摘 要：Road tunnels consume a large amount of energy,especially in the Canadian cold climate,where the roads are heated electrically or deicing during the *** a more sustainable and resilient road tunnel energy system,we conducted an exploratory study on installing a semi-transparent photovoltaic(STPV)canopy at the entrances and exits of a tunnel under a *** proposed system generates solar-powered electricity,improves thermal and visual conditions,and reduces energy *** this study,field measurements of road surface temperature and air temperature were conducted,and numerical simulations with and without STPV were performed to study air and road surface temperatures under different traffic *** field measurements show the road surface temperatures are higher than the air temperature on *** interior air and road surface temperature were measured to be above 0°C,even though the outdoor temperature is far below 0°C,thus significantly reducing the need for deicing in winter using *** simulations show that the air and surface temperatures elevate due to the solar transmission heat through the STPV canopy,thus reducing deicing energy consumption *** fire safety analysis also showed that the proposed system s top opening should be located near the tunnel entrance instead of the canopy entrance for better smoke exhaust during a fire.
