I'd like to ask that do you know how to create a fisheye picture of illuminance rendering? illuminance map is only the r

Thank you very much , I attached the files via the link. link text

Thank you for your suggestions, I create a 360 degree sky, but the rtrace program popes up the following erro 'rtrace: e

Thanks. I understand that if I want the irradiance values(W/m2), I need to put radiance values for -b and irradiance fo

Thank you Andrew, the way you set parameters for 'rtrace' is very useful. Since, there are lots of parameters, I wonder

Regarding the options of gensky, I used -b because I intend to create the CIE standard 15 Skies, the zenith brightness w

I create a txt file containing the coordinates of four points in a room, why did the illuminance results become so much higher ? The simulation results were several times of the results when I used individual txt file for a point. For example, for calculation of the illuminance of four points in a room, first I create four txt files containing the coordinates, the results were around 100 lux, but then, I put the coordinates of the four points in a single txt file (one point in each line), the results were around 800-1000lux.

I don't know why? Any suggestions would be appreciated. Thank you.

Great thanks, I found the problems. I changed the size of obstructions and ground plan (200m long). What is the value o

You mentioned that in E+ there is no need to put holes in walls for windows, so I wonder how EnergyPlus deals with the w

Thanks a lot. I tried to cut down the size of the ground and obstruction (200m), and the result seems reasonable. I hav

Thank you. Since I do not have 10 points to upload the files, I will just paste all the texts here: Geometry:(reflectan
