Assessment of the economic efficiency of low-energy and passive house
Maixner, Lukáš ; Klímová, Lenka (referee) ; Vaňková, Lucie (advisor)
The aim of this diploma thesis is to assess the economic efficiency of alow-energy and passive construction. This paper presents problems of lowenergy and passive construction, their individual characteristics, classification, construction materials, evaluation methods and opportunities for economic assessment due to the investment costs of implementation objects. The main practical part focuses on comparing the investment and operating costs for the construction of a standard, low-energy and passive house. Together with this are processed simple labels building. The out come of this diploma thesis is the calculation of returnability increased by the initial investment in the construction of a standard, low-energy and passive house.

Evalution of Economic Efficiency of EPC Projects
Vlčová, Zuzana ; Šourek, Bořivoj (referee) ; Korytárová, Jana (advisor)
The issue of energy saving building is a current topic of today. The increasing costs of operating buildings reduce economic efficiency of the organization operations. A large part of the operating cost is energy cost. An effective tool for improving the energy performance of buildings is an EPC method. The implementation of energy projects through EPC is offered by Energy Services Company. This thesis evaluates the economic efficiency of the project implemented by the EPC and analyses its risk factors. The subject of EPC project is modernisation of an energy sector of a hospital building. The economic efficiency of the project is interpreted on the basis of economic indicators Net Present Value, Internal Rate of Return and Profitability Index. There was also performed Monte Carlo simulation supported by Oracle Crystal Ball software within the analysis of risk factors for the project.

Economic analysis of building optimization
Pospíchalová, Barbora ; Zelníčková, Aneta (referee) ; Vaňková, Lucie (advisor)
The Master’s thesis deals with the energy savings of a prefabricated house. In the theoretical part, the issue of investment and risk management are first dealt with. Afterwards, the thesis deals with large panel construction in the Czech Republic, energy performance of buildings, heat losses, and especially methods for invesment appraisal. The main objective of the thesis is the economic analysis and the life-cycle analysis. The case study deals with the calculation of saving on heating the prefabricated house after its refurbishment and calculation of economic indicators.

Assessment of investment in heating house
Fodor, Ján ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
The bachelor’s thesis focuses on the assessment of individual investments for reducing the costs of heating a house. Firstly a heat loss of building was calculated according to norm ČSN EN 12831. Then were proposed some steps to save heating costs. Finally, it was in thesis economic confrontation individual’s steps for decreasing costs and their mutual confrontation.

Cost optimization of the operational phase of buildings
Kleinerová, Jana ; Dostál, Jan (referee) ; Výskala, Miloslav (advisor)
The thesis discusses the operating costs and the possibilities for their optimization. Specifically, it focuses on one of the greatest possible operating costs and it's heating costs. In the first part of the thesis are defined in general expenses, the price and the production, operating costs, optimization of these costs, life cycle of buildings and technological methods to improve the thermal and technical properties of the object. Finally, the theoretical part describes the terms for calculating the energy performance of the building and the payback period, which evaluates the effectiveness of investments. The practical part is assessed according to specific building energy performance, and especially in terms of its demand for heating. The building is designed for six variants of insulation, which is again judged on their energy performance. Subsequently these measures for better thermal insulating properties of the object assessed according to their cost efficiency and return on investment of individual variants.

Technology solution for energy savings in industrial processes
Cyž, Antonín ; Miklas, Václav (referee) ; Konečná, Eva (advisor)
This bachelor thesis is a search of known technological solutions for energy saving in industrial processes. The first part contains a description of the methodology for the analysis of energy consumption in the company. The first part also solves some of the statutory obligations of an energetic area in companies. Then follows a description and possible use of individual technological devices. The theoretical part of the work evaluates and describes the possibilities to increase the energy efficiency of an industrial laundry. Finally, the economic – energy balance of a specific operation is analyzed, including the evaluation of the financial return on investment.

Assessment of options to reduce energy consumption in industrial areal
Křesťan, Jan ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma thesis is assessment of options to reduce energy consumption in industrial areal belonging to Fritzmeier company. This thesis is divided into three parts. In the first part there is analysis of electrical energy and natural gas consumption in considered industrial area based on data from energy audit. The second part consists of short theoretical elaboration of cogeneration and cogeneration technologies, design of five variants of use of cogeneration units with combustion engine running on natural gas and evaluation of proposed variants. Third part of this thesis is about modernization of lighting system in small section of assembly hall. In this part parameters of new LED lighting system for selection are set, based on theoretical elaboration of LED problematics and five variants offered by specialized companies are evaluated.
