[Radiance-general] Difference between climate data and Radiance data.

[濱田裕章]

Dear all,



I’m going to study distribution of solar radiation in buildings in the city
by using GIS data.

I’d like to match a climate data with Radiance data. But, I couldn’t get
the same value.

Does anyone know the idea how to match climate data and Radiance data?

My method is below.

Obtain an illuminance by using Pvalue command.

views file is below.

rview rvu -vtl -vp 0 0 10 -vd 0 0 1 -vu 0 1 0 -vv 180 -vh 180 -vo 0.0 -va
0.0

skies file is below.

bash file is below.

pvalue -h -H -d t1_1.pic | total -m | rcalc -e '$1=($1+$2+$3)/3*16'>t1.dat

The result is below.
