This research, based on a study of direct solar radiation and 30° inclined horizontal shading devices used in architectural solar radiation shelters in Taiwan’s major cities on a northern latitude of 22N-25N through 48 vertical orientations, assesses the effect of direct solar radiation and 30° inclined horizontal shading devices in the performance of interior shading coefficients for architecture in these cities, with the aim of discovering a correlation between most direct solar radiation and best horizontal shading devices in Taiwan’s major cities. This research proposes that various cities’ solar rays are directly related to the radiating capacity only and camouflages radiating capacity. The solar emissions at various latitudes depend directly on the radiating capacity theoretical value again to carry on the discussion. The results of this study will provide energy conservation guidelines for different orientations to meet the needs of designer’s intension in the future. This study includes the following content： Chap1. The presentation of Discuss research motivation, subjects, objects, methodology, limitations, hypothesis and scope. Chap2. The analysis is arranged to the weather data in Taiwan area, above analysis according to various cities’ monthly mean temperature determination warming up period and cold cool seasonal cropping following chapter analysis definition. Needle The visor incline 30° angle visor facility inspects its condition to this object of study level outside. Chap3. To analyze the 48 Vertical Orientations and month the Direct Solar Radiation in Danshui（Other 12 cities please refer to the appendix）,to proposed that the urban 48 facings sun goes directly to radiating Capacity it Relates and establishes the data. Chap4. To analyze the 48 Vertical Orientations and month the solar radiation shelter in Danshui（Other 12 cities please refer to the appendix）, to proposed that the urban 48 position sun goes directly to radiating capacity it Relates and establishes the data. Chap5. To analyze the 48 Direct Solar Radiation and Solar Radiation Shelter in Danshui（Other 12 cities please refer to the appendix） the efficiency of combined models. Chap6. To analyze 48 Vertical Orientations the performance data of Direct Solar Radiation and Solar Radiation Shelter in the Taiwan. So as to proposed that various urban sun goes directly to the radiating capacity only and camouflages radiating capacity it only Relations. Depends on various latitudes sun to go directly to the radiating capacity theoretical value again to carry on the discussion Chap7. To make conclusions and the recommendation of study.
