Summary & Reader Response: Sustainability Efforts (Draft 3)

According to the “Sustainability Efforts” (n.d.) webpage taken from Gardens by the Bay (GBTB) website, heavy emphasis has been placed on designing GBTB’s systems and technologies to achieve environmental sustainability. Firstly, GBTB uses their lake system to filter water naturally with aquatic plants. This system aims to promote the importance of clean water and how plants can play a significant role in our ecosystem. Environmental sustainability can also be achieved by conserving energy. GBTB uses specially chosen glass for their two conservatories to minimize heat gain, along with thermal stratification to reduce the volume of air that needs to be cooled. GBTB also generates their own energy with the “Combined Heat Power (CHP) steam turbine” and solar cells on the “Supertrees”. With these systems and technologies to reduce pollution and conserve energy, GBTB has proved that they are indeed upholding the environmental sustainability concept.
Environmental sustainability defines how we should be protecting our ecosystems and the sustainability of our natural resources (Mason, n.d.). Protecting our environment from any potential damage will be the key to this sustainability.

In my opinion, the lake system makes efficient use of the natural ecological processes. Instead of using other sophisticated technologies, GBTB choose to use reed beds and aquatic plants for the water cleaning process. Using reed bed in the lake system is environmentally friendly and requires minimal energy input (“Reed-Beds,”n.d.). In addition, the lake system provides the benefit of nutrients and pollution absorption by incorporating aquatic plants and reed beds. Nutrient pollution occurs when there is excess nitrogen and phosphorus in air and water (US Environmental Protection Agency [EPA], 2016). Too much of these two nutrients can lead to algal bloom, affecting the water quality. It may even cause serious impact on humans and the environment. This system has proven GBTB’s attempt to protect our ecosystem, following their main concept of environmental sustainability.

GBTB also came up with an energy-efficient solution by using the specially selected glass as the main material of the conservatories to reduce heat, and uses horticultural waste to generate electricity on-site for the cooling system. This reduces their dependency on natural resources, such as fossil fuels. Using CHP requires lesser fuel to produce energy, which will result in the decrease of greenhouse gases emissions other possible air pollution (EPA, 2016). Greenhouse gas is one of the main causes of global warming and the change in climate. Therefore, it is essential to reduce the emissions of greenhouse gases. By doing so, GBTB has shown efforts in environmental sustainability. 

Furthermore, the photovoltaic cells on “Supertrees” absorb radiation from the sun and convert the energy into usable electricity. The world’s natural resources are depleting, but solar energy will last as long as the sun rises. This makes it a good alternative to generate electricity. Furthermore, this way of creating electricity does not create pollution or result in global warming. With the “Supertrees”, GBTB attempts to protect the sustainability of the natural resources and our environment. This further proves that GBTB upholds the environmental sustainability concept.

To sum it up, GBTB follows closely to the environmental sustainability principles by ensuring that their systems and technologies help to reduce pollution and conserve energy. Although it is difficult to measure the effectiveness of those systems and technologies, GBTB has proven to put in a commendable amount of effort in protecting our ecosystems and environment.
