The concept for the new international airport of Zagreb in Croatia has been designed by De Architekten Cie as part of a competition. The architects have tried to create the most sustainable airport possible with lightweight tensile structures as the starting point.\u00a0 In collaboration with ARUP they developed a triple layer tensile roof which spans between major structural arches of concrete.\u00a0 The\u00a0thickened membrane roof is an attempt at creating a performative pocket since it serves multiple functions:<\/p>\n
Furthermore the concrete arches supporting the membranes\u00a0are thermally activated to\u00a0both heat\u00a0and cool the terminal building depending on the season.\u00a0 Within the building and site plan there are a host of other sustainable measures, far too long and boring to describe here.<\/p>\n
