项目摘要

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.

本研究为期两年，主要研究内容如下：1）在名古屋的一座环保建筑物内进行了实地测量。对公园内植物、玻璃屋顶水池和地下室喷雾冷却的效果进行了评价。2）以日本坂井县某办公楼为研究对象，对自然通风与吊扇循环复合空调系统的性能进行了测试研究。此外，还进行了模拟分析，以明确温度条件对自然通风效果的影响。3）通过对六本木中学屋顶绿化的长期和短期测量，评价了屋顶绿化对城市气候的热效应。给出了屋顶绿化热模拟参数; 4）模拟分析了极端天气对空间热环境和暖通空调设备负荷的影响; 5）给出了日本设计气象图。利用1981 - 2000年20年的气象资料，提出了日本800个地区的几种类型的供热和制冷设计气象数据集。5）对东京进行了城市大气的三维模拟，以大坂、名古屋为例，分析了受地表条件和排气热影响的城市热岛现象的特点，探讨了城市环境的改善对策从建筑学的角度来看。
