“Feed the planet – Energy for life” is the slogan which expresses the central theme of Expo 2015 in Milan. The world fair is intended to show the links between technology, innovation, culture, tradition, creativity and the subjects of nutrition and food.
The Expo theme also prompted the exhibitors to find architectural solutions for the numerous exhibition structures which are sustainable and environmentally compatible. Two pioneering examples are “Pavilion Zero” and the structures that provide entrance pathways throughout the exhibition areas. They were distinguished by a combination of resource-saving construction methods and the use of sustainable, reusable materials.
The pavilion, which was designed by Michele De Lucchi, has an area of 7,500 m2 and serves as an introduction to the central theme of the EXPO. It consists of eight cones with diameters that vary from 85 to 45 m and with a maximum height of 26 m. The pavilion’s design calls to mind the Euganean Hills, which lie South-West of Padua. The wave-form structure has a façade made from horizontal wooden slats, which are fastened to a hot dip galvanized sub-frame. The entire steel load-bearing system of the pavilion was also hot dip galvanized. This was no accident, as the pavilion is meant to be reused after the Expo. Galvanizing will withstand the rigors of dismantling and re-erection of the steel structure and also be recycled at end of life.
Expo approach pathways
The EXPO’s approach pathways that weave their way through the complex are distinguished by their minimalistic design. They act as part shelter for the main routes on the Expo site, and give an impression of sublime lightness. Slender steel columns in combination with taut cable systems form the supporting framework for the membrane webs of the roofing structures. The sizes and the geometrical shapes of the roofing structures vary, depending on their location and whether they are on main or secondary routes. One common feature of the roof structures is that all steel components are hot dip galvanized and subsequently coated.
