National Research Project on Kaze-no-michi for City Planning: Creation of Ventilation Paths for Cool Sea Breezes in Tokyo

A national research project on ventilation paths is introduced as one effort to mitigate urban heat island (UHI) effects. This project is intended to establish a scientific background to promote effective UHI countermeasures suitable for the characteristics of each region. We focused on the ventilation paths of sea breezes, the effects of which had not yet been sufficiently and scientifically investigated. We conducted a large-scale measurement campaign, numerical simulations using a supercomputer, and wind-tunnel tests in order to develop assessment techniques that can be used to quantitatively predict the effectiveness of creating ventilation paths for sea breezes to achieve an enhanced sea breeze for urban design.
