Úspory elektrické energie ve zpracovatelském průmyslu
Pešák, Jiří
This thesis features an overview of technologies that convert various forms of energy into electrical energy, and brings a description of a transmission system. Current energy situation in the Czech Republic is evaluated and views for the year 2014 are predicted. Second part of the thesis is focused on the energy evaluation of the manufacturing enterprise model. On the basis of all the information obtained, possible measures to reduce the final electricity consumption of the factory are suggested.

Systems reducing the energy dependency of buildings
Mařák, David ; Köbölová, Klaudia (referee) ; Kudela, Libor (advisor)
This thesis focuses on systems that reduce the energy dependence of buildings, such as heat pumps, photovoltaics, heat recovery, and the utilization of geothermal energy. The main objective of this work is to analyze individual methods and technologies aimed at optimizing energy efficiency. The thesis explores the impact of these systems on the sustainability and ecological footprint of buildings, combining a theoretical overview with practical cases to provide a comprehensive perspective on the subject.

Comparison of energy consumption of selected wastewater treatment plants
Bodnar, Maryna ; Mergl, Václav (referee) ; Repková, Martina (advisor)
The aim of this final bachelor's thesis is to compare the energy consumption of two wastewater treatment plants. One wastewater treatment plant is located in the Czech Republic and the other in Ukraine and both of them receive an input of wastewater corresponding to the category of 10 000 – 100 000 equivalent inhabitants. The thesis described the wastewater treatment processes, their energy intensity, legislation related to wastewater treatment and energy intensity. Both WWTPs were compared with respect to their power consumption and their efficiency. Based on the obtained data, the processes that consume the most electrical energy were identified to ensure sustainable and efficient operation of the WWTPs.

Single-family house in Kostníky
Hodková, Zuzana ; Jechová, Marie (referee) ; Ostrý, Milan (advisor)
This bachelor’s thesis focuses into a detached near-zero-energy house in Kostníky. It includes documentation of architectural-structural design, including drawings, fire safety design, and building physics, along with documentation for building services safety. It is a two-storeys building for a family of four. The house is planned with two flat roofs and is based on a double layer of XPS panels. Reinforced concrete floor slabs and sand-lime masonry are used for load-bearing construction. Building envelope is insulated with polystyrene combined with mineral wool. The layout of the ground floor includes an entry hall with a walk-in closet, a bathroom, a study, a living area with a kitchen corner, a technical room, and a garage. The first floor is a private zone with children's rooms, a master bedroom, a bathroom, and a walk-in closet. Rainwater from the roof will be directed to a storage tank, where it will be reused with the assistance of a pump and a discharge device. Rainwater utilization is implemented for toilet flushing, while remaining water needs are supplemented from the public water supply. Wastewater is directed into the public sewage system. Ventilation in living areas is managed by an air handling unit and ceiling outlet. For heating, a ground-water heat pump is proposed to heat water for underfloor heating. Drinking water is heated by using a storage water heater. Electricity is supplied from the public grid and supplemented by photovoltaic panels. The energy performance certificate of the buildings was prepared by the Energetika software and the construction of the Detached house in Kostníky has been classified into class A (very efficient).

Energy balance in wastewater treatment plants
Novotný, Jan ; Raclavský, Jaroslav (referee) ; Hluštík, Petr (advisor)
This masters thesis is dealing with energetic evaluation of selected municipal WWTP – WWTP Polička. First chapter, introduction explains basic terms and goals of thesis. Second chapter explains energy audit, energy audit process its scope and contents. Third chapter deals with assesing life cycle using LCA (life cycle assesment). Fourth chapter deal with energy consumption at WWTP in Czech Republic as well as in the world. Fifth chapter describes technology of WWTP Polička and its fundamental objects. Sixth chapter is assesment of WWTP Polička from hydraulic point of view and assesment of selected machinery. Further there is summation of capital and operational costs followed by capital investment return.
