Academic literature on the topic 'Energeticky úsporné stavby'

The doctoral thesis pays attention to the system approach to the nonstationary computational modelling of heat transfer for energy saving buildings. The created computational tool supports the optimization of selected design parameters.

Human efforts to increase their comfort rise in density of population in congested city areas, rapid growth of traffic and electric smog created due to constantly transforming communication technologies all resulted in an increase of stress in the immediate human environment. All of this, along with frequent reports about changes in global climate, gradually contributes to an alteration of thinking of the whole society, which is forced to face the consequences of economic damages caused by climatic changes. If we want to tenably assert adequate economic and social living conditions, we have to approach the natural environment in a more profound way. In accordance with the trend of substantional development for the purpose of enhancement of the quality of the living environment in the field of building industry, it is logical to concentrate on buildings, which are conceptually focused on saving of the energy. That is on energy-efficient houses. Pathway to sustainable building is not based on discovering one or several multipurpose technological solutions, but on usage of new designing principles, new materials and methods of processing them as well as new techniques of construction. For an effective creation of a building concept it is essential to have that kind of device which quickly responds to changes performed on a design, enables an easier work on variants and produces the most accurate results. Consistent application of energy optimizing methods is necessary particularly for designs of energy saving houses. Beginning efficient building design is the most “abstract factor of concept linked with very uncertain inputs,” because a lot of parameters in that moment is still unknown. Many mutually connected factors are invoked during designing passive house e.g. trajectory of the sun and the shielding effect of the surroundings, the aspect of sunlight and interior lighting, power quality construction, etc. Currently, the architect has no choice, he can use only well-known precepts, such as large windows are facing the South not the North. Unfortunately this "empirical formula" for the design of a real passive house is not enough. And yet the first draft of the house is most affected by not only its shape, form, but user´s comfortable, cost, feasibility and future energy behavior of buildings and related operating costs of the house too. It is obvious that this stage should not be underestimated, because “minor variation of the initial inputs greatly influence the outcomes.” With this reasoning, the work focuses on early stage design decision, i.e. the architectural concept of a passive house (an idea, vision). Therefore the aim of this work is to simplify the issue into understandable form, i.e. the creation of relatively simple and illustrative sketches, which generalize the issue satisfactorily, show the individual parameters (glazing, shading, shape, size, etc.) and change need of heat for heating passive house. The results of the work will be useful when the architect picks up the pencil and starts to think about his future house. At this point, he will have on hand sketches, which give him an idea and streamline his further design. Therefore the main goal is to create new outcomes and identify energy behaviour of buildings with a computational tool. This research works with virtual idealized mathematical model in the software PHPP 2007 CZ and uses "phenomenon" of parametric equations and sensitivity analysis.

This master thesis is focused on energy audit of a civil building in regards of the state legislati-on. The purpose of this energy audit is to compare energy properties of this civil building and also to design at least two variations of energy savíng solutions. These solutions are designed regarding an economic and ecological focus of the audit and the variations of energy savings.

The diploma thesis deals with the energy audit of the civil building according to the valid legislation of the Czech Republic. The theoretical part describes photovoltaics. In the calculation section is performed an analysis energy consumption for the initial state and new state. In the last part, the energy audit itself is elaborated. Saving measures have been proposed, two variants, including the recommendations of one of them.

The aim of the thesis is the energy rating of buildings. The introduction included the issues of the topic, including normative and legislative regulations, process energy performance certificates along with energy audits for residential building. The object is evaluated in terms of energy, economic and environmental. Within the energy audit was designed and evaluated austerity measures.

The first section of this thesis describes possible energy savings in family houses. Subsequently, possible energy savings are applied to, and a system revision is presented for, an office building, along with a calculation of the return on investment for the described variant based on notice 480/2012 Sb. The final section focuses on the measurement of the indoor environment at an administrative building (CO2, air temperature, relative humidity) and their assessment according to the current legislation.

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.

This diploma thesis deals with the impact of thermal insulation on expenses relateted to the operation of the weekend house. Theoretical part describes options of thermal insulation systems, insulation methodes, describes structural prices and costs. Practical part of this thesis describes heat costs on specific weekend house situated in Karlovy Vary region. Thermal insulations are designed in three different variants. Calculation of costs of every designed insulation systém is included in this thesis. In next part of thesis is calculated return of investment for every designed solution. In conclusion of the diploma thesis are compared impacts of thermal insulation on expenses ralated to the operation of the weekend house.

Designed children´s sanatorium is situated on the cadastral area of Ostrova u Macochy town, in the protected area of Moravsky Kras. The architecture of this building fits in the surroundings of the landscape and respects its features. The building main attributes are its south-facing slope, the compositional construction from prefabricated reinforced concrete structure and perimeter sandwich structure, as well as the massive insulation. Thanks to these characteristics, it is classified as energy-efficient building. These eight buildings, interconnected by the massive colonnade in its middle axis, force the user to take advantage of all its energy-efficient advantages.

This is the proposal of the new utilization of the former recreational centre, which is situated in the beautiful surrounding of the Brno lake. It has been abandoned for many years and is suffering from decay. It has been built in the 1970's for the demand of the Socialistic youth union (remark: the youth organisation of the communist's party). There were held international political conventions and educational sojourns for the students of high schools and universities. The new utilization will be analogous. Only the communist's ideals will be replaced with the ideals of today's democratical society – especially friendly relations between mankind and environment. There will be created the environmental educational centre with the meeting spaces, conference hall and accomodation. The universal concept enables the usage of the facility also for the international students' workshops, training courses, teambuilding events etc. The ecological educational centre primarily makes the good example and is the live educational requisite. Thanks to the concept of the original facility is very convenient the refurbishment to the standard of the energetically passive building, which consists from the natural materials and utilizes renewable energy resources. Because of the very poor technical condition and devastation of the building will be re-used only basement and steel framework. This solution is more economical than the demolition and following new construction. The construction core of the building is almost for free. However, only if we make minimal changes in the framework and we preserve the original building's shape. On the steel framework will be created the new lightweight housing, which will be made from wood, straw pannels and filled with the cannabis thermal insulation. Almost all the roofs will be covered with the photovoltaic foils and the heat source will be air heat pump. The area is very pleasant place to stay. It's full of sunshine all day long and offers very beautiful view of the lake. The main building and bungalows profit of the attractive views. All the former recreational area has was designed to make the people meeting together and to provide the freedom of move and wide variety of activities. However, the rooms and bungalows provide the highest privacy. The inside and outside of the buildings are shading into each other. All the recreational ground – in exterior and interior – is full of liveliness, in the opposite of the rooms, which are the private islands. This aspect, which is present in the former concept from the 1970's, is to be preserved. The former hotel building is distinguished by the quality architectural concept, above-average in the age of origin. It is thanks to the dynamically balanced composition – inspirative today too, and visually interesting interior design of the meeting spaces. This proposal attempts to continue in this qualities. The ground is enriched with the relaxational spaces and the outside gym path. In the opposite of the original state the area is open to the public and is utilized as a park for leisure activities.
