Environmental Conditions: Solar Radiation

[Shelby Smith]

Hello,

More of a general question...

I have been working on modeling glass/surface temperatures under various environmental conditions. For conditions like temperature and wind speed, I can simply look up climate data for the particular area I am looking at. For the input for "Direct Solar Radiation," I've used a few different resources (including NREL's Solar Radiation Data Manual for Buildings https://www.nrel.gov/docs/legosti/old/7904.pdf), but wanted to know if LBNL (or anyone else on this forum) had other suggestions for tables or charts with solar radiation data. (Including information for North/South/East/West elevations.) I had heard that some of the older ASHRAE manuals had some comprehensive tables, but I have not been able to find them.

Any suggestions are appreciated,

Shelby

Are you familiar with the national solar radiation database?  These data can be used with a solar radiation model (example: Hay and Davies, Klucher Model, HDKR)  to determine the values you're looking for.

I found the NSRDB but am still learning my way around the program. Thanks for the tip about the radiation model- that is the piece I was missing.
