Openstudio standards - Whole Buildings

Looking for advice on how to use openstudio-standards for space types that do not have the Whole building option.

Some building types (Office for example) have an option for whole building when determining the space_type_ratios from the building_type. However, most do not have it.

I am coding a very simplifided model for a hospital and this is one of the buildling types that do have the whole building type unfortunately. I can understand why of course. Hospitals are complicated.

I am considering two potential approaches:

  1. Use a different standard like NECB (I am using ASHRAE 2013 at the moment) as these seems to have the whole building option for hospital.
  2. Use blend_space_types_from_floor_area_ratio and blend_internal_loads from OsLib_ModelSimplification

The latter seems to be the approach in some of the measures

Any recommendation?

If you blend loads in a hospital, you are going to get high internal loads from MRI rooms getting exhausted with the high ventilation rates coming from the operating rooms. I think you are better off assuming space type ratios for the different kinds of space types and not trying to blend them together.

Good point. Thanks
