Slovakia – Secondary school construction work – Zníženie energetickej náročnosti SOŠ technickej Dubnica nad Váhom

The subject of the contract addresses the building renovations of individual pavilions of the school area with the aim of reducing energy demand and operation from the perspective of energy savings of individual buildings. It is mainly about a comprehensive design of the thermal insulation of the perimeter walls of the buildings, insulation of roof structures, and a comprehensive replacement of the infill of openings in the perimeter walls – windows and doors of individual pavilions. The current school area, which consists of several pavilions – blocks, was built at the beginning of the 1960s. The prevailing part of the buildings is built in the form of masonry structures made of solid fired bricks or CDm bricks. Such a solution of the perimeter structure from the point of view of energy requirements no longer meets the requirements and therefore it is necessary to improve the technical parameters of the masonry with additional thermal insulation. The insulation of the walls of individual objects is designed in the form of a contact insulation system with a final surface treatment with plaster and adhered ceramic cladding imitating the appearance of solid brick masonry. For the needs of thermal insulation, the primary material chosen is mineral wool and the supplementary material for insulating structures below ground level is extruded polystyrene. The replacement of the infill of openings is focused on the replacement of the original double wooden windows with new windows and doors made of aluminium and plastic profiles with triple glazing. The implementation of repairs and insulation of the facades of individual objects will not result in a change of the function of use of the building, changes in the spatial character of the building or a change in the built-up area. Similarly, the ratios of the areas for collecting rainwater from the roofs, which are drained into the rainwater drainage system, will not change.
