The paper presents an approach in the determination of the most economically efficient building from the viewpoint of the costs of envelope's composition, the present value of heating costs and the costs incurred in fitting out the boiler room (hereinafter: the costs of the boiler room). The process of determination starts with the selection of a certain building in the phase of project engineering, next different combinations of envelope composition are numerically analysed and finally the optimal solution or approximation of that solution is defined on the basis of the analysed results. The approach is presented on the simulation case of a single-storey house. The result of the study is presented by a set of parameters showing different costs of building envelope from the point of initial investment for a selected energy demand of building. In the second step we calculated the present value costs of heating and compared them with the additional cost of initial investment in the envelope and additional investment in the building's boiler room in order to determine which combination of envelope and heating system is the most economically efficient.

The importance of building large-size glazing into timber structures has significantly grown over the last decade due to the enhanced physical characteristics of glass panels and owing to the fact that proper integration of both materials, timber and glass, has a positive impact on the energy efficiency of buildings, which was one of the major reasons for carrying out our investigation. This paper presents the results of the experimental research on timber-glass wall elements where glass panes are directly bonded to the timber frame, leading to a load-bearing and visually interesting wall element which is suitable for lightweight timber structures.

Virtual learning environments are irreversibly shaping the way of teaching and learning at universities. They have become more and more popular as practitioners recognized the advantages virtual learning environments offer when applied in online teaching and learning. Nevertheless, most of the virtual learning environments do not provide straightforward support for inter-university interoperability between heterogeneous learning environments. This paper presents a use case of ITC-Euromaster with collaboration concept for inter-university interoperability. Furthermore, a taxonomy, an ontology and a high level architecture using intelligent software agents that enable dynamic inter-university interoperability are proposed to further develop an existing virtual learning environment used among four European universities.

Alternative types of roundabouts are usually more recent and have been implemented only in certain countries. Typically, they differ from "standard" roundabouts in one or more design elements, whilst the purposes of their implementations are also specific. The main reasons for their implementations are particular the disadvantages of "standard" one- or two-lane roundabouts in particular circumstances or changes of "actual circumstances" which in the past has led to roundabout implementations. Today, several different types of roundabouts are well-known ("mini", "double mini", "dumb - bell", "with transition central island", "with joint splitter islands", "traffic signal controlled", "assembled roundabouts" ...), and it is possible to stipulate that they will be further developed in the future. This paper illustrates two relative new alternative types of roundabouts - "turbo" and "flower" roundabouts and their comparison from design, traffic safety and capacity point of view.

Importance of building large-size glazing into timber structures has significantly grown over the last decade. This was one of the major reasons for carrying out the presented experimental research on timber structures with a fixed glazing placed in the external sides or in the middle of the timber-frame wall elements. Timber frame, to which glass pane is directly attached, forms the composite wall element, which contributes to stability of the entire system with its load capacity. Different types of adhesives with specific characteristics were used and they consequently caused different impacts on a wall composite. Both concepts, with bilateral glass as well as single glass lining in the middle of profile, are presented.
