Influence of Insulating a Building for Family Holiday on the Expenses Related to its Operation
Hanyk, Tomáš ; Hrdlička, Tomáš (referee) ; Čech, Josef (advisor)
This diploma thesis deals with the impact of thermal insulation on expenses relateted to the operation of the weekend house. Theoretical part describes options of thermal insulation systems, insulation methodes, describes structural prices and costs. Practical part of this thesis describes heat costs on specific weekend house situated in Karlovy Vary region. Thermal insulations are designed in three different variants. Calculation of costs of every designed insulation systém is included in this thesis. In next part of thesis is calculated return of investment for every designed solution. In conclusion of the diploma thesis are compared impacts of thermal insulation on expenses ralated to the operation of the weekend house.

From a Dumb Boiler to a Smart One Using a Smart Socket
Grünwald, Adam ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
The goal of this thesis is to extend a smart home by a smart boiler created from a dumb one with help of a smart plug and two temperature sensors for measuring values in a boiler. This smart boiler will be able to adapt to the household's schedule of using hot water using a learning algorithm, which uses historical data of hot water consumption measured on the boiler. Heating to higher temperature is happening before expected consumption or on request, which is represented as a special event in Google Calendar. The boiler can be either turned off with help of Google Calendar, which can be used when the whole family goes on holiday and it isn't needed to heat the water in the boiler. Programs for collecting and evaluating data, managing the heating of boiler, the database, and service showing statistics, run on a laptop in a local network. The main benefit of the thesis is creating a device, which can adapt boiler to smart home and reduce electricity costs on hot water heating by more than 30 %, which on 80 l boiler represents savings of more than 130 Euro per year.

Energy assessment of civil buildings
Slovenčíková, Iveta ; Vendlová, Lucie (referee) ; Horák, Petr (advisor)
The aim of the thesis is the energy rating of buildings. The introduction included the issues of the topic, including normative and legislative regulations, process energy performance certificates along with energy audits for residential building. The object is evaluated in terms of energy, economic and environmental. Within the energy audit was designed and evaluated austerity measures.

The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation
Machová, Petra ; Kosová, Jaroslava (referee) ; Čech, Josef (advisor)
The topic of the diploma thesis „The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation “ is a draft and appraisal of four variants of thermal insulation of the building. The thesis deals with the assessment of the current proposal for apartment building envelopes along with proposing alternative plans with emphasis on reducing heating costs. The first section describes the types of buildings according to heating demand and a list of different variants of thermal insulation materials. The second part is devoted to a specific apartment building in the Ústí nad Labem for which there are designed in four variants of insulation. The work includes thermal assessment in original condition and the assessment of new condition modified by adding thermal insulation. Through research will bedetermined price of implementation of proposed insulation options together with the costs of operation of the apartment building. In conclusion, the diploma thesis evaluates the payback period of insulation.

Energy optimization of the administrative building
Černý, Tomáš ; Horák, Petr (referee) ; Adam, Pavel (advisor)
The diploma thesis deals with the energy audit of administrative building. In the theoretical part I described the heat pumps. In a calculated part I proposed austerity measures and created of them saving variant. I chose the most suitable variant and assess it from an economic and ecological point of view. In the third part, I use the calculation program to optimize the building.

Design of a drying device for wood-processing industry
Vach, Tomáš ; Hrázský, Jaroslav (referee) ; Otáhal, Jan (advisor)
The thesis considers a stabilization of temperature of a wood fiber during production of medium close fibre boards MDF in a wood-processing industry. The original purpose to solve energetic optimalization of a kiln dryer has become a serious problem. It turned out that production suffers with a big heat loss which results in big heat loss gained during a kiln drying. Primary aim of this thesis is an examination of a cooling effect of environment on chosen parts of a production line and suggestion of acceptable proceeding to minimize heat loss and to rise temperature of the wood fiber to required temperature. Solution is aimed on the section of a production line between drying equipment and press. First part of the thesis introduces technology of production of fibre boards, introduction to heat transfer problems and also basics of computer modeling of heat flow and transfer using CFD simulation. The next part includes an evaluation of the heat loss of chosen parts of the production line in a current working condition and its comparison with computer simulations. Verification of accuracy of the results while using both approaches to solution is a first step to the improvement of the current situation. It is possible to use the verified calculation model for the following solution of effects on convective and radiation heating of a wood fiber layer. An important factor in the last period of a calculation is a real temperature of the fiber board-mat at the entrance to a press. The higher entering temperature in a set temperature range is reached, the lower time needed for pressing will be and simultaneously the whole industrial process will be cut short. The solution of a problem leads to an achievement of an energy saving and should become a solid basis from which it would be possible to evaluate an improvement of production of MDF boards. The conclusion of the thesis includes an analysis of findings which refers to a heating of wood fiber and it’s effectiveness for a practical use.

Architecture in landscape - Winery
Sáčková, Veronika ; Dýr, Petr (referee) ; Urbášková, Hana (advisor)
The purpose of this master’s thesis was to design an object situated on South Moravia nearby the Nove Mlyny dam with the view at the Palava Hills. The house is designed as extremely environmental friendly and energy saving in „A“ category according to the SEN-scale of building energy demand. Water purification and water management are part sof the ecological koncept. The primary target of the building is a wine production. It concerns grapes stemming, pressing, fermentation, aging, bottling and bottle stocking. One integral part of the building is an accomodation for 44-60 guests, who have the degustation room, restaurant and natural pool at hand. One last part is the CHKO Pálava information centre where i tis available to get information, internet access, or to use the library or lecture hall.

Energy Audit
Hrazdira, David ; Vyhlídalová, Karolína (referee) ; Horák, Petr (advisor)
The theme of this master's thesis is the elaborating of an energy audit according to the valid legislation in the Czech Republic a five-storey apartment building. The master's thesis consists of three main parts. Theoretical, Computional and Energy Audit. The theoretical part focuses on the theme of solar thermal collectors. In the calculation part, the energy consumption of the assessed object is analyzed in both the initial and the new state. The energy audit is drawn up in accordance the Decree number 480/2012 Sb. in the current version.
