已经开发了计算包含阴影的玻璃系统性能的计算方法，但尚未开发应用这些方法所需的测量标准和性能数据库。结果表明，在极大简化的假设下，这些方法可以用于计算任意玻璃系统的系统太阳光学特性和太阳热增益系数，同时需要有限的遮阳数据。给出了详细的计算公式，并定义了用于近似处理带阴影的简单嵌装玻璃的性能乘数。由于需要更高的精度，公式变得非常复杂。引文:研讨会论文，大西洋城，2002年

The computational methods for calculating the properties of glazing systems containing shading from the properties of their components have been developed, but the measurement standards and property databases necessary to apply them have not. It is shown that with a drastic simplifying assumption, these methods can be used to calculate system solar-optical properties and solar heat gain coefficients for arbitrary glazing systems, while requiring limited data about the shading. Detailed formulas are presented and performance multipliers are defined for the approximate treatment of simple glazings with shading. As higher accuracy is demanded, the formulas become very complicated.
