[Bldg-sim] Addition, or Separate Building?

[David Eldridge]

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.

Subject: [Bldg-sim] Addition, or Separate Building?

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
