Why do I get an error when I click on "Check Compliance?"


When clicking “check compliance” the program displays an error message that “REScheck could not complete performance alternative calculations.  Review input and edit as necessary.” 


The problem most likely relates to the basement walls you have specified. The DOE-2 simulation program used in REScheck for performance alternative calculations sometimes generates this error even though the entries appear valid.

As a workaround, we recommend that you split your basement walls so that for each basement wall you add a new above-grade wall to represent the above-grade area of the basement wall.
