Courtyard, Technical University / Berlin. As part of the lighting design for the reconstruction of the glass roof above the courtyard at the Technical Univer- sity in Berlin (Pitz & Hoh, 2003) a modern frieze was to be designed to replace the projecting wood frieze destroyed in the War. In terms of shape the new frieze references the original and transforms it into a light, bright element made of lasered, corrugated stainless steel elements. By day the sheets have a gold sheen created by the reflection of the gold-colored rear. At night the frieze is illuminated from the opposite side and serves as a reflector. A circular luminaire consisting of 64 cylindrical holders forms the outer edge of the domed glass ceiling.
