Rohatec Special Regime Home
Čadová, Veronika ; Vostrejž, Dušan (referee) ; Boleslavská, Yvona (advisor)
The subject of the master’s thesis was to design an architectural study of a new building for a home with a special regime in Rohatec. This request was made in response to the tornado-destroyed building of the S-center in Hodonín. The request required the design of a multi-functional facility with a private garden for 90 patients and 100 staff working over two shifts. The selected land is located at the end of Rohatec, mostly surrounded by forest and a few family houses. At the same time, it‘s located by the main road, so it‘s easily accessible by everyone. The building is designed as a 3 story building with a flat roof and underground parking in the shape of an open U. The shape of the building itself is a compromise between the shape of the land, layout requirements for this type of facility, capacity requirements, and height restrictions according to the master plan. The shape allows for the creation of a private residential garden for the residents of the home, which is closed from the road, with a possible gate connection to the future forest park. The passage between the garden and the building will be enabled by a terrace around the entire perimeter of the inner side of the building. The individual home wings also enable layout separation of the individual departments needed for smooth building operations. Dispositionally, the home has a pharmacy open to the public, an underground parking lot, inpatient and administrative departments, a kitchen with a dining room, a cafe with a buffet, a library, a chapel, a part designated for therapy and space for mani-pedi with a hairdresser, rehabilitation with a gym, and more. The necessary technical background for the operation of the building, workshop spaces, a laundry room with a dryer, an ironing room, and storage rooms are also designed here.

Optimization of combined heat pump and solar PV system for family house
Bojanovský, Jan ; Hudák, Igor (referee) ; Skryja, Pavel (advisor)
The aim of this work is to propose the optimization of a family house system heated by a heat pump in combination with a small photovoltaic power plant and a battery. The research part of the work describes the principle of operation and types of heat pumps, photovoltaic power plants and energy storage from the perspective of their use in a family house. The practical part of the work further focuses on the evaluation and optimization of the system that was newly installed in the family house. Because in this particular case the system was recently put into operation and it was not possible to obtain data continuously for the entire year of use, the missing data were supplemented by simulation or approximation. Based on a combination of measured and simulated data, the system was subsequently optimized for the most economically efficient use of electrical and thermal energy. Based on the outputs of this work, it is possible to assess the economics of operating the heat pump and photovoltaic power plant and the suitability of installing this system in an older family house.
