Energy modernisation of Kapuvár Térségi Primary School

A modern drainage solution was needed around the locally listed building. The previously existing plaster had to be removed from the masonry as soon as possible, and in the damaged areas the plaster had to be completely removed up to the brick surface, and even the joints had to be scraped out. The existing facade was then rendered with thermal insulation plaster after the partial removal of the plaster. At the same time, rock wool insulation was laid on the end slab. Achieving a higher energy class required the installation of completely new wooden windows. The entrance doors of the building complex that were not replaced had to be repaired and repainted partly on site and partly (wings) by transporting them to a workshop. To heat the building, a new 2. one VIESSMANN VITODENS 200 W natural gas fired heating boiler with a capacity of 80 kW was installed in the boiler room on the first floor. Last but not least, a solar panel system was installed, with a DC side fork power of 30kVA.
