This paper presents a study about the integration of Piezoelectric Energy Harvesting Systems (PE-EHSs) into building envelopes for powering Fiber Bragg Grating (FBG) sensors, enabling efficient and low-consumption monitoring with objective leveraging structural health (SHM). The research includes preliminary tests conducted in real environment to validate PE-EHS when fully integrated ventilated façade, capturing mechanical vibrations generated mainly by wind loads. Based on these activities, final configuration PE-EHSs is defined provide complete system façade monitoring. piezoelectric generator (PEG), supercapacitor (SC), Power Conditioner Circuit (PCC), Optic Sensing (FOS) interrogator, IoT gateway transmitting measurement data within an Internet Things (IoT) platform. tailored address challenges related integrity envelopes. Results demonstrate potential stand-alone solution sector but raise issues certain limitations, requiring further investigation. In particular, emphasizes constraints energy production integration. It highlights necessity carefully consider limitations broader context their applicability, providing insights informed deployment harvesting technology envelope
