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.

Albedo operational

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.

1,2tCO₂e/an

The 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.
