In the first half of this year new came in force new standards that define new requirements for the design of thermo insulation systems in buildings. They are ČSN 73 0810 - Fire safety of buildings - Common provisions (April 2009) and ČSN 73 0802 - Fire safety of buildings- Non industrial buildings. The changes in these standards bring a number of major innovations. Let's have a look with them with the aid of images.From the result it is evident that the implementation of external thermal insulation systems for buildings with final approval before 200, and new buildings must follow the additional requirements listed in the articles of the standards ČSN 73 0810 and ČSN 73 0802, particularly in relation to the classification of types of components on the DP1, DP2, DP3. The implementation of additional insulation requires good design, preferably done by a specialist, the application of comprehensive quality and the choice of contractors with certifiable good references.

The article reacts on changes that were made in program "Zelená úsporám" in recent days. Previous article described how to reach required standards for successful subsidy application in two ways. Following text focuses on changes in this approach both from subsidy amount and possibility of subsidy itself viewpoints. In general, portfolio of potential subsidy applicants has been extended, but necessary quality of subsidized measures has been kept.

Solar collector is designed to obtain part of heating requirements of the buildings from the sun. Air-type collector that use air as the heat transfer medium is one of the simplest methods of solar heating. This solar heating technique can be made part of house design and construction.

The examination method Blower-Door test (fan pressurisation method) is used for measurements of air permeability of buildings and is also used for leakage detection. The result of the measurement is air leakage rate at the pressure differential across the building envelope of 50 Pa. The article points out leaky details which often appear at constructions. The article shows the possibility of using infrared camera and anemometer for leakage detection.

New Czech technical standard ČSN 73 0810 Fire protection of buildings - General requirements was issued in April 2009. This standard replaced the standard of the same title issued in June 2005. New standard has expanded or changed some of the paragraphs. Important changes are defined in the article.

The development of the implementation of open track diffusion is influenced by the availability of certain construction materials and it is also subject to the management of technological processes and the overcoming of ingrained stereotypes.

Growing interest insulation very often results in choosing companies with low price for materials and installation, without considering whether technological standards are observed. The analysis of defects occurring in contact insulation systems should warn investors on how to proceed when choosing a supplier, so as to avoid claims for the resulting defects, or in a extreme case, so the insulation will not have to be replaced. It also wants to draw the attention of suppliers and designers towards those major faults when installing the contact insulation, and bring awareness to the general public about deficiencies that could arise, in particular with the implementation of contracts with no technical supervision.

Different prediction methods for the Sound Reduction Index of single building structures in laboratory conditions and for the Apparent Sound Reduction Index in buildings are presented in following paper. A short discussion of methods is done regarding to input data, assumptions of calculations etc. The main part of this paper is focused on a comparison between predicted and measured results, which leads to evaluation of methods´ accuracy. This paper is based on author´s PhD thesis.
