»The walk-on storage facility provides Heidelberg with a future-oriented landmark, which technically and aesthetically symbolizes the energy transition and makes it accessible.«
IBA advisory board

Together with its customers and partners, Stadtwerke Heidelberg is driving forward the local energy transformation. One component of their »Energy Concept 2020/2030« will be the storage facility for energy and the future. The new 55-metre-high walk-on heat accumulator impressively demonstrates the relevance of sustainability and climate protection. Furthermore, the architectural attractiveness makes it possible to create a public meeting place that embodies the importance of energy production: suitable for everyday use, at an authentic location.

For the ambitious infrastructure project, the client, in cooperation with the IBA, invited entries for an international design competition after an application procedures. This was preceded by intensive urban planning coordination and technical concept development.
In 2016, a jury selected three winners from 14 submissions for the facility. The winner — LAVA, Berlin — has since been commissioned with the planning, a building permit was granted, and a symbolic ground-breaking ceremony was held. Construction of the heat storage facility will start in 2018. It will be open to the public with a viewing platform and a restaurant. Interactive displays will help to understand and experience the energy transition. In cooperation with its future neighbour — the Heidelberg-based orthopaedics and rehabilitation technology company adViva — the building will be embedded in a publicly accessible park of energy and movement for customers and visitors.
