Renovation of a family house
Červinka, Michal ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
This master’s thesis is dealing with the plan of reconstruction of the house in an effort to get closer to "near zero building". Total heat loss along with calculation of the cost of the house operation and the energy performance of buildings were computed for the given house. Then we have enclosed suggestions of individual methods of building´s insulation (replacing of windows, doors and gates, insulation of exterior walls, roof and ceiling between floor and attic) and a draft of a new technical building services (forced ventilation with heat recovery, photovoltaic system and heat pump). Furthermore, the suitability of the original heating system was evaluated and the also the energy performance for the renovated building was analyzed during the reconstruction. An economic evaluation was calculated for each method of reconstruction, together with the new green subsidy programme. At the end of the dissertation is drawn up the economic evaluation of the whole proposed reconstruction, together with an assessment, what class of the building we have achieved according to its the energy intensity.

Metal waste processing system from cutting processes
Partlová, Veronika ; Osička, Karel (referee) ; Chladil, Josef (advisor)
Diploma thesis will be focuses on the processing of steel chips, explanation of general con-cepts, the division of chips according to their origin, their types and examples of some machines that are related to the chip processing system. It will also describe which law to follow when sor-ting waste like this, how to recycle it and how much this topic is connected with the ecological point of view. The second part of the work will be focused on the processing of the aluminium waste from the production of aluminium components. It contains a specific example of the calculation of a proposal to change the treatment of the waste and the return on investment in this change. The reason why to undergo this change is described too and in what way it will be beneficial.

Assessment of investment in heating house
Baláži, Martin ; Šnajdárek, Ladislav (referee) ; Baláš, Marek (advisor)
Bachelor thesis assesses the ways in which you can reduce the cost of heating a house. After the calculation of heat loss, there are chosen appropriate thermal-insulation applications to reduce heat transmission through the facade, roof and windows of the building. In the next step is chosen more efficient and environmentally friendly way of heating. Return on investments of selected applications, are shown graphically.

Assessing the Return on Investment in a Passive and Standard House
Krus, Tomáš ; Křivánek, Miroslav (referee) ; Hlavinková, Vítězslava (advisor)
The aim of this thesis is to compare economic investment in passive houses and conventional construction of a house. Furthermore, this thesis is focused on introducing problematics connected to construction of passive house, main characteristics, differences in used materials including review of advantages and disadvantages of their implementation. Assessment is based on return ability of initial investments generated by lowering operational costs. Main part of this thesis is aimed on compression of costs both before and in use of a house.

Comparative study of PV and heat pump in domestic energy supply
Kiša, Michal ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This thesis focuses on the utilization of a heat pump and photovoltaic system on specific residential house. It clarifies the basic concepts of the heat pumps, photovoltaics and their application on a house. In the description of the house there are mentioned basic parameters, a description of the existing system. There are heat demands calculations for house heating and water heating, calculated according to the theoretical values and these are compared with the actual values. The practical part deals with the design of heat pump and photovoltaic system. Also there are assesses of the purchase prices, the operational costs and the following investment returnability in comparison with a fireplace insert with accumulation storage and an integrated electrical heating element.

Energy Evaluation of Technical Services Systems
Cap, Petr ; Horák, Petr (referee) ; Vendlová, Lucie (advisor)
This Master’s thesis deals with the energy evaluation of existing buildings sports-recreational company complex in Brušperk. For this purpose provides a comparison of selected fuels as an energy source for the heating in terms of economy and their impact on the environment. In addition, provides an overview of existing legislation for elaboration of an energy audit. To complement shows the calculation of return on investment in solar panels on the roof of one of the objects. Calculation is based on the results of performed experimental measurement. Finally, the thesis presents a comparison of energy performance of buildings simulated in the Bsim software with reality.

Assessmen of ROI in a Passive and Standard House
Ruber, Lukáš ; Čech, Josef (referee) ; Hrdlička, Tomáš (advisor)
The thesis deals with the assessment of the return on economic investment in passive house compared to the low-energy (standard) house. The thesis deals with the issue of passive house, development, conception and division of structural parts including used materials. Their advantages, disatvantages and possibilities of use in construction are briefly discussed. The main part of the thesis focuses on the economic return on investment in passive house. Based on a detailed calculation, the costs for two buildings in low-energy and passive standards are quantified here. The passive standard is achieved by various design modifications. All this is supported by software calculation of annual energy consumption. The return on such an investment is then determined in more ways from this balance sheet, taking into account the evolution of energy prices.

The Influence of Insulating a Block of Flats in Trebic on the Expenses Related to its Operation
Sedláček, Jiří ; Kosová, Jaroslava (referee) ; Čech, Josef (advisor)
This thesis solves assessment and project insulation of a block of flats in Trebic, on the expenses related to its operation. In the theoretical part of thesis are given the reasons for thermal insulation of buildings, requirements in terms of energy intensity of buildings, static and fire safety for insulation of buildings. In the practical part, the current state of the block of flats is evaluated from a thermal-technical point of view, three new thermal insulation options are proposed, their evaluation and their return time calculated.
