ASE component - zero hours




I’m working with HB + to calculate ASE with 3PH method. The calculation was completed without issues.
It seems that ASE component not worki properly since it gave zero number of hours ASE (see image below)

While if I check the illuminance for a single hours the result give me lux leve upper than 1000 lx (which is the ASE illuminance threshold)

Any suggestion is appreciate.



Hi @giorgio_butturini, 3-Phase doesn’t have a separate calculation for direct sun contribution and that’s why you get all 0s. You should use Daylight Coefficient or 5-Phase recipes for this case. They both calculate the direct sun radiation and hence can be used for ASE calculation.

We should add a proper error message for using 3Phase for calculating ASE instead of returning 0s.
