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.

Mrnuštík, Petr ; Vrána, Jakub (referee) ; Počinková, Marcela (advisor)
The bachelor’s thesis focuses on designing a low-energy detached house in village Jablunka. Thesis is divided into two parts, first one is aimed at structural and architectural design, whilst the second one focuses on building services, especially heating with solid fuels. The house is divided into a two-storey and a single-storey part. Ground floor includes master bedroom, utility room and mainly open-plan living room connected to kitchen which opens onto a deck and garden. First floor then includes two bedrooms and study. Both floors have their own bathrooms with separate toilets. Structural system is designed as masonry walls from aerated concrete blocks, which are transferring load onto plain concrete foundation strips. Floor slab is to be made of reinforced concrete. Two-storey part is covered by prefabricated rib–and–filler gable roof with 15° slope, from aerated concrete fillers and reinforced concrete, the one-storey part has flat roof. Walls are insulated by 140 mm of mineral wool, plinth then by 120 mm of XPS. Ground slab will be insulated by 220 mm of graphite EPS, floor slab is insulated by 40 mm of impact sound insulation from mineral wool and 50 mm of EPS with installation layer. Flat roof is insulated by 220–340 mm of mineral wool with screed to fall function. Gable roof is then insulated by 180 mm PIR panels. Rainwater will be collected and stored in rainwater tank for gardening use, overflow will then lead to drainage blocks, where the water can be absorbed into soil, with overflow into stormwater sewer system. Ventilation is designed equal pressure, mechanical with enthalpy heat recovery exchanger and heating battery covering ventilation losses. Main heating source is solid fuel boiler, storing its energy in 750liter hot water tank, from which is the heat distributed into 200liter domestic hot water tank, ventilation heating battery and heating elements such as convectors, panel and rail radiators.

Gel infusion screen system for additional waterproofing of various types of masonry with share of secondary raw materials
Melichar, Jindřich ; Klečka,, Tomáš (referee) ; Dohnálek,, Pavel (referee) ; Novotný, Miloslav (referee) ; Drochytka, Rostislav (advisor)
Virtually any construction project in our climate zone is facing some form of moisture. Older and historical buildings are mostly affected by the negative impact of water. Previously, the additional reduction of the moisture was executed only by mechanical methods, pushing insulating sheets or breaking through and cutting of masonry. Over time chemical methods were also invented, which are compared to the mechanical considerably simpler and user friendly applications to statics of treated buildings, making them ideal for the treatment of historical buildings or buildings that would not bear significant disruption. The main principle of chemical methods of redevelopment of wet masonry is the application of special material into the line of drilled holes with a given pitch. Subsequent penetration of the grouting material is believed to intersect an arc of individual drill holes, and thus to create so-called grout curtain that prevents the accumulation of water above it. Injection material may also contain a proportion of secondary raw materials, thereby reducing the influence of the impact of production on the environment. Efficiency infusion materials in masonry affected by many factors, such as temperature, humidity, or the type of material treated. It is also an important factor to determine the effectiveness of the remediation of the material, proving its ability to penetrate the building material by identifying its presence in it.
