1.Effect analysis of natural ventilation utilizing void spaces(1)Effects of natural ventilation are measured in an office building where spaces are ventilated by opening outside air inlets on every floor and outlets at the top of stairwell. It is found that air change rate due to natural ventilation is one to two cycles per hour through the measurement of concentration of the tracer gas as well as the measurement of air velocity and pressure difference at the outside air inlets.(2)Air movement through the measured whole building were simulated solving the equations of air flow rate balance. The air change rate due to natural ventilation with opening area of 2m^2 on every floor can be expected to be seven cycles per hour.2.Simulation of outside air flow rate coming into high-rise atrium buildingsAn estimation method of average effective opening area at entrance doors affected by number of persons passing through the doors is proposed and the relationships between entrance effective opening area and outside air rate coming through entrance in five atrium buildings are clarified through simulations.

1.（1）在办公楼中，通过在每层楼开设室外空气入口和在楼梯间顶部开设出口，对空间进行自然通风的效果进行了测量。通过对示踪气体浓度的测量以及对室外空气入口处风速和压差的测量，发现自然通风换气次数为1 ~ 2次/h。（2）通过求解风量平衡方程，模拟了被测建筑物内的气流运动。每层2m^2的自然通风换气次数可达7次/h。2.室外空气进入高风速区的模拟本文提出了一种受通过人数影响的中庭建筑入口平均有效开口面积的估算方法，并给出了入口有效开口面积与室外空气进入量的关系通过模拟，阐明了五个中庭建筑的入口。
