**2. Materials and Methods**

Commercial building energy simulation (BES) software does not consider WFG as a component of the heating and cooling systems. It is essential to provide building designers with a simple method to select the correct glazing and evaluate its performance at the beginning of the design stage. The first subsection defines three tested WFGs in terms of spectral properties. The second subsection shows the mathematical model that defined the dynamic thermal properties of the glazing. The third subsection describes the components and industrialization process of the unitized WFG.
