Picture of Arduino powered Moss&Solar Facade Element

The idea behind this unique facade element is to produce power AND to filter fine dust. We planed it to function autonomously and react to high fine dust pollution.The facade element is made of three rotating prisms.

The different surfaces of each prism are covered with moss, which can filter the dust out of the air, and photovoltaic modules to produce power. Sensors are use to control the automatic rotation of the element depending on the air quality. If the moss gets too dry the element will be turned to put the moss into the shadow at the back of the module.

This project was part of Multimodal Media Madness 2014, hosted by the chair for Computer Aided Architectural Design (CAAD) and the Media Computing Group of RWTH Aachen University. For more Thinking Skins, please check this page:
