A Proposal of the Environmental Map of metropolitan Area in Japan and Simulation for Improvement

通过两年的研究，将研究内容总结如下：1)在名古屋的环保建筑中进行了现场测量。评价了公园植物、水塘对玻璃屋顶的影响以及地下场所的雾冷却效果。2)通过测量，对酒井某办公楼自然通风与吊扇送风混合空调的性能进行了研究。此外，还进行了模拟分析，以阐明自然通风对温度条件的影响。3)通过六本木初中的长期和短期测量，评价了屋顶绿化对城市气候的热效应。提出了屋顶绿化热模拟的参数。4)通过模拟分析，评估极端天气对空间热环境和暖通空调设备负荷的影响。5)介绍了日本设计天气图。利用1981 ~ 2000年20年的天气记录，提出了日本800个地点的几种供热和制冷设计天气数据集。对东京、大阪和名古屋的城市大气进行了三维模拟，分析了地表条件和排气热对热岛现象的影响。从建筑的角度探讨了城市环境的改善策略。

The contents of study through two years were summarized as the following.1) Field measurement was performed in an environment-conscious building in Nagoya. Effects of plants in the park, a water pond on the glass-roof and mist cooling in the underground place were evaluated.2) Performance of hybrid air-conditioning with natural ventilation and air-circulation by ceiling fans were investigated in an office building in Sakai through measurement. In addition, simulation analysis were done in order to clarify the effects of natural ventilation dependent on the temperature conditions.3) Thermal effects of rooftop greening to urban climate were evaluated through long-term and short-term measurement in Roppongi Junior High School. The parameters for thermal simulation of rooftop greening were presented.4) Simulation analysis were performed to evaluate the effects of extreme weather on space thermal environment and HVAC equipment load.5) Design weather maps of Japan were presented. Several types of heating and cooling design weather data sets for 800 locations in Japan were proposed using weather records for 20 years from 1981 to 2000.5) Three-dimensional simulation of urban atmosphere were performed for Tokyo, Osaka and Nagoya and thecharacteristics of heat island phenomena affected by ground surface condition and exhaust heat were analyzed.The improvement strategy for urban environment were investigated from an architectural wide viewpoint.
