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.

When evaluating the fire protection of building structures, the designers often get into situations when they have to choose the most appropriate option. The issue is usually not clear and brings the intuitive solution. In all these cases, decisions can be applied by using mathematics. This paper shows a variant solution in the possible ways of assessing the optimal choice of fire protection equipment in buildings. The methods and principles of the solutions are complemented by practical examples.

When heat and energy assessment of existing buildings it is often a problem to determine the heat transfer coefficient U. In many cases it is possible to use a relatively simple measuring device. The device is designed only to measure heat transfer coefficients for vertical facade structures. It could be alternatively used for horizontal structures such as ceilings and floors as well.

One of the oldest remedial measures include insulation with air cavities. The most effective solution is to create a nationwide voids under floors designed to ensure air movement. This leads to diffusion of water vapor structures and thereby reduce moisture. These measures can not be undertaken alone, they are always part of a combination of remedial interventions. An example of such a solution is given on a complicated historical building in the middle of Prague - in the palace, which is situated in steep terrain notch below the Prague Castle.

The author in his paper examines in detail the individual steps that make up the course selection process for energy services provider. Special focus is on the evaluation of the bids submitted in the tender.

Causes of failures and errors in building basement are worse distinguishable than causes of errors of building above ground. For the poor, sometimes even impossible access to the basement and the underlying structure, the method of remediation is difficult. Humidity is one of the most feared cause of failures.

Excessive moisture may be the objects of wooden folk buildings have a negative effect on all the wooden structures, which are these objects formed. This is because if any of the wooden elements has excessive humidity, there is a risk of assault at his wood-destroying biological pests (wood-decaying fungi, wood-destroying insects, rot and mold).

The major damages in concrete structures caused by fire are a breach of the concrete strength, the cracking, peeling, discoloration and deformation of elements. The most important are reduction in concrete strength becomes associated with its subsequent bursting. Although quantification of the main changes of the strength is unreal, it is possible to determine its damage by measuring the speed of ultrasound.

Within the grant project "Multi-storey buildings made ​​of wood" in the laboratories of the Academy of Sciences in Prague and TAZUS performed number of tests of wooden skeleton joints with steel plates, which confirmed the theoretical assumptions and calculations, and demonstrate their reliability and functional and economic advantages for use in practice. Here are a few of the results of experimental tests.

The aim of the research was to determine the effect of chemical degradation of the surface layers of wooden structural elements to their mechanical properties and depth to which the damage extends. Degradation of the surface layer of wood structural elements caused a chemical reaction of some compounds contained in the fire in the past repeatedly coatings applied to wood structures of historical buildings. Such chemicals include ammonium sulphate and ammonium phosphate.

Z1 Change of the standard ČSN 73 0580-1 Daylighting in buildings - Part 1: Basic Requierements was issued in January of this year. The standard itself is valid since June 2007. Z1 Change does not bring major changes, however, it specifies the text of some articles, especially the methodology of the assessment of shielding with regard to shielding by the constructions of the same building.
