The cooperation of all the creative team from the initial moments of project activity ensures proper and efficient solution to fire safety of building. Proof of fire resistance of buildings by calculation is vital need. If designer use computer software, then he is required to verify and prove their suitability for a particular case.

Quality of fire protection is achieved by appropriate education and training, research, investment in technical solutions and equipment of buildings, legislation, standards and work of professional and volunteer fire brigades. The Czech Republic in the European and global statistical comparisons, long been high on the success of fire protection of persons and property. The article is important summary of the options in the fire resistance design of structures in the national regulations.

The article deals with substandard structures structures. Assessment is complemented by practical examples and explanations of operational implications especially with regard to the durability of structures. These proposals should be applied as part of fire safety design of buildings.

The article is focused on the reconstruction of traditional timber joist ceilings with an additionally cast concrete slab. At Faculty of Civil Engineering in Brno conducted experimental work aimed at the analysis and behaviour of composite slab structures. Huge attention was put also on the separation of the concrete from the timber parts of the structure with the help of foils (separation layer) to prevent the movement of moisture from the concrete mixture to the timber elements. Therefore the increase in water content within the wood was also observed during the experimental part of the research together with the effects of the separating film to the characteristic of the coupled elements - coupling slip modulus K [N/mm].

Despite the fact that since the abolition of the "old" technical standards for determining loads and dimension of structural elements and structures already passed almost two years, still a part of our professional community doesn’t know all the impact of the introduction of Eurocodes in the field of mechanically anchored flexible roof waterproofing layers. More knowledgeable construction supervisors and also the insurance companies refuse to accept or insure mechanically anchored roof layers that are not properly constructed - including demonstrably and properly anchored.

A survey of cellular concrete facades of residential buildings in the Slovak Republic, executed between 2010 and 2011, showed extensive cracks. These can be a problem for safe anchoring of ETICS to the existing facade. Crack is a discontinuity in the mass, the pull-out tests results show that near the crack can be regarded as a weak area with a lower load capacity of anchors. This paper informs about the tests results in situ and the preliminary results of laboratory tests.

The decision to additional thermal insulation of facade begins with a question "what's million-dollar investment will bring us". Many of the available information we find say that it will bring about 50% savings in heating. The heat meter, installed at the inlet of connecting pipe to the heating system should therefore show the half consumption of heat than before, but usually the results are very different - in both directions.

This paper describes the design of the new windows of the building of the National Museum in Prague and its heat-technical assessment.

The author brings the fundamental view concerning the problem of ventilation in residential buildings with respect to the building fire protection, in his contribution. No each designer or supplier of air conditioning systems designed for use in multiple dwelling or family houses is aware of this aspect importance and adheres it in the required level. He introduces interested parties with the substantial requirements that must be solved and taken into consideration, in the article.

It is necessary to perform fire tests of wood-concrete structures of them trying to get as much knowledge that would allow the develop computational models. This paper focuses on describing the problem of composite wood-concrete structures and an overview of new knowledge about their behaviour under fire.

During the reconstruction of objects there may be situations where the noise in outer area cannot not reduced (traffic noise etc.) and it is necessary to ensure comfort at least in the internal protected area of the building. This can be achieved by using adequate building façade – especially adequate windows. Soundproof windows should be designed on the basis of traffic noise in the locality.

The first public school in the U.S. in the passive standard (K-12) was completed in November 2010. Passive house certification from the American Passivhaus Institute (PHIUS) was received in February 2011. The whole development project was quite long, so it is presented only briefly with the focus of our server. Article is provided in translation with the kind permission of the author.

Regular inspection is focused to the boiler, smoke flue and accessories condition, its security and regulation. In addition to the technical condition and maintenance, the documentation, operating instructions, manuals and other documents are under inspection. It quantifies the overall boiler efficiency of measurement results, sets reference respectively minimum boiler efficiency and suggests possible actions.

The ventilation rate in residential buildings is very discussed in present. The situation was complicated by missing or inaccurate requirements in legal regulations and technical standards. In February 2011 came into force on the national annex Z1 of European standard EN 15 665, which defines requirements for ventilation of residential buildings and also recommend suitable ventilation systems. Article briefly informs about the contents of the National Annex.

In industrial plants, in case of fire there is accumulation of smoke that endangers the user object. Under these conditions the building must be opened to the smoke can ventilate out into the atmosphere, and that firefighters could enter the building. However, this opening causes the new oxygen support combustion. It is also one of the reasons why firefighters recommend the use fire damper with automatic controls and other devices (eg, smoke curtains, screens, blinds, etc.) as soon as possible after the beginning of fire, so as to prevent any accumulation, and that remove heat and smoke. This paper deals with the equipment for smoke and heat outlet.

Assessment of existing buildings and their refurbishment is very delicate task. Every multicriterion assessment tool in the world is dealing with this problem in its own way. In terms of the Czech conditions and assessment tool SBToolCZ, cultural-historical value was taken into account in reSBToolCZ. Because this value significantly influences the possible scale of renovation interventions.
The assessment method reSBToolCZ takes into account cultural-historical value and involves it into the evaluation in a way that it is a part of the overall result. The principle is a relative setup of those criteria which are connected to the cultural-historical value. The setup depends on the scale of the possible building interventions. Currently, testing of the methodology is being made on existing buildings.
