A combination of the German word for energy — energie — and the name of the building material company — the Gienger group — that occupies the space, ENER[GIE]NGER is innovative retail and exhibition space that uses the latest sustainable technologies. The 2,600-square-meter (28,000-sf) space is a helix-shaped building clad entirely in solar and photovoltaic panels, glass, or metal elements. Serving as the showroom and outlet for Gienger products, the spiraling building structure forms a glittering point of attraction within an otherwise ordinary industrial park in Munich, Germany.
