Daylighting Analysis Results

Hi,
I am working on a Daylighting Analysis and the results seem too low. My understanding is that the percent daylighting that is being graphed is the percent of time from 8am-6pm that the lux is over 300. Given the size of the windows in this test, the percent of daylight should be much higher than 16%. Is there something I am doing wrong?

Hi @Applerox, looks like you’re visualising daylight factor, not daylight autonomy (which is what you’re describing, albeit I think the default is for 8am-5pm).

Those results look reasonable for a daylight factor analysis with that model set up.

So is this study showing an average of all 24 hours?

I’d recommend having a look at this website, it has good explainers of various daylight metrics.
