Problems occuring simulating energy demand

[Mar-Ges]

The project of Issue #3469 now produces some other problems. Unfortunatly, I still cannot see the database in GUI. I can simulate solar radiation as well as occupancy. Problems occur simulating the energys demand:

Hi @Mar-Ges

This is a known/expected error. We have included the solution to this error in the last CEA Newsletter. If you are using a CEA file that worked for older CEA versions, you need to make the following updates on your database to make it work for CEA v.3.35.0 or later.

• Nagivate to CEA File > technology > assemblies > HVAC.xlsx > Tab HOT_WATER;
• Add the Column ['class_dhw'] with values = NONE, LOW_TEMP, MEDIUM_TEMP, or HIGH_TEMP, then save;
• Execute CEA demand.

Please also pay attention to the soon to be commited German DE Database. Thank you!

Regards, Zhongming

Perfect! Thanks a lot :)
