Diploma thesis entitled Influence of green roof insulation on the costs associated with one operation with an assessment of the design of alternative solutions for external contact thermal insulation system and their effects on the assessment of energy performance of the building and the associated costs of construction and operation. Alternatives for the design of a flat roof with a vegetation layer are also chosen in the construction solution of the building. The first part of the diploma thesis deals with the general requirements for the design and assessment of energy performance of buildings. The second part describes the individual options of the selected contact thermal insulation system and variants of flat roofs with a vegetation layer. In the next part, the budget for individual variants of thermal insulation is solved and the price of all variants is determined. The last part demonstrates the assessment of all variants and the overall economic evaluation with the selection of the best variants. For all variants, the time for which the investment will return is evaluated.

The diploma´s thesis deals with cutting beams technologies. It shows the current knowledge of these cutting methods, their possibilities and applications. The practical part rates benefits of replacement water jet with laser from economic and technological perspective.

The topic of the diploma thesis „ The impact of executing new thermal insulation on an administrative building in Blansko on the expenses associated with its operation“ is a draft and appraisal of four variants of thermal insulation of the building (EPS, EPS G, Mineral wool, Phenolic foam). It deals with an actual building situated in Blansko. All the variants are projected according to the same technical specifications (thermal transmittance) and their thermal parameters, technical parameters and the rate of return have been assessed. The assessed building (The A building) is at rectangular shape. It has six above - ground floors and a basement, it contains mainly administration sites. The construction system is concrete frame, which has curtain wall made of perforated blocks with thickness 250 mm. The building has got reinforced concrete floors, the roofing is made of double-skin roof construction. The supply for heating is a separate gas boiler room.

The thesis deals with the assessment of the current proposal for pension envelopes along with proposing alternative plans with emphasis on reducing heating costs. The first section describes the types of buildings according to heating demand and output energy performance of buildings. Work also deals with a list of different variants of thermal insulation materials and design options outer insulation of the building envelope. It outlines fire characteristics of building materials and options of construction budget. The second part is devoted to a specific pension house in the Old Rejviz for which there are designed in three variants of insulation. These variants are then reviewed in terms of thermal insulation. Through research will bedetermined price of implementation of proposed insulation options together with the costs of operation of the pension. The conclusion is to evaluate each proposed version of insulation of the building envelope associated with the economic return on investment.

This thesis solves the problems of efficiency of investment injected into the reconstruction and the new building. The existing construction with its planning conception and technical solution defines clearly the edge conditions which depends on the rang of the reconstruction. But on the other hand the architectural solution of the new building is determined by the size and shape of the area. And in addition to that i tis necessarity to také into account also the costs of removal of the existing building. In the first part of the thesis the advantages and disadvantages of both variations are compared as well as the factors affecting their prices and then also the problems of the budgeting and the legislation applying to this subject. The second part of the thesis solves the question i fit is more advantageous to use the existing building of the basic school in the vallage of Hrubá Vrbka and to convert it into the community centre for seniors or if it is more advantageous to pul lit down and build a new building which will correspond with its character to the planned utilization. The costs of both variations are expressed numerically in the detailed expenditure badget. The return of investments is calculated, the comparison of both variations is given in the conclusion.

The aim of the thesis is the economic evaluation of return of the different variants of thermal insulation for residential building in Slavičín. In the first part are described the topics, which is related to the issue. Further, it is written the entire range of insulations, which currently are appear on the domestic market. In the practical part is described the residential house and are performed by the proposals of the variants of thermal insulation. Further, they are processed energy performance certificates for buildings, the cost to implement the options chosen. In conclusion, the evaluated individual variants and determined their economic return.

The aim of the thesis is a design of the best energy measures for a family house. At first there is carried out an energy assessment of the building. According to results of that survey there are drawn up some variants of measures. Furthermore, based on energy assessment results there is elaborated a project for reconstruction of the heating.

The thesis deals with energy simulation of a solar energy system in a low-energy family house with warm-air heating. The simulations performed resulted in the assessment of the energy contribution of four solar systems with different types of collectors. The profitability and return of investment for the particular system have been evaluated based on investment costs and the savings gained. The theoretical part includes an introduction to the solar energy field, solar panel systems and the passive house concept. The practical part is devoted to description of the simulated object models as used in the TRNSYS environment, the simulation results evaluation along with the assessment of the economic return on investment. The conclusion recommendations regarding a suitable type and size of the solar panel with respect to the economic criteria chosen are given.

The task of this diploma thesis is to suggest insulation of chosen building and evaluate difference of operation costs before and after finishing the insulation. The economic return of the investment will be focused as well.

The thesis contains is familiar with the issues of renewable energy and global warming. Assessing the use of these resources in households in the Czech Republic. The selected family house, perform measurements on the existing heating system. In conclusion, there is suggestions for optimalization system houses, the possibility of linking the with renewable energy sources and an assessment of economic turn.
