| Door Type | |
| Applicability | All doors, required input |
|---|---|
| Definition | The baseline standards classify doors as either: swinging or non-swinging. Non-swinging are generally roll-up doors. The prescriptive U-factor requirements depend on the door type so this input affects the baseline building criteria. The door types are described in greater detail in the baseline standards and the associated User's Manuals. This building descriptor may be derived from other building descriptors, in which case a specific input is not necessary. |
| Units | List: swinging or non-swinging |
| Input Restrictions | The door type shall be consistent with the type of door represented on the construction documents or as-built drawings. |
| Baseline Rules | The baseline building door type shall be the same as the proposed design. |
| Door Geometry | |
| Applicability | All doors |
|---|---|
| Definition | Door geometry defines the position and dimensions of the door surface relative to its parent wall surface. The azimuth and tilt (if any) of the door is inherited from the parent surface. The position of the door within the parent surface is specified through X,Y coordinates. The size is specified as a height and width (all doors are generally assumed to be rectangular in shape). The details of how the geometry of doors is specified may vary for each energy simulation program. |
| Units | Data structure: opening |
| Input Restrictions | No restrictions, other than that the inputs shall agree with the construction documents or as-built drawings. |
| Baseline Rules | Door geometry in the baseline building is identical to the proposed design. |
| Door U-factor | |
| Applicability | All doors |
|---|---|
| Definition | The thermal transmittance of the door, including the frame. |
| Units | Btu/h•ft•°F |
| Input Restrictions | Door U-factors shall be taken from the default values in Appendix A of ASHRAE Standard 90.1-2001 or ASHRAE Standard 90.1-2007, or shall be obtained from NFRC test procedures. |
| Baseline Rules | The door U-factor in the baseline building depends on the baseline standard, the climate zone and the type of door (swinging or non-swinging). Use values from [bookref id="baseline-building-u-factor-criteria-for-doors"]. |
