Unenclosed and Unconditioned Spaces
ASHRAE 90.1-2019 PRM Reference Manual¶ ↑
Space types such as ventilated parking garage, attics, and crawlspaces are defined by Standard
90.1-2019 as unenclosed spaces, and for the purposes of envelope requirements, envelope components adjacent to them are treated as exterior surfaces.
Implementation¶ ↑
Key Ruby Methods¶ ↑
Existing¶ ↑
-
model_apply_standard_constructions
: this method applies the standard construction to each surface in the model, based on the construction type currently assigned; code was added to handle surfaces adjacent to another space: if the space is conditioned, then the surface should be handled just like an exterior surface and be assigned the baseline constructionsNew¶ ↑

model_apply_constructions
: generic method used to call the PRM and non-PRM specificmodel_apply_standard_constructions()
