This may happen if the previously saved Excel file is open on your desktop. Further saving of analysis results cannot be written to the same file if it is open.

Search for the open Excel file on your desktop and close this application, then try once again to save a Snapshot.

Version 4.2 identifies previous versions of the application and will manage the database files which are stored on your machine (previous Solar Load calculations, Custom Groups and Standards, and Log files etc). Once installed, Version 4.2 will rename older folders and save this data.

If an error message appears, try clearing the cache files in the FenestraPro folder. This contains folder contains previous data and calculations from projects which have been analysed. If the project has been modified or was previously viewed in a different version of FenestraPro, this database may need to be deleted to start afresh.

The folder may be found in this location on your machine:

C:Users\< User Name>\AppData\Local\FenestraPro.

All the files may be deleted here. New files will be created when FenestraPro is opened again in Revit.

Where the Add Windows function does not become available for a selected area on a model, this may be due to adjacent glazing being too close to the solid wall. Glazing that abuts a solid wall where windows are to be added, may prevent placement of windows there as the joint condition cannot be verified.

This may be overcome by moving the glazing away from the solid wall           (eg. 3 feet / 1 metre). This may also occur where internal glazed partitions abut a solid exterior wall – the Add Windows function may be disabled.

Open Building Manager and calculate the Solar Loads again .This will
populate the latest results for the model in its current state. Possibly,
the model was modified or there was an error contacting the web
server to get the solar data.
For Conceptual Mass Models – check that a glazing percentage has
been applied to the model. This may be done in FenestraPro’s
Performance Manager or in Revit’s Energy Settings.
For Conceptual Mass models – make sure that there is a glazing percentage assigned to the model in the Performance Manager. This can also be set in Revit’s Energy Settings.
It is a good idea to extend the panel to the side and leave open the
General Tab which will display any errors. You may check there to see if
there are any messages about your internet connection or issues with
the web server. A poor connection may not allow FenestraPro to
calculate the Solar Loads or display the Charts.
Also, please check that Glazing Properties have been set. When a
window or Curtain Wall has been selected, go to Edit Type in Revit and
check in the Analytical Constructions section for thermal properties. If
these are not present, choose a Glazing Type from the list in Revit or
use Linc to add a new type. (Note: new types assigned by Linc that are
not already present in Revit will not display in Revit until the Revit
Application is restarted).
Check that Revit’s Energy model is successful first and that there are
no warnings. If there are, try to resolve these first before opening the
application.
Make sure that you have not used Building Elements or Spatial
Elements options with a Mass model. These options are for use with
Detailed models only.
For Detailed Models, it is important that Properties have been set for
elements in the Revit model eg. that Walls, Floors and Roofs have
thermal properties. Glazing should be assigned a construction type also
with associated thermal properties for U-Value, SHGC (solar heat gain
coefficient) and VLT(visual light transmittance).
Walls that are external should have their function set to ‘External’ in
Revit. Walls that are set to Internal will not be excluded by FenestraPro.
This can often happen when a wall begins externally and continues
inside a building. If this is the case, a break should be made and
another Internal wall created internally to separate the elements.
Glazing material, if assigned, should have the required transparency
set in the materials browser, to be identified as glass.
Also make sure that the Energy Settings are correct. The Mode selected
should suit the model type eg. Conceptual Mass for Mass Models, use
Building Elements and Conceptual Mass for mixed models.
Also Ensure that the Phase is the same in the current Revit View and in
the Energy Settings.
Summary
  • Check the Phase is correctly set in the Energy Settings
  • Check the Mode is correct in the Energy Settings
  • Check that outside Walls have their function set to External and
not Internal
  • Any Glazing material should have a minimum transparency
  • Thermal Properties should be assigned to elements in the model (ie. Walls, floors, roofs, glazing)
  • For Mass Models, ensure that a percentage glazing is set
  • Check the internet connection is active and allows the web
service to send the results to your application
  • Try calculating the Solar Loads again in the Building Manager
  • If is still an issue, please contact us for support:

  • When installing FenestraPro, a screen will ask you to confirm permission to access Revit’s Construction Types file. If this is not checked during installation, the application will not be able to access this file to write the new entries.
  • If Revit’s Constructions.xml file is moved, replaced or edited manually after installation of FenestraPro, this may change the security permissions and prevent the application accessing the file. New Glass Types which are selected in Linc and are not currently listed in Revit will be added to the list, when Revit is closed and reopened. This allows the new entries to be written to Revit.

Check that the Revit View is not the Energy Model view. Rotation and highlighting functions are not compatible with this View. Change to a default 3D View in Revit to see highlights display and to use the rotation feature when selecting Facades or Surfaces.

Category: General

This means that there is a problem connecting to the internet. Please check your network connection and retry. FenestraPro requires an internet connection to calculate Solar Loads for the glazing. Different conditions will define the results (eg. Orientation/ Angle of Glazing, Climate, Occupancy etc).

This may occur if the Energy Model was created but then masses were modified/moved/deleted. The Analytical Surfaces may still be in the model but may be hidden. These can be removed by going to the Energy Settings and changing the Mode to another type eg. ‘ Use Conceptual Masses and Building Elements’ Apply this and then change it back if needed. This should clear the redundant surfaces.

