Životní cyklus staveb
12.8.2013
Ing. Eva Beránková, Fakulta stavební VŠB – TU Ostrava

Every construction project passes through its life cycle, from initial idea, through the design, implementation, or to change the construction and use to disposal. Article highlights the interdependence of the life cycle of buildings with durability and amortization of buildings and does not omit important perspective on this issue, which is the economic expression of the parts of individual cost items arise during the life cycle.

From the 1st January 2013 new legal and technical regulations are coming in force, which have an impact on higher requirements on energy use for heating and this way also on energy use for heating and cooling. These requirements are stricter not only on the new, but also on major renovated buildings. Proposed measures must fulfil hygienic and energy requirements set by STN 73 0540-2: 2012. Calculated thermal protection properties of building structures are influenced by the properties of used components. Conformity of achieved real properties with the design of building depends from the accuracy of components properties, their real quality and quality of the installation. The design values for construction materials (products) are set in STN 73 0540-3: 2012.

Recently broad media in the Czech Republic coverage on hazards from PV systems to fire fighters. Similar situation was in Germany two years ago. That is why Fraunhofer-Institut für Solare Energiesysteme ISE together with TÜV Rheinland and other partners implemented a research project „Assessment of fire risks in PV systems and development of safety concepts for risk mitigation“. The project concluded that the fire risk of PV system is much less than it is publicly alleged in Germany.
There is a small risk that fires can be started by PV components. This risk can be reduced by careful installation, initial verification i.e. inspection and testing, periodic verifications, (yield) monitoring to detect degradation problems, and verification of test procedures and maintenance requirements for conventional AC- components. Overall conclusion is that PV systems are not maintenance free.

Blocks for masonry with integrated insulation material are known over 30 years. Especialy hollow clay bricks have low U value due to optimalization of their geometry with low thermal conductivity of ceramic body. Finaly integrated insulation material into the holes in bricks results to increasing of thermal insulation properties. Article is focus on behavior of hollow clay bricks with and without integrated insulation material in dynamic heat load.

The paper is focused on the results of testing of a key segment of the tunnel lining, which is important for the capacity of the tunnel lining itself. Strength parameters of the designed structural steel fibre reinforced concrete (SFRC) element are described. SFRC key segment with fibres dosages 50 kg/m3 are compared with ordinary RC key segment.

Národný plán zameraný na zvyšovanie počtu budov s takmer nulovou potrebou energie

The development of "national plan for increasing the number of nearly zero energy buildings" is a major task of the European Parliament and of the Council Directive 2010/31/EU of 19 May 2010 On the energy performance of buildings, which was transposed by Act no. 300/2012 Coll that amends and supplements Act no. 555/2005 Coll. On the energy performance of buildings, and amends and supplements Act no. 50/1976 Coll. Planning and building regulations (Building Act).

The article introduces the testing procedure of levelling instruments in construction. Generally described testing and validation procedure of levelling instruments (optical and digital as well) is supplemented by results and evaluation of four selected levelling instruments (Sokkia C40, Geo Fennell NO.10, Spectra AL100 a Leica Sprinter 150) used to work in technical levelling.

The heat transfer coefficient is an important parameter in the energy rating of buildings. It is certainly interesting to the influence of this parameter on the energy rating. In this article, this is calculated on a real house. This is designed as passive.

In order to assess the diffusion rate of solar and wind power plants in the Czech residential sector, we analyse data on licenses for business in the energy industries. We arbitrary set the maximum installed capacity for installations on residential roofs on 10 kWe and find out that the current number of such installations corresponds to 0.5 % of inhabited family houses in the Czech Republic, with most installations being in the Pilsen region and least in the Karlovy Vary and Liberec regions.
When compared with the overall development of solar power plants, it shows that the installations of up to 10 kWe accounted for about 35 % of all the solar power plant installations, but only for 1.9 % of the total installed capacity. Micro wind turbines are up to now not very expanded; we found only 20 installations of micro wind turbines.

The paper presented method of laboratory measurements for specifies air permeability of building board elements of wood- based. The aim of laboratory measurements was to designate value of air permeability of building board elements of wood- based. The results from measurement are in form protocols which indicate air permeability for differential pressure 50 Pa. The value air permeability decides about application and quality building board elements for airtight layer.

For reasons of failure to material detarioration have occurred to many premature or sudden failure of building structures. The quality of the design, execution and maintenance of building structures is a serious problem in the present. The paper presents probabilistic models of concrete deterioration that cause depassivation of reinforcement.

The paper focuses on the description of construction technology of concrete shell blocks with the system of internal thermal insulation. The emphasis is placed on the building envelope. There is described construction technology of external walls and implementation of internal insulation. Another part deals with description of the main details that must be resolved differently than a normal brick house. In conclusion are compare advantages and disadvantages of internal insulation.
