拟议研究的主要目的是提出一个经过验证的综合计算程序，用于预测垂直（或倾斜）窗口上的晴空太阳光谱，作为北美当地气候条件的函数。它将与现代开窗分析软件结合使用，以动态评估任何开窗系统（尤其是具有高度光谱选择性的开窗系统）的峰值光学特性，作为窗几何、时间和当地气候的函数。本程序针对具有辐射传输或大气科学中等背景的工程师，因此试图协调准确性、灵活性和易用性。

The main objective of the proposed research is to propose a validated and integrated calculation procedure for the prediction of clear-sky solar spectra incident on vertical (or otherwise tilted) windows as a function of local climatic conditions in North America. It is to be used in conjunction with modern fenestration analysis software to dynamically evaluate the peakload optical characteristics of any fenestration system (particularly those that are highly spectrally selective), as a function of window geometry, time, and local climate.This procedure is aimed at engineers with modest background in radiative transfer or atmospheric sciences, and therefore attempts to reconcile accuracy, flexibility, and ease of use.
