Highway Tunnel Ventilation Technology Energy-saving Assessment Based on Matter-element Model

In recent years, with the rapid increase of tunnel percentage in Midwestern highway construction, the tunnel operation cost rise quickly. In the cost, energy consumption of tunnel ventilation and illumination occupies a great proportion. In order to realize energy-saving and emission-reduction, there have been some new ventilation technology, for instance, the improved ventilation device, the improved ventilation method, and some new ventilation control technology. However after some new technology was applied, the phenomenon of energy-saving but not money-saving appeared. For the scientific and objective evaluation of highway tunnel ventilation technology energy-saving effect, construct evaluation index system from the three dimensions of technology usability, economy, and 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 ventilation technology proposal.
