When buildings receive damage by the natural disaster in general in Japan, the Japanese damage potential scale (complete destruction and partial destruction) is performed to the damage. This standard of the high wind damage is also applied as it is as for the seismic damage and the flood damage, etc. However, the majority of high wind damage of buildings is damage of the exterior material, and it is thought that the grasp of the situation of the high wind damage is difficult in Japanese damage potential scale. Then, it proposed the new damage potential scale limited to the high wind damage, and the utility was confirmed to be applied to the last year's typhoon damage.
