Implementation of an Innovative Model of the Comprehensive Energy Renovation Project of a Cultural Heritage Building in Ljubljana, Slovenia

[EN] Renovation of a building requires a comprehensive and targeted approach to managing the process from conceptual design to implementation and future use. Cultural heritage buildings are subject to specific legalities and restrictions in accordance with the conservation regime. The complexity of such a renovation process requires special knowledge and competence of the stakeholders involved. The key is constant and coordinated cooperation among the designer, the cultural heritage protection authority, the investor, the users, the supervisor and the contractor. This rationale inspired the creation of a model of the comprehensive energy renovation process, balancing heritage conservation with energy efficiency through nine key elements and quality guidelines, developed within the LIFE IP CARE4CLIMATE project. The model includes detailed steps of the renovation with quality guidelines for the conceptual design, inspection of the building's condition, financial planning, comparison of variant renovation measures, energy performance analysis and investigation of several other aspects, for instance fire and electric safety, earthquake resistance and the quality of the indoor environment. The model includes support to the investor in the preparation of tenders, contractor selection, supervision, and building management and monitoring plan. This innovative model has been successfully implemented in renovation of several heritage buildings in Slovenia. A more detailed description of its implementation in practice is presented on an award-winning renovation project of heritage building in Ljubljana, Slovenia.
