The project consists of the modernisation of 52 heating systems involving the replacement of carbon-intensive heat sources (49 tile furnaces and 3 coal boilers) as part of the eligible costs. These sources will remain in 19 premises (ul. Kraszowicka 32, 34, 35) exchanged for modern gas boilers with an energy management system (no connection to the district heating network); other 33 units (ul. Theatre 25, st. Passers-by 3, 4, 5, 6, 8, 10) will be connected to the district heating network. In total, the project will cover 10 multi-family buildings in the central part of the city of Świdnica. Replacing 19 high-emission heat sources with modern gas boilers will lead to a reduction in CO2 emissions above 30 % on a given boiler (minimum 31 % reduction; reduction max 64 %). Connecting the remaining 33 dwellings to the district heating network together with the replacement of 19 boilers will lead to a 100 % reduction in PM10-1.07 tonnes per year and PM2.5-0.91 tonnes per year. The main objective of the project is to increase energy efficiency in the residential sector in the City of Świdnica by modernising heating systems in 52 residential units in order to combat chimney emissions in the ITI AW area by reducing CO2 and particulate matter emissions PM10 and PM2.5. All premises have simplified audits – attached together with the auditor’s recommendation to this application. The applicant and Investor is the Municipality of Świdnica. The Project Implementation Unit [JRP], composed of qualified employees of the Applicant, was set up to implement the project. Based on the previous experience of the Applicant, this guarantees the correct implementation of the project and the achievement of the indicators set. As part of the project, the municipality of Świdnica will take measures to raise the environmental awareness of the local community by launching a dedicated website and a number of online publications available for download (free of charge).
