Development of concrete with high fly ash content and verification of durability in various environments
Ambruz, Pavel ; Voves, Jiří (referee) ; Hela, Rudolf (advisor)
This thesis contains two main parts: theoretical and experimental. The theoretical part deals with summarization knowledge of high-volume fly ash (HVFA) concretes. Among others, there are mentioned processes of producing of fly ash, characteristic features and resistance to aggressive environments of HVFA concretes. The theoretical part ends with a suitable example of practical application. In the practical part were tested properties of nine different mixtures containing 40%, 50% and 60% replacement by weight of the cement by fly ash. They were compared with the reference mixtures without fly ash addition. The main endpoints were long-term compressive strength, resistance to aggressive environments, the influence of fly ash on consistency, hydratation temperatures, water absorption and volume changes.

Formation of the Concept of energy self-sufficient of residential buildings
Hlavsa, Tomáš ; Horák, Petr (referee) ; Chlup, Jan (referee) ; Meixner, Miloslav (advisor)
Creating the concept of buildings is the primary task of architects, designers in the field of architecture and engineering. Although the basic requirements remain the same across time , possibilities of their solution are constantly evolving and changing. In addition, with the increasing globalization, in context of the housing and the architecture is expected new requirements go beyond the horizons of the interests of bouth investor and designer. Global view of each project and the evaluation of its traces left in our environment and society, although is much discussed but rarely taken into account or even just considered. In this context, we are witnessing the development of new trends of the concepts of buildings, consisting in the use of natural materials, in reducing the environmental burden of a surroundings, in reducing energy demands, or even in an effort to achieve energy independence thus trends, whose common denominator is sustainable construction, hence sustainable development in general. Feasibility of the creation of the concept of energy self-sufficient building doesn´t consist only in the precise solution of the assigned task from the perspective of the designer or investor, but also in finding such a solution which, even with using new trends and principles, will not go against the initial idea itself. The present instrument processed and presented in this dissertation has the ambition to move global view of the project into the perspective of a particular individual design process and in small way contribute to the creation of better projects from the perspective of sustainable development The term of energy self-sufficient buildings are not clearly defined. To work with them it was necessary to determine their basic definition that describes their diverse conceptual variations and allows precisely define the solution area. To correctly select the optimal solution in terms of sustainable development is necessary the assessment and mutual comparison since the beginning. As a basic tool for this assessment was used and partially modified SBTool, which is built on three basic pillars of sustainable development - SOCIAL - ENVIRONMENTAL - ECONOMIC. SBTool tries to determine the degree of left traces of the approach from the perspectives of these three aspects and evaluate the effectiveness of the selected solution. This tool allow to compare the different concepts for the same project among themselves, their parts but also various projects among each other. All of course with regard to the development of various aspects in the time.

Wooden buildings using natural thermal and acoustic insulation
Ambrožová, Elena ; Spáčilová, Jitka (referee) ; Myslín,, Jiří (referee) ; Solař,, Jaroslav (referee) ; Hirš, Jiří (referee) ; Spáčil, Miroslav (advisor)
Dissertation deals with the technical parameters of natural thermal insulation. In addition, there is a global trend in the construction of reducing energy consumption for heating, air conditioning, or with operating facilities in buildings and the use of perspective and efficient building materials with a negligible negative impact on the environment. Therefore, the attention not only professionals are increasingly turning to alternative materials, such as natural insulation, the material can be drawn from local sources and whose production is energy-saving and leaving a small ecological footprint. As part of the doctoral thesis were tested short term water absorption, measurements were made of the thermal conductivity and its change after the test short term water absorption. Was determined dependence of thermal conductivity on humidity and heat resistance was determined. Moreover a natural insulation applications in building construction with a comparison of the various technical parameters and environmental footprint. At the conclusion was made by acoustic insulation in timber construction and price analysis.

New town hall for the district Brno-North
Franců, Jan ; Pechman, Tomáš (referee) ; Sochor, Jan (advisor)
The project design a city town hall for Brno north on the site of today's military barracks. Classical symmetry of the composition of the original building dominates the space above the terrain configuration. The buildings are oriented towards the slope and determine the nature of space. In this constellation any classical building would disturb this order. The volume of the building must be very subtle to preserve the harmony of the original composition. The main volume of the building is located below the surface of the square, however, the building is open towards most exposed corner. Sloping slab fall line is aiming to the city center and Špilberk Castle. The inclination is only 8 degrees to allow safe movement and to preserve the original space. The building preserves the street lines of surrounding blocks, but sloped slab exceeds the corner across the street line to draw attention. Parts of the building, requiring daylight had to be placed above the ground, but to preserve the original space the new volume must be subtle.

Place of Sustainable Development
Křístková, Veronika ; Rudiš, Viktor (referee) ; Koleček, Ivan (advisor)
To create a sustainable place in a city. As a result of my work, I bring up this definition: First: a place with its own strong structure and character which would not be interchangeable with another one, but easy to recognize and easy for inhabitants to create the relation to. Second: a place which can easily change within, but without loosing its character. Third: a place you can enter inside and discover new connections and new dimensions, invisible from outside. Trying to apply these principles on a given locality – cargo train station Gare de Sebeillon in Lausanne, Switzerland. Space planning for the yard and reconversion of the hall.
