Railings are a safety feature in buildings. They should prevent the fall of people. Their requirements are not only architectural and aesthetic, but also of mechanical resistance and stability. The current designs for the construction of railings include their anchoring to adjacent structures, which have the same requirements as the very structure of the railings. The tests on heat pumps are connected to an article on the tests of solar collectors. The basic operating principles of a heat pump is that it gathers heat from the surrounding environment and then transfers it to a higher temperature level and supplies to according the whether it will be used for heating or hot water. The advantage over collectors is that it works even if the sun is not shining.

This article aims to introduce methods and tools to assess the costs during the operational phase of the life cycle of buildings. Determining the life cycle cost of buildings is an important part of every construction project and a preliminary determination of costs in the operational phase life cycle contributes to the sustainability of future building.

ETICS for buildings is a key modification to reduce their energy consumption. Where and under what conditions it is still possible to use flammable thermal insulator, or with such modifications and where it is already necessary nonflammable insulator? Fire standards define different requirements for thermal insulation of new buildings from the requirements for additional insulation of older existing buildings for which they are allowed a certain structural exceptions.

The owners of houses in the Czech Republic, in which many flats share common central heating system, must fulfill new legal liability: “to equip the heating system in the building with the devices that regulate and register the delivery of heat to the end users, in the extent defined in an implementary regulation”. According to the law, they have to do so by end of year 2014. The problems are that neither the devices are further specified in the law, nor the implementary regulation exists. The most frequent hypothesis about this duty is that one should install the so-called indicators of heating expenses. It might be valid, but it goes far beyond the legal requirements: As a side effect, it introduces certain method of the expenses accounting. This article presents and justifies an alternative: The liability can be fulfilled by installation of thermostatic valves on the heating bodies.

The emergence of the working colonies of coffee plantations in Nicaragua is one of the most interesting construction projects in which is utilized the “Grow Your Own House” theory. In 2008, a Spanish design office developed a project based on environmental principles with the use of local material resources and subsequently there was built a self-sufficient colony Santa Emilia for coffee plantation workers in Matgapalga, Nicaragua.

Roof construction with mechanically anchored waterproofing sheets rightfully belongs to the most popular solution of roof structure not only in the industrial but also civil and residential construction. This is because of the speed of construction, small depending on weather conditions and often lower financial cost. But vera often there are lot of mistakes in this part of construction design.

The media regularly appear alarming reports, according to the Czech Republic gets into trouble with the fulfillment of its obligations towards the EU, due to the lack of state financial support. This information is frequently based on calculations originating from the potential recipient of government subsidies, so we cannot rule out that this is about wishful thinking. One of the sectors where we reportedly threatened is the reduction of energy demands.

During the reconstruction works of residential houses the associations of housing unit owners have to make decisions according to their financial means. It often arises a situation when windows are changed and facades of residential floors are insulated by a thermal insulation. Skirting part of the building and the roof is often in seclusion interests. Subsequent roof insulation therefore brings a number of design and implementation issues. This paper describes the necessary structural modifications of the existing double-deck roof structure (i. e. cold deck roof) to single-deck flat roof (i. e. warm deck roof) and increased financial costs caused by successive structural modifications made without consideration of the follow-up.

Currently, we increasingly need to carry out construction modifications on objects which in view of their age could be basically considered as new-build buildings at which we did not expect such a requirement. In most cases these construction modifications are caused by failures or defects of roofs, especially operation roofs – terraces. The cause of failure is often a combination of several factors. The primary source of error may be already a design project and roofing solution and quality of realization of each roof layer and roof details or unsuitable climatic conditions during the implementation. A separate issue could be the problem of the poor quality of used materials. By interaction of these negative effects then surprisingly arise failures at objects which were realized a few years ago.

Failures occurring on the facades of assembly houses often arise due to volume changes sunlit walls and incorrectly made contact details between panels. Sometimes it is not enough to eliminate them or repeated repair of damaged joints. Therefore is no choice of other solution than to overlap these joints with thermal insulation system. One such case is the subject of this paper.

New Civil Code enacts special type of solidary obligation to remedy the defects of building constructed under contract for works. All subcontractors (suppliers) of constructor, investor`s technical supervisors or construction project designer are solidary responsible together with the constructor in case the defect can be attributed to the performance they provided. However, these parties need not to be the parties to the contract for works itself (and usually are not) as their obligation arises by law.

The remedies that the investor can claim on these co-debtors, however, are limited to right to demand the repair of the defect. Investor may demand remedy on any of the co-debtors and all the co-debtors are obliged to perform the remedy in full.

The investor has to give notice to the debtor within a reasonable time. The notice can be sent to any of the co-debtors but we advise all investors to give notice always to the constructor first or together with the other co-debtors.

The thesis deals with urban sprawl and suburbanization as the effects of changes in society. It presents the basic historical overview and describes the situation in contemporary Europe. The thesis focuses on description of negative aspects, in connection with formed urban sprawl.
This work presents and describes the historical background of suburbanization in the Czech Republic. It reflects on the causes and presents the facts, leading to their understanding.
The practical part of the thesis is the application of acquired knowledge on the model, which is Brno-Útěchov. One of the peripheral parts of Brno that has grown significantly due to suburbanization in last few years.
Ideological study aims to show an alternative approach to this way of development. The main areas of interest are importance of public and private space, often neglected idea of neighborhood and the importance of privacy in terms of new houses in a face of village itself.
