Bâtiment haussmannien à Paris - Facades only - Efficiency: 20% - CALECHE Solutions

The Building

Bâtiment haussmannien à Paris

Historic Hausmann-style building in Paris, in a district whose Hausmannian unity is to be preserved.

What is the Solution?

Thanks to Kromatix coloured solar glass technology, the panels could be integrated into the façade in a trompe-l'oeil effect (the windows are solar panels), while respecting the Hausmanian unity of the neighbourhood.

Why Does it work?

This solution makes it possible to generate clean energy while preserving the aesthetics of historic buildings, by integrating perfectly into the existing urban fabric.

PROS

The photovoltaic modules have been entirely designed to meet a very specific need and to fit into a particular context.
