The results show that the periods when the maximum outdoor temperatures are higher than 24 ℃ are suitable for night ventilation, the corresponding length is about 60 days, taking 72.3 percent of the summer cooling season. When the air conditioning system is used in Harbin, this night ventilation system would of...
