摘　　要：本文对世博国家电网馆半室外空间进行了被动式环境控制设计，采用建筑自遮阳、风压强化自然通风、太阳烟囱热压自然通风、细水雾降温组合的方案，以改善参观人员的舒适度。使用CFD模拟、多区域网络法和能量平衡法计算了建筑风压贯穿通风、太阳烟囱热压通风和细水雾降温的效果。选取当前通用的基于舒适标准和安全标准的室外热舒适评价模型SET和WBGT，对舒适度改善的效果进行了评估。研究结果表明，采用被动式环境控制设计后，世博会期间统计（典型年气象参数）不满足舒适（SET〉30℃）小时数从901（20％）降至154（3％），不满足安全（WBGT〉32℃）小时数从203（5％）降至10（0％）。In this paper, the semi - outdoor environment of the state grid pavilion was controlled by using several passive environmental control technologies to improve visitors＇ thermal comfort. The technologies were including building self - shading, wind pressure ventilation, solar chimney （ thermal pressure ventilation ） , and spraying cooling. The effect of using these technologies was estimated using CFD simulation, muhi -zone network method, and energy balance method. Based on the calculating results, the improvement of thermal comfort was evaluated by using SET and WBGT indexes, the general standards for outdoor thermal comfort estimation in the view of comfort and safety. The results showed that when the passive environmental control technologies were applied, the uncomfortable hours （SET 〉 30℃ ） during the expo （typical meteorological year） were decreased from 901 （20%） to 153 （3%） , and the unsafe hours （WBGT 〉32℃） were also decreased from 203 （5%） to 10 （0%）.
