Germany - Traditionally utilities are housed in functional buildings, often outside of town, away from the scrutinous eye of urban dwellers, but not always. Centrally located in the city of Leipzig is the gas and steam cogeneration plant, GuD Heizkraftwerk. Owners Leipziger Stadtwerke GmbH sought to integrate the building with the more aesthetic structures of Leipzig's architectural centre and thereby positively influence the city's night time image. Commercially, the company wanted to visually brand the cogeneration plant with the yellow and blue logo of Stadtwerke Leipzig. In November 2003 the company presented IPRO Leipzig with a draft and implementation plan that called for a unique night time lighting concept that could achieve these goals.

Lighting artist Jürgen Meier was subsequently contracted and worked with Armada Signs, the leading lighting promotion company in central Germany, on a striking illumination concept that emphasises the facade structure and architecture of the boiler house. The illumination consists of 12 Martin Architectural Exterior 600 and four Martin Exterior 200 colour changers located around the building which render the building's finely drawn grid structure visible in tones of blue and yellow. The luminaires powerful illuminant and optimised optical characteristic provide an even wash across the building while the fully programmable colour mixing system makes a nearly limitless spectrum of rich colors available. Technical aspects of the illumination were handled by Heinrich Müller of Licht-In-Form of Dresden.

Stadtwerke Leipzig has been upgraded enormously by Jürgen Meier's lighting design and now stands as a key feature of the city's night time skyline. In fact, the gas and steam turbine building could be mistaken for the town's newest high rise hotel.
