Assessment of the Return on Investment in Insulating a Residential Building in a Selected Area
Vyhnálek, Václav ; Procházka, Pavel (referee) ; Tesařová, Zdeňka (advisor)
The diploma thesis deals with the impact of insulation of a residential building on the price of apartment buildings and the payback period of investments in thermal insulation. The theoretical part deals with the topic of energy intensity, methods of thermal insulation and valuation. In the second part of the thesis, the values of selected apartment buildings are determined by the direct comparison method and the time of return of investment in thermal insulation. In addition, the thesis deals with energy saving depending on thermal insulation. The aim of the thesis is to determine whether and how much will increase the price of an apartment house or housing units due to additional thermal insulation, what are the savings for heat and what is the period of return to investment.

Multifunctional house in Karlovy Vary
Růžička, Jiří ; Vlček, Ing Karel (referee) ; Vlček, Milan (advisor)
The project solves a multifunctional Duma building in a vacant lot, contemplated the construction site is located in Carlsbad, in the street Vyhlíce. This is a protected site spa. Part of the project's layout and structural design of the house. It is a six-storey house with an attic and a basement floor. It is designed as a free-standing in the gap as the final house. The layout is divided into two complete units with their own input. There are spaces for business and residential units for permanent housing. Part of the living area are also room house equipment. Inputs to both parts are wheelchair accessible. The house is not wheelchair The house is designed as a brick building of brick masonry Porotherm the module dimensions of 250 (125) mm with reinforced concrete ceilings. Roofed by a hipped roof. The house is located on a private plot of 519 m2 built-up area of 221 m2. The land is gently sloping. The main orientation of the building to the cardinal's east and west. The south wall is adjacent to the neighboring house.

Energy Intensity Reduction of a Professional Laundry Care Process
Bobák, Petr ; Klemeš,, Jiří (referee) ; Noskievič, Pavel (referee) ; Stehlík, Petr (advisor)
Doctoral thesis deals with professional laundry care process and reduction of energy intensity and use of other operational commodities used in the process. Professional laundry care process is a specific energy intensive process; its purpose is to re-establish original properties of the now dirty laundry so that it may fulfil its functions again. This is basically a recycling and regeneration process comprising many sub-operations. Key operation is washing of the laundry in a washing bath, which removes impurities from the laundry. This thesis describes the most common technology of impurities removal, which is washing in a hot washing bath in cooperation with mechanical work and detergents. However, all of the described procedures may also be applied on alternative technologies, such as ozone washing, washing with low-temperature enzymes and ultrasound. Water is applied in all these technologies as a soaking agent. Water must have appropriate properties and must be removed from the laundry after the washing process in subsequent operations (drying, ironing, and pressing). Theoretical introduction of the thesis describes professional laundry care process in detail, and continues with mathematical modelling of the process and its main sub-operations (washing, drying) using mass and heat balance, and data acquisition and their application in research and development. Thesis further describes design of information system on the basis of relational database controlled by web application. This system enables to organize data and information from various sources – measured experimental data, data concerning measurement devices, operational records of machines, etc. Thesis further proposes how to evaluate and reduce energy intensity of a process. Descriptions are validated by examples and case studies. Key section of the thesis is a chapter describing experimental infrastructure. This infrastructure integrates several instalments of laundry equipment and is a fully functional operation of industrial laundry facility with 500kg/shift capacity, which serves as a model of energy intensive process. Sophisticated infrastructure and data acquisition system allows measuring wide spectrum of physical entities and examining factors influencing energy intensity of processes, and relationships between these factors as well as effectiveness of various savings measures in real life facilities.

Anlysis of the Effect of Insulation on the Price of Flats in Žďár nad Sázavou
Dvořák, Jan ; Hlavinková, Vítězslava (referee) ; Kubičková, Veronika (advisor)
This thesis analyzes the impact of insulation on the price of flats in Zdar. In the theoretical part of the thesis deals with the theme of energy demand and pricing. The second part sets the prices of selected flats in different valuation methods, namely: direct comparison method, comparative method and cost method. Furthermore, the work deals with energy conservation, depending on the thermal insulation. The aim is to determine whether and by how much prices will rise flats due to the additional insulation, what are the savings in heat and what about payback to investment.

PENB Impact on the Price of Real Estate
Lukeš, Martin ; Lorencová, Marie (referee) ; Pertl, Marek (advisor)
This thesis deals with current topics of today, such as the issue of valuation of real estate and energy performance of buildings. The content is divided into a theoretical part where the first general and then specifically looks at the issue, and the practical part, which contains the calculations for determining the price of the selected house by direct comparison and cost methods by decree. It also specifies the energy performance of the house in its current state, and after the thermal insulation. Orientation also the return on the investments made from the perspective of the investor. The aim of this study is to assess the extent to which there is an increase in the price of a house due to the thermal insulation.

Analysis of the influence of insulation on the price of housing units in Opava
Adamus, Aleš ; Pertl, Marek (referee) ; Hlavinková, Vítězslava (advisor)
This dissertation analyzes the effect of insulation on the price of housing units in Opava city. In the theoretical part of the dissertation deals with the subject of appraisement, the energy intensity of buildings and technical-economic evaluation. In the practical part sets the prices of selected housing units by direct comparison, the comparative method by regulation and yield value. It assesses whether the possible range in the valuation regulations (5%) reflects the fact that the recognized building insulated in accordance to the current legislation. It detects the energy nature of a apartment building in which they are placed selected apartments. The goal is to determine a price increase of housing units due to insulation and evaluates the appropriateness and inappropriateness of buying from the investor's perspective.

Multi-purpose building
Miška, Tomáš ; Mátl, Miroslav (referee) ; Hlaváček, Pavel (advisor)
The aim of the master’s work is elaborated complex project documentation for new multi-purpose house in Staré Město pod Sněžníkem. The building combines retail stores with space for housing. Custom text labor is completed by annexes, which consists of drawing documentation, building alternative solutions, static calculations, fire safety and technology of the building. The subject of specialization is solving the water supply and assessment of reinforced concrete girder. The project is designed by using Allplan 2009, Scia Engineer 2009, Stavební fyzika and MS Office 2009 and is engaged in the design, construction and technical layout solution with respect to architectural page and possible savings operation of the buildings in relation to sustainable construction.

Masonry Block of Flats
Šotkovský, David ; Havířová, Zdeňka (referee) ; Lavický, Miloš (advisor)
This Master´s thesis is focused on block of flats project documentation, claims for fire safety and thermal and acoustic properties of structures. The brick building is detached and has three floors without basement. These floors are connected by a lift. The block of flats is based on the footings, external walls are insulated by a contact thermal insulation system. The tent roof is consists of truss in two levels. The building is designed for nine flats and one of these flats is wheelchair accessible. Truss design is also a part of the project.
