Behind the scenes: Changi Airport green walls 

Sinagpore Changi Airport Terminal 4 exterior green wall

Singapore’s Changi Airport is known for its lush greenery, which includes a variety of green walls. These walls are made up of vertical gardens that are designed to improve the aesthetics of the airport while also providing environmental benefits.

The maintenance cost of these green walls is a topic of interest for businesses looking to incorporate similar features into their own buildings. 

Changi Airport green wall: Terminal 3

Changi Airport currently has several green walls, including one of the largest indoor green walls in the world in Terminal 3. Consisting of 10,000 plants and 25 species, the vertical garden designed by Tierra Design is over 4,100m2. Making it nine times the average block size in Brisbane (460m2).  

The cost of installing a green wall can vary greatly depending on the size and complexity of the project. On average, the cost of installing a green wall in Australia can range from $300 to well over $1500 per square meter. Therefore the cost of maintaining a green wall is also an important consideration for businesses. Green wall maintenance at Changi Airport is estimated to be around $50 to $100 per square meter per year. This cost includes watering, fertilising, pruning, and replacing plants as needed. 

Green walls maintenance is carried out by a team of technicians who are trained in the care of these systems. The number of technicians required will depend on the size and complexity of the green wall, but a typical team will consist of two to three people. 

Changi Airport green wall: Jewel shopping centre

The crown in Changi’s “crown jewel” is the nature-themed airport shopping mall the “Jewel”. It encapsulates Singapore’s commitment to sustainable urban development and ambition to seamlessly blend nature and modernity.  

Despite the initial cost and ongoing maintenance expenses, green walls can provide significant benefits for businesses. They can improve indoor air quality, reduce energy costs, and enhance the overall aesthetic of a building. Additionally, green walls can also boost the reputation of a business as being environmentally friendly. For these reasons, green walls should be seen as a long-term investment and not a short term one. 

Overall, the maintenance cost of green walls at Singapore’s Changi Airport is relatively low, averaging around $50 to $100 per square meter per year. Australian businesses should consider the potential benefits and costs of maintenance when making their decision. Particularly because labour costs in Australia are considerably higher than those in Singapore, which does not have a national minimum wage.
