I am studding the effect of window glazing on space cooling and heat
rejection. In this regard I have taken various types glasses having
different U value and SHGC value and with the help of e-Quest it is clearly
seen that for each case there is a sufficient change in space cooling and
heat rejection. Now being a research student it is vary important to know
that how e-Quest calculate the same. Though which equations e-Quest
calculate the space cooling and heat rejection. Please let me know as soon
as possible.
Thank you

Hope this helps.
