According to the article “Sustainability in the gardens” taken from the Garden by the Bay website, it mentions the effort done in ensuring that it is environmentally sustainable in terms of water and energy. The author talks about the implementation in Dragonfly lake and Kingfisher lake, how it acts as a natural filtration system as well as a provider of aquatic habitats for the diversity of biological life living within them. Mentioning about it being naturally cleanse before discharged into the reservoir for irrigation in the Gardens. Claiming that it will raise awareness of the value that aquatic plants play in nature and also highlighting the significance of clean water in a sustaining biodiversity. By incorporating different methods in achieving the results, in which the author describes. The author also brought up that with the use of technologies, it raises the energy-efficiency in cooling by at least 30% savings in energy consumption. Describing how the conservatives’ uses shade to lower the heat within reducing the need of cooling. How in return the waste heat produced by the electricity could be reuse for dehumidifying. Author mention about the use of photovoltaic cells on the supertrees harvested which will be used for lightings while others act as air exhaust containment units. I believe Garden by the bay uses an eco-friendly approach in being energy efficient and sustainable at the same time.
Firstly by looking at the artificial supertrees, the solar energy collected in the day are used at night for lighting purposes and water technology within the conservatories below. (Lauren, 2015) This removes the dependency on electricity, making it energy-efficient in sustaining itself. Showing how harvested energy is put to good use without affecting the plantation around. With more than 162,900 plants involving over 200 species, the diversity it adds is immersing. (Supertree grove) Considering the sustainability of the supertress, plants are picked not only based on their rarity and high visual appeal, it needs to be suitable for vertical planting while requiring little to no maintenance. This shows that the supertrees are built with the concept of being self-sustaining. While serving as a structure for the plants to grow on, it acts as an exhaust pipe for the underground biomass boilers. (Blain, 2014) With the clever design of supertrees combining both plants and air exhaust in one, it beatifies the garden without compromising the need of having an air exhaust.
Lastly, with a canopy that shapes like an inverted umbrella, it provides shade for visitors around the garden. Reducing the heat felt in the garden providing a better sightseeing experience for visitors. Eliminating the need of having shelters around the garden, which prove to be less useful compared to the supertrees. It also collects rainwater distributing it to all parts of the garden for irrigation or places that demands water. (Blain, 2014) This in return cuts the cost of managing the gardens due to the reduced usage of water. Although the amount of water that obtained is not consistent, it is still part of the ecofriendly approach done by the garden.
In conclusion, the authors write about the different ways in which sustainability and energy efficiency implemented in different parts of the garden without compromising the ecosystem. I agree with the sustainable efforts that the author mention in the article and that each decision made has taken into account of energy efficiency and sustainability.
