The original TMY2 files contain global horizontal illuminance data
as well as direct normal, diffuse horizontal, and zenith illuminance.
See TMY2 format information on the NREL web site:
http://rredc.nrel.gov/solar/old_data/nsrdb/tmy2/
Illuminance data was calculated using luminous efficacy models
developed by Perez:
http://rredc.nrel.gov/solar/pubs/tmy2/appendixa.html#calc
(The EnergyPlus weather files maintain the illuminance data.)

Please respond to
daylight7group
Does anyone know of a program or a procedure to convert TMY2 solar
radiation data into horizontal daylight illuminance?
Thanks,
Robert
