Environmental performance was essential in the design of the British Junior School in s- Gravenhage, Netherlands, created by Kraaijvanger-Urbis Architects. The south façade is key to the building's performance -- both educational and environmental. To facilitate a friendly atmosphere inside, the south façade curves to give children in the classrooms attractive views out to the central garden. And for solar control, the façade also features an advanced set of sun louvers from Hunter Douglas. On chilly winter days, the louver system allows solar energy to enter the building. In warmer summer months, however, the louvers deflect the sun and reduce heat gain. This approach fits right in with the environmental values of the Dutch, which place the country among the greenest in Europe.
