Le schermature solari svolgono un ruolo chiave sia in relazione alle prestazioni energetiche dell'involucro edilizio sia per il comfort degli utenti. Questi sistemi di schermatura possono essere sia statici sia dinamici e possono avere differente posizione (esterni, interni), giacitura (verticali, orizzontali) e regole di attivazione. Oggigiorno i sistemi dinamici sono i più utilizzati e sono attuati da componenti elettro-meccaniche. Un'attuale scuola di pensiero propone, come alternativa ad un'attivazione basata sui motori, l'utilizzo di Smart Materials (SMs) in quanto meno complessi e più energeticamente efficienti, riducendo quindi il "risk of failure" del sistema e i consumi elettrici. Partendo dall'analisi dello stato dell'arte è stato svliuppato un nuovo sistema basato su un sistema di attuazione con Shape Memory Alloy (SMA). L'obiettivo del sistema sviluppato è stato l'ottimizzazione dei consumi energetici e del Daylighting riducendo anche "risk of failure" ma mantenendo un elevata flessibilità del sistema (in termini di materiali, forma e posizionamento).

Abstract
Shading devices plays a key role in the building envelope in term of performance, but also in users’ comfort. These systems can be both static and dynamic and can have different positions (external, internal), multiple arrangements (vertical, horizontal) and activation rules. Nowadays dynamic systems are the most preferred and are based on electric-mechanical systems. A current school of thought considers the introduction of smart materials (SM) as an alternative to motors as these are less complex and more energy efficiently reducing the risk of failure and energy usage. From the existing research, a new shading system based on Shape Memory Alloy (SMA) has been developed. The aim of this system has been the developement a shading system that optimize energy and daylighting performance reducing risk of failure and allowing high flexibility (custom system) in term of materials, shape and placing (Inside, outside).File | Dimensione | Formato | |
