Hi all,
Does anyone know of a way to get vertical illuminance at a specific point in Radiance?
Thanks,
Hana

Hi,
You can give the direction vector in rtrace command to get irradiance
value. Check rtrace manual.
For example: If you assign input arguments "xorg yorg zorg xdir ydir zdir"
as "xorg yorg zorg 0 0 1" then you will get irradiance at the horizontal
plane (or floor of the building). Similarly, you can do for other vertical
planes by assigning their correct location and direction. To convert
irradiance to illuminance, see this command:
$ echo xorg yorg zorg xdir ydir zdir | rtrace -I [options] yourScene.oct |
rcalc -e ’$1=$2;$2=179*(.265*$4+.670*$5+.065*$6)’
Regards,
Vaib

Yes.
If you want more details, you'll have to ask a more detailed question, describing your input (do you have a weather tape?) and how you want to average or accumulate your data (any operable systems in play?), etc.

Hi Greg, Vaib and all,
About my question, I asked earlier, here are more details about the problem.
I am doing daylight analysis for a room using Radiance with output showed in Ecotect, I have the drawing with all required details ( the latitude, longitude, weather data, time, date and surface materials and colour) I already did calculate all the illuminance points at 0.8m on the grid created in Ecotect and got the result I need. Know I need to calculate the vertical illuminance for similar point I have in the grid that just facing the window opening as I need these readings to calculate the glare index for room I am studying it.
The problem that I am no that expert in using radiance, so is there any simple tips can help me in solve this problem?
I do appreciate your help in this matter
Many thanks and best regards,
Hana
Hi Hana,
If I understood your question correctly, you need to calculate illuminance
on a vertical grid in Ecotect. I guess you have already calculated
illuminance on a horizontal grid at 0.8m height above ground (working
plane). If this is correct, then please see the image attached.
I also started with Ecotect, but I am not sure it has its own user group.
But in this group too, there will be people who are experts in Ecotect.
Hope it helps.
Regards,
Vaib

Hi Vaib,
Thank you so much for your response.
Yes, I need to calculate the vertical illuminance on 0.8m facing the opening side.
I did not find the attached image you talked about can you resend it please.
Best regards,
Hana
