Thermal Insulation of Apartment Buildings: Decision-making Process and Effect on Energy Savings
Častorálová, Lucie ; Ščasný, Milan (advisor) ; Chytilová, Julie (referee)
Thermal Insulation of Apartment Buildings: Decision-making Process and Effect on Energy Savings Abstract In order to lower the emissions of green-house gases it is necessary to explore the wide range of the energy efficiency options. This thesis attempts to analyse the effect of thermal insulation installed in the multi-family apartment buildings during the period of 2006-2012 in the Czech Republic. We also investigate whether providing governmental funding further improves energy performance of the insulated apartment buildings. In addition, we examine the collective decision-making processes of members of the multi-family apartment building associations, including their attitudes towards thermal insulation of their houses. The basis of this thesis is the econometric panel data model (with 45 apartment buildings and their energy consumption before and after the insulation) evaluated by the fixed effects method with cluster confirming that the insulation, investments and public funding had all significant and negative impact on the energy consumption in the buildings, when energy consumption was adjusted for weather conditions. After the analysis it was concluded that the more the owners invest in thermal insulation, the more they will save in the long run. The governmental funding led to even greater...

Resource optimisation in the indoor aquaponic farm
Ondruška, Vojtěch ; Touš, Michal (referee) ; Teng, Sin Yong (advisor)
Energetická náročnost a ekonomická životaschopnost jsou často skloňované pojmy spojené s aquaponickým způsobem produkce potravin. Tato práce si klade za cíl nalézt opatření, která by zvýšila ziskovost podnikání v oblasti aquaponie a zároveň by snížila energetickou náročnost procesu a spotřebu dalších zdrojů. Součástí práce je následné ověření vybraných opatření na zkušební aquaponické farmě. K vyřešení otázky úspory energie a vody byly použity optimalizační metody vycházející z procesního inženýrství. Pro účely automatického monitoringu růstu rostlin, jakožto hlavního zdroje příjmů v aquaponii, byla využita technologie počítačového vidění. Za využití optimalizační metody zvané P-graph, integrace procesů a hledání procesních alternativ bylo nalezeno nejlepší možné uspořádání procesní sítě, které vykazovalo více než devítinásobný čistý roční příjem ve srovnání se současným uspořádáním procesních zařízení v aquaponické farmě. Dalších úspor energie a vody bylo dosaženo instalací reflexních fólií na okraje pěstebních boxů a dalším využitím odpadní vody z aquaponické části farmy v hydroponické sekci určené k pěstování sazenic. Tato opatření mohou napomoci aquaponickým farmám zvýšit konkurenceschopnost a snížit jejich dopad na životní prostředí.

Economic analysis of building optimization
Pospíchalová, Barbora ; Zelníčková, Aneta (referee) ; Vaňková, Lucie (advisor)
The Master’s thesis deals with the energy savings of a prefabricated house. In the theoretical part, the issue of investment and risk management are first dealt with. Afterwards, the thesis deals with large panel construction in the Czech Republic, energy performance of buildings, heat losses, and especially methods for invesment appraisal. The main objective of the thesis is the economic analysis and the life-cycle analysis. The case study deals with the calculation of saving on heating the prefabricated house after its refurbishment and calculation of economic indicators.

Reducing energy dependence of block of flats
Bouchal, Patrik ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
Bachelor thesis is focused on the assessment of energy self-sufficiency of block of flats. The introductory part deals with the block of flats itself. In the second part, it is thoroughly discussed whether there is sufficient amount of rainwater falling on the roof of the huse and it’s further use. The third part deals with the use of photovoltaic panels.

Energy-savings of a residential building
Michek, Jan ; Výskala, Miloslav (referee) ; Vaňková, Lucie (advisor)
The thesis focuses on energy savings of an apartment building. Firstly, the basic terms concerning apartment building and their costs are explained. Secondly, the thesis looks into energy efficiency of buildings, possibilities of energy savings and methods of economic evaluation of investments. The thesis sets the goal to evaluate current state of a selected apartment building from the perspective of energy efficiency and to propose possible energy saving measures. Lastly, the thesis aims to evaluate proposed measures from economic perspective and the perspective of energy efficiency.

Innovative Financial Instruments: An alternative to traditional grants
Jelínek, Tomáš ; Teplý, Petr (advisor) ; Víšek, Jan Ámos (referee)
Innovative financial instruments in the Czech Republic and their hypothetical use in the field of energy efficiency are analysed and assessed in this thesis. We address lim- ited awareness about multiple benefits of energy efficiency improvements and also emerging innovative financial instruments that are promoted by the European Com- mission as a way to multiply impacts of limited public budgets. Then we identify a suitable segment, Czech residential housing stock and public support of insulation, and compare several forms of possible public support in this field. As the main driver of space heating costs, we predict the future development of heat prices, and assess po- tential energy savings resulting from renovations. Finally, we assess and also simulate the potential of such an initiative and identify four suitable settings of the innovative financial instrument for a majority of stakeholders. Our findings support an idea that this innovative financial instrument offers a valuable alternative to traditional grants. It also suggests that such an initiative can be interesting for a private sector as well as a public sector, with benefits to public budgets, equity investors, households and many other stakeholders. Moreover, this initiative can be sustainable in the long run. JEL Classification G23,...
