B-One

Berlin Hyp's 13-storey office building in Berlin-Tiergarten combines modern architecture with the highest sustainability standards and offers space for around 500 workstations.

With innovative building technology, smart room concepts and a targeted DGNB platinum certification, the project is setting new standards for sustainable construction in the capital.

Sustainable new building in Berlin: Ed. Züblin AG realizes modern office building for Berlin Hyp

Berlin Hyp's new office building at Budapester Strasse 1 in Berlin-Tiergarten with a gross floor area of 19,104 m² and a building height of 44.79 meters offers space for around 500 modern workplaces. The 13-storey building - 11 of which are above ground - is part of Berlin Hyp's comprehensive sustainability strategy and was designed by Danish architecture firm C.F. Møller Architects. The design follows a clear, functional design approach that combines Nordic aesthetics with user-friendliness and ecological responsibility. As the client's representative, bdp real estate GmbH was responsible for quality assurance and project management - from concept development and the planning phase through to construction. A remarkable milestone was already achieved during the demolition of the previous building: a recycling rate of 88% - a top value in a nationwide comparison - was achieved and awarded the DGNB platinum certificate for the demolition. DGNB Platinum certification is also being sought for the new building, as well as Diamond certification for the remarkable architecture.

Innovative measures for maximum sustainability

Geothermal plant with 60 deep boreholes for efficient energy generation
Photovoltaic modules in the façade to generate electricity from solar energy
Green roofs and façades that help to promote biodiversity and improve the microclimate
Smart building technologies that enable intelligent control of energy consumption, lighting and indoor climate

These measures not only make the building particularly environmentally friendly, but also sustainable in terms of operating costs and resource conservation.

Digital construction management with BIM and lean management

The entire project was implemented on the basis of a Building Information Modeling (BIM) process. From planning to execution, the project was managed digitally, resulting in a high level of transparency and efficiency. This approach was complemented by consistent lean management on the construction site to ensure on-time completion, cost certainty and high quality.

Flexible and modern working environments

The new office building not only offers space for all Berlin employees of the LBBW Group, but also a working environment that meets the requirements of modern office structures. The room concepts are flexible and promote both collaboration and concentrated work:

Open-space areas for teamwork and communication
Workshop and creative spaces for agile working methods
Retreat areas for focused work
Townhall as a central meeting space with open staircase and integrated library wall

The Townhall extends over several levels and creates an open, communicative atmosphere. Directly adjacent is the company restaurant with access to the landscaped terrace in the inner courtyard - a place to relax and meet at any time of year. On the second floor, there are conference, workshop and office areas that can be used flexibly.

Certified by the German Sustainable Building Council (DGNB)

Ed. Züblin AG is pursuing several goals with this project: A sustainable construction site organization, the conservation of resources as well as the minimization of emissions, responsibility for the health and well-being of the builders, the cultivation of good neighbourliness and, of course, high-quality construction. For this, Ed. Züblin AG was the first company to be recognized by the German Sustainable Building Council (DGNB).

Selected measures in the project

Finished parts

The extensive use of prefabricated parts (cavity walls, stairs) means that a shorter construction time can be achieved. The volume of waste is also reduced thanks to the prefabricated orders.
Concreting

Concreting, for example ceilings, is carried out using a concrete pump, which is continuously filled with concrete by truck mixers and ensures rapid completion of the component thanks to its high performance. Ready-mixed concrete is used for concreting. This eliminates dust emissions caused by mixing concrete on site. All of our supplier's cement plants have been awarded a CSC gold certificate.
Saving resources and reducing emissions through LEAN Construction

As part of the lean approach, a production plan with call-off dates (e.g. insulation) was created. Construction production planning is detailed on a weekly basis and adapted to actual production progress. Changes in the construction process are constantly taken into account and just-in-time deliveries can be better implemented. Repeat orders and new orders due to late changes to the plan are avoided.
Measures to prevent pollution from the construction site

The project is located in the city center, so the impact of the construction site will be avoided or reduced as much as possible.
Energy management in construction

Construction site investigations and comparative considerations for the most energy-efficient project execution possible. For example, selection of a large concrete bucket to reduce the number of lifts.
