In order to research thermal environment in the heights of middle and high buildings, the observations of vertical air temperature were carried out at 10 points in Nagano City for over one year. The authors obtained the following results; (1) In summer, high-rise air temperature are higher in daytime and lower in nighttime than that near the ground. (2) H-L (vertical difference of temperature) is larger in daytime than nighttime. (3) H-L in daytime is large on sunny days in early and high summer. (4) Sky view factor and H-L have a negative correlation in daytime. Therefore, in areas dense with buildings, difference between temperature near the ground and that high above the ground in daytime. Temperature in the heights of middle and high buildings differ from that near the ground, particularly in hot seasons and daytime.
