In Niigata City, a climate of the winter is characterized by very strong wind and a lot of snow. There is a possibility of a wind environment induced discomfort even with a low rise building in this area. It is difficult to use the current criteria in such cases because of the difference in consciousness of a resident and the frequency of the wind speed. Therefore, it is very important that new criteria which can be adapted the climate at a northwest area of Japan. The purpose of this study is to develope the new criteria for Niigata City by the wind tunnel experiment, the field survey and the questionnaire. The results are as follows, (1) By the questionnaire survey of the wind strength, the conscious of the wind strength will be begun when to put up an umbrella is difficulty, and discomfort break out when a walk is a difficulty. (2) The criteria of the wind environment in Niigata area is laxer than the acceptable frequency of Murakami's criteria. As for this criteria, the acceptable days per annum that is the maximum gust wind speed exceeds lOm/s per a day of the 1.5m height is 102 days, and 15m/s is 21 days, over 20m/s is 4 days.
