The funded project ‘Smart Energy Hub Düsseldorf/Mettmann’ addresses key challenges of climate protection and the energy transition, including the heating transition and the energy-efficient refurbishment of existing buildings in the Düsseldorf and Mettmann region. As a result, ‘SEH-DUS’ aims to develop needs-based solutions for the energy and heating transition and thus contribute to the sustainable transformation of the region. The project focuses on the further development and implementation of virtualised tools for use in building and energy management by small and medium-sized enterprises.
