HIGH PERFORMANCE LIGHTING - ON THE ROAD FOR …

savings. The goal of this paper is to provide insight in how the road tunnel design phase and the tunnel lighting design itself: maximize the energy efficiency of tunnel lighting, thus minimize (electric) energy use. Note that the impact of the choices in these design stages are mostly irreversible. Hence, it is of utmost importance to carefully take decisions in each stage.

Use of sunlight in road tunnels: An approach to the ...

Coupled systems heliostats-light-pipes allow real energy savings in the lighting installation of road tunnels. (2) Partial solutions for the use of sunlight in tunnels like light-pipes, can remarkably improve their performance with heliostats due to the parallel injection of light, even when the sun position could never allow the use of light by light-pipes alone.
