Dear all,
I am doing daylighting modeling for a project, I tried Radiance using ruby scripts provided by NREL as a command line interface but for some reason they are returning errors right after executing them.
Anyway, I decided to use EnergyPlus v7.2 daylighting modeling, but the fact it doesn't support more than one illuminance map per zone forced me to divide zones into smaller rectangular ones, and to connect these "sub-zones" visually, to do that, I used hypothetical windows with 0.99 transmittance as hypothetical separators between these sub-zones and connected them using "outside boundary condition object" fields.
Now illuminance maps inside sub-zones with no external windows are returning the same values at all map nodes (100% uniform map, which values are maybe equal to the average value) and this value is very close to the nearest value (by location) in the adjacent space which has external true windows.
Am I doing right? I need to know how to model daylighting so that it complies with BREEAM HEA 01 Visual Comfort Credit.
Thank you very much.
Hisham
