Can anyone tell me if 3d max is certified daylighting calculation
software? I guess what I'm asking is, is it suitable for use in design
engineers to use as proof of compliance with design standards?

Hi Marina,
Looks about right to me -- does it reproduce the combined
transmittance and reflectance you're measuring? Are the interfaces
separated by an air gap, or are some/all layers laminated with an
optical adhesive? In the latter case, the functions in glaze2.cal
won't compute the correct combined transmittance and reflectances.

Hi Robin, hi All
yes I want to simulate a laminated glass in a double glass system.
This
laminated glass is a prototyp of a glazing system and there is no
information about it anywhere. It is also a quite complicated system
with embeded coating and interlayer and I can get its description from
Optics5. That's why I think the way to describe this glasses are with
the spectrometer measurements.
I am still not sure anyway if I describe the glasses propertly.
Does anybody knows if this is right like this:
#window geometry:
double_glazing_a polygon window
0
0
12 0 -0.18 0
0 -0.18 3.34
4.13 -0.18 3.34
4.13 -0.18 0
#window material:
void BRTDfunc double_glazing_a
10
if(Rdot,cr(fr(rf1_r),ft(t1_r),fr(rf2_r)),cr(fr(rb2_r),ft(t2_r),fr
(rb1_r)))
if(Rdot,cr(fr(rf1_g),ft(t1_g),fr(rf2_g)),cr(fr(rb2_g),ft(t2_g),fr
(rb1_g)))
if(Rdot,cr(fr(rf1_b),ft(t1_b),fr(rf2_b)),cr(fr(rb2_b),ft(t2_b),fr
(rb1_b)))
ft(t1_r)*ft(t2_r)
ft(t1_g)*ft(t2_g)
ft(t1_b)*ft(t2_b)
0 0 0
glaze2.cal
0
9
0 0 0
0 0 0
0 0 0
where I just have to substitute the next measured data:
Red: 700nm -- rf1_r rb1_r rf2_r rb2_r t1_r t2_r
Green: 546nm -- rf1_g rb1_g rf2_g rb2_g t1_g t2_g
Blue: 436 -- rf1_b rb1_b rf2_b rb2_b t1_b t2_b
Thanks again,
Marina

Are you talking about average daylight factors and bre guidance? The
bre does make mention of "computer simulation" but doesn't go into
detail.
In my experience I would either use radiance or the light studio
radiance plug in for 3ds max for accuracy.

Yes daylight factors but in general terms. I do lots of artificial
lighting design using Dialux which is CIE accredited and the output is
recognised as acceptable for building compliance. I just wasn't sure if
3d max was?
Thanks for responding so quickly tho, much appreciated.
