BEOpt: No energy used for water heating for certain time periods

Hello,

I am modelling a multi unit townhouse right now and have noticed that in the hourly output view, some months have a drop that isn't present in other homes that I have modelled for the same weather file. It drops down to 0 btu at some points which doesn't make sense. I have changed the water heater type, floorplan, and checked between single-family detached vs multi-family. I am using a small city within California as my weather file that I got from https://climate.onebuilding.org/, and I compared it to Los Angeles, and the trend is still there. Does anyone have any suggestion on why this could be the case? Thanks

Can you provide your BEopt project file via Google Drive or Dropbox? And maybe provide a screenshot?

BEopt 2.8 assumes there are several vacation periods throughout the year, per the Building America House Simulation Protocols: May 26-28, Aug 12-18, and Dec 22-25.

I agree that it's pretty confusing. Vacation periods have been removed by default for the upcoming BEopt v3.
