Hi Amanda, The latter part of your question is correct. If the head height of the vision glazing is 7 feet tall, the area with views that can be included in the EP calculation are regularly occupied spaces within 21 feet of the window.

Hi Carlie, I'm also trying to understand this 3rd pathway. How can the head height be 7 feet tall if vision glazing is from 30" to 90"? What exactly is the "head height"? Thank you.

I also need to know how to calculate the "view factor". Thanks Carlie!

Hi Ruben, The head height is measured from the finished floor to the top of the window. In the scenario described above the top of the window (or head height) goes up to 7 feet tall, which falls within the vision glazing area is between 2'-6" and 7'-6" The "view factor" is defined in the Heschong Mahone Group study, as described on page 571 of the BD+C Reference Guide - also check out the LEEDuser discussion on this subject under LEED-NC 2009 IEQc8.1 dated 10/09/2009 and 7/09/2010. Hope helpful!
