9.1.3 Detailed Model

3 minutesread

Preferences may be set here to:

1. Automatic reload when document changes.

This will ensure that changes to the Revit model are automatically detected and the results will update without needing to use the Refresh button.

Note: This will remove the Refresh button from the Dashboard and each time that changes are made, the results will automatically begin to recalculate.

On larger models, performance can be improved by unchecking this.  Unchecking this will disable dynamic updates to the Revit Energy Model and restore the Refresh button to the Dashboard. This option allows you to make several modifications and when complete, you may use the Refresh button on the Dashboard to update the results to include all changes.

Option to remove manual Refresh for Detailed Models


2. Read Shade Surfaces

This option will include energy analysis surfaces that are identified as ‘Shade’ surfaces when the Spatial Elements option is used (for models with rooms and spaces). Sometimes External Walls may be classified as Shade Surfaces if certain conditions exist eg. there is a parapet behind an element, there are freestanding walls or where there is no room or space adjacent to these elements etc.

Shade Surfaces are normally not included since they are not subject to heat loss or gain.

Include reading of Shade Surfaces if required

3. Do not show surfaces smaller than

A setting for reading small surfaces is also provided.  Setting this to an appropriate value will prevent small areas such as service ducts, janitor’s closets etc from being given a separate Surface by FenestraPro when using the Spatial Elements option.

Note: this will cause differences in results when selecting all Surfaces in the list as opposed to selecting no Surfaces.


Setting which Surface Areas to include in the analysis


4. Read cached U-Factor, SHGC and VLT values from Glazing App

This option may be used to ensure that values set in the Glazing application for nested panels are imported into FenestraPro for Revit.  These values will be used when calculating results for curtain panels with multiple sub-panels and materials.

Turn on reading of the settings made in the Glazing Tool


5. Openings Host Tolerance

This option will only be displayed when using Building Elements mode. This setting will help where model elements are in close proximity to glazing such as structural columns close to windows, or where windows are close to the corner of a building etc.

If this is the case, all elements may not be included in the list when Building Elements is chosen as the analysis method. For example, some windows may not be counted.  Adjusting the tolerance here may help in this situation.

When using the Building Elements option, set openings tolerance if required to improve accuracy
