Heidelberg Energy Storage Tower


Heidelberg Energy Storage Tower, Germany


Pfeifer Structures for Stadtwerke Heidelberg (SWH)

Project Vision

Combine highly complicated engineering with a myriad of non-standard steel components and the result is Heidelberg’s iconic new energy storage tower.

Making global headlines for its design and commitment to sustainable energy, the landmark project demanded precision at all levels.

Featuring public viewing terraces and a restaurant offering some of the best views in the city, the design includes over 450 tonnes of steel members and cabling encasing a giant cylindrical-shaped water tower.

Sending a strong message about the transition towards renewables, Heidelberg’s newest landmark and tourist attraction also includes a knowledge centre for sustainable energy.

With energy generated on-site used to heat up the water in the tower, surplus energy can be supplied to thousands of local households.

The building design highlights the complex interplay of movement, light and shadow generated by sun and wind, with no additional energy or complicated technology required.

The Multiplan Difference

Multiplan was appointed to provide construction modelling services, ensuring the challenging, multi-faceted façade of Heidelberg’s newest landmark came to life with pin-point accuracy.

The all-important link between the architect’s intricate, cutting-edge design and the building’s various structural steel components, our team engaged directly with the client to translate the extremely complicated engineering into a fully-resolved digital model.

As well as bringing our 3D modelling expertise to the new tower’s cables, precambered frames, helical staircase, tension rods, bearings, twisted beams and cladding, our scope of work also included assisting with the process of fabrication and erection.


By partnering with the client, architect and engineers in an early engagement capacity during the design phase, we were able to resolve especially complex details before the project proceeded to the steel fabrication stage.


The Multiplan team brought 6000 - 7000 man-hours to the project over a period of about five months.


A collaborative approach resulted in custom workflows and communication channels, all supported by an English-speaking team of 3D BIM experts based in Multiplan’s European office in Bulgaria.

Our team’s in-depth knowledge of digital engineering and steel fabrication helped translate details such as arches, helixes and spirals into 3D reality.


Multiplan is proud to have collaborated on the Heidelberg Energy Storage Centre with engineers SBP and LAVA (Laboratory for Visionary Architecture) on this project.
