A cylindrical, distinctive building in the middle of the town square is an urban plan¬ning motif with roots in the Italian Renaissance. The form offers lots of floor space in relation to the amount of exposed exterior wall surface, and the upper floors project out over the lower—more on the south side than on the north, so that the building par¬tially shades itself when the sun is high in the sky. A rotating screen shades the top floors, following the sun’s path around the building. The triangu¬lar-shaped windows let in the light where it’s needed most—by the ceiling, from where it can reach deep into the core of the building.
By equipping the building with motion-activated lighting and ventilation sys¬tems, energy is used only where it is really needed. The result is a building with a calculated energy consumption under 55 kWh/sqm annually.
