Energy efficient family house
Krumpolcová, Lenka ; Brzoň, Roman (referee) ; Vlach, František (advisor)
The aim of this Bachelor´s thesis is to design a nearly zero-energy detached house in Holešov, Zlín region. The house has two floors and a flat roof. The floor structure are designed as reinforced concrete. The foundation strips are designed from plain concrete, the vertical structural system is designed from ceramics blocs. The external walls are insulated with ETICS. On the first floor, there is a wind lobby, a dressing room with a laundry, a utility room, a bathroom, a guest room, a pantry, a living room with kitchen and a dining room. On the second floor, there is a bedroom, two children´s rooms, a bathroom, a separate toilet, a dressing room and a study. Space heating and domestic hot water heating in this house is provided by air-water heat pump. The building is heated by underfloor heating. Ventilation is mediated by a forced unit with heat recovery. Rainwater is collected from the roof and then drained into the storage tank. The water from the storage tank is then used for irrigation of greenery and flushing of toilets. Unused water will be infiltrated into the ground on the property. Photovoltaic panels are placed on the flat roof. On the basis of hourly calculations, the designed single-family house falls into the classification class ,,A - exceptionally energy efficient".

Zemánek, Jan ; Jechová, Marie (referee) ; Ostrý, Milan (advisor)
The goal of my bachelor’s thesis is to design a nZEB house for family of four. It is located on the edge of town Hodonín. The house has two floors with a one floor garage attached to the side. The first floor contains utility room, some storage area, kitchen to the north that is connected with living room and dining room facing south. The second floor than has two bedrooms facing south-east, study and master bedroom facing north-east and bathroom facing northwest. The roof of the house is flat with surface form waterproof membrane. Roof of garage is extensive green roof. The foundations of the building are reinforced concrete strips. Load bearing walls are masonry designed from sand-lime blocks with external mineral wool insulation. Horizontal load bearing structures will be made from reinforced cast on site concrete. Partition walls are planned to be from plasterboard. The main source of heat for the house will be air to water heat pump with performance of 8,02 kW and inbuilt electric insert to get temperature needed for floor heating. For hot water there will be separate hot water cylinder with volume 208 l and inbuilt electric insert. The ventilation system will be MVHR with air exchange of 310 m3/h and bypass system. The internal sewage system will be connected to the city sewer, while rainwater will be collected, used for watering garden, or infiltrated into the soil. For cooling external shutters will be enough.

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.

The walls are design from ceramic blocks and floor slabs are design from prefabricated beams and ceramic infills. The building envelope is insulated with mineral wool. Air conditioning in the house is ensured by a mechanical ventilation with recuperation. Waste water is directed into sewer system. Rain water is stored in an accumulation tank and from there into infiltration blocks, then water is also used for garden irrigation. Hot water is supplied by 200l hot water cylinder. Electricity is secured by photovoltaic panels with storage batteries and second source is public network. Heating is serviced by air-to-water heat pump and secondary source is fireplace with exchanger. Heat distribution is provided by floor heating system.

Detached house Prstne
Voženílková, Veronika ; Jelínek, Petr (referee) ; Kolář, Radim (advisor)
The aim of the bachelor´s thesis is to design a single-family house in a passive standard. The house is located in Zlín in the Prštné district. It is a square-shape two-story building with a porch and parking space for two cars. The object has a flat green roof and the balcony on the southeast is covered with bifacial solar panels. Beneath the balcony lies am unheated area, where the conservatory and two storage rooms are situated. This part of the house is excluded from the thermal envelope and helps the building to become more energy efficient. The service zone was designed to face the north while the private zones faced mainly the south and west. The masonry of the building is limestone blocks insulated by rock wool with a vented facade on the top. The house is powered by air-water heat pump and solar panels. Additionally, the building is connected to the grid to address any potential energy shortfalls. The comfortable climate inside the house is maintained by underfloor heating and mechanical ventilation with MVHR unit. The air in the house is distributed by a flexible duct. The rainwater from the roofs is stored in the water tank under the ground next to the house for garden use. The buildings EPC is class A with thermal loss 3,9 kW.
