BRE Daylight Factors¶
The BRE Daylight Factors tool is located in the Add-Ins section of the ribbon:
This tool can be used to calculate daylight factors for each zone in the model according to the BRE method.
This tool will replace any existing daylight factors that may have been calculated by the 3D modeller.
The daylight factors produced by the 3D modeller are considerably more accurate than those calculated via the BRE method.
The BRE method of calculating daylight factors is outlined in the SBEM technical manual; for more information about the difference between the BRE method and the 3D modellers daylight engine, click here
