The subject of this diploma thesis is to design a NZEB hyporehabilitation building in the hospital campus in Havlíčkův Brod. The building has three above-ground and one underground floors, connected with a staircase and elevator. It contains five therapy rooms with an access to a terrace and stables for up to seven horses. The underground floor includes a corridor, a technical room, an air conditioning unit room and warehouses. On the other floors, there are facilities for hipporehabilitation staff facilities and stables for horses. The building is based on reinforced concrete foundations. The vertical load-bearing structures are designed from ceramic blocks. In the basement, the cast-in-place reinforced concrete cladding is insulated with ETICS. The floor structure consists of prefabricated reinforced concrete panels. The staircase is designed as a reinforced concrete prefabricate. The building is covered with a flat, single-skin roof, partially designed as green roof. The heating and domestic hot water are privided by the connection to the campus central heat supply system using a heat-exchanger. Ventilation in the building is provided by air-conditioning units with heat recovery. Photovoltaic panels are installed on the roof of the building. In the third part, the details in the 2D temperature field of selected parts of the building were assessed, modifications were proposed and an evaluation was carried out.

Energy retrofitting of a family home to the nearly zero energy building
Uhlíř, David ; Fišer, Jan (referee) ; Charvát, Pavel (advisor)
The diploma thesis is devoted to reducing the energy intensity of a two-storey family house from the 1960s, to a building with almost zero energy consumption. First, the family house is analyzed in terms of the condition before reconstruction. The result of this analysis is a certificate of energy performance of the building in its original condition. Within the individual chapters, I subsequently propose specific energy saving measures. At the end of each chapter, these measures are economically evaluated using the New Green Savings Grant Program. The first measure is dedicated to improving the thermal technical properties of the building envelope. This is ensured by the complex insulation of the family house and the replacement of the original windows and doors. The second measure is devoted to the design of a suitable method of forced ventilation with heat recovery. As part of the third measure, I assess and select a suitable heat source that will replace the original heat source of the family house. As a final measure, I propose the use of a renewable energy source in the form of a photovoltaic system, which is based on energy simulation in the program DEKSOFT FVE. At the end of my work, I am developing a building energy performance certificate, which assesses the fulfillment of the condition of a building with almost zero energy consumption.
