项目摘要

Daylight should be used successfully to save the electric power consumed by the artificial lighting supplementary to the daylighting in daytime. Though the sky luminance distribution is essential for the prediction of daylighted environment, the Uniform Sky and the CIE Standard Overcast sky are not appropriate for the new energy saving daylight prediciton which were ordinarily applied for the daylighting estimation, because they shows only ideal or typical sky luminance distributions and not the approximation of the real sky condition.A new sky luminance distribution and a new daylighting calculation system are developed by this research work, and a microcomputer programme is flamed for the application of new daylighting calculation system and the estimation of electric power consumption by the supplementary artificial lighting in daytime. The new sky luminance distribution, i.e. Mean Sky shows a mean sky luminance distribution of a total working hours during a reference period at a reference point. It is composed based upon Average Skies by the probabilities of occurrence of the solar position, they are formed by the solar altitude from the three formulated sky luminance distribution, i.e. Clear Sky, Intermediate Sky and Overcast Sky and their probabilities of occurrence during total hours which are estimated from the mean relative sunshine duration.A set of equations needed in the composition of the Mean Sky have been proposed based upon the measurements data accumulated by the authors and standardized for their worldwide applications. The meteorological data from many points of the world, especially those concerned with the relative sunshine duration have been gathered and arranged for the composition of the Mean Sky there.It is great pleasure for the author that the fruits fo this research works are accepted by the CIE Technical Committee and approved as the main points of its technical report.

应成功使用日光，以节省白天的日光照射的人工照明所消耗的电力。尽管天空散热分布对于预测日光的环境至关重要，但均匀的天空和CIE标准的覆盖天空不适用于通常适用于日光照射估计的新的节能日光，因为它们仅显示理想或典型的天空亮度分布，而不是由新的天空散布和新的Sky Smirate System and Sky Smirtimation。燃料用于应用新的日光计算系统，并在白天通过补充人工照明估算电力消耗。新的天空亮度分布，即平均天空显示参考点的参考期间总工作时间的平均天空亮度分布。它是根据太阳位置出现的概率来基于平均天空组成的，它们是由太阳高度从三个配方的天空亮度分布（即晴朗的天空，中间的天空和过度的天空及其在总小时内发生的概率及其在平均相对持续时间估算的估计数据估计的估计的估计的估计的估计的衡量图的组成部分。针对其全球申请进行标准化。来自世界许多角度的气象数据，尤其是那些与相对阳光持续时间有关的人，并安排了那里的平均天空的构成。对于作者来说，这项研究作品的果实非常高兴，这项研究工作被CIE技术委员会接受并批准为其技术报告的主要要点。
