Currently the thermography is commonly used for diagnosis of the building envelope quality. Major purpose is the control of construction details, thermal bridge analysis. Thermography can be used for determining the heat transfer coefficient of the building envelope. Though this method of determining heat transfer coefficient is limited and results may not always be exact. It can be caused by variability of boundary conditions and inhomogeneity of building structure. This article describes the methodology for determination of heat transfer coefficient based on thermographic measuring.

At present, it is not easy to find the optimum variant of the energy used for heating, which would be suitable for all types of houses. Economic evaluation of basic options which are offered should be enough for the choice of method of heating. The article gives an example of the selection of appropriate options for heating and hot water of selected house by comparing the technical, economic and geographical possibilities of nine basic and commonly used variants in the Czech Republic.

In a decision-making process – such as the one about national energy strategy – an economic assessment of alternative energy systems should account for social costs of electricity (and heat) production. This encompasses both private costs of the producer(s) as well as external costs, which are primarily associated with health and environmental impacts. Because the risks are not fully reflected in the prices of electricity, the application of alternative approaches is needed for monetary valuation of externalities. In this respect, ExternE is currently the most worked-out approach, which is already more than 20 years used and developed in the research projects for the European Commission. Fact that ExternE treats the analysis of externalities from bottom to up (bottom-up approach), makes possible to quantify marginal impacts of different energy facilities using different fuel types, in a particular place and time. At the same time ExternE enables to structure external costs estimates by type of the impact on health risks, loss of agricultural production and biodiversity, corrosion of materials and damage associated with climate change.

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.

Two roof structures made of timber trusses collapsed during the winter in 2005. Employees of the Department of Steel and Timber Structures at SUT in Bratislava performed a detailed diagnostic inspections of 16 sites roofed by mentioned type of timber trusses in Slovakia.

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.

This paper is based on the results of theoretical, implementation and realization work of load-bearing systems for timber frame houses. The paper contains the conclusions from designing and realization of some selected structures especially of the mountain hotel which is being built in the Krkonoše Mountains (Czech Republic).

Rating of LEED has clearly favored FSC certification (Forest Stewardship Council) over the other, let's say competing types of national and international certification of wood. Critics point to the FSC for example, that in principle there is no clearly identified reason for the creation of an evaluation standard.

The object of this work is a numerical analysis of the behavior of wood-concrete composite ceiling structure, consisting of concrete slab and wooden beams of glued laminated timber. The main objective is to explore the use of concrete slabs, which assists with wooden beams, and using models in ANSYS to investigate its behavior in the load floor construction. The accuracy of numerical analysis of wood-concrete structure fully depends on the material models. Therefore the material models will be later verified by experimental results.

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.

Sloping roofs have been being built for centuries. Until recently, these roofs had only one purpose - to protect the building from rainwater, snow or other climatic influences. Let's look more closely at the current issue of excessive moisture in the roofs and let's show with pictures some specific examples.

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.

Thermal insulation of prefabricated panel buildings is shifting to residential houses built on a brick in at the end of the 19th century and the beginning of the 20th century. These houses usually have an unheated basement with brick arches or wooden beam ceiling. Insulation of envelope and leaving the original heating system leads to a change in the internal climate and causing secondary faults.

Development of construction industry requires the development of improved properties of various materials. Innovation material properties provide cost advantages over conventional solutions, and can also bring greater flexibility in the construction. The construction applies a wide range of traditional materials, including plywood boards.
