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.
The Flower Dome, spanning 1.2 hectares and 45 metres in height, replicates the cool-dry climate of the Mediterranean and semi-arid subtropical regions such as South Africa, Madagascar, Western Australia and the Mediterranean Basin.
The Dome is fitted with 3,332 glass panels of varying shapes and sizes. Spectrally-selective glass and light sensor-operated shadings help to minimize solar heat gain while allowing maximum light for plants.
Spectrally selective glass coatings filter out 40 percent to 70 percent of the heat normally transmitted through insulated window glass or glazing, so lesser heat will pass through.
