Analysis of heat consumption of building A2 in the area of FME BUT
Andrýs, Jan ; Štětina, Josef (referee) ; Katolický, Jaroslav (advisor)
Heat consumption of the building tells us how much heat we need to bring into the building to achieve the desired temperature. From that can be expressed the financial performance of heating of the building. This work deals with the analysis of heating of building A2 FSI VUT Brno. The analysis is done by the envelope method which considered only heat transfer to the surroundings and not inside the building, as they are irrelevant for us in this case. Another aim of this study is to evaluate the heat consumption after making adjustments to the building and evaluation of their returnability, depending on the change of heat consumption. All heat loss calculations were made according to ČSN EN ISO 13790 - Energy Performance of Buildings and ČSN 73 0540 - Thermal protection of buildings. considerated modifications of the building were the replacement of windows, insulation of building envelope and combination of the two previous adjustments simultaneously.

Design of a space and DHW heating system for a detached dwelling
Záboj, Jakub ; Pech, Ondřej (referee) ; Charvát, Pavel (advisor)
The thesis aims to propose a system for heating and hot water for a family house, according to drawings supplied by the building architect. At the request of the investor as the primary object will be considered a variant of underfloor heating. For comparing the heat loss, economic and possibly to State subsidies system selected will be processed by an alternative option to the ventilation air heating. Underfloor heating and hot air are among the low-temperature heating system, which can use low temperature heat sources, such as heat pumps. This assumption corresponds to investor requests, the source of heat in a family house with a heat pump and gas boiler. For hot water will be used as an alternative to a fireplace in the living room. To use the results of the thesis is to calculate the heat loss and heat, according to current standards include design and hot-water heating system including hot-drawing documentation. Finally, the economic evaluation of different alternatives in terms of investment and operating costs.

Thermal behavior and energy demands of low-energy office buildings
Pichová, Lenka ; Adam, Pavel (referee) ; Šikula, Ondřej (advisor)
The thesis deals with energy intensity of a low energy office building. In the thesis, em-phasis is put especially on the calculation of energy consumption for heating (cooling). The energy intensity of the building is determined and evaluated by four methods of calculation, which are compared with a valid certificate of energy performance of the building, which arose at the time of its construction. In the experimental part of the the-sis, the energy intensity of the building is compared to the actual energy consumption obtained by two experimental measurements in heating season 2012/2013. (The building is operating partly only). Different methods of solutions and valid legal regulations are elaborated in detail in the first part of the thesis.

Energy performance certificate of residential building
Němcová, Aneta ; Horká, Lucie (referee) ; Horák, Petr (advisor)
The bachelor thesis deals with the evaluation of the energy performance of the residential building in Letovice. The theoretical part is about thermal systems, especially the district heating. In the computational part, it compares the energy needs and flows of the baseline building with the newly designed state. The result is two passes of both states inserted into part C – the PENB project.

Energy performance of a civic building
Kořenková, Veronika ; Horká, Lucie (referee) ; Horák, Petr (advisor)
The goal of this thesis is to process three variants of energy performance certificate of the building with different heat sources. The building is in mountain area Bílá in Frýdek-Místek region. The thesis has three parts. First part is focused on literary research of heat pumps. Second, calculation part, describes three proposed heat source solution. First heat source is heat pump, second is pellet boiler and the last one is gas condensing boiler. All three variants are evaluated from the economic and ecological perspective. Last part of the thesis contains three energy performance certificates of the examined building.

Building Energy Performance Certificate
Farkhutdinova, Iuliia ; Horká, Lucie (referee) ; Horák, Petr (advisor)
In the bachelor thesis, the author focuses on the evaluation of an apartment building's energy efficiency in Ostrava before and after its reconstruction. In the theoretical part (A), the basic concepts of energy performance of buildings and the relationships between them are presented. In the calculation part (B), the comparison of the energy needs and an energy evaluation of the building before and after its reconstruction is provided. The assessment is performed by an energy performance certificate (PENB). Its part is the proposal of cost-saving measures for the current state of the building after reconstruction. The results consist of the three energy performance certificates presented in the part C.

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.

Home for the elderly
Remešová, Kristýna ; Struhala, Karel (referee) ; Jelínek, Petr (advisor)
This master thesis describes the design of a detached two-storey home for the eldery in Holešov with seventeen apartment units. The thesis includes architectural and structural designs, concept of technical systems and assessment of the building’s energy performance. The last part of the master thesis is about the vegetated roof water-balance. On the first floor there are facilities, canteen, a doctor´s office, a caretaker´s office, hairdresser´s and pedicure, buffet, tool storage and eight apartment units (1+kk – seven flats, 2+kk – one flat). On the second floor there are caregiver´s office, rehabilitation room, common room with library, and nine apartment units (1+kk – seven flats, 2+kk –two flat). The building has concrete foundations. Loadbearing walls are made of ceramic blocks. Floor structures and staircase are designed from cast-in-place reinforced concrete. The building is covered with a flat extensive green roof. The envelope is insulated with ETICS. There are nineteen parking spaces on the plot. The drawings were elaborated in AutoCAD software.

The design and evaluation of economic efficiency thermal insulation composite system of the house with a government grant in the CR and SR
Sobola, Martin ; Kocourková, Gabriela (referee) ; Vaňková, Lucie (advisor)
The aim of the master thesis is the assessment of the economic effectivity of thermal insulation with the state incentives in the Czech Republic and Slovak Republic. In the master thesis, the issue of investment, the possibilities of state funding of the construction industry, a detailed analysis of national funding programs aimed at promoting thermal insulation and the characteristics of thermal insulation contact system will be discussed with the focus on the design, realization management of the building and material possibilities. The output of the master thesis will be a proposal of a possible solution of thermal insulation contact system on a reference object. The financing of the investment will be compared in case of investment based on own resources or a bank loan, with the final assessment of economic efficiency with the use of insulation subsidy programs in the Czech Republic and Slovak Republic.
