The building’s form follows two principles: achieving a cohesive overall shape and clearly organizing its functions. A solid plinth houses the main infrastructure, while a lightweight shell above encloses the machinery, with a glazed band marking their transition and revealing the machine hall. From the plinth rises an 80 m chimney with a viewing platform as a striking gesture. The sculptural concrete composition unifies all elements, making the process hall the functional and conceptual core and establishing the facility as a bold landmark in the Aare landscape.
