Hi ! Running daylighting analysis on a 4 stories building, assuming 3 floors have more than 75% of natural daylight between 10fc-500fc in regularly occupied space, whereas the last floor has less than 75%, then should I assume I don't pass the credit ? how is the credit calculated when having multiple stories ? Thank you !

Olivier, Compliance is based on the total regular occupied square footage. So being over the 75% on three floors, that area being over 75% could make up the difference for the fourth floor. To properly calculate the credit you need to complete the Supplemental Daylight and Views Calculator. Each space should have its own line and the compliant area should be noted for each based on the simulation results. The values will be automatically calculated.
