where can i find the solar heat gain factor for nyc and nj? 1

[illhp]

the title explains it all.

 

[25362]

FWIW Perry VI table 12-5 and CRC's Handbook of Chemistry and Physics give daily solar radiation data over the year at various latitudes. If SHGC is what you want, there are a large number of sites that may be helpful, for example:

http://www.energycodes.gov/support/SHGC_faq.stm

http:

http://www.eere.energy.gov/consumerinfo/refbriefs/eb2.html

http://www.netcentral.co.uk/eclectic/eecoenv/lecture1.html

At least one of these may direct you where to find the specific data you want.

Good luck.

I found a more useful source. Try:

"Principles of Heating Ventilating and Air Conditioning" , Ronald Howell et al, A Textbook with design data based on the 1997 ASHRAE Handbook- fundamentals, 1998 ASHREA
<

Also, for individual cities anyhwere on the planet, 5-10 years or hourly data is available on CD rom from NOAA. Excellent for computerized simulation of a process that is dependent on changin ambient conditions.
