Sorry Richard - just re-read your post. I will pursue a specific answer,
but if you need sources for your info, they would likely be:
Mil-Std-210
Mil-E-87145
Def-Stan-0035
SAE applied thermodynamics manual
ASHRAE manual
They can be had at most college libraries, I'd imagine. When I mentioned
day type, there are military standard days with different "risk" factors.
Like Mil-Std-210 hot day can be 120 deg F with no humidity, 113 with
humidity, 103 with high humidity, etc. For the solar load stuff, the angle
of the sun and the clarity of the sky count ("view factor" for the engrs),
but that would be in the sources listed and we can make some assumptions.
Later,
Ron
