[Equest-users] Simplified Method Glass Conductance Entry

[Carol Gardner]

Riley,

If the over all U value and SC reported at the end of the LV-D report for
each exposure match yours, I wouldn't worry about it. When you are looking
at each window you are probably seeing some sort of adjustment for area.
