The Update Glazing button also allows Users to add Fritting to glazing that is selected. This is to simulate a pattern on the glass which will reduce Solar Heat Gain and Daylight. When a window has been selected in the Details List of the Façade Manager, the Update Glazing button may be used to apply fritting if you wish. Fritting may be applied to both windows and curtain walls.
There are options in the Fritting settings for Transparency % and Coverage %. When these are applied, a new parameter is added in ‘Edit Type’ in Revit to indicate the values chosen for each option. As these are modified, these will be updated.
The results on the Dashboard will also update as fritting is applied. The solar heat gain and daylight indicators should reduce as more fritting is applied. The more transparent the fritting is, the less effect it will have on reducing Solar Heat Gain. The less transparent the fritting, the more effective it will be on reducing Heat Gain. Coverage will work proportionally – the higher coverage %, the more it will reduce Solar Heat Gain.
Note: If Transparency is 100% or Coverage is 0%, fritting will have no effect. Also, when you apply fritting to one instance of a glass type, it will be propagated to all instances of that type in the model (as is the normally the case in Revit).
This will create a new family type for that chosen instance of glazing in Revit since you may not wish to apply a universal change to all instances in the model. You will see the fritting setting in the Properties Palette in Type Properties under Type Comments. This setting could then be exported to a schedule to review which glazing has simulated fritting applied. This is not written to the model but is saved by FenestraPro and used to adjust the calculations.
When the window selected has no thermal properties set in Revit (Analytical Construction Properties are set to None), you may use the Linc drop-down list to select a Glass Type or type in values directly.
When the window has properties already set in Revit, only the Linc drop-down list is available.
Custom values may be input here where the available values in Revit are not suitable and where the user would like to use alternate values or use data from actual product specifications.
