As a passive cooling strategy, natural ventilation is an energy conservation technology with great developing potential. The typical technologies of natural ventilation include night ventilation and natural ventilation with heat storing materials. The factors which affect ventilation include technique parameter, climate parameter and building’s parameter. The natural ventilation in summer in a typical building in Changsha City, which locates in hot summer and cold winter area, was measured. The effects of air exchanging rate, ventilation time, the area of exterior windows and the indoor heat storing mass for the ventilation are analyzed and validated by simulation.
