| Summary: | 碩士 === 淡江大學 === 建築學系 === 88 === It is very important to develop guidelines for the effective use of daylight in architectural spaces and to computationally predict the distribution of daylight in interiors of buildings, detailed data on the availability of daylight in general, and the illuminance distribution of the sky. Based on statistic criteria such as correlation and relative error, comparison of between measured and predicted. This study includes the following contents：
Chap. 1 To point out the research motive、subjects、method and procedure.The daylight measurement station at the Tamkang University of Taipei was upgraded from a general class station.
Chap. 2 To organize and sort out the domestic and abroad''s research and specific achievements from related articles collection in order to clarify the connections between correlation research subjects and establish the research orientation and scope.
Chap.3 To discuss the point for attention about the solar radiation predicted model . Using the linear equation between solar radiation and duration of sunshine that was founded by Prescott in 1940 to regress the equation of solar radiation and duration of sunshine of Tan-Shui area.
Qg/Qa = 0.1902+5.894（n/N）
Chap.4 In the part of "quantifying diffuse daylight",via the special designed experiment,I use the relative position between sun and nine illuminators,and trigonometric function of solid geometry to find the direct and diffuse daylight.
The model of clean sky： Ed-cr = 37.063（sin At）0.682
The model of partly-cloudy sky：Ed-pc = 0.28 + 45.219（sin At）1.0187
The model of clean sky：Ed-cd = 0.28 + 45.219（sin At）1.0187
The comparison based on statistic criteria of correlation showed,for this specific study,that the IES-CPC,Tseng,Wen-Kai (1999) models were evaluated.
Chap.5 Base on NBC & NOAA ''s condition of sky , I short out the data of "solar radiation" and "quantifying diffuse daylight". There are three conditions: clear sky ,partly-cloudy sky, and cloudy sky. Also I make use of two-dimesion and three-dimesion regressive equations to deduce the dynamic model of diffuse daylight.
Chap.6 To provide building designers with daylighting performance data and design guideline for architectural space. Through the finest examples from the beginning of modernism to the present,this compendium examines the way natural light is captured,and shaped in architectural space.
Chap.7 To provide a reasonable predict model and the applied and the legitimation and the research scope of achievement on the research. Besides, suggest a specific stucture for further study.
According to the measurement of solar radiation and availability diffuse daylight and the quotation of theoretical model, provided the result of regional model that we can refer in architectural design.
