How To Calculate Daylighting Using FenestraPro

When a specific Façade is selected in Façade Manager more detail is displayed from this parent Façade, such as its child surfaces. To view the Results for a specific Surface, clicking into the bar chart will display results for that Surface only.

To go back to viewing all results, click on the arrow button at the top of the window (this will display when a specific Surfaces are selected). This will also uncheck any previous selections in the Façade Navigator.

If several Surfaces have been selected and the Charts display these results, clicking on any Surface bar in the Chart will select just that Surface and display monthly values. Using the roll up arrow on the top right of the Charts panel will return to viewing all the Facades.

Changing the Glazing Specification for windows or Curtain Walls may affect the Visual Light Transmittance value. This can be viewed in Type Properties of Revit or in FenestraPro Linc. This will affect the Daylighting results since a lower value for VLT will restrict light transmission more than a higher value.

Adding shading devices or fritting to glazing will also affect the Daylighting Results. Fritting in FenestraPro has settings for both coverage and Transparency. A higher coverage will reduce daylight. A lower value for Transparency of the fritting (meaning that it is more opaque) will reduce daylight more than a higher value.

Note: for Shading devices to affect the results, turn on Shading Calculations in the Building Manager.
