The project is owned by the Municipality of Salgótarján, 3100 Salgótarján, Arany János út 19/A, hrsz: Located in property number 3735, it is intended to renovate the building of the Central Nursery in Mackóvár for energy purposes. The Central Nursery School of Mackóvár is located in the downtown of Salgótarján. The building designed by the Hungarian Géza Ybl Prize-winning designer was handed over in 1976. With 13 kindergarten teachers and 6 nurses, the kindergarten life started in 6 groups with 150 children. Currently, the Central Kindergarten has 420 places with 226 young children. The condition of the building has already deteriorated and its maintenance costs significant, therefore the Municipality is planning to renovate the entire building in the TOP-6.5.1-16 project. In parallel, the Municipality plans to create a mini crèche separately in the building, thanks to a winning TOP-6.2.1-15 project, in which a mini crèche with 16 places will be set up. The energy renovation also affects the mini crèche, in which the doors and windows of the mini crèche will be installed and the part of the building is insulated. Energy development thus includes: — Thermal insulation of the wall and floor structures of the existing building. — Replacement of external doors and windows. — Installation of solar system. — Luminaire replacement for modern LED design. Self-eligible activities envisaged in the project: — Energy efficiency-oriented development of municipal-owned buildings by upgrading their external boundaries: As thermal insulation of the flat top of the building, extruded polystyrene foam thermal insulation is made in a reverse layered roof structure. The thermal insulation boards will be equipped with a staircase with side training. Extruded polystyrene foam thermal insulation is made as bark forming. Existing wall structures will be equipped with 16 cm Baumit Star facade insulation system. The applied multilayer insulating plaster system will consist of dispersion reinforced cement bonded, premixed adhesive mortar, thermal insulating mineral wool boards and surface strengthening glass fabric, coloring plaster. The thermal insulation of the building will be extruded polystyrene foam. — Small power plant with a maximum household size (HMKE) photovoltaic system to meet its own electricity demand: A small solar power plant that feeds into the grid will be built, where the electricity generated from solar energy will be used directly and the surplus will be fed into the electricity supply network. Growatt 30000 TL3-NS or equivalent inverter is installed on the flat roof with 112 Amerisolar 270 W solar batteries (or equivalent). Mandatory non-eligible activities to be carried out on its own: — Accessibility: The building has a barrier-free toilet. The construction and fitting-out of these rooms is designed in accordance with the requirements of the OTÉK. Due to the terrain conditions, the building cannot be approached without barriers, nor can it be constructed, so an elevator is installed in the connection to the landing stop of the stairs. The elevator was made with reinforced concrete construction elevator shaft. The elevator is made with a so-called machine-free design with a 110/140 interior lift cabinet. In addition, doors complying with the accessibility requirements will be installed and accessibility for the blind and visually impaired will also be made in the parts of the building affected by the renovation. Within the building, room boards with pictograms are made for easier orientation and orientation. — Publicity — Developing training material and providing training Optional, ineligible, ineligible activities: — Modernisation of existing outdoor and indoor lighting systems related to the building concerned: Switch to LED bulbs. The replacement of doors and windows reduces consumption by 18 %. The thermal insulation of the facades (min. 16 cm thickness) is 9 %, the thermal insulation of the roofs (min. 20 cm) saves an additional 22 %. In addition, a modern solar system will be installed and the lighting system will be upgraded, including LEDs. All the exterior doors and windows of the building will be replaced in the project in a heat-insulated wood and plastic design of varying sizes and properties. Due to the size of the building and the planned condition, a large number of doors and windows will be constructed (total of 174). Existing sinkholes are used for insulation on roof surfaces. The building is equipped with heating with mixed (natural gas and renewable) district heating system.
