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.
