Rugby World Cup venue Verifying heat countermeasures Kumagaya August 6, 14:50, known for being the hottest in Japan

One of the venues for the Rugby World Cup to be held next month, in Kumagaya City, Saitama Prefecture, which is known for the hottest heat in Japan, the heat countermeasures around the venue have been completed, and verification of the effect has begun.

Kumagaya City, Saitama Prefecture, which is the venue for the Rugby World Cup, was last year's highest observation point at 41 degrees and 1 minute, and national and prefectural research institutes examined heat measures around the venue. I have advanced.

As a result, measures were taken such as pavement pavement with the effect of reflecting infrared rays and blocking heat on the outdoor passage where the audience moves, and planting trees in a zigzag so as to increase the shaded space. So we decided to verify the effect.

From this month, prefectures began to observe 10 items such as temperature, humidity, and solar radiation at three locations in the venue.
In the verification, when the temperature of the ground surface was examined, it was found that the temperature was lowered by about 15 degrees at the place where the special pavement was performed, and it was found that the effect greatly exceeded the previous expectation of about 9 degrees. It was.

In the future, prefectures etc. will analyze the data obtained from observations and compile the verification results before the World Cup.

Researcher Masayuki Hara of the International Center for Prefectural Environmental Sciences said, “We are surprised to see more data than expected even on this day's observations. Talking.
