Study of the thermal insulation effect of thermally reflective insulations
Skříček, Darek ; Vala, Jiří (referee) ; Čermák, Jan (referee) ; Šťastník, Stanislav (advisor)
The dissertation on the topic Study of the thermal insulation effect of thermally reflective insulations is focused on the issue of measuring the thermal resistance R of thermoreflective insulations and determining the most suitable layer with the best thermal insulation properties. By measuring thermoreflective insulations on the Hot-Box measuring chamber, it was proven that higher values of thermal resistance R are always achieved with aluminum foil, which has the highest possible reflection of the radiant component of heat, i.e. the lowest possible emissivity on the surface. For this reason, the reflectance was measured on the Mid-IR Integrat IR ™ measuring apparatus. To study the thermal insulation effect of thermoreflective insulations, ten samples of these insulations with different compositions of aluminum and bubble foils are used to measure the insulation properties. The suitability of using thermoreflective insulation for building insulation was proven by measuring these foils.

Family house energy requirements audit
Halata, Maxmilián ; Hejčík, Jiří (referee) ; Fišer, Jan (advisor)
The bachelor’s thesis is focused to possibilities of using National calculating tool of buildings energy requirements according to Czech government regulation no. 148/2007 Sb. The tool was applied to calculate energy requirements of chosen family house. Several types of house modifications which can reduce energy requirements are proposed based on results of the audit. Each modification of the house is analyzed from the energetic, construction and economic point of view.

Study of utility properties thermal-reflective insulations in the buildings
Holeček, Dominik ; Skříček, Darek (referee) ; Šťastník, Stanislav (advisor)
The diploma thesis is partly dedicated to energetic efficiency of buildings and describes possibilities how to evaluate energetic efficiency of buildings in the Czech Republic. We also get to know with distribution of thermal insulators by material base and use in construction. There are also mentioned methods how to determine thermal insulations characteristics of heat insulations, so called heat conductivity coefficient. The last and the crucial chapter of theoretic part is dedicated to thermal-reflective insulations. There are mentioned some of the basic characteristics of insulations, material composition and heat transfer mechanism in their structure as well. Practical part describes measurement of thermal resistance of chosen samples of thermal-reflective insulations per measuring device on the principal of Hot Box method. In the next step was determined emissivity of aluminium foils which forms the surface of chosen samples of thermal-reflective insulations. In the end of thesis are defined possibilities of use thermal-reflective insulations in building structures especially in passive and low-energy buildings in climatic conditions of the Czech Republic.

Reduction in energy intensity of the public object
Michek, Jan ; Chovancová, Jitka (referee) ; Vaňková, Lucie (advisor)
The thesis focuses on increasing energy efficiency of a public building. Firstly, the basic terms regarding public procurements are explained in general. A specific area of public procurements, especially contracting public procurements of small scale are studied next. The following part of the thesis is dedicated to the basic terms in the area of energy efficiency of buildings. The goal of the thesis is to evaluate all the procurement procedures related to a concrete public procurement of small scale, to evaluate the energy efficiency of the building before the realization and to reevaluate the energy efficiency including monitoring of the building after the realization.

heating of the pedagogical advisory centre
Šrámková, Denisa ; Vendlová, Lucie (referee) ; Počinková, Marcela (advisor)
The bachelor's thesis deals with the design of the heating system of the pedagogical counseling center. The theoretical part of the work deals with the energy performance of buildings and a certificate of energy performance of the building. The calculation part deals with a separate design of the heating system and its partial elements. The calculation part also deals with hot water heating and heat accumulation. An air / water heat pump is designed as the heat source. The building is heated by radiators and underfloor heating. The entire technical solution is described in the technical report, including requirements for other professions.

Possibilities of drawing financial support to reduce the energy intensity of buildings
Felgrová, Nikola ; Kocourková, Gabriela (referee) ; Vaňková, Lucie (advisor)
This bachelor thesis deals with options for obtaining financial assistance in order to minimize building energy intensity. The first part is focused on clarifying the concepts related to the issue. This covers things like investments, loans, subsidy resources, and subsidy programs, among other things. The second section of the paper examines how a particular family house in the village of hudlice went about decreasing its energy intensity. Variations of funding for this construction project were presented based on available information on the availability of subsidy resources and the provision of custom loans

Thermal Insulation Effect of the Building on the Operation-Related Expenses
Skupa, Jan ; Klika, Pavel (referee) ; Čech, Josef (advisor)
The diploma thesis entitled The influence of building insulation on the costs associated with its operation deals with the design of several variants of building insulation, and subsequent evaluation based on a comparison of operating costs of individual building variants. The theoretical part deals with the history of thermal insulation of buildings, there are types of thermal insulation materials and variants of energy-efficient houses. Then the normative requirements, energy intensity of buildings and methods of thermal insulation of individual building structures are solved. Subsequently, the methods of economic evaluation of the investment and the method of compiling the general budget are addressed. The practical part contains a description of the construction and the proposed variants of insulation, including the calculation of costs, evaluation of the payback period of the investment and evaluation of the proposed variants.

The Influence of Insulating the Pensioners' Home in Šternberk on the Expenses Associated with its Operation
Ťuka, Jiří ; Trnka, Lukáš (referee) ; Čech, Josef (advisor)
The diploma thesis is elaborate in order to evaluate the economic returns of each proposed building insulation options for seniors in Šternberk. For the calculation use to secluded brick apartment building in the street Žitná. The theoretical section describes the types of buildings according to heating demand and a list of different variants of thermal insulation materials. The second part contains suggestions for building insulation in several variants. It worked certificate of energy performance of buildings, costs of proposed options and the costs of operating the apartment building before and after the insulation. Based on the comparison of results is elaborate economic returns for each of the proposed options.

SIMULATION OF ENERGY PERFORMANCE AND REAL OPERATION OF BUILDINGS
Šteffek, Libor ; Ingeli,, Rastislav (referee) ; Hirš, Jiří (referee) ; Ostrý, Milan (advisor)
This dissertation thesis primarily focuses on the experimental measurement of energy consumption of a given energy-passive family house as well as theoretical research in the field of energy calculations using computer simulations. The results of quasi-stationary and dynamic simulations, with varying computational and real-time climate data, are compared with experimental measurements. Using the dynamic calculation model, which was validated by actually measured data, the relationship between architectural design and the energy performance of the building was analyzed. The influence of selected different operating modes for heat consumption on heating, cooling, ventilation, and interior overheating is observed. The result of the mutual interaction of several input parameters of variant solutions provides the basis for optimization of the whole design.
