Window "tint" saves fuel through reduced AC load (duh, but nice to see quantified)

Anyone else see this?

I don't think it's specifically about "tint", but I put that in the title becuase it's shorter than "infra-red reflective glazing".

Quote:
"Over repeated UDDS cycles, the Sungate EP glazing reduced the air conditioning power and resulted in an increase in fuel economy," said John Rugh, Senior Mechanical Engineer for NREL. "The adjusted, utility factor-weighted fuel economy increased from 36.8 to 42.9 mpg for the Sungate EP thermal load case, while the adjusted, UF-weighted electrical energy consumption was roughly equivalent."

Window tint should be in the mods list. It didn't occur to me before because I don't have AC, and probably wouldn't run it much, if at all, if I did. But everyone's different.
