Description
The project concerns comprehensive thermomodernisation of the building of the Public Elementary School No. 2 in Olesno. The leading body of the school is Olesno Commune, the school has an average of 410 pupils in grades 1-8. It is a free-standing building, built in prefabricated technology in 1996. The building consists of 5 segments: A, B, C, D, E. Blocks A, D and E 3-storey, with basements - heated cellars. Blocks B and C 3-storey, no basement. Total area of the building is 9482 m2, volume 45300 m3. External walls prefabricated according to the Żerań system, insulated with 4 cm thick wool, steel structure roof, covered with tar paper, wooden/PVC windows, steel/wooden/aluminium external doors. The building is heated by two gas-fuelled boilers. Pumped water central heating system, insulated within the boiler room and ductwork. Installation not thermally insulated in heated rooms. Steel plate and tube radiators fitted with radiator valves, 50% with thermostatic heads removed. Fluorescent, incandescent and LED lighting fixtures are installed in the building, metal halide fixtures in the gymnasium - all in poor condition. Within the framework of the designed deep thermomodernisation, it is planned to insulate the ceiling, roof, ceiling over the entrance, walls in the ground, external walls, replacement of windows and doors, modernisation of the heating system and the hot water installation, including the installation of a heat pump and a gas boiler, execution of mechanical supply and exhaust ventilation. A PV panel system is envisaged to produce electricity for the building''s own energy purposes. A PV panel system with a total capacity of 49.68 kWp is planned. Replacement of lighting fixtures with new ones based on LED sources, installation of motion sensors and installation of a building energy management system (EMS) are planned. The effects of the project will be reinforced by an educational campaign on the environmental impact of the project.
