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...

Life cycle assessment of buildings
Mrkvičková, Kristýna ; Kočí, Vladimír (advisor) ; Hák, Tomáš (referee)
This bachelor thesis is focused on life cycle assessment of building construction. All impacts will be modeled on residential house in professional LCA software. Every single component of the building was evaluated with regard to their impact on enviroment. The output list each category of indicators and evaluation of the impact. It shows which environmental categories are most affected by building and where it would be useful to optimizme it. The family house presented by the typical new building was chosen for evaluation process. The product system was simulated by the GaBi 4 software tool, then it was evaluated using the impact categories of the CML 2001 - Nov. 09 characterization model. The theoretical part deals with the LCA methodology, explains the different stages and describes categories of impact. Furthermore, the global trends are discussed in terms of assessing the building lifecycle. At the end, the LCA study has shown that the biggest influence on the environment is caused by the service life of a product's lifecycle and water treatment contributes the most on this result.

Management of architecture competitions in Austria and the Czech Republic with regard to the importance of buildings' sustainability criteria
Doušová, Aleška ; Tyslová, Irena (advisor) ; Prokůpek, Marek (referee)
This thesis analyses issues with the management of architectural competitions in the Czech Republic and Austria. The first part focuses on the contest participants and methods for public procurement in architecture in the Czech Republic, and analyses the critical parts of the competition. This is followed by a chapter dedicated to Austrias legal code on architectural competitions. The theoretical part concludes with a description of the current situation with regard to the sustainability of buildings and to their management in architectural competitions in the Czech Republic and Austria. The final chapters compare the process of building retirement homes in Austria and the Czech Republic. The projects compare the announcement of the architectural competition, the management of the competition and the overall process. Both projects are compared for the implementation of sustainability requirements. The aim of my paper is to present and compare architectural competitions in the Czech Republic and Austria, with an analysis of how much the sustainability of buildings is taken into account within the competition rules. This thesis was completed using an analysis of available materials, a description of the situation and a comparative study.
