The exterior walls we have designed for a school project are made up of vision glazing that is 58" tall and clerestory glazing that is 30" tall. Each (obviously) has a different area, and also different VLTs. Using the prescriptive method, I assume that I must figure the WFR to VLT values separately, and then add them together. For example, if I come up with WFR x VLT = 0.121 for the clerestory and WFR x VLT = 0.057 for the vision glazing, I must add 0.121 and 0.057 = 0.178 and thus potentially achieve this credit...? Thank you!

Hi Jill,
it is hard to me to determine without drawings whether the approach is suitable. The approach will depend on the location of the clerestory.
