LINNÉ creates multifunctional urban infrastructures for cities, developers, and campuses, like the Candélarbre smart lamppost (FR patent). It uses vegetated architecture and BIONOCTA blue-free light (worldwide patent) to cool heat islands, restore biodiversity, and cut light pollution. Sustainability is achieved through durable, repairable materials, social manufacturing in France (ESAT partners), and low-impact use (smart dimming).
