Energy efficient family house
Halama, Daniel ; Vajkay, František (referee) ; Vlach, František (advisor)
The aim of the bachelor´s project is to design an energy-efficient family house. The house is located in Frýdlant nad Ostravicí. The building consists of 2 above-ground storeys and a garage. The house has 3 different roof levels. All roofs are flat. The main façade is oriented to the south. The main entrance to the house is situated on the south façade. The ground floor offers spacious living area, that is connected to the rest of the house by open corridor. On the ground floor there are also a study, utility room, bathroom, and garage. On the first floor there are master bedroom, kid’s rooms, bathroom, and the gallery above the staircase area. The building is designed on reinforced concrete foundation strips. The vertical load-bearing walls are designed from sand-lime blocks, insulated with a certified ETICS system. The horizontal load-bearing structures are designed from cast-in-place reinforced concrete. The object is connected to the following utilities – electricity grid, water main and sewage. The house is heated by air/water heat pump. The distribution is mainly provided by underfloor heating. The building is ventilated by the MVHR unit with the efficiency of heat recovery of 91 %. The distribution ducts are installed in the ceiling voids. The rainwater from the roofs is captured and stored in the 8,3 m3 underground water tank. It is used afterwards mainly for the flushing of toilets and irrigation purposes. The photovoltaic power station is installed on the roofs. The expected outcome of energy equals 7,55 MWh.

Single-family house in Troubelice
Nevěřilová, Hana ; Sukop, Lukáš (referee) ; Ostrý, Milan (advisor)
The aim of this Bachelor's thesis is to design a nearly zero-energy detachted house in Troubelice. First part is the concept of architectural and structural design. This includes drawings, fire safety design, energy performance certificate and building physics. The second part deals with the design of building services, encompassing the conceptual design of all systems. The plan of house building combines three rectangles shapes – detachted house, terrace and garage. The detachted house contains in the first floor entrance area, living room with dinning space and connected kitchen, master bedroom, toilet and bathroom. In the second floor, there are rooms for children, work room, bathroom and utility room. The unique feature of this house is the gallery, allowing connection people in the living space and the second floor. For contruction material I chose hollow core ceramic blocks for detachted house and gluelam for teracce and garage. Insulation is made from stone wool for its good technical properties. Furthermore I chose a simple plaster and saddle roof for the detached house and mono-pitched roofs for terrace and garage. Second part is the concept design of water supply and sewage system, electrical wiring, rainwater treatment, photovoltaic panels, air conditioning and mechanical ventilation. Furthermore, I explore the heating system more throughly. The house building is heated by under floor heating, which largely derives energy for heating hot water from the heat pump. The heat pump is divided into two parts - the outdoor and indoor units. It is connected with hot water tank and main manifold. It has 3 circuits. Two are for the floor heating and the last one for air heater.

The insulation is made of a contact insulation system from grey polystyrene combined with basalt wool. The ceiling structure above the first floor is made of a reinforced concrete slab. The roof is a gable roof with nailed trusses. The insulation is made of blown cellulose. Attached to the family house is a garage. It is built on a reinforced concrete slab, insulated with floor polystyrene. The walls are made of aerated concrete blocks. The roof is a flat green roof. Heating is provided by an air-to-water heat pump with an electric backup source. Hot water is stored is a storage tank and disturb through the hydronic underfloor heating system. Air exchange is provided by mechanical ventilation with heat recovery and an electric air heater. Photovoltaic panels with battery storage are located on the roof. Water from paved areas is collected and stored on a storage tank and used for irritation of greenery, excess rainwater is discharged into the rainwater sewer. The project documentation also includes an energy performance certificate classified as A – very efficient.

Detached house, Trojak
Žídek, Vojtěch ; Struhala, Karel (referee) ; Kolář, Radim (advisor)
The aim of this bachelor´s thesis is to design a family house with low impact on an environement. The thesis has two parts, while the first one deals with structural and architectonical aspect and the second contains solution of building services. The building is located near a forest with a plot featuring terrain with low slope. It is rectangular shape building with a pitched roof and two floors. On the first floor, there is a spacious open space with a kitchen and living room, a hall, a toilet and an utility room. Access to the second floor is through a staircase directly from the hall, where there is a master bedroom, two rooms and a bathroom. Load-bearing walls are designed from a timber frame structure with blown insulation between timbers. Foundations are designed of concrete slab insulated with foam glass. Ceiling on a first floor is from a timber with a suspended ceiling. Windows and entrance door have wooden frame with triple glazing. Pitched roof is a timber structure with a metal roofing. There is no connection to water infrastructure, so a well is designed for drinking water supply, along with a storage for rain water, used for flushing, washing clothes and watering garden. Floor heating and cooling are provided by an ground-water heat pump. Ventilation is provided by a ventilation unit with heat recovery, while fresh air will be supplied to living rooms and extracted from sanitary facilities. In the southern section, roofing contains integrated photovoltaic panels.

Single-family house
Kroupová, Julie ; Bantová, Sylva (referee) ; Krupicová, Jana (advisor)
The purpose of the bachelor's thesis is the design of a single-family house for four people. The first part of the project is documentation for construction of the building, the second part is focused on utilities – heating, air conditioning. The building plot is chosen in a small village Radvanice near the town Přerov. The building has two above-ground floors. On the first floor is garage connected to the entrance, which is located to the northwest, utility room, toilet, pantry, and the kitchen open-up to the dining room and living room. On the second floor is private space. There are two children's bedrooms, storage room, study room, bathroom with toilet and master bedroom with private bathroom and walk-in-closet. The building is based on plain concrete foundations. Structural system is masonry. The loadbearing walls are design from Porotherm – ceramics blocks filled with mineral insulation. The house is designed with air to water heat pump, underfloor heating, and mechanical ventilation with heat recovery.

Single-family house
Diblík, David ; Nespěšný, Ondřej (referee) ; Bečkovský, David (advisor)
The subject of this bachelor's thesis is the design of a new family house built from large-scale, multi-layered CLT panels, and the preparation of project documentation for the construction phase. The building is situated on a gently sloping site in the village of Račice near Dlouhé (Žďár nad Sázavou district). The concept and design respect the surrounding development and all mandatory municipal documents, particularly the zoning plan. The building consists of a single apartment, which, through its layout and material characteristics, corresponds with current technologies and elements in construction. On the ground floor, there is an entrance hall with a separate WC, a utility room, a living room with a kitchenette, and a bedroom with a separate dressing room leading to a private bathroom. The second floor is designed with two rooms each with its own dressing room, a study, and a shared bathroom. The family house is founded on strip foundations made of plain concrete, with vertical load-bearing and non-load-bearing elements made from massive wooden CLT panels. The exterior features include contact insulation using wood fiber insulation with façade plaster or ventilated wooden cladding. Horizontal load-bearing structures, such as the ceiling and flat roof with a waterproof membrane weighted down with washed river gravel, are constructed as ribbed ceilings with a limestone screed. The second floor is roofed with a gabled roof covered with aluminum standing seam panels, designed to accommodate photovoltaic panels and utilize alternative energy sources. The building is designed to have nearly zero energy consumption.
