machines (cleansing biotopes) that filter out pollutants in
the water. We are in downtown Berlin and there are small
birds and dragonflies flying about the site. "I had to fight
to have plants in the lake, to help clean the water, and to
keep copper flashing off the roofs," said Herbert. "The
'starchitects' on the project just wanted a reflecting pool
for mirroring the facades of their buildings but I won
Renzo's support." Italian architect Renzo Piano (California Academy of Sciences) was responsible for the overall
masterplan design of the site.
The lake has the second highest water quality in Berlin. The water continuously circulates via underground
pumps every three days in the hot summer throughout
the entire system, which contributes to maintaining its
incredible quality. The water also passes over structures
that oxygenate it, and that create a soothing ripple effect
on its surface. As we walk around the lake, I am amazed
when I see several large pike swimming in the clear waters. The fish are removed each year, but they somehow
keep coming back.
The green roofs and the lake help to reduce the urban
heat island effect, which averages about two degrees C in
Berlin. The lake provides a popular and valuable amenity
space to the workers in the offices of firms such as Sony,
Daimler-Benz and PricewaterhouseCoopers. The lake,
which is about 3 meters at its deepest, also invites people
to swim, although this is not a formally sanctioned use.
