Rainwater is of crucial importance here. All the water that falls on the roofs, flows through various cleaning phases into a tank with a capacity of just under 300 cubic meters, and is pumped from there into two circulating systems. The first is used to supply the plants in the greenhouse. South American vegetation grows in one section, Australian in the other, and both provide a landscape with water courses and ponds.
These conservatories face south and southwest, and are part of the passive solar energy use concept. High temperatures in the summer created a need for a second circulating system. Here the pump dispatches water to six water walls, which has a number of positive effects. The walls are suspended without frames, and glow in fascinating colors, particularly at night.
