aam2core receives DGNB Platinum certification for MARKGRAF25 and Gold certification for EDDI
Stefan de Greiff (Board Member) and Dr. Thomas Worschech (Head of ESG & Sustainability) accepted the DGNB certificates on behalf of aam2core Holding AG.
Frankfurt am Main, November 10, 2026 – Investment and asset manager aam2core is further advancing its modernization initiative for its managed portfolio: The EDDI office building in Düsseldorf and the MARKGRAF25 in Berlin have been certified by the DGNB (German Sustainable Building Council) in the "Buildings in Operation" category. EDDI received the Gold award, while MARKGRAF25 achieved the highest level of certification, Platinum. The certificates, presented at EXPO REAL, confirm the quality of building operations and the measures already implemented to further develop both properties.
aam2green Advisory GmbH – a subsidiary of aam2core Holding AG – analyzed the two buildings for their future viability and, based on this analysis, developed a customized action plan. The ESG consulting firm supported the certification process in close collaboration with aam2core's asset management team. The assessment focused on the quality of building operations, taking into account the completed modernization and the ESG processes already established in building management.
“We translate the requirements of the DGNB certification into concrete measures for the management and further development of each property. For MARKGRAF25, we had originally aimed for Gold, which is why the Platinum certification we achieved is a particular confirmation for us. Both certifications make the quality of the implemented measures independently verifiable and demonstrate how sustainability expertise and practical implementation interlock,” says Dr. Thomas Worschech, Managing Director of aam2green Advisory.
The modernization of the office spaces in both buildings is complete. District heating, AI-supported heating optimization, smart thermostats, and LED lighting support energy-efficient operation. Showers with changing rooms and lounge areas are available for users. Accessibility has also been improved.
Both properties include green leases with sustainability guidelines, an e-mobility strategy and a management transformation plan.
At MARKGRAF25, communication areas and a structured waste management system complement the building's operations. The property is located in Berlin's newspaper district between Gendarmenmarkt and Checkpoint Charlie. Von Beust & Coll. Beratungsgesellschaft mbH & Co. KG leased 462 square meters as part of a follow-up lease. The decisive factors were the furnishings and the flexible floor plan.