Category: General

This happens if the setting in Options for including ‘Surfaces smaller than..’ is set to a higher value than is appropriate for the project. This setting will filter out Surfaces which have areas below this value. In some projects, these may add up significantly. Try setting this value to a lower figure or even zero.

Category: General

An error may occur if Linc is used to map properties glazing in the model which just been modified or deleted. If Add Windows or the Add Curtain Walls feature is used and then this is reversed (the glazing that was created is removed). Attempting to apply properties to this glazing in Linc may cause an error since the element no longer exists in the model.

This may also occur if properties have been applied to glazing which is subsequently deleted. This is not an error but simply a referencing issue where model elements are created or removed and dependent properties need to update. Users are advised to work methodically and allow the application to refresh and update as changes are made.

Category: General

This is due to the Energy Analytical Model (EAM) being recreated in Revit. While this is happening, it will prevent FenestraPro from updating. Please be patient while the Energy model recreates or go to the Analyse Tab in Revit and delete the Energy Model and Create a new one. You may also close and reopen FenestraPro which will initiate a new Energy Model.

If the model is changed substantially while FenestraPro is open (glazing is created or deleted or geometry is altered), you may need to go back to the Building Manager to Calculate Solar Loads again. In some cases it may be prudent to close FenestraPro and make the changes in Revit and then reopen FenestraPro to start afresh.

If there are multiple entries in Revit’s Constructions.xml list with the same name, Revit will use the entry which is last in the sequence. An entry which has the same name in the Linc database and is chosen for selection, may have a set of properties which do not match the entry in Revit.

This may occur where there are several entries in Revit for Glazing Types which have the same name eg. ¼” Double Glazing. Revit may have one entry with one set of properties, a second entry with another set of properties and a skylight entry with a different set of properties.

Revit invariably uses the last entry in the list which may be the skylight version. An entry chosen in Linc which appears to have the same name therefore, may not map to the correct Revit entry as there are multiple versions.

Users are therefore advised to check the thermal properties in Edit Type to confirm that the entry has mapped correctly.

Version 4.2 identifies previous versions of the application and will manage the database files which are stored on your machine (previous Solar Load calculations, Custom Groups and Standards, and Log files etc). Once installed, Version 4.2 will rename older folders and save this data.

If an error message appears, try clearing the cache files in the FenestraPro folder. This contains folder contains previous data and calculations from projects which have been analysed. If the project has been modified or was previously viewed in a different version of FenestraPro, this database may need to be deleted to start afresh.

All the files may be deleted here. New files will be created when FenestraPro is opened again in Revit.

  • If a colleague has the same version of FenestraPro, you may copy the results file and send it to them. If they paste this into their FenestraPro folder, the results will be available in the Charts and Dashboard when they open the application.
  • The path is C:/Users/‘Your User Name’/AppData/Local/FenestraPro
  • The file is called db which contains all the results recorded by the application.
  • FenestraPro should be closed down first as it will be accessing files in the FenestraPro folder. It is recommended that the person to whom you are sending the file, first close down FenestraPro if it is open and rename their existing database file as a backup eg. db should become – FProStore.db.bak.
  • This original file can then be restored later by:
  • Moving the new database file that you sent them to another folder outside the FenestraPro folder
  • Renaming the Original file back to the original name so that it will be used by the application.
  • The new file that you are sending them may then be placed in the Folder and will be used instead. It contains all the results for the models analysed to date. If they have access to the same models, this will be recognised and the results will appear in the application.
  • The version number of the software should be the same on both machines, otherwise there may be errors in reading the file or FenestraPro may fail to load.
  • The new file may then be stored elsewhere and the older file renamed back to its original name so that the user can continue their work.
  • Results may always be shared normally using the Snapshot Excel Report also which contains all the relevant information on the project.

Yes, FenestraPro saves your Standards in the FenestraPro folder which is on your local machine. This file may be copied and pasted into a colleagues folder on their machine if they also have a subscription to the application. First the colleague’s FenestraPro application should be closed out. Any existing file with Standards in their local folder should be cut and pasted to another location if it is to be restored later.

The sent file may be pasted into the FenestraPro folder and when the application is started, this will be used with the Standards that were created.

The path to the FenestraPro folder is usually on the C: drive and is found under Windows (C:) > Users > Your Name > App Data > Local > FenestraPro

The file will be named CustomStandards.db. Care should be taken not to delete the file from your own machine as this may cause the application to display an error as it will be referencing this file. The file may be copied and pasted to another location or emailed to a colleague etc.

Other files in this location store the results of analysis to date, log files of progress, error messages, Custom Groups and Glazing Specifications that have been created etc. Likewise, these may be shared with colleagues if information is to be common.

Category: General
  • Custom Groups created in one method relies on the Surfaces that FenestraPro creates in that method. Since both options for analysing Detailed models will create, name and manage the number of Surfaces differently, any Groups created in one method will not apply to the other. If another method is used to analyse the same model, Custom Groups would have to be created again.
  • Custom Standards created in one method will be available in the any other method as these values can be applied to all model types.

If you have already calculated with Shading Factors on and then calculate Solar Loads without Shading Factors, results may stay at the lower figures. FenestraPro may need to be re-launched to reset the results and allow the results to update.
