The systems of building services in immovable heritage
Maurerová, Lenka ; Vlček, Milan (referee) ; Kabele,, Karel (referee) ; Doc.Ing. Martina Peřinková, Ph.D (referee) ; Hirš, Jiří (advisor)
The present PhD. thesis deals with the systems of building services (namely heating, ventilating and air conditioning, shading) which provide required indoor microclimate inside the immovable heritage. The work thus combines the exclusively technical field of building services (BS) and the general principles of heritage conservation. The aim of my PhD. thesis is the analysis of immovable heritage conservation processes, focusing on the current state of research and BS systems documentation. Furthermore the work concerns the possibilities of temporary measurements of indoor climate parameters inside the immovable heritage, and aims to develop a computer model (in BSim software) for the simulation of various working conditions in the selected buildings. For the stated aims were selected three representative historic houses: historical assembly hall at the Faculty of Civil Engineering, Brno University of Technology; the Palm Greenhouse at Lednice Chateau in Moravia; and Villa Tugendhat in Brno. These buildings had been surveyed for several years, and in this PhD. thesis I present their analysis, evaluation, and conclusions. The aims of this PhD. thesis broadly correspond to the transnational objectives. The present research is, for example, in accordance with the international document ICOMOS Charter (Zimbabwe, 2013) which is concerned with the analysis, conservation, and restoration of architectural heritage. The research of immovable heritage is also supported by European Union, e.g. by the Seventh Framework Programme of EU.

Reflective insulations for effective use in low energy buildings
Kalánek, Jiří ; Ingeli,, Rastislav (referee) ; Šťastník, Stanislav (referee) ; Ostrý, Milan (advisor)
The dissertation thesis is focused on thermal insulating properties of reflective insulation under boundary conditions typical for low-energy buildings. In the introductory part of this thesis the attention is focused on the heat transfer process. There is described primarily heat transfer by radiation. There is also described the reflective insulation and the methods of determination their thermal performance. The remaining part of the thesis deals with the analysis of the results obtained in experimental measurements. Measurement results are compared with the calculation model. Conclusions for technical practice including possibilities of further research are summarized in the final section.

A new device for determining the mechanical properties of wood
Kloiber, Michal ; Drdácký, Miloš
The paper presents a novel concept of a diagnostic tool for "in-situ" assessment of the mechanical characteristics of wood in a prepared 12 mm hole. The device enables direct determination of conventional strength and modul of deformation in arbitrary depth along timber profile .The aim was to verify the measurement results of the new device with measurements on already tested devices according to european standards. Experimental tests show above all a very good correlation between conventional strength by means of the new device and standard samples strength in pressure along the fibers. This semi-destructive method causes a very gentle damage and can be used for the assessmen of historic timber structures.
