Description
The Erlenmatt school
building in Basel opened in 2017. Its defining feature is the terraced outdoor
spaces, which, together with the ground-level playground, are being adapted to
future climate challenges. The original 2012 concept envisioned robust,
partially sealed surfaces, which limited the number of trees that could be
planted. Although a total of 40 trees were planned in 2014, these could not be
realised. In light of climate change, this decision is now being revised: 35
new trees will be planted, and the amount of sealed surface area will be
reduced. Existing paving will be partially removed to create tree pits, while
the rest will be retained and selectively enhanced with colour. This will
create a shaded area that, through evaporative cooling and shading, will help
reduce summer heat and continue to offer a variety of recreational activities. The
terraces of the stepped building are designed as breakout and classroom spaces
and are being used as such. To better utilise the terraces for teaching
purposes, creating an open-air school environment, we have designed shade
roofs. Detailed studies revealed the advantages of louvred, air-permeable,
shade-providing elements, which the architects developed as a reuse project, making
a clear statement. The result is a spatially precise placement of the shade
roofs at different levels within the multi-award-winning project
