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.
