The dissertation analyses a possibility to install a steam turbine for steam reduction in the heating plant with a combined cycle, Červený Mlýn. In the first part of this work the constituent parts of Červený Mlýn plant are briefly described. Basic information is included about two considered solutions to the steam turbine for steam reduction. Then the thermic diagram of the whole heating plant and the heat exchanger station itself is presented. On the basis of the given values of the heat required in the hydrothermal system, duration of the steam flow through both variants of the steam turbine for steam reduction is determined. The thermodynamic calculation of the steam turbine for steam reduction is aimed at determination of the power output and its comparison with the power outputs of the steam turbines for steam reduction considered. In the economical profitability calculation, basic economical quantities are given for both the solutions and the more suitable solution is recommended.

In conclusion, this thesis deals with energy and economic analysis of the proposed system, therein included various methods of assessing investment recommendations of appropriate processing methods and overall assessment of the subject.

e master's thesis clarifies the concept of trigeneration and the principle of absorbing cooling. Compare the advantages and disadvantages of this method of manufacture cool with compressor cooling. It presents an overview of the implementation of a developing cold absorption and performance. Acquainted with the types of absorption chillers of the two leading suppliers, their characteristics and existing applications of these refrigeration units in operation in the Czech Republic and abroad. It also assesses the possibility of using these units in conjunction with a cogeneration unit powered by internal combustion engine. It follows from the economic assessment of costs and income of the absorption chillers and compressor chillers and on concrete examples and an assessment of the effectiveness of the various options.

The subject of this thesis is to assess the economic efficiency of the investment project. The theoretical part focuses on the basic definitions related to investment decisions on the investment project and the project life cycle, cash flows and their predictions and recommendations to set them correctly, methods useful for assessing the effectiveness of the investment project and the indicators presenting the financial stability and feasibility of the project as well as factors affecting the overall investment decision, and finally the possibility of financing of the investment projects in the private sector. In the practical part there are the theoretical findings applied in the real investment project. Specifically, there will be analyzed the characterized investment project and its possible alternatives and finally made the assessment of economic efficiency.

Modern energy saving technologies are become increasingly mature, easier to implement and financially profitable. Both the European Union and the Swedish government have directives with goals regarding energy savings for the year 2020 and 2030. Here, making buildings more energy efficient plays a large role as around 40% of the total energy usage in Europe can be related to buildings. Constructing new, nearly zero energy houses is currently very popular, but as a vast majority of all buildings in a country like Sweden are older buildings, built before 1980, a majority of the used energy will come from these buildings. Hence, there is plenty of incentive for carrying out energy saving actions and investments in older buildings. From previous research and interviews with energy consultants, it can be concluded that energy saving actions are not being carried to the extent that is possible. This thesis aims to find out why this is and mainly what the main obstacles are when implementing energy saving solutions in older buildings. A case study, consisting of eight interviews with energy consultants and real estate owners was carried out in order to get an understanding of the current situation and the different stakeholders views on this issue. The results showed that, at least in the represented cases, there is a will among real estate owners for moving forward with energy saving. An understanding has also recently emerged where most real estate owners realize that there are great financial incentives connected to implementing energy saving solutions to current, older buildings. However, increased will of making a change has not yet resulted in a majority of buildings having installed energy saving solutions. One factor for this is that each building is its own individual case and therefore needs to be handled individually due to different conditions and are therefore suitable for different energy saving actions. Other factors include lack of technical and financial understanding among some real estate owners, slow decision making processes and ownership types. The research explores theories related to decision makings to provide a comprehensive overview regarding the current situation of energy saving in Sweden, as well as a contribution to the theoretical literature regarding decision making / Modern teknik inom energibesparing blir allt mer mognare, lättare att implementera och finansiellt lönsamt. Både den europeiska unionen och den svenska regeringen har direktiv med mål för energibesparing för år 2020 och 2030. Här spelar byggnader en viktig roll, då byggnader står för ca 40 % av den totala energianvändningen i Europa. Att bygga nya, nära noll energi byggnader är för närvarande väldigt populärt. Men i ett land som Sverige, där majoriteten av alla byggnader är äldre byggnader, kommer majoriteten av energianvändningen fortfarande från dessa. Därav finns det stora incitament till att genomföra energieffektiviserande åtgärder på äldre byggnader i Sverige. Från tidigare studier och intervjuer med energikonsulter kan det fastslås att energibesparande åtgärder ej genomförs i den grad som det är möjligt. Målet med denna rapport är att utröna varför det är så samt vilka huvudsakliga hinder som kan relateras till energibesparing i äldre byggnader. För att få en överblick av den befintliga situationen samt hur olika intressenter ser på denna fråga genomfördes en fallstudie bestående av åtta intervjuer med energikonsulter och fastighetsägare. Resultaten från studien pekade på att det finns en vilja bland fastighetsägare att gå vidare med energibesparande åtgärder. På senare tid har även en förståelse vuxit fram bland fastighetsägare där man inser att det även finns stora finansiella incitament med att implementera energibesparande åtgärder på äldre byggnader. Detta har dock ännu ej lett till att energibesparande åtgärder genomförts på en majoritet av befintliga byggnader. En anledning till detta är att varje byggnad måste hanteras individuellt då alla har olika förutsättningar och därmed lämpar sig för olika energibesparande lösningar. Andra faktorer inkluderar teknisk och ekonomisk kunskapsbrist bland vissa fastighetsägare, långsamma beslutsprocesser och ägarstrukturer. Studien nyttjar teorier relaterade till beslutsfattning för att ge läsaren en överblick av den befintliga situationen kring energibesparing i Sverige. I tillägg bidrar studien till den teoretiska litteraturen om beslutsfattning.

The goal of the thesis is firstly to get all the information about the initial state of solved block of flats, which is located on the street Merhautova 76/954 in Brno – Černá pole, in terms of constructions, energy consumption and initial state of heating system. In the second part of the thesis, where are discussed the possibilities of reduction of energy consumption, variant drafts of reduction of energy consumption and their financial costs and the choice of optimal variant. Third part deals with assement of solved block of flats in terms of sustainable built environment by using tool to rate buildings in terms of sustainable built environment - SBToolCZ, evaluation of possibility to use renewables. In the end are written summaries and recommendations.
