The dynamic building envelope able to vary the performances in relation to the climatic stresses and to the user’s needs, represents one of the main technological trends of the last decades, aimed at implementing the energy efficiency of the buildings and the internal environmental comfort. In this scenario, a challenge that is still open is the creation of dynamic systems that are easy to use, manage and maintain with reduced manufacturing and management costs. The article intends to describe the research process that led to the design of an innovative external shielding system that can be orientated and moved automatically, at low cost and easily produced, thus allowing simple and economic management over time
