The Oasis in the City, Central Park Is a New Indicator

Taichung Central Park follows three core concepts of the smart city and plays a decisive role
in the low carbon aspect. Based on the landforms in the park, five detention ponds with a total
capacity of 180,755 tons were planned. Four of them were designed by drying methods to
be wetlands, which means they are used to be public spaces without torrential rain and when
torrential rain occurs, the rainwater can penetrate the underground layer, supplement the
underground water, reduce the downstream drainage pressure and flooding rate, and further
implement the spirit of “Sponge City.” The park is expected to be self-sufficient in energy
supply, so Park 138 and Park 51 are installed with solar panels to provide power for lighting,
buildings, climate devices, parking lot maintenance, etc., hoping to be an ecological park of
energy saving and carbon reduction. The water recycling system is also installed in the park and
the water resources plant is built to offer the recycled water for the sprinkler system and toilet
flushing in the entire park. The sprinkler system is also connected with the rain sensors so that
every single drop of water can be used at the right time. In planting design, as many indigenous
species (about over 1,600 arbors) are conserved as possible, and 8,921 arbors, including Maples,
Beeches, Camphor trees, Formosan nato trees, Phoebes species, Chinese pistache trees and
Ring-cupped oaks, are newly planted; these 10,000-strong trees are set to be a green lung for
Taichung City and form a forest park. Finally, all the hardware facilities in the park, from the
longest suspension bridge, visitor center, 12 VR experience space to smart citizen kit, make the
space full of fun and surprises and let the citizens experience new technologies and points of
view while visiting the park.
