这项研究估计了日光照度，并对其在配备可移动百叶窗系统的办公室中的有效性进行了分类。首先，使用 DIALux 进行测量以验证和应用仿真模型。其次，利用与案例办公室相似的物理特性构建了模拟模型。第三，仿真模型提供了可移动百叶窗系统板条角度的采光计算。后来使用 Mamdani 模糊推理系统采用了模糊模型。在该模型中，四个输入，即小时、角度、距离和位置被模糊化。通过实施模糊规则成功地估计了特定点的日光照度，预测能力达到 87%。为了测试办公室内日光照度的分布，根据采光标准和设计规范，该模型构建了均匀度的有效性等级。对于可移动百叶窗系统，30°和45°的板条角度在整个标准工作时间内比其他角度提供更均匀的日光分布。因此，根据模拟模型与模糊模型的匹配程度，模糊模型的一致性结果大部分与模拟结果完全吻合。由于模糊模型成功地估计了日光照度及其分布（均匀性），因此可以轻松地用于检查早期的建筑设计方案。
This study estimated daylight illuminance and classified its effectiveness in an office with a movable blind system. First, measurements were carried out to validate and apply a simulation model using DIALux. Second, the simulation model was constructed utilizing physical properties similar to those of the case office. Third, the simulation model provided the daylighting calculations in terms of the slat angles of the movable blind system. A fuzzy model was later employed using the Mamdani fuzzy inference system. Four inputs, namely, hour, angle, distance and location, were fuzzified in this model. The daylight illuminance at specific points was successfully estimated by implementing fuzzy rules, resulting in a prediction power of 87%. To test the distribution of daylight illuminance inside the office, effectiveness classes of uniformity were constructed by this model in accordance with daylighting standards and design norms. Regarding the movable blind system, slat angles of 30° and 45° provided more uniformly distributed daylight than other angles throughout standard working hours. Thus, according to the degree of match between the simulated and fuzzy models, the majority of the uniformity outcomes of the fuzzy model fully fit the simulation outcomes. Because the fuzzy model successfully estimated the daylight illuminance and its distribution (uniformity), it could be easily employed to examine early architectural design schemes.
