对苏北沿海地区传统民居及新民居的夏季室内热环境进行了实测对比研究，发现传统民居全天室内温度波动幅度比新民居小，热稳定性更好。通过对二者壁面温度的分析发现，传统民居围护结构具有更好的热稳定性。传统民居室内空气温度纵向有分层，屋顶处空气温度比1．5 m 处高2．4℃。传统民居由于单面开窗，夏季室内通风不畅，全天室内风速不足0．1 m／s，夜间室内风速仅为0．01 m／s。运用 Fanger 提出的 PMV-PPD 修正模型对室内热环境舒适度进行了预测分析，发现传统民居夏季室内舒适度较差，全天室内 PMVe 计算值均在0．85以上。

Through contrasting the indoor thermal environment in the traditional dwelling with the new built dwelling in coastal North Jiangsu in summer,finds that the indoor temperature fluctuation of the traditional one is less than that of the new in all day,and the thermal stability is better.Compares the wall temperature in the traditional dwelling with that in the new built dwelling,finds that the thermal stability of the envelope in the traditional dwelling is better.The indoor temperature has the characteristics of vertical stratification in the traditional dwelling.The indoor temperature near the roof is 2.4 ℃ higher than that at 1.5 meters.Only one-side opened window leads to weak ventilation effect in the traditional dwelling.The indoor ventilation velocity is less than 0.1 m/s in all day and it is only 0.01 m/s at night.By using modified PMV-PPD model to predict the thermal comfort,finds that the indoor thermal comfort is worse in the traditional dwelling and the PMVe is above 0.85.
