NC-v4 EQc7:Daylight

Analysis areas for large building

Hi, For EQc7: Daylight. Option 1, spatial daylight autonomy (sDA): In IES LM-83-12 section 2.2.6 Blinds/Shades Operation it says that the analysis area for obtaining the blind operation schedules may never exceed 10,000 sf. Currently we are designing a massive building of 400.000m2 . For a building of this magnitude will it then be sufficient, to obtain the operation schedules for representative sections of the building, and then map those to the rest of the building?

I don't recall this specific requirement. My guess is to ensure you don't apply same blind operation schedule in large room. In real world, you want to have different schedule for several sections depending on the window orientation and room usage. You can use typical room if you think each section has same daylight pattern. However, You can also apply section by section by splitting grids.
