Sendai Oasis – 1000 Rain Gardens, Tohoku University, Japan wins the Smart Cities Award at the Dutch Archtitecture Biënnale in Rotterdam.
According to the Netherlands Architecture Institute: “this project examines alternatives for the design of the city of Sendai, Japan, following the effects of the earthquake and tsunami in March 2011. In order to protect residents against extreme temperatures (heat islands) and from the effects of heavy rainfall, the Tohoku University proposes a network of small ‘rain gardens’. This network will provide a sustainable solution for water recycling and create green public spaces in the city. The jury was very impressed by the completeness of this plan, the whole seems to have a significantly larger impact than its individual parts.”
The Tohoku University which has been immediately rebuilt after the earthquake has a testgarden at the faculty terrain. According to the website of Sendai Oasis: “Creating a Sustainable City based on its Water System, Aobayama Rain Garden (ARG) proposes a multi-environmental control device that originally functions for the recovery of rain water, Infiltration areas and groundwater replenishment, thus acting as an effective environmental device linking the Keywords of Low-carbon society, Heat Island control, Energy recycling, Bio-diversity and Disaster aid spot with Emergency water supply. BY using ITC networks, real time monitoring is possible for all the data such as storage water levels, wind velocity related to thermal comfort index and green energy consumption degree via smart meters.”
