Thermal environments inside the continuous covered walkways located in Southeast Asia under the tropical climate were investigated on field observations in summer 1996, and evaluated by calculating SET^* and equivalent temperature of radiation. Solar radiation influenced thermal environment inside the continuous covered walkways. In daytime, SET^* inside the continuous covered walkways was lower than outside, however the evaluation for SET^* did not show comfortable environments. In nighttime, the situation was reversed. Curve of shadow for horizontal surface showed that at Taipei the continuous covered walkways shade direct solar radiation, however at Singapore does not shade.
