Energy efficient building of a family house in Šumperk
Máchová, Klára ; Počinková, Marcela (referee) ; Blasinski, Petr (advisor)
The aim of this bachelor's thesis is to design a modern two-storey single-family house that minimizes energy consumption. The site is located in a new development area in Šumperk. The focus of the work is on designing an earth-sheltered home for a family of four and maximizing the usage of a steep building site. The first floor, accessible from the northwest, comprises service areas such as a garage, workroom, and utility room. On the east side of this floor, there is a bathroom, guest bedroom, and family room, which also serves as a home wellness area. The primary living area occupies the left part of the second floor and leads directly to the terrace. The right section of this floor is the rest zone, including a master bedroom with an en suite bathroom and a walk-in closet, two children's bedrooms, a bathroom, and a separate toilet. The load-bearing walls consist of aerated concrete blocks and sand lime blocks insulated with EPS. The horizontal structures are designed from in-situ reinforced concrete, ensuring structural integrity. A flat green roof helps the building blend into its surroundings and accumulates a significant part of the rainwater. The remaining water is stored in an underground tank and is used for garden irrigation and watering plants. The main source for heating, cooling, and hot water preparation is an air-to-water heat pump. During the day, it is partly powered by photovoltaic panels on the roof and remains connected to the grid. Building services include underfloor heating, cooling via a fan coil system, and mechanical ventilation with heat recovery (MVHR). The energy performance certificate, categorized as A, is part of the documentation.

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.

Air conditioning of the kitchen
Raftopulos, Patrik ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
This bachelor's thesis deals with the ventilation system for the functional unit of the kitchen in the hospital eating facility. The theoretical part is focused on methods of limiting the leakage of sensible and bound heat from cooking technologies into the room. In the calculation part, the design of hot air heating of the functional unit is solved. The overall analysis of the building and the division into individual functional units, the calculation of the heat balance of the functional unit, pressure drops, air flows, the design of the piping and the air handling unit are also solved. All elements necessary for the proper functioning of the entire system are listed.

Detached house, Červený Kostelec
Havel, Martin ; Struhala, Karel (referee) ; Kolář, Radim (advisor)
The aim of the bachelor thesis is the design of a nearly zero-energy detached house, which helps its inhabitants by its disposition and thought to maintain a healthy circadian rhythm. The building is located in Červený Kostelec. On the plot, the house is oriented with the idea of large solar gains, so with floor to ceiling windows facing south. The floor plan is T-shaped. the property has two floors and no basement. The load-bearing walls are made of aerated concrete. The floor slab consists of the Ytong Classic system slab. The open gable roof of the building is provided by truss wooden beams. On the first floor there is the main entrance, a large utility room, a separate toilet and a pantry. Then there is the entrance to the living room, which is directly connected to the kitchen. Children's rooms and bedrooms have east-facing windows. Rainwater from the roof is channeled into the storage tank. Excess rainwater is absorbed into the ground in the infiltration system. The property is connected to public sewer, electricity and public water supply. The house is heated and cooled by ceiling panels. The water is heated by an air-water heat pump. A fireplace insert with a hot-water exchanger is designed as a bivalent energy source. Photovoltaic panels on the roof are connected to batteries located in the utility room. Mechanical ventilation is proposed in the building. Total air exchange is 350 cubic meters per hour.

Energy systems of an energy-saving family house
Stanislavová, Sára ; Blasinski, Petr (referee) ; Šikula, Ondřej (advisor)
This bachelor's thesis deals with the design of a forced ventilation system for a family house at the implementation documentation level. Furthermore, it includes the design of underfloor heating/cooling and a multisplit cooling system. The heat source is proposed to be a ground source heat pump, which extracts heat using ground boreholes. As part of the Student Research Activity, a study was conducted during the heating system design to maximize the performance of underfloor heating through numerical simulation. The theoretical part focuses on heat pumps, specifically the ground source type.

Detached house in a suburban area
Cech, Aleš ; Kolář, Radim (referee) ; Jelínek, Petr (advisor)
This bachelor's thesis focuses on the design of nearly zero-energy house for a minimum of a five-member family. It includes parts A and B. Part A contains structural and architectural design, fire safety and assessment of building physics (acoustics, sunlight, and thermal assessment). Part B contains detailed design of air conditioning system, concept design of selected building services (heating, cooling, electrical installation, rainwater management) and the energy performance certificate. The house is located in the suburb of Znojmo, has two storeys, L-shaped floor plan, with a flat green roof and a car port next to the entrance from the northern side. The load-bearing walls are designed of large format sand-lime blocks with thermal insulation made of expanded polystyrene. The load-bearing floor and roof structures are designed as cast-in-place reinforced concrete slabs. The foundation slab is laying on foam glass granules. The source of space heating and DHW heating is a heat pump with a borehole collector. Space heating and cooling is provided by underfloor heating and fancoil units, simultaneous cooling regenerates the temperature of the soil in the borehole collector. Ventilation is provided by a mechanical, equal pressure system with heat recovery. The supply air is filtered and distributed by disc valves. There is a photovoltaic power plant on the roof with battery storage in the utility room. Rainwater is collected from the roof of the house, paved areas and parking shed roof stored in accumulation tank and used to water the garden. Excess rainwater is infiltrated in underground seepage.
