Energetics with the Conservatories
Comprising two glass biomes, the Conservatories copy the cool-dry climate with the Mediterranean and semi-arid sub-tropical regions as well as the cool-moist climate with the Tropical Montane location. They house a diverse assortment of plants that aren't commonly seen in this perhaps the world and are of high efficiency value.
The conservatories really are a statement in ecological engineering and employ a suite regarding cutting-edge technologies with regard to energy-efficient solutions within cooling. This suite of technologies may help achieve at very least 30% savings within energy consumption, in comparison to conventional cooling technological know-how.
1) Minimising Photovoltaic Heat Gain
The two conservatories are equipped with specially selected glass that allows optimal light set for plants, but reduces a large amount of heat. The roof is fitted with a sensor-operated retractable sails in which opens automatically to offer shade to the actual plants when this gets too very hot.
2) Cooling merely the occupied areas
The Conservatories employ the strategy regarding cooling only the reduced levels, thus reducing the degree of air to be cooled. This is achieved through thermal stratification – ground cooling by refrigerated water pipes cast within the floor slabs permitting cool air to be in at the reduced occupied zone as the warm air rises and is also vented out at high levels.
3) De-humidifying the oxygen before cooling
To reduce how much energy required from the cooling process, the oxygen in the Flower Dome is de-humidified by liquid desiccant (drying agent) before it can be cooled. This desiccant is recycled using the waste heat in the burning of the actual biomass.
4) Creating energy and harnessing spend heat
Electricity is generated on-site to perform the chillers in which cool the Conservatories. At the same time, waste heat is captured at the same time to regenerate the actual liquid desiccant. This co-generation of energy is achieved through a Combined Warm Power (CHP) steam turbine that is fed by horticultural waste in the Gardens and different parks around Singapore. This reduces dependency for the electrical grid.
