Passive houses and their costs
Davidková, Zuzana ; Vaňková, Lucie (referee) ; Kocourková, Gabriela (advisor)
The bachelor thesis is about the costs of construction and operation of a passive house. It compares the costs of construction and operation with a dispositionally identical building in the existing standard and determines the payback period of the investment. Terms such as passive house, energy performance of buildings, heat losses and heat gains are defined. Then the creation of prices in construction, cost calculations or budget indicators are elaborated. The aim of the bachelor thesis is to quantify the higher investment costs of a passive building, its savings in the operational phase and evaluation of the payback period of the investment.

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.

Possibilities to reduce energy consumption of objects with controlled indoor temperature
Karmín, Luboš ; Čermák,, Jan (referee) ; Šťastník, Stanislav (advisor)
The field of a research of this diploma thesis is building with controlled internal temperature. The research is focused on main heat fluxes at this type of buildings and how it contributes to the energy consumption of the building. The main objective of the analysis is heat loss caused by heat flux through the building envelope and air exchange at the building. As next it is described heat gain resulting from the operation inside of the building. To obtain the results of the research part is used software on the platform Delphi Pascal, temporarily called SIM_Chlad. The aim of this computer modeling is non-stationary heat fluxes from the mentioned heat sources in the building. The computed heat balance analyzes the energy consumption of the building for a period of one year. The diploma thesis evaluates impacts reflecting local weather conditions, the structural system of the building and the operation in the building. A cooling machinery analysis is not the subject of the research at this diploma thesis.
