@edpmay - Have you tried Thermal Bridging & Derating (or TBD), an OpenStudio Measure? It’s been used recently by other LBT users. It works off of an OpenStudio model (.osm), but will work with an .idf (although additional steps are required). It offers what you’ve expressed (“approximate the impact of linear construction thermal bridges on Zone energy consumption”), but it is limited to what @MichaelDonn identifies as the smearing approach (simply because that’s what most energy codes/standards require). We hope to extend TBD towards automating the generation of surface “slivers” (an alternative approach, described more clearly in ASHRAE 90.1 2022 - look up Table 11.5.1, under “5. Building Envelope”). This alternative is preferable with contrasting transient effects (between e.g. mass wall and linear thermal bridge), or for localized surface temperature assessments (e.g. condensation). But other than that, TBD should handle what you’re after. Do let us know if you’ve come across any issues with TBD; we’re keen on improving it (when we have time).
EDIT: Re-reading, noticed I wasn’t really answering your question. We had initially considered OtherEquipment + EMS (instead of the surface “sliver” approach). The former fell out of favour as it would be of little help to assess localized surface temperatures and condensation, for instance.
