Description
The idea was to develop a calm, strong overall form
that could integrate the different areas of the solid waste incineration plant:
the delivery section and the process bunker. The power plant is organised into
two distinct elements: a solid plinth that houses the main infrastructure and
the machinery positioned above it. This configuration enhances the legibility
of functional relationships while balancing the overall proportions. Resting on
the massive base, the technical facilities are enclosed in a lightweight shell – akin to the bodywork of a car. A continuous band of glazing marks the
transition between these elements, emphasising their contrast while offering
glimpses into the impressive machine hall. The chimney emerges from the plinth,
rising alongside the process hall to a total height of 80 metres. At its peak,
a viewing platform introduces an unexpected yet distinctive architectural
gesture, giving the structure a striking and unique detail. The volumetric
composition takes the form of a sculptural concrete entity, unifying the
various functional components into a singular architectural expression. Within
this sculptural framework, the process hall serves as both the functional and
conceptual epicentre of the complex. Here, the production processes and
technological infrastructure become the visible driving force behind the entire
facility. As a result, the building asserts itself as a bold and identifiable
landmark within the expansive Aare landscape at the southern foothills of the
Jura.
