Keppel Infrastructure @ Changi is an example of sustainable architecture and landscape design. It is Singapore's first retrofitted building to achieve Green Mark Platinum Positive Energy rating.

Keppel Infrastructure @ Changi is a remarkable example of sustainable architecture and landscape design. It is Singapore's first retrofitted building to achieve Green Mark Platinum Positive Energy rating under the GM:2021 scheme, a testament to its commitment to sustainability.

One of the most striking features of the building's design is its vertical greenery, which covers close to 1000 square metres and is placed alongside vertical solar panels. This greenery not only enhances the biophilic design of the building but also reduces the surface and ambient temperatures of the building, mitigating the urban heat island effect and improving the energy efficiency of the solar panels.

One of the building’s main feature is its 910-square metres of vertical greenery being placed alongside vertical solar panels.

The integration of vertical greenery with other features such as highly efficient air-conditioning, smart sensors, LED lights, rainwater harvesting, mechanical ventilation systems as well as solar panels on the rooftop and building facade makes the positive energy rating possible. Over 20 species of plants were used for the green wall including a mix of climbers such as Philodendron scandens, ferns such as Nephrolepsis biserrata, and shrubs such as Tabernaemontana divaricata and Schefflera arboricola. The maintenance requirement for the plant is also an important consideration. Hence, given the height of the green wall, access pathways for Mobile Elevated Work Platforms (MEWPs) were catered for.

Rainwater harvesting together with automatic drip irrigation using rainwater and NEWater supports the growth of the vertical greenery and reduces the building’s water consumption. The use of sustainable design principles in the architecture and landscape design of Keppel Infrastructure @ Changi increases the long-term sustainability of the installation.

As the first building in Singapore to implement photovoltaic vertical panels together with extensive vertical green walls, Keppel’s innovative greening efforts will pave the way for more of such co-located installations around Singapore.
