[Bldg-sim] Addition, or Separate Building?

[Nick Caton]

I agree completely.

Let the scope/purpose of your modeling efforts decide whether modeling both building as one model is going to be beneficial.

>From my experience, the extra work entailed in properly setting up a representative "campus" plan may well be less work than just modeling both buildings, and if in the course of your studies you intend to address efficiency measures applied/unique to both buildings, I expect it will be more efficient and simpler to work within a unified project.

Best regards,

90.1 is flexible to model only one building or as a combined building, the determinant is what the client's purpose is in deciding to have an energy model project completed.

You could obviously model the whole complex with the specific central plant equipment, or else a single building could be modeled using district energy sources for heating and cooling depending on what the goal was for the study.

Hello Group,

I am modeling an existing building which could be seen as two buildings connected by a short hallway.  The quick story on this facility is that there were two buildings which were connected by hallways at some point, and are now on the same chilled and hot water systems. I'm having trouble finding a clear definition in 90.1 which tells me whether I should be modeling this as one building or two with a shared energy plant.  This is not a LEED project; I am only interested in a 90.1 interpretation.

Does anyone know of any clarifications, interpretations, or past experience which could help guide me?

Thanks,
Christian
