  • A liquid desiccant system is used to achieve greater energy savings in the cooling process. It first de-humidifies the air with a liquid desiccant, then cools the dry air. This reduces the need to over-cool the air to remove its moisture as in a conventional air-conditioning system.

  • The 18 Supertrees in the Gardens were modelled and constructed after the form and function of mature trees. They create height to balance the current and future tall developments in the Marina Bay Sands area.

    Some of them are embedded with photovoltaic cells to generate solar energy so they can light up at night. Others will be integrated with the Cooled Conservatories and serve as air exhaust receptacles.

  • The Supertree has four major parts: the reinforcement concrete core with an inner vertical structure that upholds the Supertree; the trunk which has a steel frame attached around the reinforcement concrete core; planting panels which are installed on the trunk in preparation for the planting of the living skin; and the canopy.

    Shaped like an inverted umbrella, the canopy is assembled and hoisted through a hydraulic jack system, with the exception of the 50 metres Supertree canopy which will be assembled at its final height.
