The project aims at increasing the energy efficiency of a municipal building from the cultural infrastructure. A municipal children’s complex is registered as a cultural organisation and is registered in the register of the Ministry of Culture. The municipal children’s complex is an extracurricular unit serving the system of folk education. It is intended to organise activities related to the development of children’s interests, abilities and needs in the field of science, technology, arts, recreation and sport in their leisure time. The measures for energy efficiency in the building of the CSS will be implemented on the basis of an energy efficiency audit accompanied by a valid energy performance certificate of the building and an audit to establish the technical characteristics of the building with a technical passport. At the stage of implementation of the project proposal, an investment project will be prepared in accordance with the Spatial Planning Act and Ordinance 4 of 2001 on the scope and content of investment projects. The investment project will include all mandatory energy saving measures prescribed in the energy efficiency audit, including measures for the utilisation of renewable energy sources and all mandatory measures prescribed in the technical audit. Energy renovation activities will prolong the life of the building, reduce maintenance costs and encourage people to stay in small settlements. As a result of their implementation will increase the energy efficiency of the building, reduce electricity costs, resulting in the release of resources to be redirected to other activities. Improving the energy efficiency of the building is one of the main prerequisites for improving the quality of the services offered, reducing energy consumption and protecting the environment.
