Climate-Friendly Architecture as a Design Driver
B-One reduces energy consumption by over 50% compared to its predecessor, achieved through integrated systems like photovoltaics embedded within the natural stone façade grid, geothermal heating systems, and concrete core temperature regulation within floor slabs. The decentralized underfloor hybrid ventilation, with heating and cooling functions, also allows users to choose between facade ventilation and natural window ventilation.

"In contemporary architecture, climate-friendliness cannot be an afterthought," Weyer emphasizes. "From the earliest design phases, we integrated sustainable systems as architectural elements that improve both performance and function."

The roof terraces and greenery hold back and delay rainwater, which is collected for reuse and cascades from terrace to terrace. This system ensures that rainwater never reaches the city's surface drainage system, with all stormwater managed within the building's landscape infrastructure.

Client Perspective
Sascha Klaus, CEO of Berlin Hyp and Board Member of LBBW:

"With 'B-One' we have created a pioneering building that provides our employees with optimal working conditions in every respect. In addition, it offers maximum flexibility in its spaces and, in line with our corporate values, meets the highest standards of sustainability. The successful realisation of the project is in no small part due to the professional work of our project partners, to whom I extend my sincere gratitude."

About the Project
B-One has a total gross floor area of approximately 19,000 square meters, spread across 13 floors, 11 of which are above ground. It offers flexible layouts with space for 500 workplaces for employees of Berlin Hyp and Landesbank Baden-Württemberg (LBBW). The two basement floors offer over 120 bicycle parking spaces and charging stations for electric vehicles, promoting sustainable mobility.
The ground floor incorporates areas designated for public use, including gallery spaces for art exhibitions, reflecting Berlin Hyp’s commitment to community engagement and cultural programming.

The building integrates its historical urban context with a contemporary design language, creating a work environment that embodies Berlin Hyp's values of transparency, innovation, and environmental responsibility.
