The number one cause of Global warming is architecture. Buildings are responsible for 40% of the Co2 that is emitted into the atmosphere. The architects must take this responsibility and move from geopolitics towards biosphere politics. A Green New Deal is a real test of how this can be achieved. The context for the intervention is an existing historic building in Barcelona, the Centre of Arts Santa Monica; a building to explore the Third Industrial Revolution as the potential of a transformation towards an empathic architecture. Nature should show us the path. Cloud 9 equipped the trees in front of Arts Santa Monica with sensors that capture data on temperature, humidity and light energy to inform the building. The intervention is an installation on the facade that produces energy from the environment, like the sun and wind. It is an additional skin which allows control of natural light and regulates solar radiation.
