The Lotus Building in Wujin, China

The building was also designed to minimise energy usage with over 2500 geothermal piles driven through the base of the artificial lake. The entire lake water mass and ground beneath is utilised to pre-cool during summer and pre-warm during the winter, the air conditioning systems that lie beneath the lake. The project is also naturally ventilated and utilises evaporative cooling from the lake surface to drive a thermal chimney within the main flower pod.
