The subject of the project is the deep thermomodernisation of 4 educational establishments (Preschool No. 7, Primary School No. 9, Educational Institution Complex No. 2, Public School No. 4), City Hall. The facilities are located in the town of Skarżysko-Kamienna and perform important social functions in OSI. The project falls within the specific objective of measure 3.3, investment priority 4c of the 2014-2020 ROP WW, i.e. increased energy efficiency of public buildings and the housing sector. The implementation of the project has a positive impact on the environment. Reducing energy consumption for buildings will improve air quality. For the project, the optimal project implementation option was selected based on the results of energy audit and energy efficiency audit (UM). It is planned to: insulating exterior walls, floors, replacement of window and door joinery and modernisation of the heating system. The modernisation of the central heating installation provides for: replacement of radiators, installation of thermostatic and vertical valves. Facilities will be equipped with energy management system, including heat counts, weather temperature sensors. The UM provides for the replacement of lighting and installation of photovoltaic panels. In two facilities, the furnaces will be replaced with gas and fittings. Implementation of the project from Q2 2018 to Q4 2022 As a result of the project, the estimated annual reduction in greenhouse gas emissions is 462.507 tonnes of CO2 equivalent. Number of energy-modified buildings 5 units, usable area of buildings subject to thermal modernisation 8471.74 m². All mandatory key result indicators are included in the project: amount of thermal energy saved 4908.59 GJ/year; electricity 31,866 MWh/year reduction of final energy consumption 5137,51 GJ/year,primary 1693334,33 kWh/year. In addition, all horizontal output and result indicators are included in the project.
