Green tech flourishing at Gardens by the Bay

Singapore's latest icon--a superpark spanning over 100 hectares--features energy efficiency technologies which save up to 30 percent in electricity costs and generates up to 8 percent of own power needs.

There are more than a quarter of a million rare plants in Singapore's latest icon Gardens by the Bay--a superpark that covers more than 100 hectares, which threw open its doors to the public in June after being conceptualized six years ago.

The attractions include the world's largest green house, which comprises two domes that replicate environments from cooler and dryer climates.

Behind the scenes, a number of sustainabilty innovations have been incorporated into the design, making the gardens a showcase of energy efficiency technologies.

Some of the features include specially selected glass panels that minimize solar heat gain, and a cooling process that dehumidifies the air using a liquid dessicant system to save on energy, said Richard Pang, assistant director of facilities at Gardens by the Bay, adding these energy-efficiency technologies result in up to 30 percent of electricity savings. 

The garden's dependency on the power grid is also reduced through the use of solar panels installed on some of its tower-like Supertree structures. Together with a biomass power generator, the gardens generates up to 8 percent of its electricity needs.
