Can I use Revit to document this credit?

Can electrochromic glazing qualify as a glare control device?

Do I actually need to submit the USGBC Daylight and Quality Views calculator?

What types of glare control are acceptable for this credit?

My office space will have cubicles with high partitions. Should I include those in my model?

Can I mix and match daylight analysis methods? What if one room meets the illuminance thresholds but not the ASE limit?

What daylight simulation software can I use for LEED compliance?

If I’m pursuing Option 2 or 3, can I average the compliant square footage between 9 a.m. and 3 p.m. for a space and use the average as the compliant square footage?

Is it possible to combine Options 1 and 2 for different spaces in the same building?

Their fact sheet states that AGI 32 can only do LEEDv4 option 2, which is single point in time calculations. So the answer is no. I have used AGI 32 for single point in time calculations and compared them to actual space and the average was about 3-8% difference. A bit larger difference under cloudy skies and more accurate under clear. Daylight analysis is analyzing the daylight performance of space. Spatial Daylight Autonomy is a metric used to measure daylight performance. DaySim through Diva for Rhino, Daysim, SPOT, and light stanza will perform sDA
