This diploma thesis is focused on material and technical alternatives of the building envelope and heating of low energy houses and passive houses. The theoretical part is focused on main principles of designing low-energy building standards. The practical part is aimed to the best economic and technical solution of new buildings in low energy and passive standard on a particular case. At the end of thesis the evaluation of the best design options is performed.

This thesis studies comparison and connection of two spectrometric methods – low energy ion scattering spektrometry (LEIS) and secondary ion mass spectrometry (SIMS). SIMS method, despite its many positive qualities, suffers of so called matrix effect, which makes quantifiaction of data very difficult. LEIS method on the other hand is immune to this effect and so it’s suitable completion of SIMS method. As a convenient sample have been chosen AlGaN samples with various concentration of gallium and aluminium. In the first part of thesis is introduced physical essence of SIMS and LEIS method, experimental details and studied samples. In second part of the thesis there’s a description of measurements and comparison of data gained by each method.

Diploma thesis "Low-energy building" presents low-energy construction trends and their price comparision with conventional contruction. This thesis defines basic low-energy building terms, both building and construction work evaluation concepts and specifics of low-energy construction. Practical outcome is comparision between passive and conventional buildings, including economic appraisal.

This construction programme deals with a hermit colony located in the western part of the Vysočina Region. This hermit colony has been established to provide accommodation for women living in this area permanently while offering an opportunity of occasional relaxation for people who are living hectic lives in urban environment. The aim of my project is to design the remaining parts of the colony, i.e. two hermitages and the community’s chapel. A hermitage is a one-storey building intended for one person only. The load-bearing walls of the individual hermitages are designed to be built from different materials (wooden and masonry constructions) whereas the elevational structures of all the buildings are to be the same. The chapel’s wall system combines stone and wood. The chapel will serve solely the purposes of the community. The main objective of my project is to respect and maintain the natural features of the landscape to the maximum extent possible.

The goal of the project is development of a project documentation for a building: Low energy block of apartments. The documentation was processed in the depressed for construction realization. It solves a four floor block of apartments with flat warm roof and partially depressed parking garage. The structure is designed with risen requirements on thermal properties. The project also solves a concept of heating system. Its energy efficiency was analysed using precise calculation acc. ČSN 73 0540 and processed statement of energy efficiency. The result energy consumption of the structure is B – very efficient.

The thesis deals with energy simulation of a heat recovery system in coupling with a ground heat exchanger (GHE) in a low-energy family house with warm-air heating and ventilation. The effect of GHE on operation and effectiveness of a heat recovery unit was assessed from the results of the simulation. Next, energy and economic benefits of the heat recovery with and without GHE and consequent savings were evaluated as well. The profitability of the investment was assessed using comparison with the investment costs. Recommendations for the operation of the system were suggested.

This master's thesis deals with study of the injected charge contrast mechanism of doped semiconductors by using the ultra – high vacuum scanning low electron energy microscope (UHV SLEEM). The aims of this work were to explain the injected charge contrast mechanism, to ability of this contrast mechanism to map the dopant density quantitatively and to identify the influencing factors.

The thesis deals with an energy simulation of a ground heat exchanger (GHE) in classical and brine performance, which is used as an accessory of warm air heating system recovery in a low-energy family house. On basis of simulation results, the benefits of both heat exchangers were assessed. Furthermore, the energy and economics savings of heat recovery coupled with GHE were evaluated. Comparing the investment costs, the profitability of each investment were assessed and recommendations for the operation, implementation and appropriateness were outlined.

My diploma thesis is focused on design scheme of low-energy family house’s heating system. The goal of the first part of thesis is an introduction of the object following by calculations of transmission coefficients of heat through constructions and calculations of heat loss. Creation of proposal and calculation of underfloor heating output as well as panel and piped radiators and convectors are followed by proposal and calculation of dimensions of piping, pressure loss of underfloor loops, panel and piped radiators and convectors. The thesis also contains design of heating pump with bivalent heat electrical source, calculations of need of heat and calculations of total costs of working heating system as well as design of storage tank and accumulator for hot water. The last part of thesis is focused on control of the heat system.

Diploma thesis deals with issue of another possible application of PUR foam in the building, especially during the construction of the masonry structures with the integrated thermal isolator in the low-energy and the passive buildings. The practical part shows the production of the test sample of selected PUR foams and the trials that were performed on the samples. The aim of the thesis was choosing of the PUR foam with the best attributes which would be suitable as an integrated thermal isolator into masonry structures. In the conclusion there was chosen the best foam from which the masonry fragments were made. The static tests were performed on these fragments.
