when they include complex elements such as shading devices, which offer more precise control over when fenestration is shaded from solar gain than glass treatments.

Solar gain in opaque building components

Apart from windows, walls and roofs also serve as pathways for solar gain. In these components heat transfer is entirely due to absorptance, conduction, and re-radiation since all transmittance is blocked in opaque materials. The primary metric in opaque components is the Solar Reflectance Index which accounts for both solar
