According to the report taken from the Garden by the Bay website, the concept of Gardens by the Bay are the principles of environmental sustainability.There are two main lakes within the garden lake system: Dragonfly lake and Kingfisher lake. These two lakes act as a natural filtration system as well as a provider of aquatic habitats for the diversity of biological life living within them. Water run-off from within the Gardens is captured by the lake system and cleansed by aquatic plants before being discharged into the reservoir. Naturally treated water used in the built in irrigation system from the Gardens.  It raises awareness of the value of aquatic plants in nature, and highlights the significance of clean water in sustaining biodiversity. This is only achievable by incorporating the following methods - firstly by the filtering of water, reducing nutrient load and maintaining an aquatic ecosystem. Hence the conservatories replicate the cool-dry climate of the Mediterranean and semi-arid sub-tropical regions and the cool-moist climate of the Tropical Montane region. By applying the cutting-edge technologies for energy-efficient solutions in cooling, it can help to achieve at least 30% savings in energy consumption compared to conventional cooling technologies. This allows for reduced energy consumption, minimizing solar heat gain, cooling only the occupied zones and de-humidifying the air before cooling and generating energy and harnessing waste heat. Therefore , with the use of photovoltaic cells on the supertrees the solar energy harvested will be used for the lighting of the supertrees while others are incorporated within the conservatories acting as air exhaust containment units.
