The main assignment of this diploma work was reconstruciton of a school buildings complex. The main aim was to achieve a passive standard of buildings and to get rid of its technical shabbiness. This complex is located in the village Vígľaš as a part of a residential area. The school was built in 1970 for children from all surrounding settlements. It consists of 6 detached buildings. Nowadays some of them are not being used and the problem is that children have to pass the exterior to get to the other building. That's the reason why it was necessary to improve the passage between them and to develop functional and operational links in dispositions. This thesis proposes to connect the two main buildings with two corridors that will ensure comfortable passage between these buildings. One of them would be a long ramp, which is also suitable for disabled people. Between these buildings it was also necessary to build a new part with a canteen. This space was created by the construction of a new building with a sloping ceiling as a conclusion of the ceiling over the ramp. The shape of the new part of the building lines with the shape of the communication ramp and results in two sloping masses, which intersect only in the view but not in the mass. My design tries to comunicate with the surroundings of the building, which must be visible on construction and its material solution. The connection with surroundings is provided by large green roofs that is accessible for people. This proposed reconstruction would help to achieve a passive standard of the complex and therefore radically increase its energetical efficiency.
