Singapore's recently-opened Gardens by the Bay has a number of energy-efficient cooling as well as environmentally-friendly technologies. ZDNet Asia visits the park to understand the technology powering the cooling conservatories, Super Trees, and Dragonfly Lake.
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.
