Ecotoxicity of mixed waste in Life Cycle Assessment
Lukáč, David ; Kočí, Vladimír (advisor) ; Burešová, Helena (referee)
Subject of the study is establishing ecotoxicity (in the form of EC50) and characterization factors (CF) of two real soil samples, contaminated by a mixture of heavy metals, by using terrestrial tests of ecotoxicity. The gained values are then compared to CF values nowadays used in life cycle assessment (LCA) studies and the differences are discussed. The heavy metals contents are assessed by sequential extraction with ICP-OES. To gain the EC50 values following organisms are used: enchytraeids Enchytraeus crypticus, collembolans Folsomia candida (determining inhibition of reproduction) and lettuce Lactuca sativa (determining inhibition of root growth). EC50 and CF values show higher ecotoxicity in the case of Vodárna sample than in the case of Rampa sample. A difference in CF assessment between the method of using terrestrial tests and mathematical method, which is used generally, is proved.

Added value of green roofs
Hrachovina, Vojtěch ; Žák,, Antonín (referee) ; Petříček, Tomáš (advisor)
Introduction is focused on analyze green roof like a part of buiding construction, when thesis assembly principles of right proposal green roof layers. Main part describes characteristic properties green roofs at global impact. We get some added values after comparison with classic roof types. Master thesis consists of survey of added values of green roofs in these categories: life cycle assessment, microclima, outdoor climate, water retention. End of thesis devote to psychological effect of green roofs include questionnare about relationship between czech society and green roofs.

Waste management system sustainability
Bravený, Adam ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
The thesis proposes a new approach to assess sustainability of waste management systems. In the first part current mixed municipal waste (MSW) management system of the Czech republic is reviewed and promising MSW treatment techniques are introduced. In the second part a summary of literature on Life Cycle Assessment (LCA) approach to assess sustainability of MSW systems is provided. A new sustainability assessment model is proposed by implementing LCA to a current tool called NERUDA used to optimize waste management costing. It is demonstrated how to connect these two concepts in order to aquire a powerful tool for sustainability assessment.

Building Life Cycle Costs
Bohadlová, Darina ; Marková,, Leonora (referee) ; Korytárová, Jana (advisor)
This diploma thesis deals with the life-cycle cost of the building for teaching and research. The theoretical part deals with the introduction of life-cycle cost method. A description ofdetermining life-cycle cost and procedure of processing. In the practical part of the budgetis prepared surveyed the building, which is divided into functional parts and the fixed costs of repair and reconstruction over the lifetime of the building. At the end of life are roughlydetermined the cost of demolition and waste removal. This whole process is summarized in the table, which sets the cost of operating the building throughout its life.

Využití metody hodnocení životního cyklu výrobků (LCA) v České republice: LCA - Příručka pro zpracovatele
Vysoká škola ekonomická v Praze, Fakulta národohospodářská, Katedra životního prostředí, Praha ; Tichá, Marie ; Remtová, Květa
Metoda LCA (Life-Cycle Assessment) je systematický normalizovaný postup, který slouží ke stanovení dopadu výrobku, činnosti nebo služby (obecně systému) na životní prostředí, a to od vzniku systému (získávání potřebných surovin z přírody pro jeho vznik, existenci) až do jeho konce, tj. do návratu odpadních látek zpět do přírody. Význam metody LCA spočívá především v komplexnosti provedeného posouzení. Vliv zkoumaného výrobku na životní prostředí není posuzován jen z hlediska jeho výroby nebo z hlediska jeho působení ve spotřební sféře, ale z hlediska jeho celé existence. V příručce je hlavní důraz kladen na pochopení podstaty metody a na provádění jednotlivých fází, z nichž se normalizovaný rámcový postup metody LCA skládá. jsou uváděny i jednotlivé ilustrační příklady. Stanovení cíle a rozsahu (I. fáze LCA). Inventarizační analýza (II. fáze LCA). Hodnocení dopadů životního cyklu (III. fáze LCA). Interpretace životního cyklu (IV. fáze LCA).
