IECC 2015
Came in here to look for additional information regarding the definition of "Daylight Zone under skylight area" seeing how the 2012 definition was eliminated in 2015. I found my answer in the March post by George M.
Yes it answered my question, but lead to another one and possible issue.
We are doing a Zone 4, F1 facility of approx 50,000 SF which will have several large open areas with average roof heights of around 32' (no ceilings). We are planning on using 4'x4' skylights spaced at approx 26' OC for most of the roof area. Using the IECC 2012 we were able to achieve the Minimum Skylight Fenestration Area calculations mostly in part due to the "one-half the distance to adjacent skylights" that was part of the "Daylight Zone; Under skylights" definition. It took into account the daylight overlap. Well, that's gone now.
To be honest, I do not see any possible way of adjusting the skylight size and/or spacing to make the MSFA calculation work with the floor to roof heights we have. Am I missing something?
Thanks in advance
EDIT: Never mind. Got it to work out. I was calcing it as a single skylight. When I figured the whole area with all the skylights, the number came in above what was required. Phew.
