<p class="MsoNormal">Actually, by mistake courtyard is modeled as interior opening (however, it should be modeled as exposed to atmosphere and walls should be exterior walls), so, equest considered them as adiabatic walls by default, but as per the drawings
we have glazing on these walls, even we model glazing to adiabatic walls, the energy consumption is not getting changed, so the issue is, how to model both U value and SHGC implications in the model?<o:p></o:p></p>
