Berlin Hyp - New Headquarters, Berlin, Germany

Transsolar supported the holistic sustainability concept of Berlin Hyp’s new headquarters by developing the building’s energy, ventilation, and utility systems. The project meets the highest sustainability standards, and the deconstruction of the old building was an integral part of the overall project.

The building is located in the immediate vicinity of the Landwehr Canal and the Zoological Garden. As a corner building, it is flanked by Budapester Straße / Lützowufer and Keithstraße. The new building has 11 above-ground stories, primarily used as office space, as well as two basement levels.

Densely planted terraces, combined with a self-shading facade, reduce solar radiation and contribute to a pleasant indoor climate. Transsolar developed the building’s energy, ventilation, and utility systems. The building is climate-controlled via structural heat recovery with an occupancy rate of approximately 60%. For specific areas with increased cooling loads, cooling ceilings were additionally installed over an area of approximately 2,800 m².

The building’s electricity is supplied primarily from the public grid. A photovoltaic system covers approximately 20% of the electricity demand. In addition, 60 geothermal boreholes were drilled to a depth of just under 100 meters, providing approximately 75% of the required heating load as well as the majority of the cooling load. Based on these parameters, the building meets the criteria of the EU Taxonomy following an assessment, which represents a key sustainability goal for the client.

Decentralized electric instantaneous water heaters are used for hot water in the office areas, thereby avoiding extensive installation work for hot water pipes and circulation systems. The catering kitchen has a central hot water system. In addition, a rainwater collection trench was installed so that rainfall can be used both for watering plants and for direct recharge into the groundwater.

During the demolition of the old building, the bank placed great emphasis on environmentally sound disposal and the recycling of materials. Small pieces of furniture, materials, and technical equipment that were no longer needed were donated to schools, sports clubs, the volunteer fire department, and other institutions, or auctioned off to enable their continued use. The proceeds from the auction benefited nonprofit organizations.

Compared to the existing building, the new building’s energy consumption was reduced by more than 50%. This result underscores the effectiveness of the integrated energy and building concept and confirms Transsolar’s commitment to implementing sustainable solutions with a high standard of comfort. Our successful participation in this forward-looking building project exemplifies our guiding principle: High Comfort Low Impact.

The new “B-One” building was awarded DGNB Platinum and Diamond certifications, confirming both its outstanding sustainability performance and its high architectural quality. The demolition of the existing building had already been awarded the DGNB Platinum Certification for Deconstruction.
