Saving energy in road tunnels

With the Paris agreement, participating countries have expressed their ambition to limit the temperature increase of the globe to two degrees centigrade and, if possible, lower this limit to one-and-a-half degrees centigrade. In order to achieve this goal, our traffic infrastructure should become more sustainable by reducing the energy intake and using more sustainable energy sources. We have developed and researched the idea of using transparent PV-panels in daylight screens, which can yield an 80% energy reduction for the lighting of the entry zone, and thus 20% overall energy savings.
