  • The Cloud Forest Conservatory, stretching 0.8 hectares, greets visitors with a 35-metre mountain and a 30-metre waterfall. The area replicates the Tropical Montane climate such as Mount Kinabalu in Sabah, Malaysia, and the higher regions of South America.

    There are nine zones of biodiversity and ecology from different parts of the world within the conservatory itself. Some include the "Lost World" which features plants found at 2,000 meters above sea levels, and "Crystal Mountain" which resembles caves within a mountain.

  • At the top of the man-made mountain, hydraulic sprays are fitted around to keep the temperature between 23 to 25 degrees, to imitate the climatic state of 2,000 metres above sea levels.

  • 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.
