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.
