Abstract
The heat island phenomenon and urban thermal environmental degradation become serious problems in Japan. Although various relaxation measures for thermal environment have been proposed, the effects of them are different according to urban configuration. For proper urban design, it is necessary to understand quantitatively the effects of the measures. Therefore, in this paper, numerical simulations of convection, radiation and conduction were done in Otemachi area, as a high-rise office block, and in Kyobashi area, as a middle-rise office block in Tokyo, to compare the effects of the measures such as heat release point and way of air-conditioning, greening, high albedo of surface, and traffic volume. The result showed that the measures of high albedo material and greening on ground and road are effective in Otemach, and heat release point and way of air-conditioning affect very much in Kyobashi.
