This paper presents a study about the integration of Piezoelectric Energy Harvesting Systems (PE-EHS) in building envelopes for powering Fiber Bragg Grating (FBG) sensors, enabling efficient and low-consumption monitoring with objective to leverage Structural Health Monitoring (SHM). The research includes preliminary tests conducted real environment validate PE-EHS when fully integrated into façade, capturing mechanical vibrations generated mainly by wind loads. Based on these activities, final configuration is defined provide complete system façade monitoring. Generator (PEG), Supercapacitor (SC), Power Conditioner Circuit (PCC), Fibre Optic Sensing (FOS) Interrogator, IoT Gateway trans-mitting measurement data within an Internet Things (IoT) platform. tailored address challenges related structural integrity envelopes. Results demonstrate potential stand-alone solution sector, but, raising 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 technology envelope
