Sustainable Urban Regeneration through Noise Mitigation and Energy Self-Sufficiency: The Ascoli Piceno PVNB Model

Photovoltaic Noise Barriers (PVNB) provide an innovative approach to reducing noise pollution and generating renewable energy along major roadways. Implemented worldwide, PVNBs combine noise mitigation with solar power production, improving the acoustic environment and supporting sustainable energy targets. They enable energy communities through local energy generation and use, fostering independence from central power grids. PVNBs exemplify community-led sustainability, boosting public engagement in renewable energy initiatives. Recent research shows PVNBs lower noise levels significantly while generating electricity without losing acoustic effectiveness. Various designs, like top-mounted, cassette, and zigzag configurations, offer distinct advantages in energy yield and sound reduction. PVNBs produce noise shadows similar to traditional solid barriers while generating considerable renewable energy. The Ascoli Piceno project in Italy, spanning 350 meters, is a key study focused on optimizing both noise reduction and energy generation. This case highlights practical deployment, considering local conditions and infrastructure integration, and demonstrates PVNBs as an effective multi-purpose urban solution for environmental and energy challenges.
