Energy-intensive building

The building of Alzingen school, built in 1968, needed to be renovated and compliant to current standards, particularly in terms of accessibility and energy performance. Following exchanges with all stakeholders, we have reached the following program:

• Renovate and clean up the building from an energy and environmental point of view

• Assign Alzingen School in the early teaching and cycle. 1.

• Add a kindergarten with food production.

• Make schools accessible to people with reduced mobility.

• Renovate the gym / multipurpose hall

• Adapt the hall additional rooms to the needs of the clubs that use it.

• Add a music studio, a library, a conference room and a DIY studio.
