Investment and asset manager aam2core is continuing its modernisation initiative for the existing properties in its portfolio. During the EXPO REAL trade fair, two of the company's major office assets were certified for their sustainable operation by the German Sustainable Building Council (DGNB). The EDDI office building in Düsseldorf was awarded Gold, while the MARKGRAF25 property in Berlin achieved the highest rating level of Platinum in the Buildings in Use category.
The certificates attest to the quality of property management and the effectiveness of the measures already implemented to upgrade the buildings. The awards were based on a comprehensive future-viability analysis of both assets, conducted by aam2green Advisory GmbH, a subsidiary of aam2core Holding AG. On this basis, the ESG consultancy designed a tailored action plan and guided the certification process in close coordination with asset management.
Targeted modernisation and operational ESG processes
The DGNB assessment factored in both the completed refurbishment of the office space and the ESG processes embedded in regular operations. Energy efficiency at both locations is ensured by a combination of district heating, AI-supported heating optimisation, smart thermostats, and energy-efficient LED lighting. In addition, occupier comfort was enhanced through the creation of breakout areas, shower facilities with changing rooms, and optimised accessibility.
As Dr Thomas Worschech, Managing Director of aam2green Advisory, explained, the company translates DGNB certification requirements into operational property management measures. The Berlin asset MARKGRAF25 was originally targeted for the Gold category, making the award of Platinum status a particular confirmation of their approach. The certifications make the standard of implementation independently verifiable and demonstrate how sustainability expertise and hands-on asset management mesh together.
Sustainable management and full occupancy in Berlin
- —Establishment of green leases including binding sustainability guidelines
- —Implementation of a site-specific e-mobility strategy
- —Preparation of a long-term transformation plan for operations
- —Addition of structured waste management concepts and new communication zones
The MARKGRAF25 building is situated in Berlin's newspaper quarter in a central location between Gendarmenmarkt and Checkpoint Charlie. The quality of the space and the sustainable concept are also reflected in leasing activity: von Beust & Coll. Beratungsgesellschaft mbH & Co. KG secured 462 square metres of office space as part of a follow-on lease. For the tenant, the contemporary standard of fit-out and the flexible space layout were the decisive factors.
