The volume, part of the Contemporary  Works of Architecture series, is dedicated  to the UBPA (Urban Best Practice Area)  pavilion realized by Studio Archea in  China on the occasion of the Expo 2010  in Shanghai, within the cooperation  program between the Expo and Italian  Ministry for the Environment. The project  represents an extraordinary opportunity  to highlight the most modern ways to  conceive architecture, on the basis of an  approach that respects the environment,  saves energy and considers the impact,  in terms of quality and aesthetics, of the  architecture on the landscape. The pavilion  is a simple container, a neutral box that  has been transformed into a mechanism  for diffusing natural light without any need  to consume energy, realized with a steel  structure assembled mechanically without  cement, something which makes it possible  to disassemble and reassemble the volume,  rapidly and efficiently, in another location.
