High-tech devices make holiday travel more comfortable

6. Smart skylights

Smart skylights at Xiamen North Railway Station in Xiamen, Fujian province, can be easily controlled by monitoring light intensity, wind force, precipitation, and indoor-outdoor differences in real time, in a bid to improve the indoor environment and save energy.

"With smart skylights, the ventilation system stops operation for 40 days per year, equivalent to a reduction of 14.13 tons of carbon dioxide," said Sun Yufeng, deputy head of Xiamen North Railway Station.
