[Bldg-sim] Advise on Daylighting program

[Paul Hay]

Thanks for your assistance Khalid! I hadn't used the Average Daylight Factor equation since undergrad years: totally forgot about it. I should have been more specific when I referred to 'window options', but I meant window size, distribution and location (i.e. orientation, head-height, etc.).

Paul, it is not clear for me what you mean by window options; if u mean window area, then u can use the Average Daylight Factor equation which is a very simple equation where you can decide on window area and glazing transmittance. The equation is based on the Overcast Sky as a design sky, however, If you can decide on the type of design sky  (the external horizontal illuminance) then you can use such equation.
 
If you are looking for a program that can do daylighting analysis, then ther are a lot of programs such; Ecotect, SPOT, DAYSIM, SUPERLITE 2.0,  etc …
If want to study the effect of window area on energy consumption, then u need to use energy simulation programs, such as EnergyPlus and DOE-2

Can anyone advise if there is a daylighting program that uses intended illumination levels to generate window options? I remember reading about one long ago from an article by Eliyahu Ne'Eman: I believe from LBL UC(Berk.). I never heard of it since that article in Energy & Buildings.
