LEED Views Documentation

Ahh- time to document the dreaded LEED Views credit. I must admit that this is one of my least favorite credits to document. It doesn’t take any complex calculations or any real technical know-how, but calculating good old IEQ Credit 8.2 can be a real time hog. I also get questions about documenting this credit quite often from co-workers:

Q: Do I really have to graphically show “view” vs. “no view”?

A: Yes.

Q: Do I have to draw sections showing a view at 42″?

A:Yes.

Q:Do I have to include a spreadsheet with the breakdown of ares of each regularly occupied space?

A: Maybe.

LEED for Schools 2007 (v. 2.0) does not have an official views calculator nor does it have spaces for this information on the official credit template like LEED NC 2.2 and LEED 2009 rating systems do. I have, in fact, gotten away with only submitting a graphical representation of floor area with views in the past for LEED for Schools, LEED for Core and Shell and LEED EBOM. Recently, however, the GBCI reviewers seem to be “cracking down” on teams that do not submit a spreadsheet breakdown of which spaces have views and for what percentage of their area. I recently even had a LEED for Schools reviewer demand that I use a views calculator that is only available by downloading it through a registered LEED for New Construction project in LEED Online (glad I had one!).

With all the confusion, I thought it might be helpful to provide a set of sample documentation uploads (complete with excel spreadsheet for LEED for Schools 2007 projects) minus the template itself. You can access a sample graphical plan here, a sample section here and the excel spreadsheet here.

I also have a few tips:

  1. Let Revit (or AutoCAD, I suppose) do the area calcs for you.
  2. Pick a “typical” section or two- no need to go crazy
  3. Remember that only windows with a direct 42″ line of sight count- no high windows or clerestories
  4. You can count 100% of the area of a private office as compliant if at least 75% of the office has a view at 42″ and you can count 100%.
  5. Think about excluding your gym if you’re doing a school by using the CIR dated 3/22/2007 (ruling date). Ball meets vision glazing is not a good situation
  6. Bone-up on the definition of regularly occupied spaces. Yes- a custodial workroom or a kitchen are considered “regularly occupied”

Good luck on your own documentation!

  1. For the window to qualify as having a view does it have to have a height of 30″ – 90″. A poster in LEED User stated this and no one rebutted the statement. Or does a window of any height qualify as long as it is not totally outside those ranges (with the understanding that it must be in direct 42″ line of sight.

    1. Eric- I know that the credit language on this is a bit confusing. I have always counted all windows that occur between 30″ and 90″ (not necessary occupying this entire range) as long as they have a direct line of sight at 42″. In fact, it is very common for us to use a 36″ sill height and we have never had any trouble getting the credit because of it. I can’t guarantee that will always be the case as some reviewers take different approaches, but I would encourage you to count any and all windows that have that 42″ line of sight.

  2. Thank you for your posting your tips here. I have a very basic question regarding the plan view diagram– how do you determine the angle of the “view” lines? from the glazing perimeter into the rooms? Similar question for the section view diagram. Are you bringing the 42″ line into the CENTER of the room and then drawing an angle up from there to 90″ (or top of the glazing)?

    Thank you for your help,

    1. Lucia- I determine the angles from the windows by drawing a diagonal line from the exterior jamb to the interior of the opposite jamb of the window and then extending the line into the space. For the section view, I am simply drawing a horizontal line and then an angled line either to the top pf the window or the top of the 9′-0″ height described by the credit for vision glazing.

  3. Hi, Thank you for sharing this information!
    I have a couple of questions,
    When you’re drawing the view lines in plan how do you know when to take the line from the perimeter of the window to an interior partition and when not to do it? for example room 132 and room 174
    Also, for the horizontal view, how do you calculate the compliant area? if it’s 90% or more you take the space area; and if its less than 90% you take the area with Direct Line of Site to Perimeter Glazing?
    Thanks a lot for your help!
