The diploma thesis is divided into three parts. The first part is theoretical devoted to the introduction of BETONG building material. And next It is also devoted to themes of low - energy buildings and nearly zero-energy buildings, heat sharing and thermal comfort. In the second part is the concept of the heating system elaborated in three variants of the design in the scope of the study for the new family house. The third part is devoted to use of shell blocks of the BETONG with internal contact insulation compared to other masonry systems.

The aim of this project is heating and warm water preparation for apartment block in Choceň (Pardubice region). Apartment block has three aboveground heated floors and one underground unheated floor. The heat source is gasifying firewood boiler or pellet boiler which is at the same time used for water heating but only in the winter time. The other parts of the year the solar collectors are installed and used for water heating. The heat source is located in detached room with its own access, in boiler room.

This thesis deals with the design of the heating system in a Polyfunctional building. The design is solving heating of a Polyfunctional Object in Kostelec nad Ohří. The building has basement and two floors. The building is heated by means of panel, tubular and floor convector heaters. The source of the heat is located in the boiler room in the basement.

The goal of this thesis is to process three variants of energy performance certificate of the building with different heat sources. The building is in mountain area Bílá in Frýdek-Místek region. The thesis has three parts. First part is focused on literary research of heat pumps. Second, calculation part, describes three proposed heat source solution. First heat source is heat pump, second is pellet boiler and the last one is gas condensing boiler. All three variants are evaluated from the economic and ecological perspective. Last part of the thesis contains three energy performance certificates of the examined building.

Diplomová práce je rozdělena na tří částí. První částí je analýza tématu, cílů a způsobů řešení, která obsahuje i teoretickou část. Druhá část je aplikace tématu na řešeném objektu včetně podrobného výpočtu a návrhu otopné soustavy, přípravy teplé vody, dvou variant alternativních zdrojů tepla a jejich porovnání, které vede k výběru lepšího zdroje tepla. Třetí část je projekt a obsahuje technickou zprávu vybrané varianty a projektovou dokumentaci, která obsahuje všechny potřebné výkresy.

The aim of this master thesis is to design a low-energy building for civic amenities, specifically the design of a recreational wellness centre. The building has an L-shaped floor plan with a flat roof and is designed with two above ground and one underground floor. The ground floor will serve as a wellness centre with a swimming pool and saunas. Massages and solariums are proposed on the 2nd floor. Technical facilities are located in the basement. The first part of the thesis is devoted to the architectural and structural design. Structurally, the building is divided into two parts. The part of the administrative facilities and the massage rooms consists of a construction of the character of a transverse wall system made of cut brick blocks and insulated with ETICS. The internal masonry is designed in ceramic ground bricks. Ceiling structures are in the form of continuous reinforced concrete slab. The building is based on footings and waist foundations. The roof of the building is single-skin flat with a gravel. The wellness part is made up of a monolithic diaphragm skeleton with high slenderness columns. The horizontal load-bearing structure in this case again consists of a continuous monolithic reinforced concrete slab. The second part of the thesis deals mainly with the environmental engineering of the buildings. The building will be heated by a pellet boiler and will also use energy from photovoltaic panels. Ventilation in the building is provided by air handling units with heat recovery. The third part of the thesis deals with the assessment of solar gains in the indoor environment of the pool hall. Three variants are proposed with multi-criteria evaluation and the optimal option is selected. The thesis is mainly elaborated in Archicad, Deksoft, MS Excel and Word software.
