Radiation environment over the watered pavement and the highly reflective pavement, which have been developed for mitigation of the heat island phenomenon, were compared with that over a paved asphalt and natural turf under the same meteorological condition. Possible absorptions of long- and shortwave radiation by a supposed globe placed at 50cm above these surfaces were calculated. It is found that the highly reflective pavement had a potential to degrade the thermal environment over it due to the increase of reflected solar radiation, while the watered pavement did not have such a side effect. Human thermal environment can be improved more effectively by shading and/or selection of the color of clothes than by changing the types of pavements. The estimated SET^* on the watered pavement showed its superiority over that on the highly reflective pavement from the standpoint of the thermal comfortability at lower leg level.
