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.

Cost analysis of passive houses and houses with zero energy demand
Gregovská, Kateřina ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The bachelor's thesis deals with the envelope structures of an existing family house, which is in a passive standard. The constructions being compared are therefore peripheral, floor and roof. The subject of this work is whether the proposed structure composition is effective, both in terms of heat transfer coefficient and in construction costs and speed. Alternatively, find a better possible variant of thermal insulation for already designed compositions of envelope structures. The work therefore compares different types and thicknesses of thermal insulation. The values of heat transfer coefficient, cost intensity and time intensity were used for comparison.

Economic Assessment of the Construction of Passive and Active Houses
Ondra, Filip ; Komosná, Milada (referee) ; Hrdlička, Tomáš (advisor)
This diploma thesis examines the economics of use of technologies linked with low-energy, passive, and active house construction which is presently very often a topic of interest. The goal of the thesis is to evaluate economic effectivity of additional investment into construction materials leading to reduction of heating requirements of the evaluated family house. Furthermore, economics of the use of advanced technologies of ventilation, different heat sources and photovoltaic power plant are assessed. The result is a complex evaluation of different alternatives of the house which makes this thesis helpful in answering the question whether these additional investments will pay off.

Non-standard family house
Wiesner, Jakub ; Jelínek, Petr (referee) ; Rusinová, Marie (advisor)
Aim of the thesis was to design Non-standard family house and work out documentation for construction realization. Designed building is two-storey family house for permanent residence of 4-6 persons with floor area 224m2. Non-standard solution is design of passive timber structure founded on reinforced concrete slab lying on thermal insulation pillow formed by foam glass. Using of natural materials as far as possible and creation of healthy inner micro-climate is very Non-standard too. The buiding has also very non-standard shape with combination of oblique and planar walls. Thesis itself consists of 2 main parts. First part is description of construction in technical report. Second part is main project documentation including calculations.

Assessment of the economic efficiency of a passive house
Mašková, Pavla ; Comorek,, Martin (referee) ; Kocourková, Gabriela (advisor)
The Master thesis is focused on rating the specifics of passive houses and assessment whether the energy savings in the operation of passive house will cover the increased cost of construction. The theoretical part deals with the history and development of passive houses, application of natural materials, sustainable resources of energy and indicators for the evaluation of economic efficiency. The practical part describes passive and standard house. On the standard house, there is processed financial plan. Reference objects are compared, followed by evaluation of the return on the additional costs of the passive house.

Construction details of buildings evaluation from energy demand point of view
Císař, Milan ; Šikula, Ondřej (referee) ; Adam, Pavel (advisor)
Theoretical part of Diploma thesis deals with issues about thermal bridges and thermal connections in building structures. The Calculating part focused on the family houses with a low heat use. The results of this part are energy and financial evaluations of family house. The last part deals with the using of computer technology in engineering practice. These chapters devote about computer modeling an assembly details of passive house and family house after reconstruction (the dates of family house after reconstruction are compared with the results from experimental measurements). The last section of this Diploma thesis solves dynamic modelling of particular passive house in simulation program called Trnsys.

Architectural expression of residential buildings in energy-efficient housing
Gerö, Jiří ; Peřinková, Martina (referee) ; Wahla, Ivan (referee) ; Ing.arch.Henrich Pifko (referee) ; Meixner, Miloslav (advisor)
These days create an enormous pressure on energy savings because of their high prices. For future it is obvious that their prices will grow. Not only the representatives of European Union realize this fact, but basicaly common people who run their houses and pay the bills. For this reason low - energy houses respectively passive houses are in the limelight. Reasons of economy should not be the only criterion of quality, but its integral part, one of several components. Energy efficient housing is a response in architecture and building to turbulent global warming. The aim of the work is try to specify how to conceive an efficient building with respect to its architectural quality in the contect of directions coming from European Union and which should be implemented soon in the Czech republic. Will zero house become driving force of architecture in Europe in 21st century? The result of the work will be useful in orientation how to conceive an efficient house with respect to its aesthetical quality.

Business Plan - Development Project of the Construction of Homes for the Elderly
Staňa, Marek ; Mládek, Josef (referee) ; Heralecký, Tomáš (advisor)
This bachelor thesis focuses on the development project, the construction of low-energy, passive houses for the elderly. The work compares and assesses the effectiveness of the investments from the investor's perspective, but also from the perspective of macroeconomics. The saving impact on the environment is also considered. The attention is also given to the used construction materials in terms of health and comfort of future customers of these buildings.
