5 · 4.2.1.1 and 5 4.2.1.2 require that U-factors and solar heat gain coefficients (SHGC) be determined for the overall fenestration product (including the sash and frame) in accordance with ISO 15099. The building envelope trade-off option in $ 4.3.5 requires the use of visible light transmittance (VLT):
