| Abstract: | A model for evaluating the light environment based on tunnel life cycle theory was established to achieve energy savings and low carbon emissions in tunnel construction. The construction and operation periods during the entire life cycle of the tunnel were investigated. The objective function was established using the design parameters of the tunnel light environment. The objective function integrates calculations of carbon emissions and costs based on different preference weights, which are critical parts of the evaluation model. A multidimensional evaluation model of the highway tunnel life cycle was developed based on the objective function and safety constraints. The proposed model was used to develop a calculation program for carbon emissions in a tunnel light environment. A visual chart was plotted based on the operation time. The analysis results were output, and the parameterized calculation process was achieved. Finally, considering the light environment design scheme as a case study, an evaluation model was employed to compare and select five schemes. The carbon emissions of each scheme over the entire life cycle were computed and analyzed based on the cost and carbon emissions. The results show that the cost of the all-day operation mode is 33% higher than that of the half-day operation mode on average and up to 1.5 times that of the half-day operation mode. The operating time significantly influences the life-cycle cost of the optical environment. The calculation results indicate that the total carbon emissions during the construction and operation periods and lighting power consumption contribute to the significant carbon emissions throughout the life cycle of the tunnel, and therefore, become the major carbon emission source during the life cycle of the light environment. This study is valuable for optimizing the design of lighting systems. The green advantage can play a leading role in a light environment design to achieve carbon neutrality. Green innovation and environment-oriented process advantages can significantly influence the entire life cycle evaluation of the scheme, which is one of the leading directions in achieving carbon neutrality in tunnel engineering. |
