Thermal stability of rooms affects the local characteristic of the area, building geometry, orientation to the cardinals, the ability of heat storage, mean and intensity of ventilation, and also the size and properties of transparent parts of facade along with their shading. The most effective way to prevent the overheating of the room is to reduce heat gains through transparent structures by shading. Shading by overhanging structures is expressed by sunlit factor fs. This factor changes during the day, with the movement of the sun, and thus the determination for calculations is difficult. This paper deals with a comparison of two different methods of calculation, their comparison and the final comparison with the measured data.

The article deals with sound insulation of wooden house constructions, including the national requirements for sound insulation of walls. There is also a brief description of the laboratory measurement of the sound insulation of wall constructions and information about the sound insulation of single and double wood-based structures.

From the 1^st 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.

Existing procedures for determining heat transfer in the soil. Temperature measurements in the soil under the floor of the experimental house MSDK at the Technical University in Ostrava. The difference between the calculated temperatures and actually measured. Theoretical and real temperature field in the soil.

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 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 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.

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.

Using the test and design standards helps to obtain a lot of information and experience in determining the thermal values of window, door structures, skylights and their components. We offer knowledge of laboratory practice.

Experimental measurement of temperature changes in inverse cold flat roof structure with main focus on influence of the humidity on inner surface temperature.

Acoustic microclimate is an important part of shaping not only inside but also the outside of buildings. The article presents a case study problems associated with measuring equivalent sound pressure levels in outdoor spaces to be protected buildings. In the text of the methods to remove negative acoustic performance, or what building solutions can be used for treatment of non-compliant, measurement findings.

Cornice is a traditional architectural element that is unfortunately disappeared from the current buildings. It is often replaced by methods that do not fulfill their architectural or construction function adequately.

Acoustic microclimate is an important part of shaping the internal environment of buildings. The effect of noise on the listener is becoming an increasingly important issue that must be addressed. Great emphasis must be placed on indoor climate, not only in the home, but also in the work environment, where the interior acoustics greatly affects the quality and efficiency of operations carried out. Although the health consequences of excessive exposure effects do not show immediately, unlike expressions fluctuations in temperature that our body records almost immediately, long-term exposure to noise damages the health of the individual, not only physically but also mentally. Troubleshooting Sound microclimate has nowadays many ways, both active and passive, and becomes an increasingly important component in the search for optimal solutions and balance of all components of the internal microclimate.

In connection with the implementation of the revised European Directive 2010/31/EU on the energy performance of buildings, certain legislative provisions such as Decree No. 148/2007, Coll. Replaced by Decree No. 78/2013, Coll. are currently amending. This article is focused on the changes associated with the energy certification of buildings, the "ENB", from the perspective of changes in the evaluation ENB.

This paper examines the occurrence of extreme boundary conditions in the internal microclimate in the context of the intended use and structural design and technical equipment of the building. It refers to the occurrence of extreme conditions of the internal microclimate and the effects on constructions of buildings.

This paper describes the method for calculating the amplification of curved brick construction with composite reinforcement and compares this procedure with reinforcement made by conventional methods to gain a practical demonstration of the bent beam.

Floors are made by construction layers of different materials with unequal functions and characteristics. This formation creates functional unit. According to the material of bearing layer dry and traditional floor systems are distinguished. In dry floors the bearing layer is made by board prefabricated element, e. g. gypsum fiber board, cement bonded particle board or oriented strand board.
Floors must be designed in accordance with legislative and technical requirements. Thermal and technical requirements are of basic significance. Guarantee of required contact temperature decline value presents a significant parameter for ensuring the thermal comfort.
This article compares an influence of three materials of dry floors bearing layer and two materials of wearing layer on the value of contact temperature decline.

This article summarises the results of research on work intensity in special greenhouses based on measurement of heart rate in correlation with microclimatic environmental working conditions in these greenhouses during the summer period of the year. According to the results of measurement the indoor conditions represented by operative temperature value were higher than value required by low in Czech Republic. In order to these facts, the general conclusion of this study is proposal appropriate operation mode for workers in so specific environment conditions.

External thermal insulation composite systems (ETICS) are commonly used in the Czech Republic for thermo-retrofitting of old multifamily buildings as well as for proper insulation of new buildings constructed presently. Additional insulating layer radically improves thermal performance of a wall but at same time reduces its sound insulation in certain frequency range depending on the resonance frequency of the system. This problem becomes important in the case of noisy locations. This contribution presents a revision of the European Technical Approval Guideline No. 004 and describes suitable test methods and single value characteristic ΔR_w including relevant national requirements.
