Is the dynamic façade set to become the great architectural trend of the end of this decade? If so, copper has a prominent role to play in the revolution. Durable, malleable and scalable, it is a material of choice for architects who innovate in designing functional cladding. The judges of the European Copper in Architecture Awards 2017 can testify to this fundamental tendency: four of the eight Shortlisted buildings have dynamic facades. These no longer simply act as envelopes. In the form of copper sails or strips, they are able to better manage light and heat, and improve the energy performance of buildings. In the form of a raw surface that evolves over time, the façade gives life to a building and becomes the key to its environmental integration.
