The goal of my Master’s thesis was to design a building for public services. I chose to design a sports hall in town Strážnice. The building had 2 floors with a playing area higher, than the floors combined. The first floor was divided into 4 areas – playing area, athletes locker rooms, technical facilities and facilities for spectators. Second floor had clubroom for athletes and buffet. Loadbearing structure of the building is from precast reinforced concrete frame with ceramic block infill walls and cast-in-place reinforced concrete slabs for floors and flat roofs. The roof over playing area was sloped from glue laminated timber girders, while the rest of the roof is flat. Walls were insulated with mineral wool, Flat roofs and floor with expanded polystyrene and sloped roof with PIR. The foundations were cast-in-place reinforced concrete pads, with strips under staircases. Doors and windows had plastic frames. Windows were triple-glazed. Partition walls were designed to be from plasterboard.
Heating and cooling were designed to be done with hot/cold air through 2 MVHR units. First had air exchange 11000 m3/h, second had 3975 m3/h. First unit was connected to 4 heat pumps with total heating output 68 kW. Second unit was connected to 3 heat pumps with total heating output 39 kW. Energy for cooling was gained through the same heat pumps. Hot water was gained through hot water cylinder with inbuild electric insert and volume 1516 l, that is connected to 3 heat pumps with total output 51 kW. The internal sewage system will be connected to the city sewer, while rainwater will be collected, used for watering garden, or infiltrated into the soil.  On roof 150 photovoltaic panels were installed with total output 102 kW.
The specialized part of the Master’s thesis describes calculations of linear thermal transmittance of several assembly details and further calculation of correction for thermal bridges used for average heat transfer coefficient of a building. That was then compared to correction used in standardized calculations. First, simplified elements of assembly details using AutoCAD software were created. Those were uploaded to DEKSOFT Tepelná technika 2D software, where materials to fill in the elements and boundary conditions were selected and linear thermal transmittances were calculated. Two different corrections for thermal bridges were subsequently calculated. Only positive linear thermal transmittances were counted in the first correction, while both positive and negative transmittances were counted in the second one. They were ΔU1=0,0046 W/(K.m2) and ΔU2=0,0003 W/(K.m2), which were way better than the standardized ΔU=0,02 W/(K.m2). The first correction for thermal bridges, as it is used in standardized calculations, was used while calculating average heat transfer coefficient that was U=0,1241+0,0046=0,129 W/(K.m2), which classified the building in building envelope thermal efficiency class A, while the second correction was calculated to find out the difference between standardized and non-standardized calculations. The difference in corrections was 0,0043 W/(K.m2).
