Daylight autonomy

[Michi]

I would like to calculate the DAYLIGHT AUTONOMY. is it possible in IES-VE?
Which program should I use? Radiance or FlucsDL?
if it is not possible, how can I calculate the daylight for a annual simulation instead that for just one istant?
Thank you very much!

Hi,

I believe you could calculate this using Radiance sensors, then run an Apache Simulation and you can view the daylight illuminance levels for each room in Vista

Well for the sensor part with radiance, you only get the daylight for a single point during the entire year. So if you want to use this, you should do a kombi of both the radiance with sensors and a daylight calculation of a 10k overcast sky to see how the room is compared to the point.

yeah follow up to this which was suggested by one of my colleagues but that I originally neglected on the grounds that it's not really practical would be to zone your rooms e.g. in 2m x 2m blocks so you could place sensors uniformly across the room, you can then compile those results from Vista and take it from there

Thank you very much for your help!
