热岛现象和城市热环境退化是日本面临的严重问题。虽然针对热环境提出了各种缓解措施，但根据不同的城市形态，其效果是不同的。对于适当的城市设计，有必要从数量上了解这些措施的效果。为此，本文以东京大町地区为高层办公楼，Kyobashi区为中层办公楼，分别进行了对流、辐射和传导的数值模拟，比较了热释放点和空调方式、绿化、地表高反照率、交通量等措施的影响。结果表明，Otemach采用高反照率材料、地面和道路绿化等措施是有效的，而在Kyobashi，空调的散热点和方式对其影响很大。
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.
