Two German design teams collaborate to create artificial daylight in the basement of HSBC's Düsseldorf headquarters.

The enlightened renovation of a regional government building in Germany benefits from an ingenious daylighting strategy.

Bendorf, a rhine river city north of Koblenz, Germany, and a former center of mining and ironwork, acquired the derelict Sayn Iron Works Foundry in 2004 to repurpose it as a cultural attraction and an event space.

From the founding of their namesake monastery in 1145, the clerics of Santa María de Retuerta pursued Roman Catholic values of work, peace, and hospitality. Although monks have not occupied this corner of Spain’s Sardon del Duero area since 1931, contemporary visitors to their former abbey subscribe to the same principles, but in the reverse order.
