Daylighting system adds natural daylight, occupant comfort and energy-savings. The dome design creates diffused lighting throughout the day without hotspots, reducing electric lighting costs by up to 70% when combined with lighting controls.

In the cold winter, when accumulated snow on roofs comes into contact with cold eaves during thawing, icicles are easily formed and severely endanger the personal safety of occupants and pedestrians, and downspouts are consequently frozen or blocked to result in potential hazards such as overflow of snow melt and even bursting and falling of downspouts.
