I am running a school model in CBECC 2022 - it is an existing school with window retrofits so I selected Existing - Alterations. The software was able to complete the analysis but the results of energy use is all 0 - even interior lighting I assigned has no energy consumption results.
I realized when I selected Existing - Alterations in the Project interface, only DHW does not gray out. Can that be the potential issue?
When I run the idf in E+, I was able to get consumption results.
