Explosion effects belong to the category of accidental actions. During the use of building or during its construction may occur only exceptionally. ČSN EN 1991‑1‑7 (73 0035) requires to consider this type of actions and the solution of structural design to withstand the accidental action.

The article informs about why and how to solve pressurization of protected emergency exits (hereinafter also referred to as the abbreviation of CHÚC). Design of protected escape route with permissible concentration of carbon monoxide only is not today's reality. Other toxic combustion products such as hydrogen cyanide, formaldehyde, hydrogen halides, oxides of nitrogen and other even at low concentrations make it difficult to escape from the danger area. For this reason, the standard EN 12101-6 for ventilation of protected escape routes does not deal with the dilution of smoke, but establishes criteria for maintaining of protected escape routes free from smoke.

Evaluated the effectiveness of austerity measures must take into account both external and internal temperature of the object and the value of the average heat gain at which heat consumption was measured. Article analyzes the individual components, and presents the average values.

Video Image Fire Detection is a modern fire detection mechanism of phenomena and processes accompanying fire. Main advantage is the ability and speed of smoke detection, independent of the arrival of the smoke to the sensor. Video Image Fire Detection can achieve higher sensitivity than conventional fire sensors by simultaneously monitoring different parameters in a large area. The article gives basic requirements for Video Image Fire Detector for Automatic Fire Alarm Signaling.

Relatively same heat savings can be achieved with thermal comfort by regulation, or without thermal comfort by switching off the radiators. It depends on how the heating is operated and how heat gains are used in the building. The article contains a simplified example that relations between real and purported savings of heat explains.

Components and systems for general and fire building ventilation, their safe and reliable function significantly affect the fire safety of the building. The aim of this paper is to inform about the current state of legal and technical regulations that must be followed when placing the products on the market and its building in in the Czech Republic.

The behaviour of real structures in some cases differs from the structure modeled in computational program. Article deals with the influences that can affect the characteristics of the structure, so that they affect the surface temperature of the structure. In particular, the moisture inside the material and air humidity.

Can additionally insulated prefab-panel buildings meet the low-energy standard, or even overcome? The article contains a detailed analysis of the specific parameters of the building and heating system before and after additional thermal insulation of building, supplemented by the results of measuring the actual heat consumption in the period 2010-2011, with output data transferred to the appropriate temperature normal year.

The fire behavior of wood is very predictable phenomenon. Using the simplified computational methods it can be determined the bearing and separating function of structures. The bar-shaped load-bearing elements is a parameter R (resistance and stability) for PCB - vertical and horizontal structures for the threshold criteria R, E, I, (capacity, integrity, insulation). In many cases it is very difficult and according to Eurocode 5 (1-2) almost impossible to determine the start time charring timber under fire protection and fire protection violation time.

Hydraulic control of heating systems means - except hydraulic control of central heating - hot water system control. Despite the fact that hot water system control is the duty of the law, unlike hydraulic control of heating systems that have been implemented since 1998, hot water systems are controlled sporadically.

Modern construction system for low energy building, passive and zero standard or energy-autonomous buildings and increased popularity of solid wood construction means interventions into the very structure, its statics, building physics, as well as fire protection properties. Some prototype design solutions are not proven, whether tested, by trustworthy computing analysis nor verification of long-term use of the building.

The use of straw bales as insulation and in some low-rise buildings as elements for substructure are currently namely on the edge of building technologies but it is also technology that have potential in certain contexts to a wider application. It is shown by the implementation of experimental structures and research results.

The paper gives an overview of the National Technical Library building in Prague. The paper describes the architectural design, ventilation and air conditioning system of the building. It is also mentioned computer simulation and monitoring of the building.

Elevators belong to a very important building services and technologies. For these reasons, they need to pay attention not only in terms of proper technical implementation, but also in terms of fire safety. In particular, fire and evacuation lifts, which are also very important fire safety devices (hereinafter referred to as "PBZ") must also meet the stringent technical requirements of fire protection. In the first part we deal with the terminology and technical requirements.

In addressing the fire safety of buildings it is necessary to know the value of fire resistance of building products and constructions of building and to design constructions, which meet required fire resistance values. It is necessary to distinguish two categories of elements: building products and construction.

Commonly practiced simple statistical analysis of heat consumption shows differences of measured values, but not thermal energy savings, for which the buildings are insulated and the heating systems re-regulated. Differences of measured values at different temperatures inside buildings have no practical benefit for the consumer because they say nothing about the actual and they do not allow to adjust the heating mode nor by changing the behaviour of people in apartments, nor by any other instrument. Heat consumers lack information on the relations between the average internal temperature of objects during measurement of heat consumption, on the influence of heat gain and possible heat savings in compliance with the legislation provided average internal temperature of the object.

Determination of the development of fire in the compartment with subsequent detection of temperature in different parts of the structure requires knowledge of many parameters. The most important step is to determine the design fire scenario that matches the extraordinary fire situation best. The design of fire can describe the temperatures in the fire department and determine the heat transfer in structure. Let's look at several models and the thermal and mechanical load of structures.
