The development of adaptive architectural envelopes is one of the goals of researchers that aim to improve the energy performance of buildings. Traditional devices often have drawbacks linked to the complexity of the kinetic systems used, as the mechanical systems for guaranteeing proper operation are complex and expensive (e.g., hinges). Adaptive envelopes require energy for driving the mechanical components and management systems. Thus, it is useful for such adaptive elements to be self-sufficient, generating the energy necessary for their functioning. This study presents a prototype of a lightweight and stand-alone component for dynamic envelopes, characterized by a flexible composite material integrated with high-efficiency photovoltaic cells called the Solar Lightweight Intelligent Component for Envelopes (SLICE). The management and control of the SLICE is based on the Arduino platform. This paper describes the multidisciplinary design process that led to the realization of the current prototypes, the laboratory test phases, as well as the results of the preliminary experiments carried out under real environmental conditions.

ICARO (Innovative Cardboard ARchitectural Object) is a type of innovative building technology developed by a working group at the University of Catania, within the framework of the EWAS (an Early WArning System for cultural heritage) research project. It represents a tool for used to combat climate change thanks to the high level of sustainability of its component. The modular component based on ICARO technology is a pre-fabricated panel for building vertical envelopes, consisting of a laminated wood frame that contains corrugated cardboard boxes. In order to improve the panel’s structural performance, a pre-stress procedure has been adopted. The panel is cost-effective and boasts a high level of sustainability thanks to the use of lightweight, pre-cast, recycled, and recyclable materials. This technology is suitable for the construction of micro-architecture in fragile contexts. In order to test its performance, a full-scale prototype called the EP (Experience Pavilion) was built within the Megara Hyblea archaeological area in Sicily, which was chosen as a test site. A campaign to be carried out at the EP is currently being planned, which will focus on various issues. This paper describes the design of ICARO technology and the construction of the EP prototype.
