If more than one reference solar system is being used, then nd the “aperture area
weighted” SSF for the combination. Determine each individual reference system SSF using
the total aperture area LCR, then take the “area weighted” average of the individual SSFs.
The LCR method allows no variation from the 94 reference passive designs. To treat
off-reference designs, sensitivity curves have been produced that illustrate the effect on
SSF of changing one or two design variables. These curves are presented in Figure 9.10 for
three “representative” cities, chosen for ...
