Bill,

Sorry, but I can't help you out on your daylighting question.  I'm also sorry, but the song was AFTER my time.  I'm more into 60's & 70's music and boogie woogie and piano blues artists who died 50 or more years ago. :)

Subject: [Equest-users] Input function with daylight factors for accurate daylighting

I am modeling a building with many clerestory windows of various orientations in a complex roof geometry. I would like to accurately model the daylighting savings in eQUEST. Has anyone had luck creating an input function that uses daylight illuminance factors, as described by Steve Baker<http://simulationresearch.lbl.gov/dirpubs/complex_dayltg.pdf> back when Bush Sr. was president and this song<http://www.youtube.com/watch?v=9EcjWd-O4jI> was a Top 10 hit? "Limitations of the Daylighting Calculation" and an "Example of Using Measured Daylight Factors" using an input function are described in the DOE-2 help.

Thanks,
Bill
