Optimization of the cockpit ventilation system of a small transport aircraft
Vícena, Ondřej ; Charvát, Pavel (referee) ; Fišer, Jan (advisor)
This thesis deals with the optimization of the cockpit ventilation system of a small transport aircraft. The current system does not allow the ECS system to function without activating the main engines, which limits its effectiveness in ground operations. The theoretical part provides a basic theoretical framework for understanding and evaluating the thermal comfort in the cockpit, including heat transfer modes, cabin microclimate during different operating modes, and the definition of fundamental concepts related to ECS in pressurized and non-pressurized cabins. The experimental part focuses on the extension of the system with a suitable electric motor fan to provide cabin air supply even during ground operations at the airport. It includes testing the thermal effect of the supplied untreated air on the human body using a thermal manikin and a cabin simulator. In addition, heat removal from the body surface and subjective thermal sensation at different airflows and outlet routing were investigated for ambient temperature.

Community housing in Brno-Komín
Streďanská, Lucie ; Pekár, Pavel (referee) ; Novák, Antonín (advisor)
The subject of the master's thesis is the development of a proposal for a multi-functional building as a part of a new community housing complex in Brno-Komín near Řezáčova Street. The proposed area is situated between the existing panel houses of the original housing estate and open countryside in a relatively sloping terrain. The current condition of the site is neglected. There is a large amount of air raid greenery, and the entire area is impermeable. The goal of the proposal is not only to make the area accessible across the board, but also to design a varied residential environment for new and existing residents. This primarily involves differentiating individual spaces and proposing a wider range of activities in contrast to the original 'monofunctionality' of the existing housing estate. The design of a specific house in this diploma thesis follows the urban design concept, transportation design, greenery, rainwater management, and microclimate solutions outlined in the urban study from the previous semester.

Detached house, Kreslice
Procházka, Nikola Leilani ; Jelínek, Petr (referee) ; Kolář, Radim (advisor)
The aim of the bachelor’s project is to design a single-family home in nZEB standard. This project has two parts. Part one presents the project documentation. Designed building is located in Křeslice. The building is a two-storey detached house with a rectangular footprint and an extensive green flat roof. The main entrance faces the north while most windows face the south. The ground floor consists of living room, kitchen, storage room, utility room and restroom. In the upper floor there are two kid’s rooms, master bedroom, study, and bathroom. The building is founded on concrete strip foundations. The vertical loadbearing structures are masonry consisting of clay blocks. The internal partition walls are from acoustic masonry. The ground slab as well as the floor slab consists of in-situ concrete. The building is insulated using contact insulation system of grey EPS. Part two proposes the design of building services. The project provides designs of plumbing, heating, and ventilation. Focus is on the ventilation system design. Mechanical ventilation unit with heat recovery is installed. Air is distributed by ducts in suspended ceiling and round diffusers. The building is equipped with air – water heat pump, which provides heat for floor heating and domestic hot water. Rainwater from roof is collected and stored in underground tank and later used to water the garden. Safety overflow brings any excessive rainwater to the infiltration tanks on the plot. The building is connected to water supply, sewage system and electrical grid. Building’s Energy Performance certificate is included.

Community centre ventilation
Pokutová, Karolína ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The bachelor thesis focuses on the design of HVAC (Heating, Ventilation, Air Conditioning) systems for a community center. The goal was to create a suitable indoor microclimate for the building by using ventilation unit. The work is divided into three parts. Part one is theoretical section. This part deal with the components of ventilation and air conditioning systems, terminal units and noise in HVAC systems. The second part is calculation section and focuses on thermal balances calculations, airflow calculations, distribution elements, duct sizing, design of ventilation units, noise attenuation calculations and insulation design. The third part comprises the detailed project documention.

Single-family house in Troskotovice
Slunečková, Eliška ; Pilný, Ondřej (referee) ; Kalousek, Lubor (advisor)
This bachelor’s thesis aims to design a single-family passive house. Designed house is situated in Troskotovice on a flat building plot. The house is composed of two volumes: a bigger two-floor part with a gable roof and a smaller one-floor part with a mono-pitched green roof. The house is divided into a work zone in the north and east of the ground floor, a social zone in the south of the ground floor and a private zone placed on the first floor. The structural system of the building is a wood frame with timber truss and joist floors. A cast-in-place reinforced concrete slab is used for the foundation. The first part of the thesis includes architectural, structural, and material designs with assigned calculations such as acoustics, daylighting, energy certificate and fire safety calculations. The second part of my bachelor´s thesis consists of heat, ventilation, and plumbing designs with a focus on the ventilation design. An air/water heat pump is used for heating up domestic hot water and water for a wall heating system. The house is equipped with heat recovery ventilation system. Rainwater from roofs is collected in an accumulation retention tank and used for watering a garden and toilet. Excessive rainwater s infiltrated in an infiltration basin on the plot. Design of the house includes connection to the electrical grid, optical grid, water supply and sewage systems.

Storage area with administrative building
Šesták, Tomáš ; Dohnal, Jakub (referee) ; Pěnčík, Jan (advisor)
This master thesis focused on the design and elaboration of project documentation for the purpose of a storage area with an administrative building, consisting of the premises SO 01 - storage hall and SO 02 - administrative building. Objects are located on parcels no. 4006/16, 4006/17, 4006/18, 4006/19, 4006/23, 4006/24, 4006/26, 4006/27, 4006/28, 4006/29, 4006/30, 4006/31, 4006/32, in the cadastre unit Dolní Bojanovice. They are located on an investor's land. Traffic connection is provided by the exit from the car park on the local road. All engineering infrastructure engineering networks are located near the site. The design of the building respects the local zoning plan. Project documentation is prepared in accordance with the current wording of applicable laws, decrees and standards. The project solves the structure functionally divided into objects SO 01 and SO 02, which are both operationally and structurally connected. The construction of objects is statically independent. The object SO 01 is designed for the storage of building material intended for storage in dry rooms. In addition to the storage space there is the air-conditioning machine room. The SO 02 facility serves administrative and staffing facilities. In the basement of the building there are rooms of technical background and archives. The SO 01 is designed as a full-metal mounted object with a counter roof and foundation pads. The design system of the SO 01 object is columnar with steel columns. The SO 02 building is designed from a wall construction system made of aerated concrete blocks with reinforced concrete ceilings, base strips and a flat roof. The SO 01 has a 65.5x20.2 m ground plan. The perimeter shell of the building consists of assembled sandwich panels with a core of pure material. The largest ground plan dimensions of the so 02 are 26.75x10.35 m. The perimeter shell is made up of 375 mm piece concrete blocks with a 150 mm contact system.
