Eva Samuel Architects and Associates designed this school in Paris, France and it is called École Maternelle. The building’s envelope is a response to several environmental aims: visual protection, increased natural light to counteract the surrounding solar screens, no thermal bridges, natural ventilation and double flux in winter. This school is the first to comply with the City of Paris’s climate plan. The result is a thick façade with varied reliefs – bay, alcove, and concave windows – which are used horizontally on the roof as skylights and to house air treatment machinery and ventilation chimneys. These multi-form strawberry-coloured elements enliven and dematerialise the façades. Their anodized aluminium cladding changes from pink to golden grey to green depending on one’s movements, point de view, the colour of the sky and reflections of nearby buildings.
