The bienniale „fundamentals“ took place in the summer of 2014 in Venice. The exhibition was curated by the dutch architect Rem Koolhaas. Within the exhibition concept, architecture as such was broken down into its elements. In addition to the wall, the floor and the ceiling, a part of the exhibition was dedicated to the building envelope. The development history of the facade was illustrated by its concise innovations. The development status was represented by components of recent project examples, such as the façade xy by xy.
