About
Building on the open field gives the place a centre where the two meet.
The S-shaped plan forms three 'living rooms' and frees space for a public park and square. The school is meant to bring together its pupils and the people of the district.
It is a simple building with a compact form, a timber-louvred facade and a strong energy concept.
Sustainability
A very efficient envelope and compact form limit energy losses, south-facing glazing gathers passive solar gain, and double-flow ventilation recovers heat. Solar thermal and photovoltaic panels over more than 3,800 m² of roof cover most of the remaining demand, with a connection to the Sion district heating network.
