Prototype in development
The shutter that works with the sun.
Kelveen works with reflected light: it makes use of low winter sun, redirects it in summer and exposes its photovoltaic face when the opening is cleared.
A year in motion
Three seasons.
One façade.
The project today
The simulation exists.
Now for the proof.
Albedo, our energy simulator, is operational. It compares a building with and without Kelveen, hour by hour. The simulation must now meet materials, measurement and a first building.
A moment to take it in
One potential.
Two scales.
Albedo provides an order of magnitude, then returns to the case that matters most: your building.

cas cible simulé à Bordeaux Test my buildingThe first figure describes a favourable case, not a national average. The second is a theoretical potential, not a commercial forecast. Both still require experimental confirmation.
The simulation exists
Now measure the real world.
The next step is clear: protect the invention, measure a prototype and instrument a first building.
