The Merck Modular Innovation Center in Darmstadt, Germany, is home to pioneering sustainable design features which are now being tested.
Reddish louvres, which provide protection against the sun on the southern sides of the structure, consist of dye-sensitised solar cells that produce enough electrical power for a one-person household.
And the western façade includes a frontage with smart liquid crystal windows designed by Merck. Molecules in the high-tech coating of the windows act as microscopic venetian blinds. The windows can be darkened at the press of a button to protect the conference rooms from daylight, without any adverse effects on outside views.
