7.2.3.1 Curtain Panels at an angle

4 minutesread
  1. Where the Curtain Panels are at an angle to the Curtain Wall, there is a slightly different workflow.

In this case, it is necessary to get the exposed surface area of the panel elements relative to the elevation. The Glazing App will not identify such surfaces without some input from the user.

It is necessary to add an extrusion to the panel family to represent the surface areas on a plane parallel to the Curtain Wall. ‘Edit Family’ may be used in Revit for this purpose.

  1. The lowest Panels may also have a Floor Surface which will need to be represented on the same plane. Creating surfaces parallel to the Curtain Wall plane will then be read and properties may be assigned and modified.

  1. For the new extrusions that represent the original panel surfaces, existing materials may be duplicated and a new name given to them ‘fpro…..’. This material will then be used by the Tool.

Once the panel is selected on the Model, the materials there will load in the Glazing Tool. Any materials which are picked up but are not relevant may be excluded eg. Edge of Sills which do not have a large enough surface to affect the results. Excluded materials are ignored (even if they have a value displayed).

Glazed Units may make use of the Glass Database to select a Glass Type with associated thermal properties.

Where R-values display in the dialog window but are not realistic, these may be edited (input a realistic value).

Set values for materials as normal, then use Refresh Zones to update.

You may check exposed areas of surfaces by going to an Elevation View in Revit and creating a region area. The area of this region may then be compared with the value in the Glazing Tool. You may override this value if required.

Sometimes the area displayed is the opening area within the panel grid instead of the actual material area and this will act as a check for angled panels. Zero % Frame value on the Dashboard may also indicate that an override is required.

When all materials have been set, select the Curtain Wall and click on the Populate Curtain Wall button.  This will then provide details on the area, percentage glazed, percentage frame and Overall U-factor. It will also load this curtain wall into the list for sending to the report with its Revit ID.

Clicking on the camera icon will export the data to CSV files. FenestraPro will then be able to read from this data to include in its calculations.

Once FenestraPro for Revit is launched, and the relevant Surface selected, the details of the panel properties will display in the Details List of the Facades tab.

Hovering over an item in the list will display the thermal properties from the cached values (saved in the report from the Glazing Tool).
