Abstract

L'invention concerne des systèmes de façade destinés à produire de l'énergie, en particulier des systèmes de façade dans lesquels une énergie éolienne, présente en raison d'une poussée aérostatique, est convertie en énergie électrique. L'invention vise à produire de l'énergie tout en améliorant la rentabilité, y compris les jours sans vent. A cet effet, un système de façade (10) destiné à produire de l'énergie présente une structure de façade (12) pour un bâtiment, ladite structure comportant une face intérieure (16) tournée en direction d'un espace intérieur et une face extérieure (20) tournée en direction d'un espace extérieur. Le système de façade comporte en outre au moins une gaine (22) s'étendant verticalement et au moins un générateur (24) doté d'un rotor (26). La gaine est disposée à l'extérieur de la face intérieure et s'étend sur au moins une partie de la hauteur de la structure de façade et est reliée à l'espace extérieur par une ouverture d'entrée d'air (27) dans la zone inférieure et par une ouverture de sortie d'air (28) dans la zone supérieure. Le rotor est disposé dans la gaine entre l'ouverture d'entrée d'air et l'ouverture de sortie d'air et sert à convertir l'énergie éolienne, présente en raison d'une poussée aérostatique dans la gaine, en énergie électrique. Le ou les rotors sont maintenus sur une structure porteuse (32) dans la gaine de manière à pouvoir être retirés.
