摘　　要：该文基于预测热感指数PMV值及计算机模拟技术,旨在提出一套适用于山东济南地区住宅建筑夏季节能因素的评价方法。选取山东济南地区的某一主卧室为研究对象,设定影响其室内热舒适的南向窗墙比、外墙传热系数、外窗传热系数三个主要因素,在节能规范范围内取值,通过CFD模拟和正交试验计算,得出其对住宅夏季室内热环境舒适度的影响程度。旨在有效地指导济南地区住宅的夏季节能设计。A thorough simulation study was conducted to investigate the effects of facades and wall-window ratio on the energy saving of residential buildings based on the concept of PMV in Ji＇nan. The results were then analyzed with Taguchi method. We found that the effect imposed by the wall-window ratio on the indoor thermal environment was more significant than the effect of facades. The results presented in this work may help in guiding the better design of the energyefficient buildings.
