Two discreet, high-performing rooftops now produce clean energy right in the historic heart of Crissier.

In the heart of Crissier, within the protected zone of the historic town centre, the municipality carried out an ambitious renovation and construction project around the Château de Crissier. The challenge: integrating modern energy solutions without compromising the architectural identity of an exceptional site.

As owner of the surrounding land, the municipality chose to renovate the château into apartments and build two new residential buildings on the adjacent plots. To preserve the character of the site, architects of the residential buildings received a clear brief: find solar tiles capable of blending seamlessly with the existing built environment.

Lausanne-based firm L-Architectes selected our Solaris™ V Diamond Terracotta tile for its terracotta hue, perfectly suited to the traditional aesthetic of the site. Both buildings were oriented north-south, with solar roofing installed exclusively on the south-facing slopes, a technical and aesthetic choice that maximises output while keeping the installation discreet. Metalwork was carried out with precision by Phida.

The main roof is 361 m2 and has a power of 32,51 kWp
the second roof is 252 m2 and has a power of 22,72 kWp

This project demonstrates that heritage requirements and the energy transition are not at odds, two discreet, high-performing rooftops producing clean energy right in the historic heart of Crissier.
