In buildings registered in preservation zones the preservationists require keeping of the division and shaping of the opening pane girts and respecting of the original look of the facade. Keeping the girt profile, it is nowdays permitted to glaze the window wings using insulation glass. The manufacturers of windows still make many mistakes affecting not only physical characteristics of the opening panes but also their durability – life time.

The surface temperature as one of the most watched parametres of the opening panes and light enveopes not only in the Czech Republic is being assessed in a view of risk of water vapour condensation, or more precisely in a view of their health and a hygyenic flaws and ecologically sound environment where inbuilt. The mening is determination if the structure is suitable for the marginal conditions or whether is necessary to choose another structure.

Grey form of an expanded polystyrene (EPS) insulation have been used in the Czech Republic since 2005. It is necessary to respect application differences in between grey and white form of EPS. It´s not EPS such as EPS, in this case.

The surface temperature as one of the most watched parametres of the opening panes and light enveopes not only in the Czech Republic is being assessed in a view of risk of water vapour condensation, or more precisely in a view of their health and a hygyenic flaws and ecologically sound environment where inbuilt. The mening is determination if the structure is suitable for the marginal conditions or whether is necessary to choose another structure.

In the article, I would like to draw attention to the issue with an outside window lintel on existing double glazed windows. The lintel is mounted below the other lintel and can therefore when replacing windows in modern window to form a problem. The article presents possible solutions window lintel. The most appropriate way is a solution that includes the total renovation of the building envelope with the replacement of windows.

The article presents a technological procedure and possibilities for surface treatment of different materials by using compact parts of CO₂dry ice. A purifying medium is accelerated in the nozzle of the SDI Select 60 device by compressed air stream to a supersonic speed, and so it reaches high kinetic energy. The impact of CO₂ at the temperature −78.8 °C rapidly cools down the surface; dirtiness becomes brittle and loses its base adhesion, causing temperature shock. Simultaneously with this temperature effect, dry ice intensively sublimates, increases its volume and removes, at high inner tension, the impaired surface of dirtiness without any formation of abrasion waste. The device is applicable to the removal of contamination from elements which cannot be saturated with water or when it is necessary to modify elements with no need to dismantle them. The report introduces the technology when removing contamination on the surface of wooden construction elements, artefacts and stone statues, as well as when forming a relief on the native wooden surface and at a surface treatment before the application of paint, or fungicidal and insecticidal agents.

Drying masonry building structures using high-frequency electromagnetic (EMW) radiation, so-called. Microwave technology in construction practice becoming more exercise. It is an innovative method which can be used to remove excess moisture significantly speed. This article focuses on the description of physical phenomena that occur during drying and comparison standard, the most commonly used, processes for drying buildings.

The heat transfer between apartments operated on various internal temperatures objectively exists and under certain circumstances this may represent an important proportion of the total heat loss of the apartment. Is it possible to quantify the financial impact of the heat parasitism?

In the last article on the regeneration of residential buildings, I said that additional contributions will be more focused on topics that are crucial for the effective functioning of the heating system, or which are controversial perception among the general public. The first topic that fully meets the two criteria is the heat transfer between the different flats in apartment houses.

The article deals with the issue of economic accessibility of energy-saving buildings; respecting the possibility of financial support from the National programme “Nová zelená úsporám” (New green savings programme, abbr. NZÚ). The purpose of the article is to disprove some of the incorrect interpretations and myths connected with this topic. It point out the good practice examples of a high-quality projects preparation, their successful submission into “New green savings programme” and following realization. Article aims either at lay or professional reader.

This paper deals with additional moisture protection of the building structures on the contact with the ground. The presented remedial work is based on the WTA guidelines, which recommend the optimal material and technology. Low and high pressure injections are mentioned, as well as additional horizontal waterproofing. It is underlined that important role plays the suitable materials and compliance with the prescribed technology. We cannot forget on effect of splash water and effect of condensing moisture. The success of remediation is conditioned on the highly professional realization of details. Specific solutions are illustrated in the appended figures.

Basic principles of designing and realization of radon remedial measure in existing buildings are presented. Typical effectiveness of particular measures is summarized and schematic drawings of measures used most frequently are provided.

If you ask hygienist, how to define the term " indoor environment quality", the aswer will be: A set of physical, chemical and biological environmental factors. All of these factors should have - if possible, and the current state of knowledge it allows - hygienic limits as insurmountable values, protecting human health.

The exact determination of emissivity and the following determination of surface temperature of glossy materials can be carried out e. g. after applying a material with a known value of emissivity on the surface (e. g. self-adhesive foil or spray tint). The contribution deals with other possibility of determination of surface temperature and the influence of emissivity of glossy materials using a metal shield that reduces the negative influence of the reflected radiation during the termographical measurement.

The article deals with the determination of thermal conductivity mineral insulation. Mineral Insulation Manufacturers Association conducted a survey on this topic between building designers and describes the various possibilities of calculation and determination of these values and the differences between them.

Text is focused on the energy effectiveness of the heat pump installations operated in the system for space heating and domestic hot water preparation. Conventional heat pumps are operated in hot water system with low coefficient of performance (COP). Heat demand structure in multifamily buildings with high heat use for hot water influences the energy effectiveness of heat pump operation. Moreover, combination with space heating results in high installed heat capacity of the units which is not used during the year.

A sophisticated system of ventilation and cooling (air conditioning) in representative rooms of the valuable historical building of the Olomouc town hall is described in the paper (see pic. 1).

After a complex and detailed technical and historical survey it was decided to use the original chimneys and their flues, at present out of operation (see pic. 5) for bringing the air into the rooms. The flues were milled and steel liners were inserted, in order to bring the air into the conditioned rooms. Thanks to this solution – responsive and witty in the same time – the vaults and murals in the ceremonial hall and adjacent service rooms remained intact.

Within the rooms the air is distributed through very flat pipes laid into the cinder embankment under the wooden parquetry that had to be repaired, too. In the same time new cables for sound and security systems, until now missing, were installed under the floor. The air is brought into the rooms through the slot diffusers, integrated into the carpets. The cooling units were installed under the renovated window sills.

Similar system was implemented in the mayor´s office, his or her secretariat and a great reunion hall.

Owners of residential houses during the reconstruction usually think the following: What does not have obvious defects, it's okay. By this simplified manner can not be seen on the heating system in any way. A sign that the heating is okay, it is not only the fact that heats, but mainly that operates efficiently. And it does not recognize at first glance.

There are two possibilities how to place the ETICS on the market of the Czech Republic in this time – the national and european certification. Against the european certification valid all over the European Union the national one entitles manufacturer to sell the product just in Czech Republic territory. This contribution further mentions the basic specifics for each type of these certification processes.
