“…The aim of this monitoring was to verify a quality status of ETICS, after five and ten years period of its application on selected block of the external prefabricated panel walls of the flats and document whether it is possible, that biodegradation is formed due to the increasing thickness of the thermally insulating material. This assumption is stated by some professional sources [17][18][19][20].…”

After 2000After , 2010, energy and heat savings became a key concern of the European Parliament and the Council of the European Union. The result of these efforts and activities was, in particular, the introduction of the Energy Performance of Buildings Directive (EPBD I., EPBD II., include EPBD II. recast), into the legal ambience of the EU Member States. The resulting requirements are mainly reflected in the areas of energy decrees and normative regulations and place high demands on the gradual reduction of energy consumption and overall sustainability. The new thermal-technical and energy legislation and ever-stricter criteria of the European Union require among other things that measures taken towards overall improvement of building performance should include better quality thermal insulation of building envelopes of both, new and refurbished buildings. However, one has to evaluate real impact of improved thermal insulation and energy saving parameters within the context of the overall structural and environmental design of buildings by also taking into account the ramifications of such improvements to building structures. On the one hand, there is a qualitative energy improvement; on the other hand, we encounter new manifestations of defects and failures in the form of biodegradation of facades. The aim of the paper is to present a case study based on monitoring of prefabricated apartment buildings, laboratory analysis of biodegradation microorganisms and model calculations, and to explore how increasing the thickness of thermal insulation can negatively affect the condition of the building facade and how they can start biodegradation processes in the form of mosses, lichens and algae. The paper shows the need for the interaction of all interdisciplinary contexts that lead to quality reconstruction and renovation interventions, the aim of which is to extend the life of a panel residential housing by at least another twenty years.

“…The method consists in the fact that additional volumes in the form of piles or jacks, which periodically introduced into the ground are compensate the deficit of its volume, which arises when dam is lengthening and thus protect it from excessive loosening, and faultscracks [1][2][3][4][5][6][7][8][9]. To protect the dam by this method in the extension zone of peak strain produced piling on the crest of the dam for the repayment or reimbursement deformations of the first period.…”

Abstract. This article provides estimates the parameters of protection from cracking dam due to volume compensation method. This article discusses the method of compensation dam volume. This method allows calculating the settings of security causing cracks the dam. Presents graphs of horizontal deformations of elongation calculated surface along the length of the construction and in time. Showing horizontal stress distribution diagram in the ground around the pile in plan and in section. Given all the necessary formulas for the method of compensation of the dam volume.
