Hotel Indigo Changi Airport will open a new 255-room hotel at Singapore’s Changi Airport Terminal 2 by 2028. The hotel aims to be the first zero-energy hotel in Singapore and potentially the first zero-energy airport hotel globally, incorporating sustainable features like solar panels, hybrid cooling systems, naturally ventilated corridors, and rainwater-harvesting technology. Located in the public area of Terminal 2 and connected via a linkway, the hotel will enhance Changi’s hospitality offerings.
