As Nanjing swelters under 40°C temperatures, an innovative "asymmetrical canopy" is keeping construction crews cool at a smart-industry research site. This high-tech shelter adapts to the pit's irregular shape, maintaining temperatures around 35°C - a lifesaver for outdoor workers.     The secret lies in its three smart modules: rope-driven panels, long-span rails, and curved segments that adjust to provide complete shade. Beyond comfort, the canopy improves air quality (cutting PM2.5 by 40% and PM10 by 70%) and reduces noise by 20%.     The site goes further with shaded rest areas, heat-relief supplies, and adjusted schedules - proving smart solutions can keep construction moving safely through summer's worst.
