GERMAN PAVILION
ARCHITECT: SCHMIDHUBER+PARTNER LIGHTING DESIGN: E3
The German Pavilion is intended as a physi- cal representation of ‘the urban balance between volatility and stability’. With many German - and indeed European - cities see- ing a shift away from the suburbanisation of the past with a return to city-centre living, planners have been forced to create spaces that balance the needs of both work and domestic life. This model of ‘city in flux’ is equally true of World Expo host, Shanghai, with its modern malls and record-beating skyscrapers.
Dubbed ‘Balancity’, the German Pavilion seems at first glance to be constructed from a series of individual, unstable section. When viewed as a whole, however, these sections work together to support each other in perfect symbiosis. A silvery, transparent membrane, originally developed for shading façades, stetches over the entire steel frame to create a series of triangular planes. During the day, it supports climate control by reflecting up to 80 per cent of the solar radiation, ef- fectively reducing the generation of heat in- side. Though the building’s services systems and emergency staircases are all mounted on the exterior, the fabric hides them all away, creating a monolithic, sculptural ap- pearance.
The transparent quality of the membrane, a softly reflective surface that seems to absorb ambient colours, causes the pavilion to change its appearance depending on the time of the day and weather conditions. At night, the surfaces act as huge light screens, picking up the exterior lighting and reflecting it back into the surrounding area. Lighting designers E3

knew that if all these planes were illumi- nated equally, the pavilion would lose its special three-dimensional look. Instead the team, headed by Ulrich Kunkel, picked out a selection of the pavilion’s angular surfaces using Tesis inground spotlights from ERCO - a mixture of directional and wall wash- lights versions with either 35W or 70W HIT discharge lamps.
Certain areas, such as the ‘Germany’ sign, needed extra illumination and for these ERCO 150W HIT Beamer spotlights were used. Kunkel joined the project in the middle of 2008 as key consultant and designer for
Façade illumination comes from a combination of Tesis wall washlights (35W HIT) for the lower sections and Tesis directional spotlights for the upper areas (70w HIT). Both were mounted in the floor
