The purpose of this study is to make clear the relationship between Land Use Zoning and green coverage ratio in urbanized city. The subject area was selected in Sakai City, Osaka. The statistical difference of NVl between the low-floor area ratio and other parts, the low-building coverage ratio and other parts are clear. And NVl of each zone is under the influence of the distance from city center area to each zone. The results of this study show that there is the possibility to lead green area ratio in urbanized city by Land use Zoning.

The purpose of this study is to make clear the relation between Land Use Zoning Regulations and Green Coverage Ratio in Japanese urbanized city. It is probable that Land Use Zoning Regulations has an influence on Green Coverage Ratio for its restrictions to building form and use. However, this relation is not clear. For creating and protecting green area in urbanized city, it is important to consider the influence brought by land use zones. The study area was selected in Sakai City, Osaka, Japan. Green Coverage Ratios of past 3 terms in the study area were estimated by satellite remote sensing data (LANDSAT5-TM data), and its changes were analyzed statistically using GIS. The results of this study show that there are some tendencies of Estimated Green Coverage Ratio's change in each land use zones. And this means the possibility to take control of Green Coverage Ratio in urbanized city and give supports to the establishment of the green area-related laws by Land Use Zoning Regulations. © 2003, Architectural Institute of Japan.

The aim of this study is to estimate distribution of meteorological factors in high resolution in order to thermally evaluate a land use in urban area. In this study, distributions of monthly mean average, maximum and minium air temperature were estimated by using 3 layered back propagation neural network system. The input data sets for this neural network system were (1) height above sea level, (2) normalized vegetation index, which was calculated by using LANDSAT TM data and (3) distance from seashore. The supervised data set for learning were meteorological data observed at 30 stations around the Osaka Bay. R^2 value and the sum total of error show a sufficient accuracy of this method with neural network system in comparison with the estimating method with multiple regression, which we have used before. The addition of distance from sea shore was recognized to improve an accuracy an estimation of air temperature both in sea side area and in inland area. After checking the over learning problem on the neural network system, distribution of monthly mean minimum air temperature around the Osaka Bay was drawn by this method.

In summer daytime, air temperature under the large green canopy is lower than its surroundings. We call this space "Cool Spot". Some sets of meteorological elements were measured in and around urban parks in Osaka in August 1992 to clear thermal effects of green canopy. The correlation between the cool spot effect and the length of green canopies, wind speed, the ground surface temperature and eddy diffusivity were examined. Finally a simple model was proposed to predict the cool spot effect.

This study is a part of investigations, which is concerned with urban heat island research in Okinawa. In order to clarify the ventilation system of a traditional house in Japan, which is supposed effective to cool the severe summer thermal conditions, we were subjected to measurement of indoor climate in summer at the national important cultural property Nakamura House in Okinawa (built in 18c.). We measured wind speeds and directions at eight points in the attic and seven points on the ground floor of the house, using the three dimensional sonic anemometer. As the result, large amount of air exchange between the ground floor and attic space under the roof, which causes mitigate the thermal environment in the attic. We also carried out numerical simulations to evaluate the several openings in the roof and effect of heat in the furnace.

・地中深さ5cmの年較差で正規化した各深さ別地中温年較差と地表からの深さの関係は指数関数とよく似たグラフとなった。（Figure 5，6） ・５ｍまで月別地中温度が一定の地層は見られなかった。つまり不易層は見られなかった。・月別平均地中温度と同気温との差をFigure 2しめした。地表面から約50cmまでの深さまでは年平均気温と概ね同じ温度であったが、100cmより深くなると変化があらわれはじめ、 −500cmでは、月別年平均気温と月別年平均地中温度との差が大きいところで±15℃程度あり、温度差エネルギーの取得への期待が高いことが確認できた。・降水量と地中温度との関係確認を試みたが、地中温度と明確な相関が確認できなかった。・地表面と深さ−500cmでは地中温度のピーク出現時約9ヶ月遅れることから都市ごとの解析が進めばピンポイントで深さ別でのピーク時差を利用することが可能となる可能性を示した。・以上の結果から、任意の深さにおける月別平均値中温度の推定ができる可能性を示した。

Realizing a low-carbon society is our urgent necessity. In order to achieve this goal, in our branch of architecture dealing with a way of using energy, challenges are required to convert to use the renewable resources. Our aim is to establish a simple and easy prediction method for architects to estimate a prospective amount of geothermal energy. We found a collection of underground temperatures archives, which is compiled by Ministry of Agriculture, Forestry and Fisheries (MAFF) and Japan Meteorological Agent (JMA) in 1982. With this database (recorded 1932-1948), we reexamined hypotheses about underground temperature. We confirmed the followings.- We could not find isothermal layer among 0 – 5 meters depth.- Underground temperature was the deeper, the smaller in annual variation.- The averages of underground temperature at each depth at each observatory were almost equal (average difference was 0.9 degrees).- The delays of peak temperature appearance at 5 meters depth in comparison with the surface layer were 3.3 months in average.- Average annual underground temperatures were higher than Average annual air temperatures (The differences was 1.7 degrees in average).

The purpose of our research is to evaluate roof tiles as cool roofs. In part1 of our articles, we inspected the physical properties of several kinds of Japanese roof tiles. In part2, we reexamine the Japanese roof tile production methods in order to produce ideal environment conscious roof tile.We manufactured several kinds of roof tiles by different methods and compared thermal performance of them by the following 2 ways.(1) We computed thermal conductivity and water absorption rate by a laboratory experiment. The roof tiles fired in lower temperature had smaller thermal conductivity and larger water absorption rate than the ones fired in higher temperature.(2) We measured surface temperature with mock-up in external environment. After rainfall, surface temperature of the roof tiles containing more air didn’t rise so much.As a result, the roof tiles manufactured by traditional methods tended to have better thermal performance than the ones by current methods.

Sea breeze is regarded as the decisive factor to improve summer thermal environment in coastal urban area in Japan. According to the result of previous researches with numerical simulations, a strong ascending air current blocks the inland penetration of the sea breeze. To mitigate urban environment with sea breeze, the information of ascending currents is really important. To visualize updrafts, I used images from satellites, which show distributions of cumulus that give information of ascending current locations. In the same satellite images, boundary line of cumulus clouds along a coast can be acquired. The frontline of cumulus is regarded as sea breeze front. By using data from meteorological observations, I conformed the relation between the cumulus boundary line and the sea breeze front, and patterns of the inland penetrations of the sea breeze in Osaka area. As the result of meteorological observations, the inland penetration of the sea breeze into the central east of Osaka delays in comparison with other area in Osaka. From the result of estimation with satellite data, mean land surface temperatures under the ascending current in the central east of Osaka is estimated to be higher than other area by around 20 degrees centigrade. The higher land surface temperature in the central east of Osaka helps accounts for the result of the delay of the inland penetration of sea breeze into this area. In conclusion, construction methods to keep land surface in lower temperature is very important to mitigate thermal conditions by using sea breezes.
