The theoretical part of the thesis deals with the hydraulics of heating systems. The aim of the project is a design of the heating and hot water preparation system for an apartment building. The building has 6 above-ground floors and 2 underground floors. Two different options of heating systems were designed, comparison and results are presented in the thesis. In the first case the heat source during the winter season and for water heating, where chosen two gas condensing boilers, situated in separated room on the second underground floor. In the second case, each apartment has its own gas condensing boiler. The experimental part of the project deals with measurements of pressure losses in water armatures used in heating systems. The aim of this part is the determination of coefficients of added resistance for uncontrolled elements, which are normally presented as tabular value. In thesis are presented results for a ball valve, backflow preventer, filter, for slide valve and thermostatic valve. Measurements for thermostatic valve where done with different settings and results are compared with parameters listed in the datasheet.

The subject of my diploma thesis is the design documentation for the pension which is designed for the elderly and will be supplemented with a specialty from the air-conditioning branch. The building is situated in the western part of the town Bystřice nad Pernštejnem and it's located at 3058/3 about the total area of 8315,2m. The total footprint of the suggested building is 1161,2 m. The subject has got an irregularly-shaped floor plan. It is made of three subsequent triangels, it has got three above-ground floors with partial basement. The roof of the building is suggested as a warm flat roof with coating insulation. The structural system of a building is designed as longitudinal with shear walls. The exterior building masonry is suggested from sharpened clay blocks Heluz STI 40 with thickness 400 mm. The contact thermal insulation system ETICS with an insulant from EPS with thickness 100 mm is designed for all building. The building for the elderly is from its bigger part meant for citizens who are older than 65 years in the flats for one or two persons in 2FLR and 3FLR. The space for essential services to the residents is located on the 1st FLR. There are also a cafe and a surgery located in a smaller part of the 1st FLR, which are to be used both by the residents and the public.

Purpose: The aim of this study is to present the economic, environmental impact, and energy saving benefits of replacing an electric boiler to a bedrock heat pump or district heating. Furthermore, the impact of additional insulation will also be presented. Method: The technical, environmental, and economical aspects of the various heat sources in this study are gathered through websites and reports from agencies, industry organisations and corporations. A case study on a family house built in 1971, heated with a combination of electric boiler and air-to-air heat pump has been made. The study investigates the impact of replacing the existing heat sources with newer and better alternatives along with additional insulation. Results: The results present the energy demand for active heating, economic analysis, environmental impact, and the impact of additional insulation. Moreover, a comparison between the heat sources and the additional insulation is presented to show the difference between them. The case study objects demand for active heating includes passive heating, heat losses through the building envelope, heat losses due to ventilation. With all these factors combined, the family house has an annual active heating demand of 11 700 kWh. The energy consumption of the electric boiler combined with air-to-air heat pump (COP 4) have an annual consumption of 7 500 kWh. The required energy from the district heating goes up to 11 700 kWh and the bedrock heat pump (COP 3) have the lowest energy consumption of 3 900 kWh. However, the amount of electricity needed is 400 kWh for district heating compared to the other alternatives that require 7 500 kWh and 3 900 kWh. For the economic aspects, the installation and operating costs for the electric boiler combined with the air-to-air heat pump, district heating and the bedrock heat pump are concluded. This shows that, on one hand the bedrock heat pump is the most expensive heat source to install but on the other hand, the cheapest to operate. Furthermore, this study compares the emissions of carbon dioxide equivalents from the production of district heating and electric energy. Due to the clean electric energy in Sweden, district heating has the highest negative impact on the greenhouse effect as it uses energy resources that have high emission of carbon dioxide equivalents. The environmental impact of the electric boiler, air-to-air heat pump and the bedrock heat pump vary depending on the energy source used to generate electricity and can in the worst case be higher than for district heating. New values with the additional insulation suggest that the improved building envelope will have a positive impact on the operation costs, energy saving and emissions. As an example, the demand for active heating can be reduced with up to 30%. Conclusions: The conclusion is that the comparison of heat sources contains many uncertain variables. Consequently, the result of this study does most likely not apply directly to other study objects. The results may vary if, for example, the geographical location or electricity agreement is changed.

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.
