Hello:
IECC 2015 ed. Section C402.4.2 Minimum Skylight Fenestration Area:
Working on a project where this "new" requirement will apply to a space in the building I am designing, since the space is over 2,500 sf and directly under roof (the space is a high school gymnasium). We will use skylights and vertical fenestration to daylight the space; however, the skylight manufacturer can not provide any of the data required to run the calcs / equations listed under this section of the code. Plus, I am not an engineer so these kind of calcs are not really my baileywick anyway. Third thing is I honestly admit I am a bid confused about what this section of the code is actually requiring.
Having a better understanding of the definition of "Daylight Zone" would be helpful. The Chapter 2 definition is a bit weak. If an area is daylit by skylights is that area considered a Daylight Zone, or does this term only apply to areas daylit by vertical fenestration?
Can anyone shed some light (no pun intended) on what this section of the code is actually requiring and how to demonstrate compliance? I apologize in advance because I do not own the code commentary for the 2015 edition of the IECC. If someone could 'enlighten' me, it would be much appreciated.
Thanks
