Ensure environmentally friendly disposal and possible recycling of old and damaged clothing is quite problematic in practice. The problem with waste disposal of textiles is the fact that clothing is a waste mixture of natural and synthetic fibers. The paper deals with possibilities of development and production of insulation materials based on waste textile fibers and their subsequent application in modern floor construction.

This paper describes the results of research aimed at studying the real hygrothermal behaviour of different types of cellular concrete products for masonry structure, particularly in terms of thermal characteristics depending on temperature and moisture content of the material.

Calculations of heat transfer through soil according to ISO 13370 [1] and EN ISO 10211 [2] are rare. They stands out not only for the specific subject of interest, but also for a completely different philosophy of the calculation for determining the physical quantities. It is clear that this is unfortunately in conflict with the definitions and in conflict with real physical phenomenons. We try to approach the reasons for this assertion.

The author in his paper examines in detail the individual steps that make up the course selection process for energy services provider. Special focus is on the evaluation of the bids submitted in the tender.

For some time I start to have an allergy to the word ecology and ecological architecture. These words can mean many things, depending on what you need. So I'll try to put my opinion into a more specific framework. What is green architecture? Why is modern architecture abnormal when waste is normal? What is the situation in the Czech Republic for the use of "POTENTIAL SAVINGS?" How is the Czech Republic architecture environmentally friendly?

Causes of failures and errors in building basement are worse distinguishable than causes of errors of building above ground. For the poor, sometimes even impossible access to the basement and the underlying structure, the method of remediation is difficult. Humidity is one of the most feared cause of failures.

The author is concerned with the design of flexible placing and the explanation of resonance effects in a flexible element of one-mass and two-mass placing machines on the basis of theoretical analyses and practical experiences. He highlights problems regarding rotational machines placed flexibly due to high excitation frequencies to be used for significantly lower excitation frequencies. He points out of the necessity of cooperation between the designer of the machine flexible placing and the building safety engineer in cases of light construction structures of floors and ceilings.

The paper focuses on the differences between equivalent thermal conductivities of the masonry from hollow bricks in vertical and in both horizontal directions. Recent CFD studies presented the ratio between thermal conductivities in vertical and in horizontal direction (perpendicular to the surface of the masonry). This study shows the relation between thermal conductivities of the masonry in both horizontal directions.

Excessive moisture may be the objects of wooden folk buildings have a negative effect on all the wooden structures, which are these objects formed. This is because if any of the wooden elements has excessive humidity, there is a risk of assault at his wood-destroying biological pests (wood-decaying fungi, wood-destroying insects, rot and mold).

The major damages in concrete structures caused by fire are a breach of the concrete strength, the cracking, peeling, discoloration and deformation of elements. The most important are reduction in concrete strength becomes associated with its subsequent bursting. Although quantification of the main changes of the strength is unreal, it is possible to determine its damage by measuring the speed of ultrasound.

Sloping roofs meet today not only the function of protection from the rain. Use attic space for residential purposes made ​​them cladding, which must withstand moisture influences from both the exterior and the interior. Frequently discussed issue is the composition of construction and materials used. These two factors strongly affect the hygrothermal regime in construction and thus the quality of the internal microclimate.

Within the grant project "Multi-storey buildings made ​​of wood" in the laboratories of the Academy of Sciences in Prague and TAZUS performed number of tests of wooden skeleton joints with steel plates, which confirmed the theoretical assumptions and calculations, and demonstrate their reliability and functional and economic advantages for use in practice. Here are a few of the results of experimental tests.

Family houses belong among the simple structures that are usually built with a classical way. Although the technology of construction is not difficult, it is possible for gross neglect of basic technological practices and the protection of buildings during construction to cause such damage, which is difficult to repair, even for the increased financial costs. Evidence of this is an example of one family house for individual living in the suburb of Prague on the basis of expert opinion.

The aim of the research was to determine the effect of chemical degradation of the surface layers of wooden structural elements to their mechanical properties and depth to which the damage extends. Degradation of the surface layer of wood structural elements caused a chemical reaction of some compounds contained in the fire in the past repeatedly coatings applied to wood structures of historical buildings. Such chemicals include ammonium sulphate and ammonium phosphate.
