Convective heat transfer coefficlents fbr calm conditions were evaluated f ｛)r each part of the clothed human body ， and compared to those of 中 e nude bod) J ． This was done f-) r both standing and sitting postures ， using a heated therma 【 manikin ， Clothing surface temperatures were measured with an inf 士 ared imaging radiemeter ． The convective heat transfer coefficients were larger for the clothed ma 通 kin than f｛)r the nude manikin ， both f｛)r the whole body and f () r the individual body parts， Large differences were observed in the head， the pelvic region ， the chest ， and the back． 「 This resulted in 40 to 50 ％ increases of convective heat transfer coeC5cients fbr the whole body． Regressbn models for convection heat transfer under ca 】 m condition were presented for use in thermophysiological modeling ． Clothing insu 】 ations were also evaluated and compared between three methods ， The results demonstrate that three methods of estimating clothing ｛ nsulatlon can produce slgnificant ［ y different resu ］ ts、 Keywords ' (／ ' onvective heat tran ． gfer ． clothing insutation， 1召かα 一 red thermography ． human body， thermal con 言 ／-) rt ， natural con りection
