Combined Condensation Resistance and U-factor Calculations

Software/Versions Affected:

• THERM›6
• THERM›7

Before simulating a file that has the Condensation Model activated (ie, there are red boundary conditions inside the glazing system), go to the Options menu, Preferences menu choice, THERM File Options tab and make sure the checkbox labeled "Use CI Model for Glazing Systems" is checked. In some instances, even though the glazing system was imported with the Condensation Resistance model turned on, and there are red boundary conditions in the glazing system cavity, the "Use CI Model for Glazing Systems" box will NOT be checked in the Options/Preferences/THERM File Options tab. This will be fixed in future versions so that this step is not necessary.
