In Basel, the transformation of the Gundeldinger Feld marks a significant shift from traditional fossil fuel reliance towards renewable energy. A striking example of this change is the former coal silo and heating plant of Sulzer Burckhardt AG, which has been innovatively clad with coloured photovoltaic (PV) modules. This project not only highlights the site’s industrial heritage but also serves as a cutting-edge research platform for Building-Integrated Photovoltaics (BIPV). Researchers are exploring new materials, integration strategies, and energy storage solutions through this initiative. As part of the heritage-protected Gundeldinger Feld, the renovated structure harmoniously blends with the existing architectural style and colour palette. This adaptation is part of a broader transformation of the old industrial area into a pioneering model energy district, showcasing a sustainable approach to urban redevelopment.

What is the Solution?

The photovoltaic (PV) solution described features innovative, coloured, customized photovoltaic modules that not only serve an energy-generating function but also contribute aesthetically by forming a unique visual design. These modules are specifically designed to integrate seamlessly into the ventilated roof and façade envelope of a refurbished historical industrial building, enhancing its appearance while preserving its architectural integrity. This approach ensures that the building remains environmentally sustainable and visually appealing, representing a harmonious blend of tradition and modern renewable energy technology.

Why Does it work?

The PV solution works effectively in the "Gundeldinger Feld" redevelopment project primarily because it adheres to the stringent requirements set by the heritage protection status of the site. This status mandates that any modifications or additions to the buildings within the ensemble must closely align with the existing architectural style and colour schemes.

PROS

By ensuring that the solar panels and related infrastructure are designed to blend seamlessly with the historic aesthetics, the PV solution not only respects the cultural and historical integrity of the area but also integrates modern renewable energy technology without compromising the visual harmony of the protected site.

CONS

Maintenance and Replacement: Customized solutions might pose challenges in terms of maintenance and replacement. If a panel requires replacement due to damage or efficiency loss, sourcing an identical module could be difficult and costly, given their bespoke nature. Regulatory and Design Limitations: Adhering to stringent heritage protection standards can limit the scope of technological innovation and the scale at which it can be applied. This could result in a less optimal PV solution in terms of energy output and technological advancement.
