Acquisition and operating costs of a selected building
Janků, Tereza ; Labudek, Lukáš (referee) ; Tichá, Alena (advisor)
This Diploma Thesis is focused on initial and operating costs. At first we calculated price for all building and for its other parts, which was calculated by program used for budgeting. After that we calculated partial costs which were done only for specific parts of the construction. These parts were changed and due to these changes we were finding out differences in heat losses and initial costs. Than for individual rooms we were defining heat losses. In this rooms, radiators were designed to cover its heat losses. By summarization of all heat gains we find out boiler´s power and this boiler was used in our building. After that we calculated initial costs for heating system includes radiators and boiler. In the end we compared both kinds of heating systems due to one year operating costs. Results were used for defining final heating system which is the most economic efficiential.

Controlled dehumidification in summer season
Voleš, Jakub ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
The subject of the diploma thesis is the design and the assessment of two variants of existing HVAC system, that serves the microelectronic laboratory premises of GL Electronic company, which are situated in JIC INMEC center. The aim of the designing process is to find the optimal solution of the problem, which is concerned of excessive air humidity gains in the clean rooms. The first proposed approach is the installation of controlled dehumidification in the form of direct cooling into the yet existing device. The second considered approach is a complete deconstruction of implemented air conditioning unit and subsequent reinstalling of the brand new unit, which would meet all the requirements. Both two variants will be in the beginning outlined in a form of pre-study, selected option will be later on processed as project documentation for construction. The winning solution will be designed in the way that will satisfie the criteria of hygiene, function, and economy. The next section of the text will be dedicated to the research regarding the topic of the physical nature of air humidity, of the transportation of humidity, dehumidification of the space, also. Last but not least, the heat recovery efficiency will be measured (in the form of thermal glycol tubes). The experiment provides evidence of the system's real-time performance.

Analýza finančních nákladů pořízení rodinného domu na bázi dřeva dle cenových soustav
Dušek, Václav
This bachelor thesis deals with the analysis of the cost of acquisition of a family of wooden house from a financial point of view. For the determination of the amount of the cost of construction has been used softwares BUILDpower S and Kros 4 applying when calculating the cost of building structures according to their own pricing systems. Processed budgets structures were compared with each other and used to assess the budget offered by the company. The obtained data have to inform the prospective investor about the hidden costs in the acquisition of the building and also offer information about software for budgeting available on the Czech construction market.

Functional parts valuation of the building
Ševčík, Jaroslav ; Nový, Martin (referee) ; Marková, Leonora (advisor)
Diploma thesis deals with comparing of current awards by Classification of building structures and works and awards by Functional parts. It is possible to calculate Building life cycle costs by Functional parts. This is definately the advantage of the system because the calculation cannot be done by Classification of building structures and works. A new law on public procurement deals with Building life cycle costs as an evaluation criterion. So it is recommended to use Functional parts awards. The other goal of the thesis is to find bridges between Functional parts and the issue of BIM. BIM is a trend of global construction industry.

Household heating systems
Ševčík, Ondřej ; Bok, Jaromír (referee) ; Bartošík, Tomáš (advisor)
Main goals of this bachelor thesis are economic evaluation of four chosen technologies of heating, and heating system design. Introduction deals with problem of heating in a family house, types of heating systems and main influences affecting the choice of heating system. The third chapter discusses main components of heating systems. Each component of the system is characterized and described. The most important parts include heating source, which are divided by type of fuel. The fourth chapter describes other possibilities of austerity meassures, which reduce heat loss and heating costs. There is a mention about government subsidies. The fifth chapter shows the shares of different heating sources, that are used in residential houses. In the last chapter, the computation of heat loss in the particular object is done. Based on the heat loss computation floor and radiator heating system is proposed. Four heat sources are chosen for the object (gas boiler, heat pump, biomass boiler and electric boiler with acumulation tank) and the purchase and the operating costs are computed. Conclusion of the chapter is devoted to the economic balance of the four heat sources and their comparison in the return of investment.
