If we compare the floods of 1997 and 2002, it is necessary to emphasize the good functioning of the connection of the Prevention and Warning Service (PVS) of the Czech Hydrometeorological Institute to the crisis management system and the integrated rescue system in accordance with the set of new crisis laws in force since the beginning of 2000.

This article briefly introduces the overall concept of the OC FENIX building as a whole and at the same time clarifies the circumstances of meeting the energy performance requirements. This article will be followed by articles dedicated to the building's own operation.

The trend of the earth building material use is not only for plaster but also for the construction of buildings, as well as repairs of clay buildings, which also require the need to determine the load-bearing capacity of whole walls, not just bricks. The loadability of the walls and the influence of moisture on brick strength have been subjected to experimental investigation of SHS o.s. within the framework of the OP HRD project, the load-bearing capacity of the pillars was examined by FA and FAST staff within the BUT grants.

In residential buildings, the quality of the indoor environment can be verified by the satisfaction rates of the people who live in them. One of the forms that can provide the necessary information is a subjective assessment. This form of survey was carried out with residents of the passive apartment building for seniors in Modřice. There were 25 women and 12 men of an average age of 77 years participating in the survey. The survey proved that seniors were able and willing to accept the terms of passive houses.

The paper describes actual trends in serial deep energy retrofitting of buildings in the Netherlands. A set of photographs presents several Dutch pilot projects of energy retrofitting of post-war family houses in Heerlen, Melick and Soersterberg to net zero energy level and of one multifamily residential building in Arnhem to nearly zero energy level. The retrofitting projects were made utilizing prefabricated thermal insulation wall modules with timber structural system (that included new windows) and prefabricated roof panels. All presented projects also featured replacement of energy sources and in case of the family houses also installations of photovoltaic systems replacing roof tiles.

Innovative technologies incorporated in building constructions are able to produce renewable energy. The submitted paper deals with the current status of photovoltaic (PV) integration in building facades by selected systems. The main emphasis is focused on the newest concepts and their current development, specifically of those in combination with other progressive materials and technologies.

Results of the measurement ultrasonic pulse method are influenced by numerous factors. The influence of humidity and the method of sounding, direct and semi-direct on the measurement results was monitored. The influence of moisture and the method of transmission the bricks influences the measurement results by varying degrees. The least is influenced by the results of measurements on calcium silicate bricks and, on the contrary, on clay bricks made of plastic dough. Here shows synergistic effects of the state structures and defects in the head.

The share of population exposed to flood risk tended to grow slightly. Compared to the world, however, the proportion of people at risk of floods in the Czech Republic is very small. In the future, it is possible to achieve an even greater degree of adaptation (resilience) to floods.

In contemporary architecture, straw is used marginally, mostly in do-it-yourself construction. Although the convenient qualities of straw have long been known, it has not gained the trust of builders and designers. Construction companies have not learned to work with straw on a regular basis. In the scope of green technologies, an opportunity is emerging to use straw in professional building systems suitable for sustainable architecture. If we want to apply it in our architectural designs, we have several possibilities. The common small straw bales are suitable for many ways of structure and do-it-yourself process. This way of building process can be interrupt by logistic problems or weather disaster. Contemporary building market offers professional products made of straw: universal strongly pressed boards or system of modular units for external walls. All these ways of application are able to gain the high building quality. The innovative straw technologies enable to design and erect the energy passive house with considerable percentage of straw in constructions. Although the advantages of straw are indisputable, the next success of straw building materials depends on the interest of architects and builders.

Replacing a concept “types” of the landscape by the concept “landscapes” in the content of the graphical part of the territorial development principles (ZÚR) presents a substantial change of content in the expression of conception of the regional development, because for these landscapes the target qualities including territorial conditions for their preservation or accomplishment are established in the territorial development principles (ZÚR). The original definition of the types of landscape, which divided the territory according to the characteristic features and properties, must be gradually replaced by the definition of (real) landscapes. It is a great change, because a type of landscape expresses the characteristic properties, but real landscapes in the sense of landscape itself = specific, characteristic, have substantially different sense – they express most of all individual properties of the landscape. Therefore it is necessary to describe and give reasons for importance and the method of individual (not typological) zonation of the territory of the region into landscapes (real landscapes) corresponding to the sense of the European Landscape Convention.

The façade wall made of low-quality materials (clay and burned full brics) was vertically prestressed using monostrands. The wall strip foudation was strengthened with a transverse ties – strands.

In the paper the refurbishment of riding`s hall roof structure is presented. The combined steel-timber load-bearing structure had visible and high horizontal deformations and the gable wall was pushed out of the building.In the frame of refurbishment the diagnostic survey, structural calculations of the original and the new stage of the structure and the proposal of refurbishment works were worked out.

The article describes full-scale fire experiment of a single-storey object made of straw bales covered with clay and lime plaster. Motivation, course and results are shown, particularly focused on global fire behaviour in fire of such construction as well as its contribution to separation distances.

It is expected that the new administrative centre of Lesy České republiky would be an exemplary demonstration of the use of wood, which will be used in the form of the building material or in which the importance of wood will be emphasized in another appropriate way. The paper is focused on a proposal that won the international architectural competition in 2016.

An important BIM component to a real building model is simulation above the model. Acoustic, thermal, ambient, sunlight, for example. The simulations and the results obtained from them predict problems or situations that can occur during the life cycle and thus prevent them from occurring.

The work is focused on the investigation of the formation of gaseous thermal degradation products of retarded firwood. Samples of firwood were impregnated with solutions of 6 inorganic salts, thermally loaded and the arising gaseous products analyzed by SPME-GC-MS. There were 20 compounds identified, the highest amount was achieved for acetic acid and 2-furaldehyde as typical representatives of wood degradation. Most compounds were identified by degradation of samples treated with boric acid solution, at least with ammonium dihydrogenphosphate. The smallest amount of acetic acid and 2-furaldehyde was determined by treating of fir samples with sodium tetraborate solution, which appears to be a very suitable wood treatment agent for fire protection.

This paper shows the process of restoration, of a historic wooden ceiling, using a “dry method” – interaction between historic timber joists that are mechanically jointed with wood-based boards.The paper describes reasons for choosing the method and principles of a good design. The experience of using this method on site is also described in this article.

Appropriate measures make it possible to approach the water regime in cities in nature to mitigate negative impacts of urbanization. There are also many implementations in the Czech Republic that return water and greenery to cities.
