EU declared the year 2013 us year o air. Producers and manufacturers of plastics, including EPS insulation for buildings contribute to improve the quality of the air. It describes approaches to solving envorinmental and health aspects of EPS applications.

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.

Change of the standard ČSN 73 0810/Z1 (valid from  1^st June 2012) introduces a new term - so-called „equivalent DP1“.This represented an exception in the classification of non-combustible components for some products. This exception was cancelled by the Change ČSN 73 0810/Z3 valid from 1^st July 2013.

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

In relation with the implementation of the revised EU Directive 2010/31/EU on the energy performance of buildings are currently changing some of Czech legal regulations and new methodology for energy performance assessment is introduced . This article focuses on an example rating the standard family house with conventional solution of building envelope and technical systems, using the new evaluation method. For this object will be also an obligation to issue an energy performance certificate as required by the Consolidated Act No. 406/2000 Coll., as amended.

In the second half of the last century the village changes in terms of demographics. First, the outhouses lose their importance, later, the living houses got empty. At best, the homesteads are used for weekend recreation. As a result of these changes, and due to improper construction impacts the houses dilapidate. There is material destruction and creation of static structural failure of the house.

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.

Other important aspects of wind conditions over the area of the Czech Republic are discussed in the second part of the article. This include the distribution of wind speed and prevailing wind direction, which, can vary significantly between the sites in the Czech Republic.

While an actual map of the mean wind speed at the height of 100 m above ground (i.e. at the height of state-of-the-art "large" wind turbines) was created and published in 2007 – 2008, only less accurate older data were available for the conditions closer to the ground. This gap is filled by presented article and concurrently published map of the wind speed at the height of 10 m. Furthermore, other important aspects of wind conditions over the area of the Czech Republic are discussed. These results can form a useful tool for those interested in construction of small wind turbines.
To calculate the average wind speed at a height of 10 m above the surface the same procedure and the same input data as for “wind map” at a height of 100 m above the ground were used. The resulting wind map is a synthesis of three calculation models used for long time at the Institute of Atmospheric Physics AS CR: VAS, WAsP and PIAP.

Prefabricated single-storied concrete assembly hall is roofed with prestressed lattice girders, skylights, purlins and roof slabs. Significant problems of a roof structure were found out. The method and results of examination and the principles of reconstruction are described.

It has been one year and a half since Technical Standards Information TNI 74 6077 – The windows and external doors – Requirements for incorporation has been published. What is the consistency or inconsistency between the demands on windows and doors manufacturing, their installation and actually reached geometrical tolerances of building construction? What this state brings to manufacturers of windows and doors, what to building contractor and what to customers? The view through the eyes of quality control.

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.

To calculate the fastening plan of mechanically fastened waterproofing roof sheet (MEFAWAME) it is necessary in addition to the correct wind suction procedure also determine by the corresponding way the resistance (allowable stress) of the fasten system.

The paper presents examples of defects that are associated with application of finishes impervious for diffusion to damp concrete, or concrete, which water in liquid or gaseous phase can migrate through. Described are the possible mechanisms of failure.

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.

The article describes unbiased comparison between two different methods of building protection against subsurface water and moisture – the foundation structure of waterproof concrete and waterproofing envelope based on the bitumen or plastic continuous sheet water proofing. The confrontation of properties and risk factors of the methods is made from the perspective of waterproof concrete structure which is the main content of the article. The comparative analysis is supplemented with the photos from field surveys and the results of independent laboratory tests.

Cross laminated timber is likely to happen in the near future, the most important product in solid wood construction in residential and high-rise construction. Depending on the size of the used components and their mutual orientation can produce a wide range of products.
