The project concerns the thermal modernisation of the building of the School Complex in Bytom Odrzański, i.e. a public utility building in the Commune of Bytom Odrzański, ul. Church 9, 67-115. The facility is planned to: insulation of vertical and horizontal partitions, replacement of window and door joinery, modernization of ventilation for mechanical ventilation with heat recovery, modernization of the heating system, including replacement of the heat source (80 kW air heat pump system and gas boiler as a peak heat source), remote monitoring and management system of heat and electricity energy, replacement of lighting fixtures with LEDs and expansion of the PV installation for supplying heat pumps by 10 kW (up to 37 kW). Tasks in the project: 1 Comprehensive thermal modernization of the building 1.1 Thermal modernization of the building - works resulting from the energy audit 1.2 Thermal modernization of the building - works resulting from the implementation of the objectives of EZŁ 2 Information and promotion activities 3 Preparatory work 3.1 Preparation of the energy audit 3.2 Technical documentation 3.3 Natural inventory 3.4 Preparation of the application application and annexes 4. The building of the School Complex in Bytom Odrzański was built in the shape of two rectangles connected by a connector. As part of the task, the following work is foreseen: Warming of external walls, external in the ground (insulation: 15cm, 20cm) Warming of the roof (insulation: 30 cm) Replacement of windows and doors for joinery with heat transfer coefficient U = 0,900 W/(m2∙K) Replacement of gravity ventilation for modern systems meeting energy efficiency requirements. Expansion of the PV installation for heat pumps by 10 kW (up to 37 kW) Modernization of heat sources - Disassembly of the old heat node and installation of a new one - Installation of an air-water heat pump: Installation of a system for regulating the heat supply and controlling the central heating system Modernization of the interior and exterior lighting of the school building The main objective of the project is to: Improving energy efficiency in the public buildings sector in the Bytom Odrzański Commune by optimising energy management in the Primary School building in Bytom Odrzański.
