Amorphous silicon photovoltaic windows intend to not only improve thethermal bridge that windows represent but also to collect energy from theradiation incident on the windows themselves. This kind of windows can beapplied anywhere, however to maximize the benefit these can bring it isrecommended for sun-oriented façades. This research aims to investigate theimpacts that this type of windows can have on the energy performance andthermal comfort of a three-story historical stone building in the cold climateof Sweden using the simulation software IDA ICE. The model used for thesimulations had previously been developed and tested in other researches thatinvolved this same building. This research shows that the yearly energyconsumption for the townhall can be reduced down to 280000 kWh,representing a reduction of 5000 kWh compared to the base model, if theHigh transparency windows are applied, representing a reduction of 1,7%.The use of any of the four proposed windows has shown to increase thepercentage of best comfort hours by at least 5% and lowers the percentage ofunacceptable comfort hours at least by a 10%, even having cases with 0 hoursat this comfort level. The upper level of the South façade would be able toprovide the building with 800 kWh yearly, being the level with the highestenergy collection due to having more windows. Approximately every windowcould collect around 90 kWh yearly, which represents 20% of what a solarpanel of the same area correctly oriented could obtain in the same period oftime. Thus, the amorphous silicon photovoltaic windows do not seem to bethe best change despite offering a very promising thermal comfort. Theeconomical viability of this project is what prevents it from being feasiblesince the energy saving/obtaining characteristics are not of great magnitude.

The subject of the diploma project is the design of new townhall building of district Brno – The north. The townhall is designed at the place of existing barracks and the urbanistic plan of whole area was the previous school work. The townhall as a new centre of the district is dominant in its location, the main motive is openness and permeability. The volume is created from two basic cubes with offices which define public space between with indoor public square and specific volumes of halls in dynamic composition. Communication structure is formed by footbridges and staircaises connecting all volumes. The building combines reinforced concrete and steel structure and is covered by glass shell around.

Chosen territory is located on the Libušina street, Brno - Kohoutovice. Socio-kultural center with townhall will serve as the dominant of district. Due to its shape, which is growing up, it reflects the character of the surrounding high-rise buildings. Entrance to the building is concentrated in one space, the communication part, which connects two masses - the town hall and socio-cultural center. Office space is structured around the perimeter of the building and also organized as a contact point with the society, due to glass partitions. The interior space of the town hall is lighted by glass atrium that allows sunlight penetrates to the whole building. Socio-kultural center with townhall is an expressive architectural element and includes three functions: culture, recreation and sport. The main part of the building is the multifunctional hall, that is used for such purposes as big celebrations, performances, music and dance events and film screenings. The idea to create the function of sport is based on interview and wishes of the local inhabitants. The restaurant, library and a recreation space have large glass windows, which allows visual connection between the interior and exterior and creates a pleasant aesthetic impression.

Abstract The area, for the socio-cultural center with townhall, is located in the Brno-Kohoutovice district next to the Libušína třida bus stop. It is surrounded by apartment blocks, shops and services. Libušína třida provides easy access to the transport systém. The piece of land is located to the forest. The building comprises three main spaces ( the townhall, a multi-purpose hall, socio-cultural center), which are all interconnected and are directly and easily accessible to a car park. There is a public space in a form of an open square, which generates a pleasant atmosphere for leisure breaks and social activities. The aim is to protect a green image of a district and create an environmentally friendly building.
