Low temperature heating with heat pumps
Bros, Miroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The master’s thesis deals with design and comparison of two variants of low temperature heating with radiant systems and heat pumps. Building is used for administrative purposes. The theoretical part describes the evaluation of heat pumps. The calculation part deals with the calculation of heat loss of the building, the design of the heating system, the hot water preparation system, the heat source, all necessary supplementary devices, and the calculation of yearly heat and fuel consumption for heating and hot water preparation of the building. Heating system consists of floor heating and ceiling heating. For hot water preparation an indirect fired hot water storage tank is designed. The source of heat is a cascade of two air/water heat pumps. Experimental part is focused on measuring and assessment of pressure loss, heat output and efficiency of radiant ceiling panel.

The design of ETICS using insulation core made of aerated concrete
Machala, David ; Zach,, Jiří (referee) ; Drochytka, Rostislav (advisor)
This thesis deals with theoretical suggestions of contact self-supporting insulation system with an insulating core made of porous concrete. The text prepared knowledge about ETICS system, the properties of porous concrete are thoroughly described, including the history and the most often used technology for production of porous concrete. The conclusion is made by comparison of economical and thermal insulation criteria using optimizing calculation and the applicability criteria of proposed ETICS are stated.

Residential units from natural materials
Lontrasová, Michaela ; Řehůřek, Ivan (referee) ; Výskala, Miloslav (advisor)
The aim of this bachelor thesis is to determine the costs of building a family house log cabin compared to the wooden building. The first part focuses on natural building materials. Their characteristics, applications and comparison with industrially produced building materials. The second part firstly describes various structures of selected family houses, wooden houses and log cabin in brief. Subsequently, the structure budgets are assembled, compared and evaluated their costs. The budget is based on a bill of quantities wooden houses insulated by straw bales. Finally the positive and negative characteristics of these houses are listed.

Energy assesment of single family house
Panovec, Jan ; Počinková,, Marcela (referee) ; Hirš, Jiří (advisor)
The aim of this bachelor’s thesis is to understand the nature of the energy assesment of building with low energy demand and energy-saving requirements. The calculations of energy intensity and experimental measurements of chosen parameters of inner microclimate in the building were done. Theoretical part includes requirements and principles of projecting buildings with low energy demand.

Optimization of Price of Building Object
Nyklová, Petra ; Witala,, Lukáš (referee) ; Kocourková, Gabriela (advisor)
This work deals with a price optimalization of a family house. The aim is to replace in item budget materials influencing construction price, the quality, however, being kept or improved. There have been chosen three budget items which are compared with alternative solution, considering their price and heat permeability coefficient. Final assessment focuses on either leaving or replacing the originally proposed materials.

Energy audit object for education
Ešpandr, Jan ; Vendlová, Lucie (referee) ; Horák, Petr (advisor)
The bachelor thesis deals with the assessment of the energy performance of the TJ Sokol Moravské Budějovice building. The assessment has been realized by the method of energy audit and energy performance certificate. The building has been assessed based on the energetic, economic and environmental aspect. As a part of the audit economy measures have been drafted and evaluated.

Cost analysis of passive houses and houses with zero energy demand
Gregovská, Kateřina ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The bachelor's thesis deals with the envelope structures of an existing family house, which is in a passive standard. The constructions being compared are therefore peripheral, floor and roof. The subject of this work is whether the proposed structure composition is effective, both in terms of heat transfer coefficient and in construction costs and speed. Alternatively, find a better possible variant of thermal insulation for already designed compositions of envelope structures. The work therefore compares different types and thicknesses of thermal insulation. The values of heat transfer coefficient, cost intensity and time intensity were used for comparison.

Heating of Family House by Heat Pumps
Sláma, David ; Moskalík, Jiří (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with heating of family house by heating pumps. The main task was to design a suitable heating pump for a chosen family house. Here is given the method of calculation total heat loss of building. Depending on the performance characteristics are compared two types of heat pumps, and will be selected the appropriate one. The last part compares the seasonal performance factors (spf) 3 and 5.

PCM-based heat and cold storage
Němec, Lukáš ; Ostrý, Milan (referee) ; Šikula, Ondřej (advisor)
In the first part of the bachelor thesis I will deal with the accumulation of heat and cold using materials with phase change and also the design of a PCM storage tank. The aim of my effort is to design the most ideal spacing of tubes in a given tank, so as to achieve the greatest possible heat capacity. I performed simulation experiments in CalA 4.0. The second part is computational, where I focus on the design of heating in the pension. I solve heating with an air-to-water heat pump. I designed solar collectors for hot water heating. The last and third part is the project, which contains the project documentation together with the technical report.
