The number one cause of Global warming is Architecture - the buildings.Buildings are responsible for 40% of the Co2 that is emitted into theatmosphere. The architects must take this responsibility and move fromgeopolitics towards biosphere politics. A Green New Deal is a real test ofhow this can be achieved. The context for the intervention is an existinghistoric building in Barcelona, the Centre of Arts Santa Monica; a buildingto explore the Third Industrial Revolution as the potential of atransformation towards an empathic architecture. Nature should let us showthe path. Cloud 9 equipped the trees in front of Arts Santa Monica withsensors that capture data on temperature, humidity and light energy toinform the building. The intervention is an installation on the facade thatproduces energy from the environment, like the sun and wind. It is anadditional skin which allows control of natural light and regulates solarradiation.
