4. Parameters influencing photometric and energy characteristics
4.1 Glazing wavelength and tint
Figure 5 shows the comparative transmissions over the entire solar spectrum of clear glass and bronze glass of the same thickness.
The integrated transmittance values of these two glasses over the solar spectrum are given in table 12 .
