Make the façade a lever for comfort.
Kelveen is being developed to act on the existing opening, in step with the sun and the seasons.
Why look at Kelveen?
Because the comfort of a room is also decided at the window — where light, heat and daily use meet.
Start from what is there.
Explore a targeted intervention on the opening, suited to the building already standing.
Keep control.
Automate the useful changes without taking the choice away from the occupant.
What it means for the building.
The four questions we get asked first, with today’s answer — including where there isn’t one yet.
No structural work.
The work is confined to the existing opening. No structural alterations, no change to the building envelope.
The building stays occupied.
No rehousing, no site closure during installation. The spaces remain usable.
It is reversible.
The installation can be removed. If the trial does not convince, the building returns to its previous state.
The cost is not established.
We do not know it yet, and we would rather say so. It is one of the things a first pilot has to determine.
