[Equest-users] eQUEST building skin effects in cooling but not heating

[Brian Davis]

I am using the refrigeration version of equest 3.61 and have several zones within the building which have exterior walls and roof.  The equest output notes loads in cooling for them but not in heating while other zones properly indicate loads for both cooling and heating, has anyone else run across this and can suggest something for me to check.  The output is listed below.
