Energy-harvesting structures

Definition

Energy-harvesting structures are architectural elements designed to capture and convert energy from environmental sources, such as solar, wind, and kinetic energy, into usable power. These innovative designs not only enhance the sustainability of buildings but also contribute to reducing the overall carbon footprint by integrating renewable energy solutions directly into the construction. By mimicking natural processes and leveraging biomimetic principles, these structures can improve energy efficiency and promote a more sustainable built environment.
