools are provided by LCA studies, which also allow a proactive approach. The advantage of LCA is a preview of the entire life cycle of the product, so there is no shifting of problems between the individual stages of the product's life cycle. LCA study of cradle-to-gate type was selected to evaluate New Austrian tunnelling method. LCA study was done for one tunnel, length 850m with cross-section surface of 13,46m2 excavated by the NATM method, realized over the course of 18 months. GaBi 6 software tool was used for making of this study. Results show that the most important emission sources of NATM tunnelling method are production of cement, dumping of excavated material, production of reinforcing steel...
