Thanks again. I have changed the output_units from 2 to 1 in my file*.hea
and saved it. But Daysim still considering illuminance sensors. How could I
reload my file*.hea in order to Daysim can consider irradiance sensors?
Besides, I have changed the sensor_file_unit from 0 to 2, but Daysim still
considering illuminance sensors.
Many thanks

Content-Type: text/plain; charset="us-ascii"-I haven't used the new version of DIVA yet, so maybe someone else can
answer this question more detailed. I know you can go two approaches,
either you define a node in W/m*m and run an annual simulation with daysim
OR you run an irradiation map with gencumulativesky ,but I'm not sure
where to invoke the latter one in the new version.
In Rhino go to Metrics >>Daylight Grid-Based >> Daysim-Based hourly Method-------------- next part --------------
