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.
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.
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.
Thermographic measurements and their subsequent diagnosis are a relatively quick method of non contact evaluation of buildings related to heating technology. Thermal images show complex temperature fields with optional colour scales and are thus very easy to understand even for a layman. The assessment and analysis of the temperature distribution allow the identification of places with elevated heat flow.
Newly established program “Green Savings” based on income from CO2-emissions trade (Green Investment Scheme) brings several variants how to apply for subsidy for energy efficient building/renovation. Following text describes possible approaches to renovation with use of both thermal insulation of exterior constructions and change of windows/doors. Two examples of typical family houses are being described, each house in two variants of insulation (based on subsidy program criterion).
Important result is that almost all family houses that can be insulated with use of “partial insulation” subsidy, could gain higher subsidy with use of “complex insulation” criterion as well. Previous practice shows that majority of family houses can reach the higher subsidy (“complex insulation”).
