[Equest-users] WWR calculation by equest

[deepika khowal]

thank you Carol and John

I also verified with ASHRAE and it says
"Window-Wall Ratio: The window-wall ratio is the ratio of vertical
fenestration area to gross exterior wall area. The fenestration area is the
rough opening, i.e., it includes the frame, sash, and other nonglazed window
components. The gross exterior wall is measured horizontally from the
exterior surface; it is measured vertically from the top of the floor to the
bottom of the roof. The gross exterior wall area includes below-grade as
well as above-grade walls. It is necessary to calculate the window-wall
ratio with all compliance options, since this
information<http://answerpot.com/showthread.php?2136111-Fenestration+and+Window+to+Wall+Ratio#>
 is need with the prescriptive option, the trade-off option, and the energy
cost budget<http://answerpot.com/showthread.php?2136111-Fenestration+and+Window+to+Wall+Ratio#>
 method."
