本研究は室内空間における姿勢の違いが体感温度に及ぼす影響を明確にするために行われた.床からの熱伝導による熱量を把握するために床面と人体との問の接触面積が計測された.姿勢は立位と椅座位, 正座位, 立て膝位, 胡座位, 側臥位が用いられた.正座位は立て膝位や胡座位, 側臥位と比較して接触面積が小さく, 立位や椅座位と同程度の接触面積であることが明らかとなった.熱放射による伝達熱量の把握のために人体の有効放射面積と人体と矩形面との間の形態係数が実測された.姿勢は正座位が用いられた.正座位人体の有効放射面積率は裸体人体で0.66, 着衣人体で0.70が得られた.正座位人体と矩形面との間の形態係数が図表化された.正座位人体と床面との間の形態係数値は立位や椅座位と比較して著しく大きな値となることが明らかとなった.実生活空間の温熱環境が実測された.体感温度指標には修正有効温度ETVが用いられた.姿勢と体感温度との関係が明確にされた.This study was conducted to investigate the influence of posture on sensible temperature. The contacted surface areas between the floor and the human body were measured to quantitatively determine the heat conduction from the floor to subjects. Six postures were used for the measurements: standing, sedentary, sitting upright, sitting with legs crossed, sitting with knees drawn up, and lateral decubitus. Under the sitting upright posture, the contacted surface area was smaller than under the sitting with legs crossed, sitting with knees drawn up, and lateral decubitus postures, and it was almost the same as the contacted areas under the standing and sedentary postures. The contacted surface area of the sitting upright posture was almost negligible compared with the total surface area. The effective radiation area and configuration factors between the human body and rectangular planes were measured to make a quantitative thermal radiation. The sitting upright posture was used to measure the effective radiation area between the human body and numerous rectangular planes and thereby determine a quantitative thermal radiation value. The effective radiation area factor was found to be 0.66 for a sitting upright nude subject and 0.70 for a sitting upright clothed subject. Diagrams of the configuration factors between the human body and the rectangular planes were represented. Configuration factors between sitting upright subjects and the floor were found to be significantly larger than those for standing or sedentary subjects. The indoor climate of a house was used, and the thermal environmental index calculated on each posture from the result of measurements. The modified effective temperature (ETV) was used for calculating the thermal environmental index. A clear, qualitative correlation was evident between posture and sensible temperature.
