Energy-Saving Assessment Method Based on Matter-Element Model for Highway Tunnel Illumination Technology

Over the past decade, with the rapid growth of tunnel percentage in China's Midwestern highway construction, the tunnel operation cost rise quickly. In the cost, energy consumption of tunnel ventilation and illumination occupies a great proportion. For the purpose of realizing energy-saving and emission-reduction, there have been some new illumination technologies, for instance, the new type lighting lamp, the improved lamps installation arrangement method, and some new illumination control technologies. However, after a few new technologies were applied, the phenomenon of energy-saving but not money-saving appeared. For the scientific and objective evaluation of highway tunnel illumination technology energy-saving effect, construct evaluation index system from the three dimensions of technology usability, economy, and the application effect, and then evaluate the energy-saving effect based on matter-element model. The result of assessment will give decision support for the later selection of highway tunnel illumination technology proposal.
