The Sustainable Energy Floor (SEF) is a fully recyclable pedestrian floor system which can be used in pavements and high footfall areas, such as sport arenas, airports, railway stations, shopping malls, and office and apartment blocks. SEF enables people to generate their own energy to illuminate the space around them, or the energy can be used to power local systems such as street lights and signing systems. Energy Floors Smart Grid is Another option is to incorporate SEF in the Energy Floors Smart Grid. With this grid a self-sustained energy system can be created, to which other renewable energy sources can be added too. Any energy consuming products can be fed from the Energy Floors Smart Grid.
