Chapter 4 -Optical performance analysis
Then, considering the glassblock as a double glass with reference to UNI EN 410: g = 31,25 % 43 Light transmittance - The results of the simula3ons on the Hyp. 3a are presented by way of informa3on. Table 4.33 shows the values of total transmi4ance (τ) absorptance of the glassblock (αgb), absorptance of the DSC (αdsc) and total absorptance (αTOT), total reflectance (ρ) registered at 12 different wavelengths. The results of the complete simula3on, considering the combina3on of the weights assigned at each wavelength are shown in Table 4.34. λ (nm)
