Opaque Doors vs Doors with Glazing Vs Windows

Doors are modeled as doors and windows as windows. Doors with glass in them would be modeled with the glass in the door and either an overall assembly U-value or modeled separately as glazing and framing.

The impact would be related you your previous question on vertical glazing area and the 40% maximum. They define fenestration as not being opaque. So the glass in the doors counts as glazing area but a door is still a door.

Hi Marcus,    I am going to piggyback on the above question for  additional clarification on modeling HM doors on the perimeter of the building. The opaque doors are not labelled and therefore considering to use the following U-factor value from A7.1: "Insulated metal swinging doors, including fire-rated doors, insulated access hatches, and insulated smoke vents: 0.50" 1) Installer provided a certificate stating that with 1.75 inch thickness for the unlabelled HM doors with R-26 Rockwool insulation inserted under the hats and between the ribs of internal steel stiffeners, it's U-0.13. Is there any additional information should be asking them to support this claim, so I don't have to default to using the 0.50 U-factor per Appendix A7.1?    2) There is a variety of HM door types from Corridors leading to MECH rooms and bathroom, that I intend to model. These HM doors have features such as "kick plates  with louvers". Is it necessary to model these interior doors considering temperature differential in these spaces? Thank you in advance.  

U0.13 sounds like a point calcualtion. U0.5 sounds much more reasonable and realistic for an overall value. You don't need to model the interior doors, especially if the spaces are adiabatic and air just flows through them.
