Hello. I am trying to reproduce the texture of the glass panels on this
building. It is very reflective but also seems to have a dark tint. I included a
picture because I can't describe it better. Thank you.

Hello, the following POV keywords are going top be your friends:

ior
fresnel
albedo
conserve_energy

Don't go too far into other eye candy for such outside landscape, to avoid
computational power/time waste.For the same reason, if you look very carefully
to your reference picture you'll notice this material shows no glare at all and
so you could also simply not use any specular nor phong, just focusing on
(dark)diffuse and reflection (with its two values). I look forward to see the
outcome of what appear as a basic but may end up a rather fundamental challenge!

just to add, 5-vectors and the filter/transmit may be worth playing with too, I
guess.

I'd go for something similar to this as a starter :
texture{
pigment{rgbt 1}
finish{diffuse 0 ambient 0 specular 1 fresnel reflection{1 fresnel}}
}
interior{ior 1.5}

With maybe a layered texture with the top one something similar to :
texture{
pigment{rgbf<0.75, 0.75,0.75, 1>}
finish{specular 0 diffuse 0 ambient 0}
}

This is to simulate the reflective surface being behind some tinted glass.

I suspect it have a metal film coating.

Took a finish from the Metals.inc file to make the finish for the texture. Not
bad, I think. Building finished. Didn't bother with the doors.

Scratch that. Added a missing base and added the revolving doors. The window
panels should be slightly different next to the doors, but I got lost in the
coding I made. Maybe I'll figure it out later, but frankly I am sick of this
building, and so much want to be done with it.
