I am working on a project that was certified under LEED EB v2. This project is now going for recertification under v3 and I am trying to figure out whether or not we will receive IEQc2.4: Daylighting again.
We are following Path 2: Prescriptive. The requirements for both versions are very similar; however, the equations to determine the daylight factor/ daylight zone are a little different. Does anyone have expereince with this and/ or know if the new equation makes a significant difference to your result?

Our experience has been that the change in calculation methodology hasn't significantly changed the ability for spaces to comply with the credit. There are some differences, so it is, of course, a case by case basis, but generally we have found that spaces that complied before 2009 still comply in 2009.
