Optical Data Library (number-sign)5 for use with the WINDOW 4.1 computer program including NFRC certified data

摘要

This report contains additional data for 783 glazing products that can be used with the Window 4.1 energy analysis program. The NFRC requires that all simulations must be carried out using NFRC-certified optical data only. Solar heat gain coefficient and visible transmittance must be calculated using spectral transmittance and reflectance in the solar range. U-factor calculations must use spectral or integrated emittance. NFRC-certified data within the Window 4.1 program is indicated.
