Dvořák, Petr ; Blasinski, Petr (referee) ; Rubinová, Olga (advisor)
The aim of my thesis is to design the project documentation of an energy-efficient house for doctors and nurses, located near the hospital in Kroměříž. The work is divided into three parts. The first part focuses on the architectural and construction design of the building. The second part deals with the design of the technical equipment of the building and its layout. The third part deals with the design and comparison of different cooling sources. The building is a two-storey building with a flat, vegetated roof and its design is in the building permit stage. On the ground floor there is a bistro, a dining room with food preparation, technical rooms and 3 apartments. On the second floor there are 9 apartments and a lounge. In the middle of the building there is a circulation area with a staircase, a glass elevator and a large skylight that illuminates the whole area. Heating is provided by a gas condensing boiler. Ventilation is provided by three air handling units. A hybrid cooling system with heat recuperation from the refrigerant is designed. For partial electricity demand, 62 photovoltaic panels are installed on the roof of the building. The third part deals with the design of alternative cooling solutions for the building. Multi split, VRV and water cooling system with roof top chiller are proposed in addition to the already designed hybrid system. These four alternatives are compared with each other and the most suitable option is then designed.

Energy efficient building of kindergarten in Holubice
Čtvrtečka, Václav ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
The aim of the master project is to design a kindergarten in Holubice, Czechia. The building has three parts. First includes classrooms and auxiliary premises (locker rooms, washrooms, etc.), second technical and staff facilities and the third one includes a gym with equipment storage. The first two parts are designed using load-bearing masonry, reinforced concrete floor slab and flat roof. Gym has a load-bearing system combining masonry and structural frame covered by a semi-circular flat roof. The whole building is equipped with HVAC systems. Heating energy is supplied by two condensing gas boilers. Air quality will be maintained by an air conditioning system. Photovoltaic panels are placed on the roof to support electricity. Rainwater will be collected in accumulation tanks and further used for flushing on the toilets and garden irrigation. The project was developed using AutoCAD (drawings) and Revit. The secondary task of the work is an extensive measurement of the CO2 concentration in a room with forced ventilation. The aim is to combine automatic regulation of forced ventilation, depending on the concentration of CO2. The result of such regulation is higher air comfort, service life of individual HVAC members and saving electricity.
