Changi International Airport – Terminal 3
Changi Airport is a key transportation hub in Southeast Asia and one of the busiest passenger and cargo airports in the world. Built to accommodate a surge in traffic, Terminal 3 is a steel-and-glass structure with four above-ground levels and a 9-hectare roof that spans ticketing, departure, and arrival areas.
One of the terminal’s most spectacular features is an overhead light modulation system that consists of glass skylights and thousands of aluminum louvers. During the day, the sensor-driven louvers limit the amount of direct sunlight entering the space by filling it with diffused light. At night, artificial light reflects off the louvers to provide a uniform pattern of illumination. This sophisticated technology helps minimize lighting and cooling costs while also adding aesthetic appeal
