The article deals with a comparison of a room area size which is suitable for reading and writing according to two daylight evaluation criteria. The first one is the daylight factor which is determined under the CIE overcast sky model and it is traditionally used for quantitative daylight evaluations of buildings. The second compared evaluation criterion is the daylight autonomy which is one of new daylight metrics whose calculation is based on daylight illuminance values throughout the year and for a specific location.

In the last two decades, the US hardwood industry has experienced an important increase in their exports to key markets in Southeast Asia, and Western Europe. However, the export to Easter Europe is currently limited. In these emerging economies, production of furniture and many different kinds of wood products are on the rise. Favorable labor costs, progressive design, and available material resources are key factors that sustain the growth of these industries. The forest products industry is also significant consumer of hardwood lumber. Despite the fact that Easter European countries have its own hardwood material resources, the rapid industry growth, increased sustainability practices, and increased demand of high quality material may require the need for additional material sourcing.

The paper focuses on current European trends in the application of some new and innovative types of fire safety devices, preventing the initiation of fire or explosion and detection systems. The article also deals with the issue of placing these construction products on the market.

Industrial chimneys are civil engineering works, which in addition to static and dynamic effects, direct and indirect loads, are also exposed to significant non-stationary environmental loads. Analysis of their durability focuses on the evaluation of vertical cracks, corrosion of concrete and reinforcement, which have a decisive influence on the resistance of the chimney's shaft with regard to the ultimate and serviceability limit states, as well as their durability.

Open-space they do not work, and they will be replaced by coffee shops in the future, says British Telecommunications futurist Nicole Millard quoted by The Daily Telegraph.

The article describes the methods of the surveying data and documentation production. The documentation is used for the process of planning, realisation and reconstruction of transport, energetic, industrial, ecologic and public objects. The documentation is also used in the remediation process and the protection of the buildings and historical objects. In these processes, it is necessary to know the spatial dimension – location data, the location of these objects on the Earth's surface and shape and dimensions of these objects. The activities that lead to the realisation, reconstruction and remediation of building objects require a quality maps, photogrammetric images and geodetic models (3D models), which are mostly realised in a suitable interactive graphic PC system in 3D digital form.

Heritage care specialists in the repair and reconstruction of historical buildings prefer using of previous working methods and especially materials, sometimes too strongly. It is not always easy to satisfy their requirements, with regard to the problematic of static object state. It is necessary to find suitable compromises.

The composite materials for strengthening/reinforcement a concrete has become the new construction product set up for compulsory verification pursuant to Act No. 22/1997 Coll. (č. 22/1997 Sb.) as amended by Government Ordinance No. 163/2002 Coll. (č. 163/2002 Sb.) as amended by Government Decree No. 312/2005 Coll. and No. 215/2016 Coll (č. 312/2005 Sb. a č. 215/2016 Sb.) This reinforcement exists in several different types, and accordingly, it also has significantly different properties which must be strictly respected in its use.

Despite efforts to maintain quality during the construction of reinforced concrete structures, it is relatively common for improper reinforcement to be used contradicting the project, which can lead to serious structural defects. It is then up to non-destructive testing methods to prove these defects. The key is to choose the appropriate method and device for the task.
